摘要

A recirculating water supply system for swimming pools is provided which includes, around a pool, a perimeter drain gutter with adjustable scuppers, skimmers and overflow louvers in communication with the gutter. A collection box is attached to the drain gutter with connections to a pump and filter to return the filtered water to the pool uniformly through nozzles spaced around the gutter. The system may be provided with an optional surge tank connected to the collection box providing storage space to compensate for sudden water level variations in the pool.
