The SURE-BEND Hydraulically Operated Bending Weir System is designed to maintain maximum water levels upstream of the weir thus allowing full usage of all the available upstream storage volume while not adversely affecting the overflow weir capacity in Combined Sewer Overflow (CSO) applications. The SURE-BEND’s unique and extensively tested design operates by only allowing any excess water in the system to reach the receiving stream but only after the design upstream water level is reached. This increases the tank and sewer storage volume and reduces the frequency and volume of overflow events, resulting in a decrease in water pollution. This allows the SURE-BEND to overcome the fixed weir’s inherent disadvantages. The SURE-BEND protects against backflow as it is normally in the closed position.
The SURE-BEND allows for installation in new overflow structures or can be retrofitted directly over existing fixed weirs. The following components are required and included in the SURE-BEND Hydraulically Operated Bending Weir System: the bending weir flap, the sleeve bearings, the supports, the guide walls, the anchoring system, the hydraulic cylinder, the hydraulic power unit, the control panel, the ultra-sonic water level sensor and the inclinometer.
