The TRU-BEND Overflow 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 TRU-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 TRU-BEND to overcome the fixed weir’s inherent disadvantages. The TRU-BEND protects against backflow as it is normally in the closed position.
The TRU-BEND allows for installation in new overflow structures or can be retrofitted directly over existing fixed weirs. The following components are included in the TRU-BEND Overflow Bending Weir System: the bending weir flap, the sleeve bearings, the supports, the guide walls, the anchoring system, the counterweight system and the inclinometer.
