In the Northern Hemisphere the fall
season is upon us, and I trust that you
all had a wonderful summer, or winter
period. Many of our Affiliated Societies
have been quite active this past quarter.
My summer was busy with various
activities. In June, I had the opportunity
to visit members of the Iberian Society
for Trenchless Technology (IbSTT) in
Madrid followed by attending the 2011
Scandinavian Society for Trenchless
Technology (SSTT) Conference in
Copenhagen. It is refreshing to see the
enthusiasm and dedication to trenchless
of these two long standing societies.
In July, I attended the Singapore
International Water Week (SIWW) and
visited with the Singapore Society for
Trenchless Technology (SgSTT). ISTT was
a supporting organisation of this international
event that attracted over 14,000
delegates from around the world. I was
truly impressed by the organisation of
the event as well as the excellent networking
opportunities. Derek Choi and
I had the opportunity to briefly meet
Singaporean Prime Minister Lee Hsien
Loong. The Prime Minister is very
knowledgeable about water and sewer
infrastructure issues, and is a real champion
for investment in this area. I also met
and discussed trenchless technologies
with Mr Dinesh Gunawardena, Sri Lankan
Minister of Water Supply & Drainage, and
Mr Karunasena Hettiarachchi, Chairman
of the Sri Lankan National Water Supply
& Drainage Board. My plan is to try and
meet with both of these gentlemen during
a visit to Sri Lanka in December.
Trenchless activity along with government
support make this country a potential for
a new society.
In August, Dr Dec Downey, John
Hemphill and I attended No-Dig South
Africa 2011 in Pretoria, hosted by the
South African Society for Trenchless
Technology (SASTT). This was the first
ever ISTT-sanctioned event held in the
African continent. An excellent technical
program and sold-out exhibition should
provide momentum to increase trenchless
activity in the region. I also had the opportunity
to visit with the Colombian Society
for Trenchless Technology (CISTT) in
Santa Marta. CISTT partnered with La
Asociación Colombiana de Ingeniería
Sanitaria y Ambiental – ACODAL during
its 54 th Annual Congress. It is encouraging
to see our Affiliated Societies working
together with other local organisations.
In September, the Czech Society for
Trenchless Technology (CzSTT) held its
16 th Annual Conference on Trenchless
Technology in Melnik. Unfortunately, university
commitments precluded me from
being able to attend this event. John
Hemphill attended the conference in my
place and delivered my presentations.
The CzSTT is one of our more active societies
and always has an excellent annual
event. The China-Hong Kong Society for
Trenchless Technology (CHKSTT) also
held its bi-annual trenchless conference
in August. Vice Chairman Derek Choi represented
ISTT and delivered the opening
address. Once again, the CHKSTT had
a successful technical and exhibition
program.
In the next quarter, there will be trenchless
events in Brisbane, Australia (ASTT:
3–6 October), Beijing, China (CSTT:
26–29 October), and Istanbul, Turkey
(TSITT: 17–18 November). Additionally,
the ISTT is supporting Trenchless Middle
East 2011 from 10–11 October in Dubai.
Dr Downey and I will be giving a Trenchless
Masterclass at the conference. Exhibition
space for the event sold out months in
advance, suggesting that perhaps this
region is one to explore for a possible
new Affiliated Society.
I look forward to another excellent
quarter of trenchless activities and hope
to see you at a future event. It is hard
to believe how fast time has flown by
this year. Before we know it, we will be
entering 2012!

executive director’s report
October 2011 - Trenchless International
John Hemphill
Istt Executive Director
ISTT and the 26 Affiliated Societies that
are ISTT members have been busy, actively
pursuing programs to advance the science
and practice of Trenchless Technology and
to promote education, training, study and
research of trenchless for the public benefit.
At the ISTT annual meeting held in Berlin
earlier this year, I was struck by how much
regional trenchless societies have done
and are doing to advance these shared
objectives. Affiliated Societies cover many
regions of the world, which suggests that
trenchless is being well served by the collective
efforts of the regional societies.
Chairman Sam Ariaratnam has been personally
involved in many regional society
programs by serving as a keynote speaker
and conducting training courses at these
events. I also had the honour to help out.
In September, I will participate in the Czech
Republic’s 16 th Conference on Trenchless
Technology to be held in Melnik. The CzSTT
program is highly regarded and receives
strong member support. I also am excited to
be participating in No-Dig South Africa 2011,
which is co-hosted by ISTT and SASTT.
No-Dig South Africa will be held in Pretoria
from 23–24 August. These events are but
two of the many, many programs hosted by
ISTT regional Affiliated Societies. I believe
you will find the summary of the plans, programs,
and activities of the ISTT Affiliated
Societies for 2011–12 described in the following
paragraphs as impressive as I do.
Starting in the Northern and Central
European regions, Austria, AATT, will hold
its annual conference from 18–19 October
in Steyr. The conference attracts approximately
200 participants. AATT also prepares
a newsletter and maintains a website for
disseminating information on Trenchless
Technology. The Czech Republic, CzSTT,
will hold its 16 th Conference on Trenchless
Technology from 13–14 September in
Melnik. Finland, FiSTT will hold trenchless
training courses and has arranged a site visit
to Helsinki. FiSTT also arranged a fair excursion
for FiSTT members to the 2011 No-Dig
in Berlin. France, FSTT held its 9 th VST from
15–17 June. This event was well attended,
with more than 90 exhibitors and more

Microtunnelling through New Jersey
The Borough of Carteret, located in New Jersey, US, has awarded Cruz
Contracting a $US2.2 million contract to complete sanitary sewer line upgrades
using microtunnelling.
A 51 inch diameter steel casing pipe will be installed across the New Jersey (NJ)
Turnpike, and a 30 inch diameter sewage pipeline will then be installed within the
casing pipe to provide a new interceptor sewer to serve all users in West Carteret.
Construction of the new pipelines will face many challenges, including building
across active rail lines, regional petroleum supply lines, facilities, as well as the north
and south-bound lanes of the NJ Turnpike.

From concrete to PVC in California
Preparations are underway in Sonoma Valley County, located in California,
US, for pipeline construction projects, including replacing a 5,700 ft section of
main sewer.
The existing sewer, which is 50 years old and constructed from reinforced
concrete pipe, will be replaced with new PVC pipe material ranging from 30–42
inches in diameter.
The Sonoma Valley County Sanitation District’s sewer replacement project is
a component of its capital improvement plan to replace ageing and structurally
deficient pipes that collect wastewater and deliver it to the district’s treatment
plant.
Pipe jacking in Hong Kong
Intercepting drains were recently constructed at Queen’s Road Central, Hong
Kong by pipe-jacking.

Pure acquisition of inspection business
Pure Technologies has purchased Salt Lake City-based pipeline inspection developer
Electromechanical Technologies for $US3 million.
Electromechanical Technologies has developed extra-high resolution, magnetic
flux leakage systems, which overcome the challenge of inspecting internal cement
mortar lining common in water pipelines.
Philippines gets closer inspection
Maynilad Water has invested in a CCTV acoustic leak detection system, from
the United Kingdom, to bring down water loss in the area.
The JD7 LDS 2010 'Investigator' system enables pressurised pipe inspections
of pipes with diameters 400 mm and smaller without interrupting water service.
Aside from detecting leaks without interrupting services, the system lessens
traffic obstruction by minimising road excavations necessary to check the pipes.
Upgrade work in Tottenham
Pipe bursting in Somerset
A 56 year-old pipe in Cucklington, located in the south west of England, will
be replaced using pipe bursting as part of Wessex Water’s ongoing water supply
improvements within Somerset.
The project, worth £250,000, is expected to be completed in late October.
Thames Water will be focusing on upgrading a large Victorian water main in
Seven Sisters Road, Tottenham, United Kingdom.
The current cast-iron main is also more than 100 years old and is no longer
able to cope with the water pressure flowing through it, resulting in a number of
bursts in recent years.
More than 1 km of the 24 inch pipe will be strengthened and relined, minimising
disruption and reducing the length of time it takes to do the work.

Bigger and better No-Dig
The Netherlands Society for Trenchless Technology (NSTT) will be holding its second No-Dig event from
6–7 October 2011 at the Expo Haarlemmermeer, located in the Netherlands. The event will include an exposition, drilling
contest and live demonstrations. The 2011 No-Dig Award will also be handed out at the event.
The second event is following on the success of last year’s event. The NSTT No-Dig Award 2010 went to the Gasunie
project for using direct-pipe technology in the crossing of the Hartelkanaal in the Port of Rotterdam. Enno Freese. Project
Director Large Projects at Gasunie received the award from President of NSTT Theo Everaers.
The Direct Pipe Method is a combination of a closed front drilling and HDD using two new elements, a pipe thruster and
a special tunnel drilling machine. The pipe thruster pushes the pipe into the soil, while the tunnel drilling machine drills away
the ground in front of it and removes the grit through the inside of the pipe. Thanks to this technique it is not necessary to
lay out the entire length of the pipe.
Moscow No-Dig
The Russian Society for Trenchless Technology (RSTT) will be holding its biennial No-Dig event in 2012. The event will be
held from 5–8 June in Moscow.
The regional trenchless event is marketing for a broader audience and will focus on getting some out of region attendance.
The society said that it has a close co-operation with the German Society for Trenchless Technology’s (GSTT)
Dr Klaus Beyer regarding German attendance and will organise official German participation in the event.
At the time of publication the website for the event is still under construction, but make sure to keep an eye out on the

