Krishna Water Crosses Border
Krishna water from Andhra Pradesh is needed to help meet the city’s water requirement during the summer months
By the time you read this, Krishna water from Andhra Pradesh would have reached the state and be on its way to the city's reservoirs. The water that was released almost a fortnight ago was expected to reach the city in the early hours of Saturday.
A team of Water Resources Department (WRD) officials are camping at Uthukottai, Tiruvallur district, where the entry point of the 152-km long Kandaleru Poondi canal in the State is located. The water discharged from the Kandaleru reservoir had reached 147 km around 9 p.m. on Friday.
It covers about 500 metres to one km in an hour. As only a small volume was flowing into the dry canal bed, the Krishna water took many hours to cover the distance, said WRD officials.
The damages in a siphon over the canal at Ubbalamadugu near Varadapalayam also contributed to the delay. “We are monitoring the flow of water near the stretch where temporary repair works were carried out recently,” said an official.
Meanwhile, the Andhra Pradesh authorities stepped up the water discharge to 1,000 cubic feet per second on Friday. It is being released exclusively for the city, this time, and the regulators located midway at Tirupati and Kalahasti have been closed.
From the entry point, Krishna water is expected to cover the 25-km stretch between Uthukottai and Poondi reservoir in a day as the canal bed is uniform. This will ensure faster flow.
The repair works, such as construction of concrete lining wall along the canal, were suspended to facilitate free flow in the canal.
Krishna water will help to fill the gap in storage at the city's four reservoirs. They have a combined storage of 4.6 thousand million cubic feet (tmcft) against the total capacity of 11 tmcft.
Chennai Metrowater, on an average, draws one tmcft every month from the reservoirs to supply to the city. If the four tmcft of water, which is the assured quantum by Andhra Pradesh government under the Krishna Water Supply project for the summer period, is realised, it will meet the demand for four months. The water agency now provides about 830 million litres of water daily.
