Pumping stations are either as in-line for lifting the sewage from a deeper sewer to a shallow sewer or for pumping to the STP or the out fall. They are required where low lying development areas cannot be drained by gravity to existing sewerage infrastructure, and/or where development areas are too far away from available sewerage infrastructure to be linked by gravity.

Even if the water source for your small water system is of pristine quality, if the distribution system is not maintained or is in a state of disrepair, the quality of water may deteriorate before it reaches the customer.

Wet soft spots on unpaved ground, grasses, emergence of springs at odd places indicates leakage from underground pipes, Such indications will be available when pipes are laid below loamy or clayey soils, However, direct observation is difficult in sandy soils.

Storage Resevoirs - store the treated water until it is pumped into the service reservoir or distribution reservoirs. The capacity of storage reservoirs should be 14 to 16 hours of average daily flow.