Reflections on
No-Dig in Hong Kong
CIPP project in Hong Kong.
by Ian Vickridge, Consultant, and previous Technical Director with
Black & Veatch Hong Kong and Past Chairman of the CHKSTT
The Trenchless Technology industry in Hong Kong has grown significantly as the urban terrain
challenges open-cut methods for major projects. Here, Past Chairman of the CHKSTT Ian Vickridge
reflects on the trenchless industry and how he has seen it evolve.
The opening ceremony of the CHKSTT conference
in Macau in 2007.
Swagelining in Hong Kong.
under Hong kong
October 2011 - Trenchless International
Ian Vickridge first became involved
with the development of Trenchless
Technology in Hong Kong in 1997, when
he presented a short course on Trenchless
Technology to a group of young Hong Kong
engineers. Among this group were several
enthusiasts who went on to champion
Trenchless Technology in Hong Kong, and
eventually helped to form the China Hong
Kong Society for Trenchless Technology
(CHKSTT).
In 1997, there were already some interesting
major trenchless
projects underway, including
some large diameter, deep
sewer construction by tunnel
boring machines (TBM)
for Stage 1 of the Harbour
Area Treatment Scheme
(HATS), and a long-distance
horizontal directional
drilling (HDD) project. The
HATS sewer construction
had run into problems that
were later resolved and
the project was eventually
completed in 2001. The
HDD project was record
breaking at the time, consisting of two large
diameter bores, each 1.4 km long, drilled
along difficult profiles through heavily faulted
granite, deep below a main shipping channel
and close to the new Tsing Ma suspension
bridge. The bridge had recently been completed,
connecting mainland Hong Kong
to the new international airport on Lantau
Island. However, although this project was
a major achievement attracting international
attention, the use of trenchless methods for
the installation and rehabilitation of urban
utility services was very limited, and most
work of this nature was still being carried
out by open-trench methods.
That being said, things were moving
on and by the end of 1999, the
HDD project was nearing completion.
A similar HDD project to install electricity
cables across the same Ma Wan
Channel was well underway, and a small
but dedicated group of individuals had
formed the CHKSTT to act as a forum
to encourage even
greater use of trenchless techniques.
Initially the new society organised local
technical talks and site visits, but they were
soon gaining further exposure to the latest
developments in Trenchless Technology
through dialogue with the ISTT and other
Affiliated Societies. In 2002, a delegation
from Hong Kong attended the No-Dig
CIPP project in Hong Kong.
International conference and exhibition in
Copenhagen, and this was followed by participation
in Trenchless Asia – a successful
conference and exhibition held in Hong
Kong in 2002.
By this time there was considerable
interest in trenchless methods, and it is
interesting to note that although many of the
papers presented at this conference were
from overseas, there were several local
papers describing the actual and planned
use of a variety of trenchless methods in
Hong Kong. This was largely influenced by
the program of water mains replacement
and rehabilitation that had been launched
by the Water Supplies Department (WSD)
of Hong Kong.
Trenchless makes its mark
By 2002, the use of trenchless methods
for urban utilities was really taking off and it
was not long before innovations were being
made and international records established
in Hong Kong. By 2004, a variety of rehabilitation
techniques, including close fit
PE linings, slip lining, cured-in-place
pipe (CIPP), and spiral-wound linings,
were being widely
used. Open trench
was no longer
the only method
being considered
for installing new
Swagelining project.
pipes and cables – HDD, pipe jacking, and
pipe ramming were all recognised as being
realistic, tried and tested alternatives.
The use of trenchless methods continued
to flourish, and at the same time a synergistic
interest in pipe condition assessment
started to grow. Soon, a variety of new
techniques for assessing pipe condition, by
both direct and indirect methods, were
being employed. These included historical
reviews of burst and leaks, non-destructive
methods for determining pipe
wall thickness, soil corrosivity studies, stray
current surveys, coating defect surveys, and
leak detection surveys. This interest in condition
assessment was evident in the
papers presented at the first international
conference organised by CHKSTT, which
was held in Macau in 2007.CHKSTT went
on to organise a subsequent conference in
Hong Kong in 2009 for their 10 th anniversary
year and are now in the process of organising
their 3 rd conference to be held in Hong
Kong later this year.

The people of the CHKSTT
One of the guests at the conference
in 2009 was Glenn Boyce, who was
instrumental in getting the CHKSTT going
and was their first Chairman. Glenn later
went on to become Chairman of the
North American Society (NASTT). At the
same conference Jon Boon took over
the Chairman’s job at CHKSTT from Ian
Vickridge – Jon had previously been
Chairman of the UK Society (UKSTT) and
Ian had previously been the Executive
Secretary for UKSTT.
Another strong international player in
the CHKSTT is Derek Choi, who is not
only a past Chairman of CHKSTT but
also a longstanding member of the ISTT
Executive Sub Committee and now Vice
Chairman of ISTT.
Although the CHKSTT is relatively small,
it has always had strong international
links with other Affiliated Societies and
the ISTT. It is these connections and the
international support provided by ISTT
and the family of trenchless societies that
have helped drive the advancement of
Trenchless Technology in Hong Kong over
the past decade or so.
Under Hong Kong
As one of the most densely populated
cities in the world, Hong Kong is a city
where trenchless techniques are not only
preferable in construction and maintenance,
but often essential.
With a total area of 1,104 square km and
a population of more than seven million
people, most of the land in Hong Kong is
occupied. When underground infrastructure
requires repairs or general maintenance,
simply digging to reach infrastructure is not
always an option.
Further complicating matters is the fact
that the majority of land is hilly to mountainous,
with steep slopes, making conventional
trenching techniques for laying and then maintaining
underground infrastructure difficult.
Sparking the trenchless boom
In 1998, Hong Kong’s WSD first used
Trenchless Technology on a large scale
water main installation program, sparking a
boom in no-dig techniques in Hong Kong.
The value of trenchless work in Hong Kong
started expanding from a previously low
base as business began to invest in trenchless
equipment and expertise.
Contracts for works relating to trenchless
technologies in Hong Kong were often
subcontracted as part of larger projects to
companies that specialised in the field of
trenchless methods. This was due to the
fact that only larger, government-approved
companies in Hong Kong could qualify
to bid for sizeable civil engineering contracts,
while companies that specialised in
Trenchless Technology – which tended to
be smaller, while the industry developed
– were left to bid on the individual works
involved with these projects.
When the industry in Hong Kong was
still small and developing, local contractors
partnered with overseas firms to gain
further expertise and a base with which to
tap the Hong Kong market. In particular,
German companies are well regarded both
in Hong Kong and worldwide for their reputation
for reliable technical support.
Germany’s Herrenknecht dominated the
microtunnelling market, spiral wound PVC was
well regarded for close fit lining, and German
products were often called on for pipe cleaning
equipment, relining and pipe bursting.
Giving new life to old water mains
Hong Kong’s fresh water and salt water
supplies are provided through a network
7,800 km of water mains, most of which are
underground. A substantial portion of these
water mains were laid over 30 years ago and
are now approaching the end of their service
life, becoming increasingly difficult and costly
to maintain.
As such, WSD is currently undertaking the
Mains Replacement and Rehabilitation program,
which will see approximately 3,000 km
of the water mains rehabilitated or replaced.
This massive 15-year phased project
started in 2000 and the estimated cost is
$HK22.8 billion ($US1.3 billion). Due to its
size, the project has been divided into sections
by region. The program is currently in
its final stage, which started in March 2011,
and approximately 53 per cent of overall
works were completed in June 2011. It is
estimated that 30 km of water mains are
replaced or rehabilitated monthly.
Important considerations for all sections
of the project include avoidance of
unnecessary water supply disruption to
consumers, avoidance of unnecessary traffic
disruption during construction and cost
effectiveness of the works, with priority to
be given to water mains susceptible to leakage
and bursting.
While conventional mains replacement
methods of opening trenches and laying
new mains continue to be used where the
CIPP project.
traffic and environmental impacts arising
from the works are not serious and when
the underground utilities present are not
congested, sections of the project require
the use of trenchless methods.
As these techniques have been employed
to avoid Hong Kong’s already congested
underground infrastructure network, the
replacement water mains have been laid
deep underground.
The main techniques the WSD has been
using for replacement of mains include pipe
ramming, pipe jacking and horizontal directional
drilling, while the main techniques to
be employed for rehabilitation will be the
close fit lining method, the cured-in-place
pipe method and the pipe bursting method.
The project is due for completion in 2015.
Breaking ground around town
In recent years, Hong Kong has
embraced the benefits of microtunnelling
for many of its infrastructure projects.
With the country’s dense urban landscape,
the use of microtunnelling has
vast benefits such as avoiding the disruption
and damage caused by excavation.
Pipelines can be installed using a remotely
controlled and steerable method, usually
with the use of a laser guidance system.
Microtunnelling is well suited to rigid line
and level criteria, which enables boring to
be undertaken at flatter grades.
Construction on the Drainage Services
Department of Hong Kong’s Tuen Mun
Western Trunk Sewerage Project is ongoing
since its commencement in 2009.
Chun Wo Development Holdings Limited
was contracted last year by the department
to use a TBM for pipe construction for more
than 4 km of the 6 km long trunk sewer.
The project, which also included a sewage
pumping station, is expected to be
completed in 2014.
Bringing industry
leaders together
China is one of the largest markets for Trenchless Technology, and it is currently gearing up for its
13 th International Conference on Pipelines and Trenchless Technology 2011, which will see over 1,000
visitors to its exhibition and 500 delegates to its technical program in its three-day conference held
from 26–29 October in Beijing, China.
At present, China is the largest market
for Trenchless Technology, with large gas
and oil transmission pipeline projects
under construction and 100,000 km of
municipal pipelines newly installed
each year. In addition, 300,000 km of
municipal pipelines need to be rehabilitated
urgently. There are more and more related
international organisations and companies
paying more attention to the pipeline and
Trenchless Technology market in China.
The US Joint Centre for Trenchless
Research and Development (CTRD),
American Society of Civil Engineers-
Pipeline Division (ASCE), Centre for
Underground Infrastructure Research and
Education (CUIRE)-UTA, Geo-Technical
Engineering Research Centre, China
Ministry of Education, and China University
of Geosciences (Beijing) will co-sponsor
the International Conference on Pipelines
and Trenchless Technology (ICPTT) 2011.
Trenchless International is also happy to
announce itself as a supporter of the event.
With the success of the ICPTT 2009,
the organiser expects that ICPTT 2011
will draw more than 500 participants, and
more than 1,000 visitors will attend the
conference.
This year, ISTT Chairman Dr Sam
Ariaratnam will be a VIP guest at the conference,
along with other great knowledgeable
academic and industry speakers.
The conference will have three streams for
the technical program – gas/oil pipelines and
storage, Trenchless Technology and rehabilitation,
and municipal infrastructure planning
assessment and design.
Venue
ICPTT will be held at the China National
Convention Centre (CNCC), which officially
opened in October 2009.
The Centre was an important element
in the overall plan for the 2008 Beijing
Olympic Games when it served as the main
press centre and international broadcasting
location. CNCC is ideally located in the
heart of the Olympic Green adjacent to the
National Stadium (Bird Nest), the National
Aquatics Centre (Water Cube) and the
National Indoor Stadium – all of which are
great places to go and see while in town
for the conference.
Don’t miss the ITTRC
The 13 th International Trenchless
Technology Research Colloquium (ITTRC) will
run in conjunction with ICPTT and will be held
from October 24–26 in Beijing, China.
Dr Baosong Ma from the China University
of Geosciences-Wuhan will be hosting the
ITTRC in Beijing immediately prior to the
ICPTT. Any university academic who submitted
a paper to the ICPTT conference
will be provided with complimentary registration
and accommodations. This offer is
extended only to the academic community
Still exhibition space left!
Do you currently work in China or do you
want to break into this rapidly growing market
Then ICPTT is an ideal event for you!
ICPTT will bring together the leaders
of pipeline and trenchless and is an ideal
exhibition to be at for companies wanting to
break into the industry.

Water and wastewater services are generally provided as a public service by a public utility owned by
local or national government. In some countries, including France, the UK and the Czech Republic, these
services are largely provided by private companies, while in other regions, such as Germany and the
United States, most utilities have a mix of private and public ownership. Here, Trenchless International
focuses on the water and wastewater utilities in the Asian region of Singapore, Hong Kong and Japan.
Singapore
In Singapore, the Public Utilities Board
(PUB) services the entire population of
4.8 million people.
PUB is Singapore’s national water and
wastewater utility and is a statutory board of
the Ministry of the Environment and Water
Resources.
PUB also oversees the NEWater system,
which converts used water into potable water.
The first NEWater plant was completed in
2000, and today there are four plants throughout
Singapore to supply 30 per cent of the
country’s drinking supply.
The board uses a number of trenchless
technologies, such as pipe bursting and
spiral-wound lining in sewer rehabilitation
work as they continue to maintain the 3,400
km of gravity sewers, 220 km of pumping
mains and 130 pumping installations of the
sewer reticulation system.
PUB has also used trenchless methods
to reline some 600 km of public sewers and
private drain lines under their sewer rehabilitation
program. Techniques used include
cure-in-place piping (CIPP), spiral-wound
lining and fold-and-form technology.
The ongoing sewer rehabilitation program,
in the current phase 2009–2014, will see the
refurbishment of more than 1,000 km of this
network. Much of this work will be undertaken
using microtunnelling.

