How do splash pads work?

Splash pads operate on two main system types. Flow-through (single-pass) designs pull water from the municipal supply, push it through ground sprays and overhead features, then drain it once — often into landscape irrigation or a stormwater system. They use more water but require less mechanical equipment and have fewer health concerns. Recirculating designs collect water in an underground tank, pass it through filters, dose it with chlorine (and sometimes UV), and pump it back to the features. They use far less water but need careful maintenance to stay safe. Most pads activate automatically during operating hours, run on a fixed cycle (15-30 minutes), or use a big push button that triggers a 2-5 minute spray. Underneath the colorful surface is a network of PVC pipes, solenoid valves, and a control panel — surprisingly mechanical for something that looks like a toy.
