Our preschool is currently trying to put together an interactive water feature for our playground. We want something that will recirculate water through the day, is 'child powered' (hand pumped), and can be dumped out at the end of the day (to comply with local laws). We want the water to be zero depth, but also forceful enough so the children can maneuver the water with sticks, rocks, pebbles, etc. A "dry river bed" idea, but with some water flow. We've had two landscaping companies come out to bid, but I am short on ideas as to how to make this work. Here are a few photos we showed them. Does anyone have ANY photos or ideas on how to make this work? We would LOVE your input! Something like this could work...if we could just get the water to recirculate during play & then dump out at the end of the day. This would be perfect, except California has a "no standing water" rule. Cute! Too deep for our purposes, but I love the way it looks like a real creek. I also love the little hand pump! This feature is at a local park in Pasadena. With the laws on "fall zones," I like that this feature wouldn't require the kids to climb on it. But then again, climbing through a river bed is half the fun!
