| The Poringalkuthu reservoir is created by constructing a dam across Chalakudy river. The inflow of Poringalkuthu reservoir is contributed partly from the tail water of upstream Sholayar HEP. In addition, the reservoir receives water from catchments downstream of Parambikulam and Thunakadavu dams of PAP Project. The spill waters of above dams also flow to this reservoir. The water from Poringalkuthu reservoir is diverted through a water conductor system to two Powerhouses of Poringalkuthu Hydro Electric Project (PHEP) & Porigalkuthu left bank Extension scheme located on the left bank of Chalakudy river. After generating power, the water is released to Chalakudy river itself. |
