Middle Vaitarna dam project gets a push

The much-awaited water project for the city got a go-ahead with the laying of the foundation stone for the Rs 505-crore Middle Vaitarana Dam project.

“Water supply projects worth Rs 2,000 crore that were earlier rejected by the Centre will get preference,” said Union Urban Development Minister Jaipal Reddy at the function at the Bhandup Water Treatment Plant.

The project will be ready by April 2012 and it will supply 455 million liters of drinking water everyday. Middle Vaitarna Dam will be the first Roller Compacted Concrete dam constructed by a Chinese company. The proposed height of the dam is 105 m and length is 530 m.

Currently, Mumbai has shortage of 800 MLD (million litres daily) of water.

At present, the city gets 3450 MLD of water against its demand of 4200 MLD

The project was recommended by Chitale Committee in 1993 but was delayed due to delay in getting funds as well as environmental and security clearance from the Centre.

The water supply projects mentioned by Reddy includes replacement of Tansa pipeline worth Rs 900 crore and a tunnel form Gundavli in Andheri to Bhandup worth Rs 1,100 crore.

Following a request by Gurudas Kamat, Reddy said his ministry would consider the BMC’s plan to set up a desalination project to make sea water potable.

“I will consult the finance minister. It needs huge money but people of Mumbai deserve it,” Reddy said.

Once the Middle Vaitarana dam is completed, water from the catchment will be brought to the Lower Vaitarna and supplied to the Bhandup treatment plant through a 40-km pipeline. It will be then treated and supplied to the city.

Shiv Sena Executive President Uddhav Thackeray asked the Centre to help in the other water supply project like Gargai and Pinjal that would provide additional 1300 MLD a day.

Reddy also laid the foundation stone at the project of partial closure of Deonar and full closure of Gorai dumping ground. “Mounting waste causes pollution. Bombay authorities have done what is done in the advanced countries. Mumbai has always been a leader,” said Reddy.

Water projects Centre rejected will be reconsidered: Reddy

With the Assembly polls approaching, both Shiv Sena and local Congress leaders tried to cash in on Mumbai’s water shortage on Tuesday, forcing Union Minister for Urban Development Jaipal Reddy to promise central funding for water projects. Giving in to their demands, Reddy said water projects worth Rs 2,000 crore earlier rejected by the Centre under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) would be reconsidered. A special waste-water treatment plant and a desalination project would be recommended for financial assistance. It would augment and boost the water supply network in the city.

Speaking at the foundation stone laying ceremony of middle-Vaitarna Dam Project that would provide additional 455 million lakh litres of water per day on completion in 2012, Reddy said that Mumbai’s development projects will be given special attention. “We will consider replacing Tansa pipelines and building a tunnel from Gungavali to Bhandup estimated at a cost of Rs 1,100 crore,” Reddy said.

This was announced after Shiv Sena executive president Uddhav Thackeray and MP and State Minister for Telecom Gurudas Kamat prodded Reddy to give approval for the projects that were earlier rejected. Mumbai and Maharashtra have received maximum funding under JNNURM and therefore further financial assistance for these two projects were rejected earlier this year.

“Although the middle-Vaitarna project will provide drinking water, the population will increase by the time the project is completed. Desalination projects require huge money but the citizens of Mumbai deserve it. Centre will have to provide for 90 per cent of the funds but I will take this project ahead and talk to the finance minister,” Reddy added. He also said that water treatment plant on lines of that in Singapore to purify sewerage water will also be considered.

Mayor Shubha Raul said Mumbai is surrounded by sea on three sides and therefore desalination projects should be given approval so that sea water can be treated and made potable. “If we use sea water, then we would not have to depend on rainfall. The Centre should also provide funds for Gargai and Pinjal water projects,” said Uddhav.

Kamat and Congress Mumbai chief Kripa Shankar Singh also demanded the Centre’s approval and financial assistance for the project.

The BMC, on the demand of Sena corporators had a few years back, asked IIT-Bombay to study the treatment of sea water to make it potable and the process was found to be way costlier than treatment of sewerage water and was therefore termed as not feasible.

BWSSB plans mega water treatment plant

N R Madhusudhan

BANGALORE: Bangalore Water Supply and Sewerage Board (BWSSB) will construct the country’s second biggest water treatment plant at Torekadanahalli (TK Halli) to supply drinking water to the city under Cauvery IV stage II phase project.

BWSSB will be supplying 500 million litres per day (MLD) under Cauvery IV stage II phase and the water treatment plant will have a capacity to purify 500 MLD of water. Delhi Jal Board has constructed three water treatment plants of 550 million litres capacity.

Raw water from Cauvery river will be pumped from Shiva Anicut to TK Halli, which is at a distance of 18.5 km, through open channel and steel pipeline. The water will be purified and treated at TK Halli and will be pumped to the city in three phases, after treatment.

Nine working pumps and five standby pumps of high pumping capacity will be installed at TK Halli, Harohalli and Tataguni to pump water to the city, which is 98 km away from TK Halli. These pumps will be regulated with the supervisory control and data acquisition system.

The water will be pumped to the city in a steel pipeline of diameter 2700 millimetre and the water will be directed to six different ground level reservoirs (GLR) that are to be constructed at Jambu Savari Dinne, Uttarahalli, Parappana Agrahara, Gandhi Krishi Vignan Kendra, OMBR and Hudi.

These GLRs will have a collective storing capacity of 147 million litres of water and will help in regulating and diverting water to different parts of the city through 40 GLRs that are already existing and nine GLRs that will be constructed with aid from Bangalore Development Authority at different parts of the city.

All the aforesaid works will be undertaken under Cauvery IV stage II phase and will be jointly funded by Japan government and state government.

One of the BWSSB officials said, “Some of these works are yet to commence. If everything goes according to the plan, they should be completed by the end of 2012.”
