Under Brazil Trenchless International interviewed Associação Brasileira de Tecnologia não Destrutiva Chairman Paulo Dequech about Brazil’s utilities, upcoming events, Affiliated Society, and projects. According to Associação Brasileira de Tecnologia não Destrutiva (ABRATT) Chairman Paulo Dequech, the majority of Brazil’s underground water and wastewater assets range between 80- and 40-years-old. Currently, the condition of Brazil’s water pipelines are very badly deteriorated, and consist of pipes made of cast iron, steel and from more recent installations, PVC. Wastewater pipelines are in a worse condition than water pipelines, and are comprised mostly of clay, concrete and cast-iron. The renewal of underground assets is becoming a high priority to the Brazil Government, particularly in major urban centres. Sabesp, for example, has its own assets renewal program supported by JICA from Japan. The company intends to replace all old water pipeline networks over the next three years. In progressing this project, the next step will be to rehabilitate the large watermain located in downtown São Paulo. The government also intends to start the rehabilitation of large diameter sewers as soon as appropriate funding is allocated. Brazil October 2012 - Trenchless International Water and wastewater issues Mr Dequech says Brazil has highly experienced contractors and engineering companies, who have the material, man-power and technology to rehabilitate and upgrade Brazil’s infrastructure, but there is a lack of government funding in the areas of water and wastewater. Brazil’s upcoming projects The biggest sewer project currently underway in the region is the Tiete River Remediation Program in São Paulo. The project has so far utilised horizontal directional drilling (HDD) and microtunnelling, with both techniques proving highly successful in their installations. Mr Dequech says Brazil has large demands for upgrading sewer networks with thousands, perhaps even millions, of kilometres requiring installation throughout the country. He predicts that Trenchless Technology will be required on the majority of jobs. Tietê River Remediation Program In the period from 1900 to 2010, São Paulo’s population grew to 10.65 million inhabitants. If the wider metropolitan area is included with its 38 municipal districts, São Paulo has a population of 19 million. This rapid increase in the city’s population gave rise to a number of infrastructure challenges, including traffic jams, floods, and problems with sewage treatment and water supply. Today, 85 per cent of houses are connected to the collection network in greater São Paulo. The total length of the sewage network is currently 44,600 km, including 490 treatment plants Project crew working on the Project Tietê. and 5.8 million house connections. The city’s sewage treatment capacity stands at 43,500 litres per second. In October 1990, Project Tietê was launched to improve the wastewater network and clean the highly polluted 1,000 km long Tietê River, which runs through São Paulo. The first phase of Project Tietê ran from 1992–1998, and included the construction of 1.5 km of collection networks and 315 km of trunk collectors, which expanded the collection network to serve 250,000 families. Quick facts on the Tietê River Remediation Program Project Operator: Sabesp Total length of sewer: Approximately 90 km Length of HDD drive: 5 per cent of total sewer length Length of microtunnelling drive: 95 per cent of total length Fund Agency: World Bank (50-60 per cent) and Sabesp (50-40 per cent). The mts1500S4 in action on the Project Tietê. The second phase of Project Tietê, 2002–2008, saw the installation of 165 km of trunk collectors, 1,426 km of collection networks and the cleaning of the Pinheiros River. The third and final phase of the project started in 2009 and is set to be completed in 2015. This phase will involve the construction of 580 km of trunks, collectors and interceptors; 1,250 km of collection networks; 200,000 household sewage connections and three new treatment plants. The primary goals of this phase are to increase wastewater collection from 85 per cent to 87 per cent, and to raise sewerage treatment from 72 per cent to 84 per cent. The project is utilising a mts Perforator excavator in the third phase of the project. São Paulo’s water utility: Sabesp The predominant stakeholder for water management in São Palo is Sabesp, a mixed capital company responsible for water supply and sewage collection and treatment in 363 municipalities in the state. Sabesp is one of the largest sanitation companies in the world in terms of population covered. Sabesp was created in 1973 to implement the National Sanitation Plan (PLANASA) – a Brazilian Government program that financed capital investments and helped develop state water and sewage companies, using funds from the FGTS (Workers’ Severance Pay Fund). Since then, other publicly – or state-owned companies related to water supply and sewage collection and treatment in the state have been merged into Sabesp. In partnership with private companies, Sabesp also operates in four other municipalities, Mogi-Mirim, Castilho, Andradina and Mairinque, in addition to providing advisory services in Panama and Honduras. It also maintains partnerships with the state sanitation concessionaires in Alagoas and Espírito Santo. Currently, 27.6 million people are supplied with water and 20.5 million with sewage collection. In addition to basic sanitation, Sabesp is also equipped to provide drainage, urban cleaning, solid waste handling and energy services. In order to ensure high-quality services, the company maintains a massive structure and has invested around $US4.433 billion over the last five years. Between 2012 and 2015, it plans to invest a further $US3.94 billion to ensure that it advances towards its commitment to provide water and sewage services to everyone in its operational area by 2018. Brazil October 2012 - Trenchless International 14 15
Brazil A wealth of investment opportunities await in Brazil Brazil is a democratic country with a solid economic position, strong reserves (more than $US119 billion), low inflation and a very attractive interest rate for investment. Eight indicators that Brazil is a promising region for future investment: 1. $US1.1 trillion of GNP means that every investment plan means billions of dollars 2. Infrastructure (transport only) will take 1 per cent of GNP per year till 2023 3. Sewer investments, for a country that collects only 40 per cent and treats less than 20 per cent, means a lot of potential opportunities 4. Sewer rehabilitation in state capitals require a huge investment of $US11.9 billion till 2023 5. Fibre optic and broadband in Brazil means thousands of kilometres of buried cables 6. Hundreds of thousands of kilometres of cast iron and asbestos cement pipelines still supply potable water in the old downtown of huge cities across Brazil 7. Scheduled international events increase all prospects (Soccer 2014 and Olympic Games 2016), and everybody knows what that means 8. Billions of dollars worth of investments in energy projects, including plans by one of the world’s largest oil companies to build more than 7,000 km of oil and gas pipelines. Meet the Society: ABRATT SEE US AT 14 ABRATT was established in 1998, under leadership from Sergio Pallazzo, in order to promote, develop and organise Trenchless Technology in Brazil. The founding group was comprised of engineers, contractors and technicians who worked with Trenchless Technology. Mr Pallazzo has a lot of experience in the trenchless industry, and was familiar with US contacts from working with the ISTT. He was able to organise the Society’s establishment in accordance the format of existing international societies. ABRATT has been affiliated with the ISTT since 1999. BOOTH NO. Sergio Palazzo and ABRATT Chairman Paulo Dequech. Running ABRATT The board has remained essentially the same since its foundation. Mr Dequech has held the role of Chairman since year 2008. The board is completed by Helio Rosas, Liberal Ramos Filho and Sergio Pallazzo. All board members are contractors or equipment dealers in Brazil with more than 15 years’ experience. The Society does not have formal councillors established for areas or provinces of Brazil, but does have members in most important country regions, who are informally in charge of promoting the Society, as well as the use and benefits of using Trenchless Technology at a local level. Hosting the 2012 ISTT No-Dig Conference In 2012, ABRATT has the honour of welcoming the ISTT to Brazil to host the prestigious international No-Dig event. The ISTT No-Dig 2012 will be held 12–14 November at the Expo Transamérica Convention Center in São Paulo, Brazil. Brazil is the hub connecting South America to the wider world. ABRATT has worked extensively promoting the event, and has been successful in attracting participants from all over the globe. October 2012 - Trenchless International 16
