Vault-mounted feature
Definition
A splash pad water feature anchored to a below-grade concrete vault that houses its plumbing, valves, and electrical, allowing tall above-grade structures to attach securely.
Vault-mounted features include arch sprayers, misting towers, water cannons and themed structures — anything tall enough to need real anchoring. The below-grade vault holds isolation valves, so a single broken feature can be shut off without draining the whole pad.
Vaults are typically 3–4 feet deep with a watertight access lid. Operators check them weekly for leaks and pump pit water out as needed during heavy rain.
