(54) Swimming pool


(57) A swimming pool has means for directing a jet of water (J) across the water surface towards a side of the pool to form a counter current (C) against a swimmer, and means for relieving back-pressure at the downstream end of the counter current. The means for relieving back-pressure may comprises a weir (3) over which the jet of water flows. A conduit defines a return flow path (4), and extends towards the upstream end of the jet (J) to facilitate flow of water back towards a pump (1) at the upstream end of the jet. A discrete water level below the water lever in the main body of the pool may be defined by water on the far side of the weir (3). In a variant, a downward transition in water level from the water in the main body of the pool may be provided by water flowing smoothly over the weir (3).
