The water park assembly includes a plurality of couplings with fittings for connection with an external water system. A box is matable with a waterline for connecting a thru-wall skimmer thereto, and an outlet is formed within one of the couplings. Fittings are formed within an inner wall of the coupling, and water jet nozzles are anchored thereto. Light illuminating sources are anchored within the fittings. Selected couplings have a handle attached thereto. At least one wheel is connected to an associated one of the couplings. Each of the couplings includes holes for anchoring coupling arches. The ends of the couplings have vertical grooves and attachment holes formed therein for receiving supports, wheels, handles and waterfall decorations. A slot is formed in the couplings for a rupture gate. The gate includes cross bars supporting the gate to an associated one of the couplings.