Hong Kong
In Hong Kong, the Water Supplies
Department (WSD) is the sole water utility.
The WSD is responsible for collecting,
storing, purifying and distributing potable
water to consumers, and also provides
seawater for flushing toilets. It is the sole
water utility in Hong Kong, and serves 99.9
per cent of the national population of seven
million people.
In 2000, the department started the
15-year Mains Rehabilitation and
Replacement Program, which will see
approximately 3,000 km of water mains
rehabilitated or replaced.
A substantial portion of the mains were laid
more than 30 years ago and are approaching
the end of their service life, becoming
increasingly difficult and costly to maintain.
The project will be relying on the use
of trenchless methods such as pipe ramming,
pipe jacking, horizontal directional
drilling (HDD), close fit lining, CIPP and pipe
bursting.
Work is progressing at a rate of approximately
30 km of water mains being replaced
or rehabilitated every month.
The WSD predicts that by the end of
the works, the anticipated number of
pipe failures per year will be decreased
from 24,970, recorded in 2000, to 15,000
by 2015.

Japan
In Japan, most water utilities are small in
size and are established by municipalities on
a self-sufficient basis
Approximately 124 million people use tap
water in Japan, and most of the remaining
people use their own wells or unregulated
small-scale water supply services.
At the end of 2007, there were 16,978 water
supply systems in Japan. On top of that,
there were 102 bulk water supply businesses,
which provide treated water to
water supply businesses.
While water utilities serve the population
on a small scale based on municipalities,
the Ministry of Health, Labour and Welfare
(MHLW) is responsible for maintaining the
quality of drinking supply in Japan. Water
utilities must also follow the requirements
outlined in the Waterworks Act 1957.
MHLW gives a licence to water utilities
that service populations greater than
50,000. Smaller water utilities must obtain a
licence from prefectural governments.
The Japan Water Works Association
(JWWA), established in 1932, is responsible
for improving public health by enhancing
the development of water supply. The
association conducts research on water
supply management, conducts inspections
and quality certification of water supply
equipment and provides registration services
for quality management systems.
The total length of water mains in Japan
was 262,183 km in 1975. This figure grew
to 610,066 km in 2007.
After 1945, Japan experienced a boom
of underground infrastructure construction.
As Japanese cities have now had sewer
networks of lengths longer than 7,000 km in
place for over 50 years, renewal is essential.
The former Japan Society for Trenchless
Technology (JSTT) Executive Secretary
said, “In 2005, the sum total of construction
using the rehabilitation method was
380 km, and the grand total of pipes
renovated from 1996 to 2001 has reached
3,000 km.
“Utilising the trenchless technique minimises
the need for traffic control, since it
doesn’t require a large space to dig the
road,” he said.
In Japan, many trenchless techniques
are being developed and put into practice,
such as CIPP, relining, pipe-eating and pipebursting.
This tunnel’s a beauty
In the bustling metropolis of Singapore, the Beauty World Station and Tunnel
project is making excellent use of innovative tunnelling technology.
The $US224 million Beauty World
Station and Tunnel project includes the
design and construction of the Beauty
World Mass Rapid Transit (MRT) underground
station, as well as station entrances,
subway links, architectural finishes and
external landscaping. It also includes the
development of two underground 1.1 km
rail tunnels, two cross passages, and 135
m of cut and cover tunnels.
The station, located at Upper Bukit
Timah Road near Jurong Kechil, forms part
of the Land Transport Authority (LTA) of
Singapore’s strategic network expansion of
the underground metro system. It will also
double as a Civil Defence shelter.
McConnell Dowell South East Asia was
awarded the contract for the scope of
works in March 2009. It is the company’s
first major MRT contract with the Singapore
LTA.
In June, assembly of the two 700 tonne
tunnel boring machines (TBMs) that will create
the rail tunnels commenced.
The TBMs were manufactured and fully
assembled in the Herrenknecht workshops
in China for factory acceptance testing.
They were then broken down for transport
and shipped to Singapore for reassembly
on site.
On arrival on site, the two 6 m diameter
TBMs were lowered piece by piece into the
30 m deep launching shaft and then assembled
below ground.
The project was recognised in July at the
LTA’s Annual Safety Award Convention,
where McConnell Dowell took out the top
prize for their work on the project.
The design and construction contract for
the project, DTL2-C916, received the ‘LTA
Contractors Challenge Shield’ ASAC Award
2011.
The DTL2-C916 project team has come
from diverse backgrounds with a wide
range of underground, engineering and tunnelling
experience.
McConnell Dowell also received a Safety
and Health Award Recognition for Projects
from the Workplace Safety and Health
Council of Singapore for performance
safety.
The award recognises projects or worksites
with excellent safety and health
performance and workplace safety and
health management systems.
Back on site at the Beauty World Station
and Tunnel project, construction is continuing
and works are scheduled for completion
in July 2015.

On the wastewater fast track
The first of three Robbins tunnel boring machines has been launched in Mexico City for work on
a 62 km long wastewater line, to be constructed as part of the Emisor Oriente project.
Commissioning of the 8.93 m diameter
tunnel boring machine (TBM) was
fast-tracked for work on Lot 1 after flooding
problems delayed another machine by six
months.
Three Robbins TBMs and three
Herrenknecht TBMs are planned for the
massive wastewater line.
Lot 1 contractor Ingenieros Civiles
Asociados Site Manager David Juarez said
in order to compensate for time lost due
to flooding, boring began with the Robbins
machine at shaft 5 of Lot 1.
The Lot 1 site, located in the Ecatepec
area outside of downtown Mexico City, has
seen widespread flooding during each rainy
season.
The Gran Canal, an open sewer commissioned
in 1910, is the area’s main sewer line
and floods its banks regularly, causing road
closures and significant health problems to
those living nearby.
The Robbins EPB at Lot 1 began boring on 13 July 2011 using an abbreviated start-up configuration
and umbilical cables connected to the surface.
The Emisor Oriente project
is designed to prevent
flooding and increase the
city’s wastewater capacity
by approximately 150 cubic
metres of water per second.
Due to a loss of slope because of the
city’s sinking lake clays, the canal now has
a positive vertical alignment below Mexico
City – the portion of the canal outside the
city has not been affected.
Increased volumes of water have the
potential to overload current pumping stations
and send the untreated water back
into the city.
The Emisor Oriente project is designed
to prevent flooding and increase the city’s
wastewater capacity by approximately 150
cubic metres of water per second.
National Water Commission’s
(CONAGUA) General Supply Coordinator
for Potable Water Miguel Guevara said
a treatment plant and a pumping station
was currently being built to pump the
water diverted into Emisor Oriente back
into the Gran Canal where the slope has
not been affected.
The Robbins TBM has started excavation
at Lot 1, using umbilical cables connected
to the surface and a sludge pump for muck
removal.
Once it has bored 150 m, a Robbins
continuous conveyor system and vertical
belt will be installed for the remainder of the
drive in mainly lake clays and sand.
Once the machine reaches the end of its
5 km drive to shaft 3A at Lot 1, it will be
removed and readied for its original 8.6 km
long bore at Lot 5.
Two more Robbins EPBs are scheduled
for launch later in 2011 – 9.2 km and
10.2 km bores at Lots 3 and 4 respectively.
It will operate in parallel with the city’s
other main wastewater line, Emisor Central.
Since the central line was built in 1964,
Mexico City’s population has more than
doubled, straining the system’s capacity.
CONAGUA has said it hopes the Emisor
Oriente will ease many of the city’s wastewater
problems when opened.
“We are working hard on pieces of the
problem, but the problem is not solved yet,”
Mr Guevara said.
The project is due for completion in 2014.
Components for the 8.93 m Robbins EPB, including the cutterhead, were lowered down the 45 m
deep shaft 5 for assembly prior to launch.
The commissioning of the first of three Robbins EPBs was fast-tracked at Lot 1 of Mexico City’s
Emisor Oriente Wastewater Tunnel.

