CALIBRATION OF A WATER DISTRIBUTION SYSTEM – A CASE STUDY

Water is the foundation of life. Moving water from the source to the customer's needs a network of pipes, pumps, valves, and other accessories. Storing water to accommodate fluctuations in demand attributable to variable rates of usage or fire protection needs storage facilities like tanks and reservoirs. Piping, storage, and supporting infrastructure are together called as the water distribution system (WDS). The WDS plays a crucial role in transporting water to cities, homes, schools, hospitals, industries and other facilities. The primary function of water distribution system is to transfer water from treatment facility to end users. The distribution system should also provide adequate and reliable water to customer. Usually, water consumption varies with time and follows a diurnal pattern. This means the demand of water is less during the night time, goes on increasing during the initial hours of a day, then the demand drops during the afternoon time and finally in evening, the demand rises again.
