水と砂の遊び場：手押しポンプ、水路、排水処理

Design a combined sand and water play zone for a Taiwanese park, planned around the practical problem of keeping the two from ruining each other. Compose a hand-operated pump on a stone plinth feeding a shallow cast channel that steps down through a series of small basins and gates before discharging into the sand pit at the lowest point. Set a linear drain and a gravel filter strip at the pit edge, and put a foot rinse and a bench just outside the wet zone. Let the channel be reachable from both standing height and a seated position.
