Pumping Stations in a Water Distribution System

Site of The Pumping StationSetting Up The PumpsPiping and ValvesSizing of Units and Standby CapacityThe site of the pumping station primarily depends on the location of the water source and the place it has to be supplied. In addition to this, the following factors should be considered: 1. The site of the pumping station must be far away from any sources of pollution and contamination. 2. The elevation of the site should be higher than the highest flood level of the river or the water source. 3. If the source is a river, the site of the pumping station should be such that the machinery setup is capable of drawing adequate water to meet the peak demand at the busiest time of the day. This requires an exhaustive study on parameters such as a change in river course, dry weather flow, etc. 4. The site should permit future expansion and growth. 5. Possibilities and risks of a fire hazard for the site should be as minimal as possible. 6. The proximity of the location with the nearest power station, railway station, etc. should be considered.
