Combined Gravity And Pumping System In this system, the treated water is pumped and stored in an elevated reservoir, from where it is supplied to the consumer by the action of gravity. Thus, this method combines pumping as well as gravity flow. This system is fairly reliable. Read more: Function of Storage Reservoir 3…
5 Function Of Storage Reservoir The storage reservoirs are generally provided in the distribution system to store clear treated water before it is distributed to the consumer. Following 5 functions of the storage reservoir are: 1. They help the pump to run at a uniform rate. 2. They provide the facility of storage of…
Testing of leakage of Sewer Pipe Joints The leakage in the pipe joints or any other points is tested by water test or air test. a) Water Test This test is carried out between two manholes. The lower end of the sewer line is provided with a plug and the upper is kept open. In the…
