SURE-BEND (hydraulically controlled flex weir) from Grande

The SURE-BEND Folding Weir increases storage capacity in CSO applications. Its hydraulic design maintains maximum upstream water levels, preventing overflow while reducing overflow frequency and volume. It releases excess water only once the upstream water level is reached, improving reservoir storage and reducing pollution. The SURE-BEND also prevents backflow by staying closed under normal conditions.

Key Features of the SURE-BEND Hydraulically Operated Folding Weir

• Positive Hydraulic Control: Precise water level management.
• No Lower Clearance Required: Operates without needing additional clearance.
• Maximized Storage: Increases upstream storage, reducing overflow.
• Adjustable: Performance levels are easily modifiable.
• Backflow Prevention: Stops backflow, maintaining clean water.
• Improved Hydraulic Quality: Enhances overflow system efficiency.
• Cost-Effective: Reduces storage tank construction costs.
• Modular and Adaptable: Easy to install in existing setups.
• Stainless Steel: Provides long-lasting durability.

The SURE-BEND Folding Weir is installed along the entire length of the weir opening, pivoting at the bottom and opening at the top. The system uses hydraulic cylinders to adjust the water levels, ensuring precise and efficient control. In the event of a power loss, the SURE-BEND continues to function as an emergency overflow, ensuring reliable performance under all conditions. The system continuously monitors upstream and downstream water levels, making real-time adjustments to maintain optimal performance and prevent overflows. Available in models from GSB-30 (12 inches of water storage) to GSB-100 (40 inches of water storage), the SURE-BEND can handle a wide range of applications. Its maximum length can reach up to 20 feet (6 meters), allowing it to accommodate various weir sizes and configurations.
