EXPOSED WATER SYSTEMS FROM EDUCATIONAL SIDE (TOP) SHOWING UNTREATED CISTERN PUMP 2, water system manifold 1, and untreated cistern, and systems from exit side (bottom) showing the diatomaceous earth filter, manifold 2, the chlorinator, the uv sterilizer (behind the chlorinator and cistern), treated cistern and manifold 3 with flexible tubing.

Educational Diagram

image 2

Educational diagram (actual decal on next to the exit stair) explaining to children how the closed loop water filtration system works.  The diagram illustrates the circulation of water as it goes into the slide where it becomes "black water" through bodily contact with children.  The water then enters the zero depth catch basin where it is drained and pumped to the untreated cistern where it is stored.  From the untreated cistern the water is pumped to the diatomaceous earth filter, the first process in filtering the water through the use of particle filtration, and then to the UV sterilizer where any bacteria and micro-organisms are sterilized.  There is a chlorine generator for the addition of chlorine increasing the water's safety for public use, the water is then stored in the treated cistern where it is pumped back up to the slide for use once again.
