    Abstract: A method of operating a swimming pool with a circulating water flow. The method including the steps of discharging a jet of water and splitting the flow of water. The discharging step including the discharging of a jet of water from an outlet at a head end of the swimming pool into a swimming compartment, whereby the jet of water flows in a primary flow path toward a foot end of the swimming compartment. The splitting step including the splitting of the flow of water to define two circuitous flow paths, each said flow path having a return flow path flowing within said swimming compartment in a direction generally opposite to said primary flow path back toward said head end.

  • Patent number: 9428928
    Abstract: A swimming pool with a circulating water flow includes a plurality of side walls adjacent a swimming compartment, one of the side walls including an outlet, at least one inlet positioned below and at a lateral side of the outlet, and a plenum arrangement on a side of the one wall opposite the swimming compartment. The plenum arrangement is in communication with each inlet and the outlet. A water propulsion device is positioned within the plenum arrangement and effects a pair of circuitous water flow paths within the swimming compartment. The swimming pool having an absence of a separate return flow plenum arrangement extending along the length of the swimming compartment.
