In the pipeline: Salem water for city

CHENNAI: The Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) has identified a new water source in Thoppur near Salem that can supply 15 thousand million cubic feet (tmcft) water to Chennai.

This is being done to meet the expected growth in demand for water in the future. The water will be transferred to the city in three phases of 5 tmcft each.

The 15 tmcft of water will help supply water to over 63 lakh people in the city. Consultants have submitted an interim report to the government and the project will be sanctioned after the full report is submitted by the consultant appointed by CMWSSB.

With the water demand in Chennai expected to shoot up to 2,248 million litres per day (mld) by 2026 and the availability pegged at 1,615 mld, it is vital to find additional water sources.

Apart from setting up two desalination plants in the suburbs, each of which can provide 100 mld, and a proposal to set up a 200 mld desalination plant, the government is also trying to find new water sources.

In the first half of 2009, the CMWSSB appointed a consultant to identify new water sources for Chennai.

They were given 15 months to submit a report, specifying the new source and the feasibility of laying pipes from the water source to Chembarambakkam or Poondi lakes.

The consultant has submitted an interim report to CMWSSB and pointed out two new sources. "One is on the Bangalore highway and the other near Salem," said a senior CMWSSB official.

The one near Bangalore was rejected as Metrowater would have to take a lot of road cut permissions to lay pipes to bring water to the city.

The CMWSSB is planning to bring the water to Mettur and then pump into a pipeline to Chennai.

"The total distance is around 265 kilometres. We will have to take permissions from collectors and other departments to lay the pipes. It will take some time before we bring the water to the city," said the official.

Surface and ground water account for the main sources of supply to CMWSSB. While Poondi, Cholavaram, Porur, Veeranam and Chembarambakkam lakes and Krishna river are the surface sources of water, Minjur,Poondi and Tamaraipakkam constitute the groundwater sources.

"The Krishna water scheme was planned in the 1970s keeping in view the demand after 30 years. Similarly, we are foreseeing the demand after 30 years and trying to identify water sources," said the official.

At present, 760 mld of water is supplied to the city, almost three times the quantity supplied in 1978 (240 mld).

The water treatment capacity today is 1,398 mld, compared to 182 mld in 1978. The number of Metrowater connections has increased from 1,16,000 in 1978 to 4,97,811 today.

“Piped water supply must be metered”

Staff Reporter

Why should not the piped water supply in the city be metered? Can we allow unmindful exploitation of a precious resource by a few?

These were the pointed questions raised by one of the participants at the Reader Connect programme on “Water Resources of Madurai - past, present and future,” organised here recently. “Our basic weakness is to exploit such resources to the maximum. When there is no concern for judicious usage of water, should we not meter the supply to put an end to its wastage,” Prof. Velrajan of Thiagarajar Engineering College asked.

It was totally unjustified to collect the same Rs. 418 (for domestic connections) as water charges from a family of two members and also from a family of 10. When people are ready to pay for the quantum of electricity they consume, they should also pay the same way for water also, he said.

Pointing to various measures suggested by the speakers at the meeting to augment water resources, he said that there would not be any need to add to existing water resources, if people start using the available resource judiciously. “Conservation is also one of the tools in better water supply management. It will benefit in the longer run,” he said.

A retired hydrologist from Tamil Nadu Water Supply and Drainage Board, V.C. Ramakrishnan, expressed the same sentiments. “People do not know the value of water. We should create model areas in the city where metering should be made mandatory to study its utility,” he said.

Another participant, Kondappan, complained of illegal water tapping with the help of electric motor pumps. People were also wasting the treated water for gardening, he said. He suggested the Corporation officials to go in for surprise checks to prevent illegal tapping.

Responding to questions, the Corporation Commissioner, S. Sebastine, said that fixing water meters was one of the conditions under the Jawaharlal Nehru National Urban Renewal Mission. However, he said, there was no quality water meter available in the market. “Besides, people also ensure that the meter does not work so that they will not be charged for their actual consumption,” he said.

Sewage issue

An engineer from the Tamil Nadu Water Supply and Drainage (TWAD) Board, Murali Manohar, expressed his concern over sewage water being allowed to drain in the storm water drainage under construction in the city. “It is supposed to source for the fresh water. Sewage should not be allowed into it,” he said. The Corporation Chief Engineer, K. Sakthivel, said that once the underground drainage works in the city was completed all sewage would be connected to the underground drainage.

Another participant, Jayakumar, wanted the local bodies to ensure that new residential areas coming up on the extension areas should have centralised rainwater harvesting structure. He suggested that bigger apartments should be made to provide facilities to treat waste water.

One of the participants, Kannan, complained about bursting of pipeline at frequent intervals near HMS Colony that led to wastage of drinking water.

J. Rajamohan of Tamil Nadu Chamber of Commerce and Industry wanted the local body to sink percolation borewells at regular intervals on the concrete bed of the storm water drains to help recharge of ground water. He said the cost could be borne by the local people.

The event was sponsored by State Bank of India.

 

Councillors review progress of Pilloor water supply work

Councillors review progress of Pilloor water supply work

Staff Reporter

Coimbatore Corporation councillors and officials on Monday visited the Pilloor dam and reviewed the progress of work in the Pilloor Phase II drinking water supply project.

A release from the civic body said Mayor R. Venkatachalam, Deputy Mayor N. Karthik and officials also visited the places where the pipeline for the main supply line was being laid, and the 30-lakh-litre tank in Ramakrishnapuram.

Councillors from the Congress and the Dravida Munnetra Kazhagam and a few others, barring those from the All India Anna Dravida Munnetra Kazhagam, took part in the visit. A few councillors of Communist Party of India and Communist Party of India (Marxist) also kept away.

The officials explained the work being undertaken and said they were hopeful of completing the work by September.

A few days ago, a team comprising Mayor, Deputy Mayor, officials and chairmen of zones visited the dam and places where work was in progress. A release issued then said the civic body would be able to get an additional 20 million litres a day if the Pilloor Phase II pipeline was cleaned and additional water was pumped from the Pilloor Phase I scheme.

It also said that the water treatment plant was on the verge of completion.

AIADMK councillor P. Rajkumar said the two visits the Mayor had organised were an “eyewash” trying to mislead the public on the progress of work. The visits had come after Minister S.P. Velumani had urged the Corporation to speed up the work and inspected the site to study the progress made.

The previous AIADMK Government had initiated the Pilloor Phase II drinking water supply project and that was the reason the Corporation was not speeding up the work, he said.

The AIADMK councillors had repeatedly raised the issue of water shortage and slow progress in the project, he pointed out and said when the issues were raised in the Council the Mayor had done very little in that regard.
