With 2.8 million residents, Miami-Dade county has roughly 30,000 backflow prevention devices—mechanical valves that prevent the reversal of water once it has passed through the device. Critical to providing clean and safe water, faulty backflow devices can contaminate the potable water supply. The Safe Drinking Water Act makes backflow prevention a critical component of every municipal water distribution system, and compliance is mandatory.
Like most counties, Miami-Dade requires certain water customers to install backflow prevention assemblies at their water service connections. Backflow devices are most common at hospitals, assisted living facilities, service stations, auto repair shops, and water customers with lawn irrigation systems. But it doesn’t stop just at installation. Juan Pelay, Chief Meter Operations & Maintenance for Miami-Dade county says, “Because the backflow preventer is a mechanical device with springs, moving parts, and rubber seating surfaces that wear over time, the devices need to be tested every year to ensure that the assembly is working properly.”
