Installation of water pump is very easy, any certified plumber and electrician can install electric water pump. Your question maybe is, how to design water pump water system to service the community? To determine the correct rating of water pump to be used and to design a water system, here are the steps : 1) Determine the safe discharge yield of your well for your water source, by series of tests. This will enable you to know discharge rate of well and the draw back time of water after pumping. This data will be used for designing a pump (its discharge capacity). Note that pump discharge capacity should be lower than well safe yield capacity in order not to drain the well. 2) Determine the suction lift or height of water table in the well by measuring the height from water table up to the top of the well. This data will be used for pump design (its suction lift/height capacity). Pumps suction lift varies depends on its Horsepower capacity and the type of pump (submersibble or centrifugal). 3) Determine number of households in the community. This data will be used for the design of reservoir (tank) for your water system and the number of hours for the pump to operate to fill the tank. Note that the average usage of water is 120 liters per day per capita. So the more the number of population, the bigger the tank and the longer the pumping time in order to meet the per capita usage. 4) Determine the elevations from your water source towards the community to be served. Use survey instrument to determine the elevations. This data will be used to design a height of the tank and the sizes of service pipes towards the community. The higher the difference in elevation from your source towards community, the lower the height of the tank and the smaller the sizes of service pipes. Sizes of service pipes can be determined by hydraulic heads (heights). By following these steps, I gues you can now design and construct a water system.
