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 …
Effect of Impurities in Water on Properties of Concrete The impurities in water used for the preparation of concrete may affect the properties of concrete in the following way: a) The strength & durability of concrete may be reduced due to the presence of impurities in the mixing water. Experiments show that water containing an …
Role of Water in Concrete Water is the most important & least expensive ingredient of concrete.It plays an important role in mixing, laying, compaction, setting & hardening of concrete. The strength of concrete depends on the quality & quantity of water used in the mix. The functions of water in the concrete mix are given …