Pipe pulling.
Powering the west coast
The Vancouver City Central Transmission Project, located in Vancouver British Columbia, Canada, is the
most significant upgrade by BC Hydro to the city's electricity system in 30 years. The project consists
of 8 km of 230 kV underground transmission circuits, including an 850 m horizontal directional drilled
crossing beneath the bed of False Creek and a new distribution substation with an ultimate capacity of
400 MVA, commissioned to an initial capacity of 134 MVA.
The $CDN200 million ($US210 million)
Vancouver City Central Transmission
(VCCT) project will be installing the new
electricity system under False Creek, from
David Lam Park in the Yaletown neighbourhood
of Vancouver to Laurel Street and
West 7th Avenue in the Fairview Slopes
neighbourhood of Vancouver.
The crossing
Michels Canada Co was contracted by
BC Hydro for the horizontal directional drilling
(HDD) crossing, among other trenchless
works on the project. Michels constructed
the HDD crossing with a minimum diameter
of 44 inches, within which was pulled a
34 inch conduit bundle consisting of 7x10
inch, 5x4 inch and 1x5 inch HDPE conduits.
In addition to this, Michels also had to
grout the annular space between the borehole
walls and the bundle, displacing the
drill mud using the 4 and 5 inch conduit
as grout pipes. Once complete, Michels
also constructed a transition on either end
of the crossing and HDPE to PVC duct
system terminating in cable vaults installed
by others.
Michels also was contracted to construct
some minor electrical works and restore all
worksites to their pre-existing conditions.
Why Trenchless Technology
Trenchless Technology was employed for
the VCCT project for a number of reasons,
including the minimal environmental and
public impacts of constructing the crossing,
and to minimise the duration of the construction
impacts.
VCCT Project Manager Marcel Reghelini
said, “Current engineering standards require
that the new power line remain serviceable
following a design earthquake event. The
depth of installation required to meet this
serviceability requirement was such that
installation by dredging would not have
been a practical proposition. The installation
would therefore be possible only with a
trenchless method.”
HDD was chosen as the preferred method
after considering both conventional tunnelling
and HDD.
“After analysis, it was concluded that the
design of cables with post-seismic stability
was significantly more complicated and construction
more expensive for cables installed
inside tunnels than for cables inside HDPE
conduit pipes installed in a HDD bored hole.
Also, both the cost and schedule duration
of tunnel construction was significantly more
than to complete a HDD bore,” said Mr
Reghelini.
Challenges
A number of challenges were overcome
during the HDD crossing, especially as work
was carried out close to the environmentallysensitive
water body of False Creek. Part of
the HDD bore path traversed through glacial
till soils that contained gravels, cobbles
and boulders. There was limited previous
experience of extensive drilling through
such material, except for an exploratory
boring carried out approximately two years
ago by BC Hydro.
Some length of the hole, drilled during the
exploration, was used in the final product
hole, but some new length of the hole was
also drilled through till.
During drilling, a number of underground
utilities that were not known about
at the design stage were encountered.
The construction plan had to be amended
to address problems presented by these
utilities.
The design required that a minimum of
90 per cent of the drilling fluid volume in the
annulus between the bored hole and the
bundle be replaced by a purpose designed,
low thermal resistivity grout. At its deepest
point, the HDD bore path was approximately
40 m below the bed of False Creek.
Tom Bryski of Golder Associates Ltd
(Project Geotechnical Engineer) said, “To
our knowledge, nothing like this scale
had been tried anywhere in the world
before. There were a number of challenges
in designing the grout that had to possess
suitable flowability characteristics to
traverse the 425 m distance to the lowest
point of the HDD borehole, and adequate
density to replace the drilling fluid by tremie
method and an elevation difference of some
50 to 60 m.
“At the same time the grout also had
to comply with the thermal resistivity
The pipe pulling along the street.
HDD at David Lam Park in June.
requirements established to ensure adequate
heat dissipation to maintain the
transmission cable design performance.”
The installation of the grout, 50 to 60 m
below ground level, and simultaneous
replacement of the drilling fluid presented
further challenges.
In addition, the work was carried out in
city streets in a very dense urban area, under
high public visibility and with lots of vehicle,
bicycle and pedestrian traffic. The pipe bundle
pull route was also along ten city blocks
and with two 90 degree bends.
As crews began to pull the pipe bundle
into the crossing under False Creek, the
bundle started to twist, and progress was
stopped one-third of the way into the bore
hole.
“Crews had to remove the temporary
bindings, untwist the pipe bundle using
fork lifts and excavators, and lay the pipes
directly onto the street to prevent further
twisting,” Mr Reghelini said.
Careful design and planning
To overcome these challenges, BC Hydro
used careful design and planning to ensure
the successful completion of the crossing.
“Readiness to change the construction
strategy when problems occurred – for
example, when unexpected utilities were
encountered and it was evident that if the
boring had continued as originally planned,
frac-outs could be a serious problem, it
was decided to use a pilot hole drilling
intercept method to overcome the potential
problem. A conductor casing was also
installed at the exit end,” Mr Reghelini said.
The project also conducted an extensive
construction communications program.
The project team kept the public regularly
informed regarding the construction, and
used various methods including:
• 24 hour construction phone line during
eight day pipe bundle pull and installation
• Local neighbourhood advisory group
meetings
• Hand delivered notices (sometimes on a
daily basis)
• Email updates (sometimes on a daily
basis)
• Website updates.
The team also used ‘silent’ equipment, in
that the equipment used was as silent as
possible and sound curtains were employed
where practical to mitigate noise.
Mr Reghelini also said that the great
teamwork involved also helped to overcome
some of these challenges. “The project
team – owner, contractor and consulting
engineer – worked collaboratively through
the project. When construction challenges
occurred, the focus of the discussion
amongst the project team was always in
solving the problem.”
Environmental and cultural
considerations
The HDD entry-pit was located in David
Lam Park adjacent to False Creek, a high
public-use area located near condominium
towers, a school and a day-care centre. The
area was identified as an area with a potentially
high risk of encountering contaminated
soil and water.
An Environmental Protection Plan was
required of Michels Canada to prevent
release of sediment into nearby catch
basins and drains which outfall to False
Creek, and to prevent and address inadvertent
spills of substances used during
construction like fuel, hydraulic fluid and
drill mud. Measures were required for the
proper disposal and treatment of any contaminated
water or soil encountered during
the course of construction.
The HDD entry and exit points were located
within fills overlying the historical shoreline of
False Creek. The historical shoreline of False
Creek has some known archaeological sites
associated with former settlements of First
Nation communities.

Curing the world
one main at a time
Cured-in-place pipe has had a revolutionising effect on the world of infrastructure
and asset management. Here, Trenchless International looks at some recent
projects implementing the technique around the world.
Per Aarsleff conducting CIPP work.
Australia
In June 2010, Kembla Watertech
successfully rehabilitated 1.8 km of a
600 mm diameter sewer trunk main in
Glenrock State Conservation National
Park, New South Wales.
The Dudley Charlestown system
transports wastewater from the Dudley
Charlestown catchment to the Burwood
Beach Wastewater Treatment Plant.
This trunk main was part of the Hunter
Water upgrade management plan
for the Dudley Charlestown upgrade
project, which involved abandoning the
Kahibah 1 wastewater pump station.
During the course of the rehabilitation
works, Kembla was involved in
14 separate Enviroliner air inversions
of various lengths. The longest inversion
length was 210 m through four
maintenance holes along the Yuelarbah
Management trail.
The company used techniques such
as Enviroliner pressure grade CIPP, for
the lining of the 1,800 m existing gravity
main, including a 110 m long aqueduct.

According to industry legend, agricultural engineer Eric Wood was repairing a corrosion hole in an air duct on a mushroom farm
when he conceived the concept behind cured-in-place pipe (CIPP) – the use of fluid pressure to press the repair medium against the pipe
wall while it cured in place to form a new pipe.
Supported by entrepreneurs Doug Chick and Brain Chandler, Mr Wood took the concept and sourced materials from resin producer Scott
Bader and felt maker WE Rawson – establishing the company now known as Insituform.
CIPP is now used all over the world.
Spain
Insituform used CIPP to complete a
pressure capacity upgrade for a primary
sewage force main in the coastal town of
Garrucha, located in Spain, in December
2010.
The sewer main carries roughly
80 per cent of the town’s sewage flow.
The population of Garrucha increases
by almost 60 per cent each summer,
straining the community’s water and
wastewater infrastructure.
To deal with this influx, an upgrade
to a nearby pump station provided an
opportunity to renovate the original
pipe with CIPP.
The original pipe was designed in the
1980s to operate at 2 bar; two completely
brand new pumps meant the
force main pressure would increase from
2 bar to 4 bar.
This project is the first-ever European
installation of Insituform’s InsituMain
System.
Canada
In December 2010, four ageing culverts running underneath a highway in Boisbriand,
Quebec, was upgraded using the CIPP process.
The corrugated metal stormwater culverts were severely deteriorated and in need of
intensive repairs.
The four culverts consisted of two 36 inch culverts at a length of over 160 ft, and two
48 inch culverts running 260 ft each.
Each installation was achieved using an air-inversion, steam-cure process that cuts
down on the amount of energy and water needed on the installation job site.
United States
In the second half of 2010, the City of Decatur, located in Illinois, selected CIPP to
rehabilitate three water mains in order to prevent disruption to its historic streets.
Water main breaks had caused temporary road elevation due to flooding, subsequent
depression and warping of the original brick pavement on historic Macon Street
near the Millikin University campus.
In a historic area, the road had to be preserved or repaired to its original state while
undergoing necessary repairs and rehabilitation.
Over 600 ft of the original 12 inch cast iron water main, installed in the 1940s, was
renewed using a fiber-reinforced CIPP.
In one day, the 600 ft section of CIPP was inserted into the host pipe using a water
inversion process and cured using hot water.
Hong Kong
In August 2010, Insituform
Technologies started CIPP work on a
$US17 million project for the Drainage
Services Department, Hong Kong
Special Administrative Region.
Insituform was recently awarded
two term contract renewals, which
provide for the rehabilitation of wastewater
pipelines located throughout the
highly populated Central District and
Mainland North District for three and
five years respectively.
The 4–84 inch diameter circular and
box shape pipelines were constructed
of clay, concrete or brick.
Some of these pipelines dated back
to the colonial years of Hong Kong.

CIPP relining in 22 days
Sewers of various lengths and diameters, across nearly 50 locations in Essex, located in the UK,
received a swift rejuvenation by Aarsleff Pipe Technologies.
Curing the Kingdom
The first trenchless specialised local contractor in Saudi Arabia,
International Aramoon Corp, recently completed a rehabilitation
project for the Water Authority of Eastern Province.
cipp
October 2011 - Trenchless International
The company successfully relined
2.8 km of wastewater networks as part
of Anglian Water’s Basildon and Billericay
Sewer Rehabilitation scheme.
The sewers were renewed with Per
Aarsleff’s cured-in-place pipe (CIPP), with
resin-impregnated polyester felt liners,
which formed internal joint-free, leakproof
smooth bore pipes. Per Aarsleff (UK)
worked with framework contractor Barhale
Construction plc as part of the One Alliance
delivery partnership for Anglian Water.
One of Aarsleff’s installation teams came
from Denmark for the Basildon project and
averaged 2.75 liners a day, beating the
client’s production requirements of two liners
a day by 40 per cent, and on one day
installed four liners.
The required 46 liners ranged from
150 mm to 450 mm in diameter and from
15 m to 136 m in length.
Per Aarsleff completed the lining in two
visits with an interval of two weeks.
Before any lining took place, JK
Environmental was employed to perform
detailed inspections using CCTV and initial
cleaning to determine a program of renovation.
In addition its purpose built installation
and steam curing equipment was tested
and approved for working to UK health and
safety requirements.
Barhale Contracts Manger Richard
Beecroft said, “Aarsleff is a very experienced
outfit and has worked extensively
throughout Europe, but had to adapt to UK
requirements and legislation, which they did
quite well.”
Typically at each installation, a thin
plastic pre-liner, with a blanked end, was
first inserted into the damaged pipeline
using compressed air to protect the main
resin-impregnated polyester liner during
installation.
The main liner, manufactured by Aarsleff
was made inside out from special resinimpregnated
needle felt, so that the outside
surface eventually became the inner smooth
bore surface when the liner was inverted
into the damaged pipeline.
The main liner was packed in flake ice
during delivery from the factory to site to
prevent premature curing.
The liner was wound into the special
inversion drum, inside a purpose-built lorry
incorporating all the necessary equipment
Aarsleff installed 46 CIPP resin impregnated polyester felt liners of 150–450 mm diameter and
lengths of 15–136 m at an average rate of 2.75 per day.
One of Aarsleff’s installation teams came from Denmark for
the Basildon project and averaged 2.75 liners a day, beating
the client’s production requirements of two liners a day by
40 per cent, and on one day installed four liners.
for the lining installation process. A length of
liner was pulled out of the drum and turned
back on itself so the inside of the liner was
now on the outside.
The liner was pushed onto the outlet nozzle
of the inversion drum and held in place
with special clamping bands. It was then
lowered down into the manhole and guided
by hand a short distance into the pre-liner
and into the entrance of the pipeline.
The inversion drum was then pressurised
with compressed air, which forced the liner,
with its closed end, to unwind from the
drum and unfold and invert itself through
and out of the open end of the damaged
pipeline. The inversion process forced the
liner through the pre-lined damaged pipe
and against the wall, which effectively acted
as a former for the new lining.
A steam pressure hose was then connected
from a special boiler inside the lorry to
the inversion drum to heat up the liner.
At the same time a steam exhaust pipe
was also inserted into the exposed section
of liner protruding from the exit manhole.
Temperature probes were attached to the
liner, which was gradually heated by the
steam to 110°C, and depending on the
pipe diameter, held for specific periods to
cure the resin-impregnated liner.
The entire liner inversion and curing
process was controlled and monitored by
a computer on board the self-contained
lorry.
The lorry is fitted with highly advanced,
purpose-built installation equipment,
including the boiler and compressors,
needed to perform the No-Dig, CIPP
process.
After curing and cooling, the ends of the
new liner, which formed a self-supporting
pipe within a pipe, were cut off.
The Kingdom of Saudi Arabia’s Eastern
Province water authority was faced with
severe problems in its 600–700 mm gravity
sewers.
International Aramoon Corp (IAC) was
approached to discuss the project and
perform an inspection and condition
assessment for the gravity sewers, as well
as provide services for pipeline rehabilitation
works.
The 2.3 km pipeline was made from ductile
iron and located at an average depth
of 4 m below the ground in Dammam City.
Extensive cleaning had been completed
to facilitate the CCTV robotic inspection and
several problems were identified from the
pipeline surveys. These included infiltration,
wall encrustations, partial blockages and
severe corrosion.
After evaluating the situation, IAC recommended
the use of the cured-in-place pipe
(CIPP) UV system for the gravity sewer
pipelines in order to restore 100 per cent
hydraulic efficiency and structural strength
of the pipelines.
BKP Berolina-Liner System, the CIPP-UV
system supplier of equipment, liners and
training, had made the structural calculation
and liner design based on the information
provided by IAC.
During the preparation and installation of
CIPP-UV system, IAC paid special attention
to safety precautions, especially when
rehabilitating sewer infrastructure in heavy
traffic areas.
The CIPP-UV system is designed for
fast and efficient onsite installation that
minimises the economic, social and environmental
impacts.
As demand in the region increases, IAC
has said the company is well prepared to
meet them and undertake No-Dig works for
the wastewater network in Saudi Arabia.

