Hyderabad: The State government has accorded administrative approval for lifting of 1 TMC of water per day for 60 days from the flood canal system in three stages to Sriram Sagar Project (SRSP) reservoir by strengthening the existing canals and vulnerable reaches at a cost of Rs 1067 crore.
These express instructions were given by the Chief Minster in view of the urgent necessity to irrigate 9.63 lakhs of acres of ayacut considering the reduced availability of water in the SRSP. The government order to this effect was issued on Saturday.
The Sriram Sagar project was constructed with the storage capacity of 112 TMC. At the time of formulating proposals in river Godavri the yield was assessed at 196 TMC ( 75 per cent dependability) and 12 TMC at Lower Manure Dam (LMD) thorough manure river thus taking the total to 208 TMC. However due to extreme situation the SRSP capacity presently stood at 80 TMC only.
To further compound the problem, the actual yield stood at 54 TMC at 75 per cent dependability in river Godavari as against the designed yield of 196 TMC at SRSP. This reduced TMC figure was arrived at after observing the inflows from the last 20 years.
To supplement the SRSP for stabilization of 9.73 lakh acres of ayacut ( upto KM115) more lift schemes and utilizations were contemplated and about 95 TMC of water is required to irrigate this ayacut.
Therefor the government proposed to lift 1 TMC for sixty days from Kaleshwaram lift irrigation scheme dropping point through flood flow canal by providing three small lifts (with 33 M total head) the GO explained that 40 acres of land has to be acquired additionally for construction of these three lifts at different locations.
The total cost worked out for lifting 1TMC per day was at Rs 1067 crore, the GO said.
