State may write to A.P. seeking release of Krishna water

CHENNAI: Water from the Kandaleru reservoir in Andhra Pradesh is likely to be released next month, for the second time this year, to augment the city’s water supply.

With the level in the city reservoirs depleting, the Tamil Nadu government plans to write to the Andhra Pradesh government within a few days seeking the release of Krishna water for Chennai.

As per the 1983 agreement between the two States, water has to be released to Tamil Nadu twice a year — between January and April and between July and October.

Officials of the Water Resources Department (WRD) said that the work of repairing various stretches in the 25-km-long Kandaleru Poondi canal in Tamil Nadu limits had been completed.

The Satya Sai Trust took up the project to construct retaining walls along the bund on various damaged stretches totalling 300 metres between the 14-km point and the 20-km point of the canal. This would prevent earth from the bund caving into the canal bed during the monsoon.

Moreover, stone pitching on the slope above the canal was also carried out in the vulnerable portions between 12 km and 22 km of the canal. Measures have been taken to reduce water loss, the officials said.

Metrowater officials said that the storage level in the city reservoirs was sufficient to meet the city’s demand till the onset of the northeast monsoon.

At present, the water storage in the four reservoirs was 6.1 thousand million cubic feet (tmcft) against the cumulative capacity of 11 tmcft. In June last year, the total storage was 6.2 tmcft.

Metrowater offsets the loss on account of the Veeranam tank turning dry by drawing more water from the reservoirs in Red Hills and Chembarambakkam, besides using well fields and the Neyveli aquifer.

Water from the Kandaleru reservoir would help in easing the situation and continuing with the daily supply of 650 million litres a day to the city’s residents, the officials said.

WRD officials said the storage at the Kandaleru reservoir is 24 tmcft as against the capacity of 68 tmcft.

Since 1996, the city has received 39 tmcft of water from Andhra Pradesh.

The entry point of the Kandaleru-Poondi canal in Tamil Nadu limits realised 2.7 tmcft of water when water was released between January and April this year, the officials added.