CIPP
October 2011 - Trenchless International
Since its market launch in Germany in 2008, the SPR method has enabled defective sewer lines to be
rehabilitated with a spiral-wound pipe liner formed of endless steel-reinforced PVC profile strips inside
the sewer. The current rehabilitation of the Uchte canal in Stendal, located in Germany, by specialists
from the Brehna office of KMG Pipe Technologies GmbH shows that even exotic profiles with large
nominal diameters can be rehabilitated by this method.
Historic structure in Stendal
The Uchte canal is one of the oldest parts
of Stendal’s subterranean infrastructure.
As early as 1887, the River Uchte, which
used to flow openly through the Stendal
town centre, was ‘tamed’ by turning the
water course into a canal. For this purpose
a dome profile sewer, with a crown height
of 1.74 m and bottom width of 1.5 m,
was built in the present-day alignment of
Bruchstrasse.
The sewer was constructed in tamped
concrete on a brick foundation – a technology
applied to many structures at that time.
However, after 130 years of continuous use,
these structures are fraught with the same
problems. The integrity of the concrete is
weakened, the walls are becoming porous
and no longer watertight, their surface
is disintegrating and they are becoming
unstable.
Unusual structural design
Due to the traffic load, and a minimum
coverage of only 15 cm in some places,
it was threatened with imminent collapse.
Immediate action was called for; especially
because Bruchstrasse is a main street in
Stendal’s town centre.
Having recognised this danger, the
owners of the Uchte canal instructed
Magdeburg-based engineering office
MUTING GmbH to prepare a rehabilitation
concept. An open-cut method to renew
the old structure was quickly excluded, as
it would have been highly labour intensive
and costly due to the unstable subsurface
conditions and constant high groundwater
table.
Furthermore, reconstruction would have
taken much longer – an impossible scenario
in the centre of Stendal’s business
district, particularly since Bruchstrasse is
currently undergoing a full facelift as part
of the town centre redevelopment. In addition,
Bruchstrasse is immediately adjacent
to Marienkirche and crosses a century-old
burial ground, making it an archaeologically
sensitive site.
Trenchless solution called for
A key consideration in opting for the
trenchless rehabilitation method was the
reliable restoration of the necessary stability
of the old structure. After a careful technical
analysis the authorities decided to use the
SPR spiral-wound pipe lining method over
short pipe relining.
This option was offered by the Brehna
branch of KMG Pipe Technologies GmbH,
a subsidiary of Sekisui SPR, Schieder-
Schwalenberg. The deciding factor in
Stendal was that the spiral-wound pipe
lining could be installed using the existing
manholes – without the excavations usually
needed for laying short pipes. The road
resurfacing work was able to be performed
parallel to the sewer rehabilitation because
of trenchless installation.
Description of the procedure
The SPR method is a cutting-edge version
of spiral-wound pipe lining technology.
The basic principle of SPR spiral-wound
pipe rehabilitation is that the decayed
sewer section is repaired using an endless
PVC-U or HDPE profile strip (spiral-wound
pipe).
The endless profile strip, wound on a
drum, is fed into the sewer through an
open manhole and joined by a spiral-winding
machine installed in the sewer to form
a pipe by a tongue and groove technique.
Liners of practically any length can be
created: as soon as one of the aboveground
profile drums is empty, a new coil
is joined onto it by the heated tool butt
welding method. Apart from this short
interruption, the SPR method permits continuous
working.
Flexibility as a guarantee for
success
A major advantage of the spiral-winding
method is its extreme flexibility in irregular
cross-sections, and furthermore open cut
construction can be avoided. The SPR
spiral-wound method can be used on special
profiles of every conceivable type and
dimension up to DN 5,000 mm, as well as
the standard-sized circular and egg-shaped
profiles.
For a new situation, as was the case
with the special dome profile of the Uchte
canal, the winding frame only needed to be
adjusted to the dimensions and cross-section
of the structure being rehabilitated. This
sewer data had been precisely determined
in the structure beforehand using a 3D laser
scan to ensure unhindered passage of the
spiral-winding machine.
The special feature of SPR technology is
the unique winding frame crawls along the
full length of the structure, forming the spiral-wound
pipe from the profile strips trailing
behind it. The machine does not remain in
the starting shaft, pushing the spiral-wound
material into the sewer ahead of it.
Being waterproof and stable are not
the only structural benefits of the spiralwound
liner as a rehabilitation system.
The spiral-winding process intentionally
leaves a defined annular space between
the SPR liner and the old pipe, into which
a high-strength mortar is injected in a subsequent
work stage. In addition, the annular
space is walled off and cells filled at regular
intervals.
Ultimately, the SPR liner serves only as
formwork for a new concrete inner shell of
the old sewer, and long-term it provides a
reliable protective layer to shield the concrete
structure from the effects of sewage
and sewer atmosphere. Logically, the annular
space is not minimised at the planning
stage, but consciously defined according to
static requirements.
The dimensions of the SPR liner are
measured in ‘as much annular space as
(statically) required’ and not ‘as little annular
space as possible’. Whether the resulting
reduced cross-section is acceptable
compared to the old pipe is a question of
the hydraulic analysis necessary for each
individual case in the course of planning.
The reduction in diameter is already partially
compensated for with the extremely good
friction co-efficients of the new, smooth
SPR liner.
Intakes open during winding
Several feed conduits enter the canal in
the course of the section to be rehabilitated
– these had to be reconnected after rehabilitation
work. For this purpose the liner
was opened at the precisely measured and
colour-marked position of the conduits,
and a PVC pipe of the appropriate diameter
inserted into the intake. Spiral-winding
technology enables the inflow from the
feed conduit to be maintained.
The entry points were closed off with
deep plugs, which were removed after the
sealant had hardened, to prevent material
from obstructing the junctions when the
annular space was subsequently sealed. In
a final stage the intake pipes were milled off
flush and cleanly connected by GRP hand
laminate to the inside wall of the new sewer.
Second generation material
In view of the obvious advantages of
the system, municipal network operators
have overcome their historic reservations
in respect of the material PVC – particularly
pleasing from the point of view of KMG Pipe
Technologies.
In recent years, the nationwide bans,
some of them instigated in the 1970s, have
been lifted following an updated ecological
evaluation of the material, giving further rise
to confidence that the certified SPR spiralwound
pipe lining method will consolidate its
position in the sewer rehabilitation market in
the near future.
At an open viewing of the construction
site in Stendal’s Bruchstrasse, held from
17–19 May 2011, sewage experts from
authorities and water boards including Kiel,
Magdeburg and Erfurt were able to inform
themselves of the possible uses of the SPR
method in difficult situations.
Among them were employees of the
Berlin water utilities responsible for sewer
rehabilitation. All of them took a critical look
at the spiral-wound dome profile liner below
ground. The project was completed successfully.

Largest to date:
relining in France
Near the city of Lille, located in the north of France, 4 km of sewer
drains were rehabilitated using UV-light curing pipe liners from DN
600–1,200 mm made by Reline Europe – an unprecedented project
in France.
The project was for the municipal client,
Lille Métropole Communauté Urbaine (LMCU),
who saw the benefits of using Trenchless
Technology for its sewer rehabilitation with the
Alphaliners from Reline Europe.
Until recently, the GFRP lining system
and the UV technology were unknown to
LMCU, and while sceptical at the beginning,
the record of previous installation results
and successfully implemented projects convinced
the client.
The job was awarded to sewage system
specialist AXEO Brumath, France, and had
to be completed within a short time frame
of only a few months – between March and
July 2011.
In Emmerin, near Lille in northern France,
the main intercepting sewer leading to a
wastewater treatment plant had become
derelict. The sewage system, which had
been built in the 1970’s was showing major
signs of damage.
Although there was nothing wrong with the
statics of the old pipes; excessive corrosion,
displaced pipe couplings and penetrating
roots were causing leaks, and up to 90 per
cent of the pipe system was overgrown. The
rehabilitation was essential.
With an overall pipeline length of 4 km
and pipe diameters of up to DN 1,200 mm,
the rehabilitation project was a demanding
project that had to be completed within a
very tight time frame. The sewage system
runs along a nature reserve which will likely
be restructured in mid 2011.
Construction Supervisor at AXEO
Brumath Michel Moller said, “This is the
largest project of this kind in France to date.
Considering the length, diameters and
short completion time, the entire French
rehabilitation industry is considering this
task as a reference project.”
The narrow time frame as a
challenge
The challenge for the professionals at
AXEO Brumath was to complete the project,
including all preparation and finishing work
within the narrow time frame. The pipes
affected were two main intercepting sewers.
The first, with a length of 1,255 m and
a diameter of DN 1,000 mm, runs from the
pumping station at the nearby industrial area
and the Port Santes along the nature reserve
‘Le Parc de la Deûle’ to the wastewater treatment
plant.
The second intercepting sewer – diameter
DN 1,200 and 3,009 m in length
– connects the commune Wattignies with
the wastewater treatment plant. A 243 m
feed pipe with a diameter of DN 600 mm
leading to this main intercepting sewer had
already been rehabilitated.
The initial phase involved restoring the
segment from the pumping station to the
wastewater treatment plant. This required
Monitoring the curing process.
the installation of a 1.4 km long water bypass
system through which the water could
flow from the industrial area to the plant
during the construction phase.
Mr Moller said, “Designing the water
drainage bypass as a single, large system
makes sense. It enables us to perform work
along the entire construction site efficiently
without any major loss of time caused by
things like daily sewer cleaning.
“In this first segment, DN 1,000 mm
Alphaliners, with a wall thickness of
7.2 mm, were installed over a length of
1,255 m. The logistics on their own in this
respect were immense. The total weight of
all installed liners amounts to approximately
236.5 tonnes. Reline Europe supplied the
liners in the lengths required for the respective
installation segments. The Alphaliners
were then pulled into the sewer directly from
the lorry with the help of a conveyor.”
Also on site was David Veltz from Reline
Europe who had already co-operated
closely with AXEO Brumath during the
preparation phase. “Obviously, entering
the French market with such a large
project is a challenge for us. But we
all acted in concert, from the production
employees to the management. That
the project was a success is due to the
good co-operation between the city of
Lille, AXEO Brumath and Reline Europe,”
Mr Moller said.
Pulling the liner DN 1,000 mm into the sewer pipe with a conveyor.
Fast curing – short installation time
Once completed, work on the approximately
3 km long intercepting sewer was
carried out. Again, the construction vehicles
were only able to drive to the drainage system
on specially built construction roads.
Thanks to the clever choice of the installation
segments and the deployment of two
construction crews at the same time, the
construction team was able to complete the
construction work even faster than originally
planned. Up to five liners were installed per
week.
The company opted for various logistical
solutions to implement the liner order. The
Alphaliners DN 1,000 mm, for example,
were delivered in individual boxes. The
larger DN 1,200 mm Alphaliners, however,
were delivered in overseas containers.
“With this method, we are much more
flexible and also more environmentally
friendly, since we do not use disposable
packaging. We are thus also able to deliver
very heavy liners reliably to the construction
site,” said Mr Veltz.
On site, the large-dimensioned liners
were pulled into the sewer system with
a cable winch. By using a 1.5 km long
winch cable, the set-up time between the
individual installation segments could be
kept to a minimum. Once the liners were
inflated, UV light was used for the curing
process at a speed of approximately
40 cm per minute. To achieve this, a light
train of nine UV lamps, with a capacity of
1,000 watts each, was moved along the
installed liner.
Even with longer installation sections,
the curing process only took a few hours.
Due to the well-structured work and fast
processing method, up to 150 m of sewer
pipes could be rehabilitated on an average
Conclusion
As well as saving time and protecting the
environment, trenchless sewer rehabilitation
with UV light curing GRP liners has another
advantage.
“After 30 years of experience in sewer
rehabilitation using hot water as the curing
medium, I am now able to compare the two
methods. In addition to the advantages for
the environment, the UV system also has
benefits for the residents. While hot water
curing requires the construction site to be
manned day and night, this method allows
interruptions and can be continued the following
day,” said Mr Moller
In his opinion, the system used in Lille is
currently the best sewer rehabilitation system
available.
The Alphaliner method from
Reline Europe was recently
certified in France by the
Scientific Centre of Technology
and Construction, France
(CSTB).
The new pipe liner generation
The new Alphaliners feature special advantages in design and
material composition compared to traditional liner technologies.
An additional benefit is the specially adapted UV curing technology
for an optimal and durable quality of the final product, which
allows a service life of at least 50 years.
RELINEEUROPE also offers the complete equipment as well as
technical service and support around the world.
Rely on liner technology of the latest generation.

