FRESH WATER PUMPS AND IT`S STATIONS

Water pumping • The pumping of water is a basic and practical technique, far more practical than scooping it up with one's hands or lifting it in a hand-held bucket. This is true whether the water is drawn from a fresh source, moved to a needed location, purified, or used for irrigation, washing, or sewage treatment, or for evacuating water from an undesirable location. • A fresh water source in a lower stream, river, pond, or lake is often pumped to higher ground for irrigation, livestock, cooking, cleaning or other uses by humans, who quite naturally need fresh water. This will purify mostly fresh water, and the treatment of largely contaminated water refer endlessly to pumping.

Water pumps types 1 -Direct lift pumps. • 2 -Displacement pumps. • 3 -velocity pumps. •

Water Pumping Station * Pumping stations are facilities including pumps and equipment for pumping fluids from one place to another.

Common types of pump 1 -The vertical turbine pump (line shaft and submersible types) 2 -The centrifugal horizontal or vertical split case pump designed for water-works Service.

Pump Discharge Capacity 1 -If the pump is used directly to supply water without a reservoir, the capacity must be equal to the peak hour demand. 2 -If the water distribution system has a reservoir, the pump capacity must be equal to the maximum daily demand.

Pump Selection 1 -If the pumping water level is less than 6 metres, use a centrifugal pump (maximum suction lift = 6 metres). 2 -If the pumping water level is from 6 -20 metres, use jet pumps or a submersible. 3 -If the PWL is greater than 20 metres, use a submersible or a vertical line shaft turbine pump.

Cost Considerations • 1_the construction and installation costs are high. Therefore, the whole system is rather expensive and only sustainable if operation and maintenance can be ensured. 2_The energy cost is one of the largest components in the water supply system. • 3_ it is very important that the degree of efficiency of the pumps is very high.
