Surge tank or surge tower operation benefits in three different ways. 1. It shortens the distance between the turbine inlet andthe nearest free water surface, and thereby greatly reduces the intensity of the water hammer waves. 2. With a reduction of turbineload, the water level in the chamber rises until it exceeds the level in the mainreservoir, thus retarding themain conduit flow and absorbing the surplus kineticenergy. 3. In case of increase of turbine load, the chamber actas a reservoir which will provide sufficient water to enable the turbine to pick up their new load safely and quickly and to keep them running at the increased loaduntil the water level in the surge chamber has fallen below its original level. Sufficient head is thereby created to accelerate the flowof water in the conduit until itmeets the new demand. via Ghulam Nabi1, Habib-ur-Rehman2, Muhammad Kashif 3 and Muhammad Tariq4 1 Assistant Professor Centerof Excellence in Water Resources Engineering, University of Engineering andTechnology, Lahore. 2 Professor Department of Civil Engineering, University of Engineering and Technology, Lahore. 3.
