How do splash pads prevent bacteria?

Bacteria control at splash pads depends on the system type. Recirculating pads run multi-stage treatment. First, mechanical filtration removes particles down to 10-30 microns. Second, primary disinfection uses chlorine or bromine maintained at 1-3 ppm to oxidize organic matter and kill most bacteria. Third, secondary disinfection — UV light or ozone — handles chlorine-resistant pathogens like Cryptosporidium and Giardia, which is required by many state health codes. Fourth, operators monitor water chemistry multiple times daily and shock-treat after fecal incidents. Flow-through pads rely on the city potable supply already treated to drinking-water standards, plus optional booster chlorination at the pad. Daily and weekly inspection by trained operators, posted by health departments, is the final layer that keeps the system honest.
