The HydroLatch® Flood Gates provide reliable backflow and flood protection for sewer and stormwater systems. They close automatically when water flow reverses, effectively sealing off pipes to prevent flooding, contamination, and structural damage. Their passive design requires no external energy or manual intervention, making them ideal for critical infrastructure.
