Domestic water supply system

Domestic water supply systems serve to supply individual residential houses or farms with water sourced from a well of adequate yield on the premises.

They can also be used for fire protection, cooling circuits, general and spray irrigation, drawdown of ground water levels, pressure boosting, fountains and air-conditioning systems.

Domestic water supply systems are equipped with either horizontal pumps or vertical pumps. The pumps must be fitted with a foot valve in the suction line. Exceptions to this rule are submersible borehole pumps, which are suspended beneath the lowest water level.
