Water leaks cost state Rs 21 lakh per day, says Ramkrishna ‘Sudin’ Dhavalikar

PANAJI: The state pegs its losses due to leakage at Rs 21 lakh per day, PWD minister Ramkrishna ‘Sudin’ said. Deficiencies in the supply network are resulting in 25-35% leakage losses presently, which the department intends to reduce to 15%, he said.

“We don’t have exact quantities of our non-revenue water,” Dhavalikar said. However, as per our estimate, the loss on manufacturing water is Rs 21 lakh per day and that due to undercharging consumers is Rs 5.6 lakh per day (as per the average rate of water supply), he said.

Initially, this non-revenue water accounted for 40% of the department’s supply, Dhavalikar said. The government brought this figure down with the help of JICA, he said.

“In the next five years our aim is to bring it to less than 15%, with an immediate target of 20%,” Dhavalikar said.

JICA will provide us technical support to achieve it till 2019, he said.

Non-revenue water is water that has been produced and is “lost” before it reaches the customer either by way of leakage or by way of theft or metering inaccuracies.

The minister said most pipelines are either of cement or PVC and of diameters lesser than required.

In its target to reduces losses, the PWD, depending on demand, will upgrade old pipelines and increase their diameter, he said, adding the exercise will be carried out in urban areas.

Dhavalikar said his department is spending around Rs 1,000 crore to improve the water supply infrastructure in the state, including setting up of new water treatment plants and upgrading existing plants.

The 27 MLD water treatment plant at Opa will be completed by December-end and it will supply water to Ponda and Tiswadi, the PWD minister said. The 25 MLD water treatment plant, whose construction was delayed, will be taken up shortly as the department has got forest and environmental clearances, he said.

He said the department will take up a 5 MLD project, one each at Canacona, and Kale. Preliminary estimates for the Canacona and Sanguem projects are complete, Dhavalikar said, adding work on the plants will commence by December.

A new pipeline worth Rs 23 crore will be put in place to supply water to Netravali from the Sanguem plant, he said.

The PWD has carried out preliminary estimates for a 20 MLD water plant at Porvorim and the tender for the plant will be opened next month. The total cost of the project is Rs 30 crore.
