Stage set for dry run of Narlapur pump of Palamuru Rangareddy Lift Irrigation Scheme on Sunday

HYDERABAD: Engineers have made all arrangements for a successful dry run of one pump at the Narlapur reservoir at Kollapur of Nagarkurool district under the multi-stage Palamuru Rangareddy Lift Irrigation Scheme (PRLIS).

The dry run will include running one pump at a time by switching on power. However, the wet run would take place after a fortnight.

Hamid Khan, Chief Engineer of PRLIS, has said that the TSTRANSCO and the project contractor Megha Engineering and Infrastructures Ltd (MEIL) have completed the preparatory work and are waiting for a go-ahead by the authorities. “The dry run will help the engineers to rectify any defects before switching on the second pump at the Narlapur reservoir, he said.

Meanwhile, work on a 2.75-km long canal to bring Srisailam backwaters to Narlapur was completed on a war footing. A head regulator was built at the gravity canal to send water to the surge pool through three tunnels. From the surge pool, the water would go to nine 145-MW capacity huge machines that would lift water to the Narlapur reservoir. Each machine could lift 0.25 TMC of water.

Preparations were also made to store 2 TMC of water in the Narlapur reservoir and then the water would be sent to the Yedula reservoir through a gravity canal and tunnel. A 400 kV sub-station was built to supply 127 MW power to each machine.
