AURANGABAD: With only 6.44% live water storage in Jayakwadi dam and increasing evaporation due to rise in temperature, the dam is expected to touch the dead storage by June 30. Irrigation department officials have assured that sufficient water is being reserved for drinking water needs of the city and region till July.

The current water stock at Jayakwadi dam might cater to the city’s need for another 40 days from its live storage. The irrigation officials said they expected the water levels to rise by the end of July. The dam water meets the industrial and domestic needs of the region including Waluj, Paithan MIDC, Jalna, Aurangabad, Ganagapur and around 200 villages.

Around 0.15 to 0.18 million metric cube (mm3) of water is being discharged daily from the dam to Aurangabad city alone. The Aurangabad Municipal Corporation (AMC) lifts around 150 million litres water a day from the dam.

The soaring temperatures have pushed up the evaporation rate by seven times in the last one week. “Evaporation loss recorded on Friday was 0.46mm3, while on Sunday was 0.73mm3. It jumped to 1.26 mm3 on Monday,” said the official, adding that the evaporation loss reduces in June once the monsoon sets in.

“The safe level of lifting water through pumps and machinery installed by the AMC is 453.5m. The water level in the Jayakwadi at present has reached to 456.39m on Monday,” said a Command Area Development Authority (CADA) official.

When the Marathwada region witnessed one of the worst droughts in 2012, the AMC officials had implemented remedial measures to lift water from dead storage by constructing a new approach canal and desilted the jackwell (the water lifting point) at the reservoir, which had paved the way for the municipal body to draw water up to 452.5m from the dam.
