Action follows complaints from residents of Bharathi Park.

Two days after the residents of Bharati Park complained of sewage mixed water supplied to the area, the Corporation has on Wednesday replaced a damaged pipeline to remedy the situation.

On Wednesday, after ascertaining that the leak had happened because of damage to a drinking water pipeline at the NSR Road – Raja Annamalai Chettiar Road Junction, the Corporation officials swung into action to replace the pipeline. The officials used a cast-iron casing pipe to replace the damaged PVC pipeline.

According to sources, once the work was complete, the water supply managers would pump water to check if there was any further mix of sewage with the drinking water. If there was one, they would identify other spots where the water supply pipeline could be damaged. Else, they would close the work spot and restore supply.

Prior to identifying the aforementioned spot, the water supply managers had dug at a few places at Bharati Park and along NSR Road to know where the leak had happened. Even as they kept digging at a few places, the managers also cleaned the supply lines with chlorine to ensure that the quality of water was good after resumption of supply.

The sources said that if there were no further leaks, the Corporation would supply water by Friday to the areas that got sewage-mixed water on Monday last. Residents of a host of residential colonies in the area had complained that the water supplied resembled black phenyl and was with a foul odour. They had also raised the issue with the Commissioner, G. Latha.

Soon after the issue came to her notice, Ms. Latha asked the water supply managers to coordinate with the engineers in the JNNURM wing to ensure that during the execution of the storm water drain work, no water supply pipeline was damaged because supply of sewage-laced drinking water to the residents was a very serious issue.

She also asked City Engineer in-charge K. Sugumar to ensure that such an incident did not recur.

 

Metro Water tanks up 21 new vehicles for city supply

Metro Water tanks up 21 new vehicles for city supply

Metro Water on Friday added 21 more tankers to its fleet of 335 to quench the thirst of Chennaiites as the water levels in the reservoirs slowly dwindle.

A senior Metro Water official said the new tankers had better capacity than the existing ones and would be supplying 20,000 kilolitres of water per trip. These tankers would make 320 trips a day and were different from the ones in the fleet. “Earlier tankers had a capacity of 9,000 and 6,000 kilolitres per trip. The new tankers will have a capacity of 20,000 kilolitres per trip,” said the Metro Water official.

This is also part of Metro Water’s contingency plan to ensure that the city gets proper water supply as the water levels in the reservoirs dwindle. Currently the four reservoirs – Poondi, Cholavaram, Red Hills and Chembarambakkam – have about 25 per cent of total water.

The Metro Water spokesman said the need for new water tankers arose after it installed tanks on streets to provide water to people.

To beat the heat, Metro Water plans to procure 15 MLD of additional water from Poondi and Tamaraipakkam wellfields, besides getting additional 20 MLD from Neyveli acquifer and 55 MLD from other sources in Neyveli.

But all hopes are now on the monsoon. “If we get a normal monsoon, then the water crisis may be over. We are pinning our hopes on a thunder storm which is likely to bring rain on Monday,” a Metro Water source said.

Meanwhile, Water Resource Department sources told Express that Chennai would get around 300 cusecs of water a day from the first week of June once the temporary works by Andhra Pradesh irrigation department in Uppalamadagu canal near Kalalahasti get over. But the city would get the full quota of 1,000 cusecs a day only after the repair works are done.

Water supply from Kandleru reservoir was suspended after the repair works was taken up. As per an inter-state agreement in 1976, Tamil Nadu is eligible for 15 thousand million cubic feet of water between April and June under the Telugu Ganga project.

Water scheme launched

Staff Reporter

With the inauguration of the water supply improvement scheme for Cumbum town by Chief Minister J.Jayalalithaa through videoconferencing on Thursday, the Cumbum Municipality will be able to supply 90 litres per capita per day (LPCD) to its residents from July 2014. The new scheme will mainly benefit Cumbum and Gudalur Municipalities, according to C.Chandran, Municipal Commissioner.

The TWAD Board would implement the scheme at an estimated cost of Rs.18.80 crore in 18 months, he added. Four overhead tanks would be constructed, new distribution pipelines laid and a new motor pump set with filter beds and gravity main would be set up to a distance of 11 km from the main head works, he added. Mr.Chandran said the Central Government granted Rs.13.12 crore and the state government Rs.1.64 crore, while the urban local body’s contribution was Rs.4.04 crore.

The municipality would receive Rs.1.50 crore from the Gap-Filling Fund 2011-12 and Rs.1 crore from the Integrated Urban Development Mission 2011–12 to raise money for its contribution, he noted.

Earlier, two water supply schemes had been implemented for the municipality to supply protected drinking water to a population of 69,183.

The first combined water supply scheme was launched in 1960, covering Cumbum Municipality, Gudalur, K.K.Patti, C.Pudupatti, Hanumanthanpatti and Uthamapalayam town panchayats to supply 1.5 million litre (MLD) per day of water.

To cope with the population growth and rapid developments, another combined scheme was implemented in 1987 with Mullaiperiyar River Lower Camp as its prime source. Three MLD of water had been provided under the scheme, he added.