Modernising London
Thames Water is replacing 100-year-old leaking water pipes in Catford, United Kingdom,
by using pipe bursting.
More than two miles of old cast-iron
pipes, which were laid more than a century
ago, will be replaced with new hard-wearing
modern pipes less prone to bursts and leaks.
The £2.5 million project started in July
and will take seven months to complete.
Most of the work will be done in Rushey
Green and Bromley Road.
The project is part of a London-wide
scheme to improve the capital’s pipes.
Head of Capital Delivery Lawrence
Gosden said, “This is an essential project
and one that will benefit people in Catford
and the surrounding area for decades to
come.”
“While we apologise for the inevitable
disruption work of this nature causes,
replacing old and leaking mains is essential
as our water resources come under
increasing pressure from climate change
and population growth.
“Ideally we wouldn’t have to do this work
at all, but the fact is London’s water pipes
are old and leaky and need replacing. We
are doing everything we can to keep disruption
to a minimum.”
In the past five years, Thames Water has
installed 1,300 miles of new pipe, cutting
leakage by 27 per cent.
More than 20 per cent London’s water
mains are over 150 years old – the oldest
in the UK – and more than 40 per cent are
over 100 years old.

A rope and a Cobra
A multi-million dollar water mains rehabilitation project for Northern Ireland Water prompted a pipe
bursting demonstration with the use of a rope-pulling mechanism from ABS Trenchless GmbH, on a
6 inch spun iron pipe section.
In 2010, Northern Ireland Water awarded Farrans the five-year
rehabilitation project for £50 million.
Northern Ireland’s current water main infrastructure supplies
approximately 625 million litres of water per day to 1.7 million people.
Some of these mains are more than 40 years old and are now
prone to bursts, leaks and pressure problems.
To minimise disruption, pipe bursting was chosen to reduce time,
resources and space by breaking up the existing water main and
pulling through new pipes with no need excavate.
In June, ABS Trenchless GmbH (ABS) carried out a
demonstration of the company’s RBS 450 rope bursting system
in County Armagh. The demonstration involved replacing
the existing 6 inch spun iron pipe with 225 mm diameter
HDPE pipe.
A 200 m long section of works was identified, which included a 20
degree bend, as an appropriate section to demonstrate the pulling
capability of the system and its ability to negotiate various deviations
in line or level.
The Rope Bursting System Range includes 40, 50,
80, 120, 150 and 190 tonne versions. For more

Pre-bursting operations
A 3 x 1.5 m bursting pit was excavated down to the invert of the
existing pipe with the old pipe removed from the trench.
A rigid plastic line, locally called a ‘Cobra’, was pushed through
from the starter pit, located 200 m from the bursting pit. The Cobra
was then attached with an auxiliary rope and was pulled back to
the starter pit.
The RBS 450 was lowered into the bursting pit. The hydraulic
hoses were then connected to the powerpack, and the wire rope
from the winch fed through the unit. The wire rope was connected
to the auxiliary rope and the small petrol driven winch pulled back
the wire rope to the starter pit.
Once the auxiliary rope and wire rope were pulled back to the
starter pit, the ropes were disconnected and the wire rope connected
to the bursting assembly as shown.
Following the connection between the wire rope to the bursting
assembly, the rope bursting process commenced. Along the route,
a pit had been excavated at 55 m for a connection to an adjacent
road. This offered a chance to see the assembly bursting through
the ground.
The operation of the RBS 450 unit took place remotely from an
adjacent low wheel base trailer that accommodated the winch,
remote control module and the powerpack. This arrangement was
advantageous as it reduced mobilisation and de-mobilisation times.
The bursting process took three hours and ten minutes to pull
200 m of 225 mm diameter pipe. The bursting assembly was then
removed from the bursting pit and disassembled in preparation for
de-mobilisation from site.

Bursting for a new look
A total of 15 pipe bursting runs will be completed as part of the Inwood-Dellwood-Bellaire sewer
rehabilitation project, located in Ohio, United States, by Avon Lake Municipal Utilities.

October 2011 - Trenchless International
The project aims to relieve some of
the sewer surcharging on Redwood, near
Avon Belden, and on Lake Road, along
with infiltration problems plaguing the city’s
sanitary sewers.
Due to the close proximity of the existing
storm sewer and various water and gas
utilities to dense urban areas, the Avon Lake
Municipal Utilities (ALMU) chose the trenchless
method to ensure residential traffic was
not hindered.
The close proximity to utility poles also
made pipe bursting a beneficial way to perform
infrastructure rehabilitation, and it was
estimated to be 30–45 per cent cheaper
than open cut trenching.
Pre-construction inspections undertaken
by Cleveland’s Great Lake Pipeline
Services revealed many signs of deterioration.
These included broken and
cracked pipes, dislocated joints and root
infiltration.

Contractors Utilicon Corp and TT
Technologies began replacing the old vitreous
clay pipe sewer line on Bellaire Road
in July.
At first, approximately 320 ft of highdensity
polyethylene seamless piping were
installed by pipe bursting from manhole to
manhole in about two hours.
The polyethylene pipe was fitted with
a conical shaped head and cutter, and
attached to a hydraulic winch. The cutter
cracked and split the old pipe as the winch
pulled the new pipe into position.
Nearing the end of July, crews had
installed approximately one-third of
Bellaire’s new sewer line and connected six
home laterals, in spite of heavy rain.
By 5 August 2011, approximately 934 ft
of new sewer pipe was installed and workers
connected ten home laterals.
A total of 5,152 ft of sewer pipes will be
renewed when the project is completed,
which is expected to be late August.
The $US1.58 million rehabilitation is the
fourth pipe bursting project undertaken
by ALMU.
Upsizing down under
Pipe bursting has been used in a number of locations across North-Central Victoria, Australia.
Pipe bursting was the technique
selected to replace 256 m of an aged water
main in Eaglehawk, located in Victoria,
Australia.
The project was carried out by Infratec
as part of replacement works identified
through Coliban Water’s Routine Renewals
program.
Operations General Manager Neville
Pearce said “The water main was originally
laid in 1954 and had been subject to a
number of bursts in recent years.”
HDPE was used to replace 222 m of the
100 mm diameter main and 34 m of the
75 mm diameter main.
“This will minimise the impact to our customers
and the environment,” Mr Pearce
said.
Coliban Water conducts routine asset
maintenance all year round across its operations
in north-central Victoria, over an
area of 16,550 square km, often using
pipe bursting. The service area includes 49
towns, extending from Cohuna and Echuca
in the north to Kyneton and Trentham in
the south.
During the last financial year, approximately
3.6 km of water mains were replaced
within 23 distinct projects across Coliban’s
region.
Works are also underway in Bendigo to
pipe burst and replace water mains, which
are past their useful working life and have
failed repeatedly.
This year, an aged sewer main in an
established residential area in Kyneton also
utilised pipe bursting. Approximately 500 m
of 150 mm earthenware sewer was upsized
to 225 HDPE pipe.
Coliban Water said the benefits of using
pipe bursting includes minimising the
impact on the natural environment and built
environment, and the competitive cost of
replacement.
NORDIPIPE
NORDIPIPE is a high quality, glass fibre reinforced liner for
the rehabilitation of water mains. The glass fibre reinforcement
is key in forming a fully structural liner able to withstand high
internal and external pressure, independent of the host pipe.
Diameters from 150 mm (6 inch) up to 1200 mm (48 inch) are
possible.

