What is Surge Pool?

  • Surge pool or tank is a water storage device used as pressure neutralizer in hydropower water conveyance system to resists excess pressure rise and pressure drop conditions.
  • It is a standpipe or storage reservoir at the downstream end of a closed aqueduct, feeder, dam, barrage pipe to absorb sudden rises of pressure, as well as to quickly provide extra water during a brief drop in pressure.

About the Kaleshwaram surge pool

  • Constructed on the hillocks on the outskirts of Thippapur village in Illanthakunta mandal, the surge pool measures 92 meters deep and 56 meters diameter and would store one tmc feet of water.
  • Water would be lifted by using four motors to the Ananthagiri Reservoir.
  • The water would reach the surge pool from Mid Manair Dam — Sri Raja Rajeshwara reservoir — by travelling 3.4 km through gravity canal and 7.6 km through tunnel.
  • Incidentally, the open-to-sky Surge pool was constructed in a record time of 13 months at a cost of ₹ 2,700 crore.
  • The four motors in this pool would use 106 MWs of power and accordingly a 440 KVA sub-station was constructed at the vicinity of the pool.
