  • a recirculating water supply system for swimming pools includes a perimeter drain gutter withadjustable skimmers; scuppers; and overflow lou-v vers at different levels controlling the amount and level of water in the pool and flowing into the gutter where it drains into a collection box which has a pump and filter connected thereto.
  • a surge tank may be provided connected to the collection box to accommodate sudden large pool water level variations. The filtered water is uniformly returned to the pool through nozzles spaced around the gutter perimeter.
  • the principal object of the invention is to provide a recirculating water supply system for swimming pools which provides an optimum flow of filtered water to a pool regardless ofthe number of persons using the pool to a predetermined maximum.
  • a further object of the invention is to provide a water supply system as aforesaid wherein overflow of the pool water at the pool perimeter at maximum bathing capacity is avoided.
