21.3 Intent and requirement.
The intent of the tender is survey, design, engineering and construction of water
treatment plant to augment the capacity of existing WTP.
Present phase and future requirement :
The shortfall in the supply for the intermediate and ultimate stage of the project is
8 MLD and 24 MLD respectively. Considering the high turbidity of water during of
monsoon months, leading to the over-loading of the clari-flocculator of 34.05 MLD
WTP, it is proposed to construct clari-flocculator identical in size and shape and
having same level of construction as that of the clari-flocculator of existing
34.05 MLD water treatment plant. The incoming raw water from existing rising
main and proposed rising main (34.05+8MLD) shall be shared by
2 clarri-flocculator @ 42.05/2 i.e. 21.025 MLD thereby reducing the load of the
existing clari-floculator. The clarified/settled water from both the clarifier shall be
shared by both the filtration plant by interconnecting the clarified/settled water
channel of both the clari-flocculator. The filter house and associated plant shall be
constructed to yield 8 MLD of water and with provision for future expansion of the
plant to yield 24 MLD to meet the shortfall for the ultimate stage.
21.4 Scope of work.
The scope of work covers survey, design, engineering and construction of civil
work components of the WTP, including selection, manufacture, supply and
delivery to store at project site of electro-mechanical equipments and
instrumentations properly packed for transportation in F.O.R. site basis, received at
store and site including loading and unloading at all terminal routes, safe storage,
installation, pre-commissioning activities, trial run, commissioning, field testing
operation and maintenance for a period of 3 months of the plant with all accessories
and ancillaries. The associated plant and equipments to be installed shall be
compatible with automation control and visualization system provided with
centrally controlled and monitoring system. Automation control and visualization
system is however outside the scope of this tender.
It is the responsibility of Bidder to have thorough understanding of reference
document, site condition and specifications. The intending Bidder shall be deemed
to have visited the site, studied the condition, collected relevant and required data
before submitting the bid to make the bid complete and correct in all respect. Nonfamiliarity
with the site condition will not be considered a reason either for extra
claim or for not carrying out the work in strict conformity with the
specifications/acts/code of practices/rules and regulations of local Electrical
inspectorate.
