Water levels in Nagarjunasagar reservoir, considered as the lifeline for several districts including Hyderabad in the State, have come down drastically. If the levels go down beyond the minimum draw down level, drinking water supply to Hyderabad and its suburbs will be hit.
The current water level in the reservoir is 503 ft which is at its lowest in recent years. At this level the water can be drawn only for two or three more days. However, officials are now trying to run emergency motors to lift water and pump it into supply chain to ensure uninterrupted drinking water for twin cities. There is a shortage of 100 tmcft of water in the reservoir when compared to that of last year's.
The Nagarjunasagar dam, an 11,472 million cubic metres reservoir, serves as one of the primary irrigation and hydroelectric projects. Besides providing water for irrigation Nagarjuna reservoir also caters the daily water needs in city. The state government seems to have exhausted all water for irrigation and power generation.
The water levels in the dam now stand at 194.33 tmcft as against 234.10 tmcft this day last year. There is no water available in the reservoir for irrigation, according to the officials from Hyderabad Metropolitan Water Supply and Sewerage Board.
"The water level in the reservoir has decreased to 503 ft due to which as of now we have stop catering water for irrigation. However, there is no problem as far as supplies for drinking are concerned. As of now 1.5tmcft water is stored in Akkampalli reservoir, from which water is drawn for twin cities. Hyderabad also gets water from Singur, said G Rameshwar Rao, chief general manager, transmission circle, HMWSSB.
Though the Rabi season has come to a close, water will be required for filling of drinking water tanks in Guntur, Eluru, Machilipatnam, Gudivada and hundreds of villages in Krishna delta, before the summer is over. There is 194.33 tmcft water in Nagarjuna reservoir which can be pumped using lifts in case of an emergency.
