Where the days mechanism starts with water coming from river and through high level reservoir, The flow generates electricity and collected at power station for further dismission night mechanism starts with pumping the water from low-level reservoir with the help turbine to high level reservoir

Coming to details the water is being collected of the high-level reservoir from river. After that the water flow through the gates of dam. Moreover, the speed of water flow generates the electricity. Therefore, the resultant electricity is being stored of power statin and the water is being carried by reservable turners to the low-level reservoir. from power station the collected electricity has been transferred through power lines to natural gride.

The night mechanism totally opposite. Where the reservable turbines pumping the water from low -level reservoir to high-level. Reservoir trough pipes. Moreover, the intake point is closed at night.
