Mumbai-IV water supply project
Brihan Mumbai Municipal Corporation (BMC) is providing drinking
water supply to Mumbai City and suburbs to the tune of 2978mld,
serving a population of 11.85 million. BMC now proposes to further
augment water supply to Mumbai by 455mld by the development of a
middle Vaitarana source under the Mumbai-IV Water Supply project -
which involves construction of a dam on Vaitarana River, between
upper and lower Vaitarana storage, conveyance of water from lower
Vaitarana plus treatment and storage. The water from middle
Vaitarana dam will be released into the lower lake also called
Modak Sagar in a controlled manner from where it will be drawn for
treatment and onward supply to the city.
Long distance tunnelling of Mumbai Water Supply
Project
Mott MacDonald's engineering team is involved in reviewing
available data and carrying out detailed hydraulic and structural
designing of intake works, 4.1 m bore dia 7.5 km long tunnel; 15.1
km long, 5.5 m Dia. high pressure tunnel and 900 mld pumping
station and water treatment plant. The scope of work also involves
preparation of bid documents, construction drawings, rate analysis,
detailed bill of quantities and cost estimates. Additional
responsibility involves studying the feasibility of hydropower
generation from the middle Vaitarana dam.
Sardar Sarovar canal based drinking water supply
project
The Government of Gujarat has taken a proactive initiative to
supply drinking water through Sardar Sarovar project, which has
ear-marked 1.06 M ac-ft of water for this purpose with River
Narmada as the source. It includes provision of 3582mld of drinking
water for domestic as well as industrial consumption in 8215
villages and 135 towns of Saurashtra, Kutch, North Gujarat and
Panchmahal. Out of the above quantity, 2900mld of water is meant
for domestic consumption and 682mld for industrial purpose.
Mott MacDonald had been responsible for preparing EPC based
contract documents for the design and construction of a bulk water
supply system.
The source of supply is Vallabhipur branch canal taken from Narmada
main canal. The raw water from the branch canal is lifted and
stored in a pond. The water is transmitted from Vallabhipur to
Rajula through pumping and gravity mains 306km long with pipe
diameter varying from 900mm to as large as 1800mm. We were also
responsible for carrying out the SCADA analysis for remote
monitoring of the bulk water supply system.
Mysore water supply scheme
The project as part of the IV Stage Water Supply Augmentation
Scheme for Mysore City, involves all the major components of water
supply scheme like intake works, sump cum pump house, rising main,
water treatment works and subsequent distribution. The project
involves detailed civil, mechanical and electrical engineering
design of all the major components and construction of ancillary
structures such as valve chambers, thrust blocks, pipe supports and
steel pipe bridges across irrigation canal.
We have been involved in preparation of layout plans, detailed
engineering design, estimation, and prequalification of
contractors, preparing tender documents, bid evaluation,
supervision of construction and quality assurance certification.
Mysore City Water Supply Augmentation
Bhadaravati water supply project
Mott MacDonald was awarded the work of feasibility and design of
water supply distribution system for Bhadaravati city - which has a
population of 156,000 - having about 90km of distribution network
of PVC/CI pipelines. Our scope covered review of land use plan,
review of current and proposed water supply schemes, analysing the
existing distribution network, developing concept plan, carrying
out surveys, detailed hydraulic and structural designing along with
cost estimations and financial analysis.
