Water quality monitors at 50 spots soon

Soon, city residents may not have to wait endlessly for rectification of water supply and sewage-related problems.

In a few months, Chennai Metrowater will introduce automated inline water quality monitoring system to constantly check the quality of water supplied to residents.

On Tuesday, municipal administration and water supply minister, K.P. Munusamy, announced in the State Assembly that the monitoring devices would be fixed at 50 spots across the city, at a cost of Rs. 1.8 crore.

At present, field staff members of Metrowater manually collect 3,500 water samples every day, from water distribution stations to domestic service connections.

According to an official, once the GSM/GPRS-enabled integrated water quality monitoring system is in place, Metrowater will be able to continuously monitor the quality of drinking water.

The devices that will be attached to pipelines in various places, including MRC Nagar and Anna Nagar, will test quality during the hourly flow of water. The sensors in the device will transmit the data to a central control room to be set up in the head office.

Three parameters — turbidity, residual chlorine and PH levels — will be monitored at regular intervals during a day. At present, it takes time to test samples in a water lab, detect contamination and communicate to the authorities concerned. This causes a delay in the rectification process.

With the new system, officials need not wait for complaints on contamination or lab test results to rectify a contamination problem.

Similarly, sewage overflows are expected to be minimised, particularly during the monsoon. For the first time in the State, Metrowater will implement automated operations in the 218 pumping stations across the city. Now, the sewage stations are operated manually.

Ultrasonic level detectors will be installed in sewage-collection wells to automatically pump sewage when the level is high and stop when the flow is low.

Minister Munusamy said in the Assembly that the amount of drinking water supplied to city residents would be increased from the existing 831 million litres a day (MLD) to 1,000 MLD by 2016, when the various projects to create new water sources are completed.

Drinking water project launched

To meet requirements of Kovilpatti residents.

The much awaited drinking water project to meet the requirements of Kovilpatti residents has been launched under the Kovilpatti municipality water supply improvement scheme.

The project was taken up at a cost of Rs.82 crore under the aegis of the Urban Infrastructure Development scheme, sources from the Tamil Nadu Water Supply and Drainage Board told The Hindu here on Wednesday.

Eighty per cent of the total cost would be incurred by Central Government, ten per cent by State Government and the rest by the municipality, which has 36 wards.

Pipelines to cater to the basic needs of Kovilpatti residents would be connected from Seevalaperi, where water resources from the Tamirabarani, could be drawn at 52 kilometre distance.

Preliminary work commenced with the setting up of infiltration wells in Seevalaperi. Four infiltration wells would be established.

The project is planned to be completed in 18 months but the work would be expedited within 14 months, sources said. On completion of the project, people would have access to 19 MLD (Million Litres of water per Day).

The sources said that apart from the four existing tanks, 10 more would be set up and a booster station established at Ilavelankal.

A resolution for implementing the project was passed during 2006-11 in the Kovilpatti municipality, said K. Srinivasan, town secretary, CPI (M).

Eight major combined water supply schemes across the State will be completed in the next two years.

Moving the demand for grants concerning departments under his Ministry in the Assembly on Monday, Municipal Administration Minister K.P. Munusamy said the combined water supply schemes in Virudhunagar, Madurai and Sivagangai districts taken up at a total cost of Rs.3,276.62 crore were in various stages of completion. These projects, which would benefit 85 lakh people, would be completed between this fiscal and next financial year.

Tendering was in process for three other combined water supply schemes in Cuddalore, Pudukottai and Thanjavur at a cost of Rs.877.74 crore. Nearly 18 lakh people would receive water supply through these schemes.

This fiscal too, the government proposed to cover 6,000 rural habitations through individual power pump schemes and combined water supply projects for which Rs.1,190.72 crore had been allocated. The Tamil Nadu Water Supply and Drainage Board would also revamp infrastructure in combined water supply projects this fiscal. Nearly 626 works, including replacing aged pumpsets and damaged pipeline, would be taken up at a cost of Rs.58.44 crore, Mr. Munusamy said.

TWAD also proposed to provide safe drinking water to 2,887 more anganwadis across the State this year. It had already provided water supply to 5,211 anganwadis last year.

In a bid to augment groundwater sources in the water-starved districts, the State government planned to create 1,171 recharge structures, be it check dams or percolation ponds, worth Rs.60 crore.

The TWAD was planning to complete district-wise groundwater quality maps this financial year to help identify sources for water supply.
