ABSTRACT:
A system for controlling ground water level in a particular surrounding area is disclosed. In particular, a dewatering system to safeguard the integrity of an in-ground swimming pool against damage or disruption caused by excess water accumulating at or near the soil surrounding the swimming is described. Such contiguous ground water, when it rises to an undesirably high level, for example, such as at a level higher than the level of water in a swimming pool, as a consequence of the resulting hydrostatic pressure, will cause adverse effects. The invention provides a system for the removal of ground water accumulating in a given area in excess of a predetermined level, such as around a swimming pool, until the desired level is restored.
