ABSTRACT:
A swimming pool includes a swimming tank, which stores water for swimming; and an upstream tank, which stores water to be supplied into the swimming tank. The pool further includes a downstream tank, which stores the water streamed from the upstream tank through the swimming tank; and a pump, which forces the water stored in the downstream tank to the upstream tank. The water in the upstream tank has an energy head that is higher than the water in the swimming tank so as to generate water current in the swimming tank.
