How does real-time leak detection work on splash pads?
Quick answer
Real-time leak detection compares supply-side flow against expected jet output and triggers an alert when the gap exceeds a threshold. Some installs add acoustic sensors on supply lines that listen for the high-frequency hiss of a pinhole leak. Catches leaks within hours instead of months.
Leaks are the silent budget-killer for splash pad operators — a pinhole in a buried supply line can dump 10,000 gallons over a week before anyone notices. Real-time leak detection works two ways. The first is flow accounting: the smart-flow controller compares supply-side magnetic flow meter readings against the expected jet output for the current run cycle. A consistent gap of more than 3-5% triggers an alert. The second is acoustic: small piezoelectric sensors clamped to supply lines pick up the high-frequency hiss of pressurized water escaping through a pinhole and triangulate location to within a few feet. Combined, the two systems catch leaks within hours. Cost: $3K-10K added to a smart-flow install. Particularly valuable in arid regions where water rates are high (Arizona, Nevada) and on older recirculating pads with aging copper supply lines.
