TRU-FLAP Floating Gate from Grande

The TRU-FLAP Floating Gate is designed to prevent flooding and backflow caused by high downstream water levels. It acts as a floating weir with an automatically adjusting crest elevation, making it ideal for CSO, SSO, and overflow systems. The system prevents overloading of sewer systems and treatment plants, reduces pumping costs, and improves wastewater treatment efficiency.

Key Features of the TRU-FLAP Floating Gate System

• Up to 4 feet (1.2 m) Headroom: Suitable for installations requiring significant vertical clearance.
• Modular Construction: Extends up to 20 feet (6 m) for flexibility in varying system sizes.
• Hydraulically Ideal Shape: Designed to minimize hydraulic resistance, ensuring efficient flow.
• Shutter Open in Rest Position: Allows overflow to pass unimpeded during normal conditions.
• Minimal Rise for Adjustment: Increases with minimal rise in downstream water level, preventing backflow efficiently.
• Low Hydraulic Resistance: Ensures smooth water flow with minimal energy loss.
• Easy Installation: Adaptable to existing installations, making retrofitting quick and cost-effective.
• Stainless Steel Construction: Durable and corrosion-resistant for long-lasting reliability.

How it Works

The TRU-FLAP Floating Gate consists of a stainless steel pivoting flap mounted on a weir. In its resting position, the flap hangs down, allowing water to flow over the crest freely. As the downstream water level rises, the flap pivots upwards, establishing a new weir height and preventing backflow into the system. The system’s lightweight design ensures quick responsiveness to small changes in water levels while maintaining structural stability under high downstream pressures.

The TRU-FLAP can also be sealed on all four sides to prevent backflow if the downstream water level exceeds the flap height.
