How are splash pads built?

Splash pad construction follows a clear sequence. First, site work: excavation, grading, and rough plumbing layout. Second, the underground systems — surge tank, drainage piping, chemical and electrical conduits — go in below grade. Third, the slab is formed and poured with a slight slope toward drains, with jet stubs cast into the concrete at exact locations. Fourth, surface finishes (broom finish, decorative stamp, or rubberized topping) are applied. Fifth, spray features are bolted on and connected. Sixth, the equipment room — pumps, filters, disinfection, controls — is wired and plumbed. Finally, commissioning: pressure tests, chemistry calibration, feature testing, and inspection by health and building authorities. Total project costs run $200,000 for small toddler pads to over $1,000,000 for large interactive installations with dozens of features and elaborate theming.