Improving the hydraulics
In Cologne, Germany, pipe bursting has been used to upsize an oval
concrete pipe and install a new plastic product pipe.
The sewer to be renewed is located
directly at the rear of a higher regional
court building in Hülchrather Street. As
an alternative to microtunnelling, the city
council’s sewage department wanted to
test pipe bursting as a method to replace
two sections of 76 m and 66 m pipe, in the
residential and shopping district.
Pipe bursting was chosen as it can be a
cost-saving possibility to renew damaged
sewers without having to dig trenches and
also minimises the impact on local available
infrastructure.
In addition to addressing leakages from
the joints of the old sewer, the main reason
for the replacement was to improve the
sewer’s hydraulic capacity.
A special challenge
The plan was to replace the concrete oval
profile pipe 350/450, situated at a depth of
4 m, with a circular PP-HM Pipe with an
outside diameter (OD) of 560 mm. Bursting
oval profile pipes and simultaneously upsizing
the cross-section is not carried out very
often with the bursting method, which made
this project a special challenge.
The construction contract was awarded
to Friedrich Wassermann and Weitz and
Co, who sub-contracted ALFES and Sons
GmbH in Olpe.
The required pulling rig was a
Tracto-Technik Grundoburst, which is
available in four performance classes from
40–250 tonne pulling and thrust forces.
The QuickLock bursting rod, which is
initially pushed ahead into the old pipe and
then pulled back together with the bursting
tool expander, and attached to the new pipe,
is a special characteristic of the machine.
The QuickLock’s no-screwing function is an
advantage because the single rods are linked
together, giving pulling and thrust stability
and saving time.
Overcoming compact sandy
ground conditions
In Section 1, the soil inspection carried
out in advance showed loose, sandy soil
and the best conditions for the displacement
work was to expand the bore hole
from 450 mm to 610 mm. The bursting
tools were configured accordingly and a
Grundoburst 1250G, with 125 tonne pulling
force, was applied.
After only a few metres, the work had to
be stopped because the pulling forces for
the displacement work were insufficient due
to the extremely compact layered sandy
ground in the immediate surroundings of
the pipe.
In the end, work continued with
a Grundoburst 2500G instead, with
250 tonne pulling force, and the first section
was completed successfully after only three
working days.
A 4 m deep pit with Grundoburst 2500G.
250 tonne pulling force
The experience gained from the first
section made Section 2 easier, and the
Grundoburst 2500G was applied from the
beginning.
Accordingly, a large machine installation
pit, an intermediate pit – for the five house
connections with an emergency disposal
unit – and a pipe installation pit were set up
according to the regulations and secured
with sheet piles.
The pipe is tensioned tightly with the Burstfix.
The traffic and driveways were only
slightly affected in selected areas.
Pushing the rod
After the installation of the rig, the bursting
rods were pushed through the old pipe
towards the pipe installation pit. Each 225 kg
QuickLock bursting rod was attached and
dismantled with the help of an excavator.
The rod pushing process took approximately
three hours. The installation of the
1.6 m long blade, the expander, with a
Pulling in the new pipe.
diameter of more than 610 mm, and the
connection of the first pipe inside the pipe
installation pit required approximately two
hours of set-up time.
In many cases, marginal conditions –
such as lack of space, depth of the pipe or
groundwater – only allow for the installation
of single pipes. The new pipe in this case
was a 3 m, 560 x 40 mm Schöngen polypropylene
pipe with a multi-latch welding
connection.
Inside the expander there was a connection
for a smaller latch-on rod, which runs
through the new pipe and is connected to
the hydraulically-operated Burstfix tensioning
device at the end of the pipe string.
Tension is necessary for the pipes during
the installation to guarantee a tight connection
for the pipe string.
The multi-latch-welded connection
combines the well-known multi-latch technology
with inductive welding technology,

to minimise the usually long cooling time.
Due to the rigid support and pulling elements
inside the connection, the pipes
can withstand pressure as well as pulling
forces immediately after the inductive welding
process.
The necessary press-on pressure for the
welded pipe is sustained by the latches.
Welding of each single pipe was carried out
in only eight minutes, and installation can be
carried out without long cooling times.
A bit of pipe improv
The pipe installation itself took approximately
one hour for each pipe, including
the connection and welding time. Some
improvisation was required when driving
the bursting tools and pipe string into the
machine pit.
Normally the disassembly is carried out
within the area of the extension frame,
which also operates as an abutment. In this
case, there was not sufficient space inside a
standard extension frame, so two T-beams,
each with a length of 3 m, were placed
between the pit wall and the Grundoburst
in its place, so that the blade and the
expander, as well as the pipe string could
be pulled in far enough for the disassembly.
After these first experiences with the
renewal of oval profiles using the pipe bursting
method, the technology has proven to
be an interesting and economical alternative
to other methods.

These workhorses have dozens of wet and dry uses. They
are able to physically locate utilities – such as gas, electric, water,
phone, cable, and fibre optic lines – more safely using vacuum
excavation.
The machines can also remove directional drilling mud or slurry,
prevent frac-outs and pull a dart, mouse or pig through conduits to
install utilities safely.
Vac-Tron’s Air Series is great for vacuuming out retention ponds,
excavating small rocks and dry sand, and cleaning up non-hazardous
emergency road spills. The machine can clean out areas as
diverse as storm drains, lift stations, manholes, meter boxes, laterals,
car wash pits and grain silos.
With the pressurised tanks, hydraulically-operated, full-open/
locked rear doors (which can be controlled remotely for operator
safety), and industry-leading filtration system, Vac-Tron’s Air Series
machines are top of the line.
The Air Series comes mounted on a heavy-duty trailer with torsion
axles, or can be truck-mounted for mobility. A six-way hydraulic
boom and remote debris trap are optional.
Return dry spoils to the ground while potholing
Want to manage dry spoils and return them to the hole as quickly
as possible without moving your Air Series machine The Remote
Debris Trap can capture the dry spoils and only air travels back.
Use the remote trap to collect dry material and the main debris
tank for wet. When the remote debris tank is full or the job is done,
position the pivot arm over the hole and easily dump the debris
back into the hole – without moving the machine or using a shovel
or backhoe.
Gravity-feed liquid materials from the remote trap into drums for
storage and/or transportation. The pivot arm moves easily from the
rear of the tank to both sides of the machine, and also supports the
remote suction hose for ease of use.

Assessing the risk
Web-GIS based risk management of water and
wastewater pipeline failures
by Varun Raj Sekar, Graduate Research Assistant, and Dr Sunil Sinha, Associate Professor,
Virginia Tech, Virginia, US
Advanced pipeline risk management is contingent on accurately locating the buried pipelines,
the environment and also the physical condition of the pipelines. A web-GIS based state-ofthe-art
platform provides a robust way to assess the risk associated with the failure of water
and wastewater pipelines.
This article focuses on the research
and development of a robust model for the
quantitative risk assessment of water and
wastewater pipelines by taking into account
the likelihood and consequence of pipeline
failure.
Extensive global parameters are taken
into consideration to determine the likelihood
and consequence of pipeline failure, and
these parameters are evaluated by water and
wastewater utilities in the US, and derived by
geographic information system (GIS) using
advanced geospatial tools.
A web GIS-based Pipeline Infrastructure
Database (PID) will be developed as a tool
for utilities to access and tweak the risk
assessment model for each type of pipe.
An exclusive working environment will be
provided for each utility with access to their
respective data to access the global risk
assessment model and export the results
in customised formats as reports, shape
files and databases, and thus this serves
as a comprehensive tool for sustainable
Figure 1: The entire process chart for the web-application development.
utility risk management. Also, this is a global
risk model for strategic infrastructure asset
management and thus for asset allocation,
financial planning, and determining condition
assessment methods.
Background
Based on the feedback from major water
and wastewater utilities across the US, it
has been stressed that there is no GISintegrated
robust risk model available for use
by the utilities. Thus, this research involves
Figure 2: Query Tool and Risk Model results for wastewater clay pipes in the web-application.
Figure 3: Selecting pipelines within a region for data export.
developing a web GIS-based risk model
with intuitive applications, making it highly
useful for utility managers to access risk
models, assess their pipeline infrastructure,
and plan for strategic asset management.
The risk models used by major utilities in
the US, Australia, and also those used in
the oil and gas pipeline industry have been
extensively reviewed. Most of these models
currently used in the industry included limitations,
and many are not GIS-integrated.
Some of the limitations of the major risk
models are listed below:
• Limited parameters for both likelihood of
failure and consequence of failure.
• Models are not trusted by utility managers
as they are not validated or pilot-studied
in other similar utilities.
• A GIS-based approach to query and
visualise other supplementary data along
with the robust model results such as
soil, roads, weather is not yet available.
• Factors and weights used in the model
are not evaluated and weighed by
experts.
Research methodology
A sophisticated web GIS application
has been developed using ArcGIS API for
Flex. The GIS data received from utilities is
processed at Virginia Tech and, using an
ArcSDE connection, the data is hosted on
an Oracle instance at Virginia Tech managed
by Center of Geospatial Information
Technology. Using ArcGIS Server Manager,
REST and SOAP services are published
from the data hosted on the Oracle Instance
through ArcSDE.
Using Adobe Flash Builder, webapplication
and widgets are developed
This is an edited abstract from the ASCE Pipelines 2011 Conference
held from 25–28 July in Seattle, Washington, US.
using ArcGIS API for Flex and MXML
programming language to query and
visualise the geospatial data. This web GIS
application is then hosted using VT Hosting,
and protected with access codes using
JavaScript, enabling utilities to login and
work with their respective data.
Risk is defined as likelihood of failure of
pipe and the associated consequences
due to the failure of the pipe. By extensive
literature review and feedback from
major utilities, parameters that determine
the likelihood and consequence of failure
of water and wastewater pipelines were
identified. The risk model will be developed
using Analytical Hierarchy Process.
A document was prepared which listed
the parameters and tables to mark the
significance of each parameter. This document
was sent out to utility managers,
and the significance of each parameter
was received. The significance of each
parameter represents the relative importance
of this parameter among the others.
The risk model results would have a range
from 1–5 (low risk to high risk), which
would be colour coded on pipes from yellow
to red.
Expected outcome
The key contributions of this research
will be:
• An advanced GIS-based web application
for pipeline data visualisation and querying
using state-of-the-art technology
– Adobe Flex-based environment.
• Access to a robust global likelihood and
consequence of failure model for water
and wastewater pipelines integrated into
the web GIS application.
• The ability to tweak and simulate model
results on the web application, and
export results in desired formats for
effective strategic infrastructure asset
management.
Conclusion
This research has developed an advanced
web GIS-based global risk model for water
and wastewater pipelines, thus aiding strategic
infrastructure asset management.
Currently, there is no advanced software or
application that integrate data visualisation,
querying and web-based risk models. This
web application is highly received by the
water and wastewater utilities as the models
and tools are developed based on the
feedback from major utilities and validated
by them.

