CHENNAI: With the city receiving a steady inflow from the Kandaleru reservoir in Andhra Pradesh, Chennai Metrowater is confident of meeting the demand for water during summer months.

The reservoir at Poondi, which is the prime storage point for the city, has realised 1.33 thousand million cubic feet (tmcft) of water since last month when the water supply from the neighbouring State was resumed.

The combined storage of the four reservoirs from where the city gets its supply — Poondi, Cholavaram, Red Hills and Chembarambakkam –— was 6.9 tmcft on Wednesday.

During the corresponding period last year, the storage level was 8.5 tmcft.

Officials of Metrowater said though the water availability in the city reservoirs was relatively less this year, the shortfall has been met with the resources from Veeranam tank.

The water agency had reduced the supply from 640 million litres a day (mld) to 570 mld since January this year to save resources for summer months.

“We expect at least 2.5 tmcft of water to be released till April from Andhra Pradesh. The water supply from Veeranam tank could be sustained for three months,” said an official.

With the available resources, consumers would be given daily water supply till November.

This could be ensured despite the estimated evaporation loss of nearly 40 per cent during the next two months.

If required, water would be purchased from about 100 private agricultural wells in Tiruvallur district.

About four lakh litres of water would be drawn daily from each well at the rate of Rs.24 per hour.

Similarly, about 40 million litres would be extracted from the borewells at Neyveli aquifers, which have remained unused for several months now, whenever there is a need, the official said.