The value of advertising online
by Zelda Tupicoff
Does your marketing plan include a budget for online ads Find out why
placing advertisements online is no longer an optional extra.
The best way to get
entire industry coverage
is to take out advertising
in print, online, and have
an event presence.
Creating an online campaign
Branding campaign
This package complements your print and event marketing and
establishes you as a leader in the industry. It includes leading
positions across your industry website and e-newsletter and ensures
that everyone knows who you are and what you have to offer.
Product sales
Aimed at getting results, this option gives you strategic placement of
your advertising across your industry website and e-newsletter, as well
as being able to include product stories on the industry website, which
will help drive traffic through product related searches, allowing you
to reach an even wider audience of people looking specifically for the
products you are supplying.
New product launch
Get out there fast with this time-sensitive option which will help you
create a buzz. This includes strategic positions combined with a
headline banner and a newsletter story about your product launch.
business development
October 2011 - Trenchless International
Remember when you first developed
your company website Just like email, your
website has revolutionised the way you sell
your company, products and services to
the world. Search engine optimisation can
only take you so far, and to reach highly
engaged individuals searching for vital information,
it’s important for your company to
be advertising on the websites that matter
in your industry.
What are the benefits of
advertising online
Timely promotion and flexibility
The immediacy of online advertising
ensures that products can be introduced
to the market very quickly. There is also
design flexibility so web adverts can be
eye-catching and alternate between different
banners. This also allows you to test
different messages in short periods of time
to see what is most effective.
Tracking capabilities
The best thing about online advertising
is its ability to track the performance of
your campaigns. Through using online
advertising your company has the ability
to track every single click and every single
user to see if they end up becoming
customers. Google Analytics, which is
available as a free download, allows you
to track the pathway visitors are taking
to your site and their movements within
your site. Are your online ads generating
traffic Which sites are referring visitors to
your site Google Analytics can help give
you the answers.
Cost effective
Banner advertisements offer great value
due to low production costs. If you have
advertised before, then you know that
just one advertisement may not have
the phones ringing hot – so think about
what your aims are, and perhaps look at
booking a series of advertisements and
combining this with strategically-placed
editorial content. Most websites have
packages available and these should offer
the best value and exposure over varied
periods of time.
Zelda Tupicoff.
High volume
The sheer volume of visitors to industry
websites means that by advertising
you are highly visible to many new
readers and potential leads. Most
industry websites offer site visitors a
free subscription to their e-newsletter,
which is often sent weekly or fortnightly
to thousands of subscribers. By signing
up, these e-newsletter subscribers
have demonstrated a high-level of
engagement. Advertising in e-newsletters
is therefore highly coveted and tends to
be a more exclusive and expensive online
advertising option.
Test the market
Advertising online is a great way to
cost-effectively test if a particular market
is a good fit for your product or service.
If you have a well-designed online advertisement
and you are advertising on the
right industry website then you should
get some decent traffic – and those all
important leads.
Entire industry coverage
The best way to get entire industry
coverage is to take out advertising in
print, online, and have an event presence.
Having a presence in all three will ensure
your brand is at the forefront of a highly
targeted audience. If your company can
only initially afford one or two of these
promotional opportunities, the results will
speak for themselves and you will have a
clear case to argue for an increase in next
year’s marketing budget.
TIP: If you are taking out multiple advertisements
then you should be rewarded
with a discount, but also ask about securing
some editorial coverage to maximise
your impact.
Highly targeted
Visitors to industry websites are usually
looking for information to help them do
their job better, so they are highly engaged.
Every person who views your advertisement
is a prospective customer and you need to
convey instantly that your product or service
is what they need.
Event promotion
Holding an event This is designed to help you promote it. As well as
strategically placed ads on your leading industry site, ensure you are
get an event listing on the events page and see if the salesperson can
organise a news story before and after the event.
Just online, all online
So, you’re a convert – you have decided
your company needs to start advertising
online. But what about your magazine
advertising and exhibiting at prominent
industry trade events The good news is
that online advertising is the perfect complement
to your other marketing efforts. Online
advertising is rarely enough on its own, but
by combining it with print and event participation
in a strategically planned campaign,
your company will receive maximum industry
coverage and make a significant impact.
Writing your advertisement
Perhaps you have tried online advertising
and you didn’t get the great results you
expected Be warned: the advertisement
you run in your print campaign will not be
suitable for online. If you use the same sort
of advertisement you are unlikely to get the
traffic you deserve. For best results you
should make an offer and be instructive (find
out, how to, click here). Through the use of
‘active words’ (for example: order, reduce,
choose, use, apply) you can entice people
to click your advertisement and learn more
about your offer, product or company.

Get on the road
to Niagara Falls
The 2012 Underground Infrastructure Research Conference and Trenchless Technology
Road Show, to be held from 4–6 June at the Scotiabank Convention Centre in Niagara
Falls, Canada, will bring visitors from around the world.
The ZRB Janicki team at
the HDD Rodeo.
conferences
October 2011 - Trenchless International
The conference, which is
being organised by The Centre for the
Advancement of Trenchless Technologies
(CATT), will include paper topics on pipeline
planning and design, construction
and rehabilitation, materials, geotechnical
considerations, inspection and condition
assessment, asset management and sustainability.
These shows feature two days of technical
presentations, field demonstrations and
over 40 technical exhibits.
In 2001, CATT organised and hosted the
2001 Underground Infrastructure Research
Conference and Road Show. More than
180 delegates from nine countries with over
over 50 presentations and technical papers,
discussed buried infrastructure research
needs. Since then, CATT has hosted several
trenchless road shows in 2003, 2005,
2007 with growing number of attendees,
reaching a record high 346 in 2010.
A bit about CATT
CATT was established in 1994 to help
solve Waterloo’s buried infrastructure
problems. Since its inception, the centre
continues to inform the Canadian industry of
research and developments through events
such as the upcoming 2012 Trenchless
Technology Road Show in Niagara Falls,
Canada.
In the early 1990s, the City of Waterloo,
located in Ontario, Canada, began experiencing
premature failures of black fibre pipe
sewer laterals that were in service for less
than 20 years. The rapid usage of 51–200
mm diameter black fibre pipes – made
of compressed vacuum impregnated fibre
paper tubes with bituminous coal tar pitch –
started during World War II when the use of
steel was limited.
Expenses for the large number of premature
failures and construction issues started
to weigh on the city, costing $CAD6,500
($US6,645) to replace each lateral. It led to
a partnership between the City of Waterloo
and the University of Waterloo in 1994, to
explore lower cost and less disruptive black
pipe sewer replacement methods.
This partnership led to the use of pipe
bursting, which reduced the cost of a lateral
replacement from $CAD6,500 (US$6,645)
to $CAD4,500 (US$4,563).
The success of that partnership led to the
development of a research centre devoted
to helping municipalities solve their buried
infrastructure problems. In 1994, CATT
was founded at the University of Waterloo
through a partnership between the university,
City of Waterloo, National Research
Centre of Canada and 25 founding municipalities,
industrial equipment and material
suppliers, contractors, consultants, and gas
company members.
Today, led by Executive Director
Dr Mark Knight, CATT has over 70 members
and represents over 400 individuals
across Canada.
CATT continues to examine innovative
tools and procedures to improve the
maintenance, rehabilitation, and replacement
of the ageing sewer lines, water mains, and
other components that constitute water and
wastewater infrastructure in a cost-effective
manner. Current research efforts focus on
four key areas of condition assessment
for water and wastewater conveyance
systems; system rehabilitation for water and
wastewater conveyance systems; advanced
design and engineering concepts; and
innovative technologies for the management
of buried wastewater, stormwater and
drinking water networks.

Trenchless on show in Poland
The 9 th International Trenchless Engineering 2011 International Conference, Exhibition and Technology
show, held from 15–17 June in the Tomaszowice Manor near Kraków, Poland, was a great success.
Here Trenchless International gives you a quick wrap of the event.
Organised by the Wydawnictwo
Inżynieria sp. z o.o. publishing house, and
endorsed by the Ministry of Infrastructure,
the conference saw 240 registered participants,
and 100 visitors pass through
the exhibition and show. The venue was
attended by the representatives of construction,
production or design companies,
as well as providers of equipment, investors
and academic representatives.
The conference was opened by Editorin-Chief
of Trenchless Engineering Mr
Paweł Kośmider. The main session
was commenced by Professor Cezary
Madryas, PhD Eng., who discussed innovative
solutions in Trenchless Technology.
Sessions included presentations by representatives
of the Wrocław University of
Technology and the 'Polish Waterworks'
Chamber of Commerce on risk analysis
in network infrastructure overhauls, risk
analysis on microtunnelling and horizontal
directional drilling (HDD) technology,
as well as the Chamber’s guidelines on
trenchless technical renovation of water
and sewage pipes in urban areas.
For the first time, the conference held a
panel session which discussed the current
status and prospects for the development
of drilling liquids. The well-attended
panel session was conducted by Robert
Osikowicz, and included discussion
from the panellists Marcel Bijleveld from
Cebo Holland, Frank Canon from Baroid

ISTT ESC Profile
October 2011 - Trenchless International
5 minutes with Enrico Boi
Continuing our new feature, Trenchless International introduces you to another member of the ISTT
Executive Sub-Committee. Here we speak to Enrico Boi from the Italian Association of Trenchless
Technology (IATT), who says he fell in love with trenchless at first sight.
The ISTT, which was established in
1985, beginning with a one-time conference,
has been instrumental in educating
and promoting the benefits of Trenchless
Technology around the globe for over
25 years. The members of the ESC are
an important part to the board and help
in running an efficient day-to-day society,
and are empowered to act for the full
board.
When or how did you first
become involved in the trenchless
industry
The first time I saw Trenchless Technology
in action was probably about 20 years ago
in university; it was love at first sight! I got
involved with the industry about seven years
later, mostly with underground mapping in
relation to horizontal directional drilling (HDD)
projects.
Which organisation are you from
and how long have you been on
the ESC
I am from TST Engineering, a group of
companies that specialise in underground
mapping and location, as well as other side
services. I am also responsible for international
relations for IATT. I was elected onto
the ESC during the 2010 ISTT No-Dig held
in Singapore, and this is my first mandate.
What has been the most
memorable project you worked on
It is hard to say – probably the underground
mapping project for the Light Rail
and the Metro in Dublin, Ireland. Six years
of pushing the limits of technology and
procedures to build new standards and
create new limits. However, probably the
most challenging project is the one I am
directing right now in Italy; the pilot project
for the national GIS infrastructure in relation
to underground networks.
What do you see as the
most important role and/or
responsibility of the ISTT
Besides the promotion activities that
ISTT develops every year, the association
can be a worldwide reference for training
Enrico Boi with IATT Chairman Paolo Trombetti.
and standards of our industry. The society
can also be a stimulus to push co-operation
between Affiliated Societies maximise
results using cross border co-operation.
How do industry initiatives, such
as conferences and publications,
help you in promoting Trenchless
Technology in your country
These activities are indeed very valuable
for the promotion of the technology for the
single countries. This is due to the fact that
promotion is mainly related to new products
or technology, and publications and
conferences are mainly built on state-ofthe-art
material.
What are some of the main
challenges your country is facing
with Trenchless Technology and
how do you think these can be
overcome
Probably the biggest challenge is to
break the common habit of using classic
technology instead of trenchless. Some of
the reasons this happens is related to the
knowledge of the matter itself, not spread
as the classical one for obvious reasons,
and this can be overcome with promotion
of Trenchless Technology.
Enjoying the Berlin No-Dig 2011 Chairman’s
Dinner.
Another aspect to be considered is the
inertia of new ideas for how trenchless can
become common use. This aspect should
not be considered of secondary importance,
because it is part of human nature.
The best way to overcome this is to change
the load of balance between the technologies
facilitating to the use of trenchless – for
example, during authorisation procedures
or reducing the time for the acquisition of
all the permit for the project. This is one of
the directions we are following in Italy right
now; the IATT is consulting with lawmakers
to pave the way for trenchless.
Visit
www.istt.com
for further
information.
The ISTT is the umbrella organisation for trenchless technologists in over
30 countries of the world. In 30 countries, groups of trenchless technologists
have their own national groups that are affiliated, while the remainder are registered
directly with the ISTT.
Trenchless Technology covers the repair, maintenance, upgrade and new installation
of underground utility services using equipment and techniques which
avoid or considerably reduce the need for excavation. The ISTT promotes
research, training and the more extensive use of Trenchless Technology through
publications, co-operation with other NGOs, an annual international conference
and an interactive website.
Trenchless Technology is recognised as an environmentally sustainable technology
and is particularly suited, for use in densely populated urban areas by
reducing disruption to peoples daily lives, social costs (traffic congestion, damage
to road surfaces and buildings, air quality), noise and dust. Trenchless
technologies also have a considerably reduced carbon footprint compared to
trenching in most situations.
