Grande - Model TRU-BEND - Overflow Bending Weir System - Brochure

The TRU-BEND overflow weir system is designed to maintain maximum water levels before it overflows through the upstream, allowing full utilization of all available upstream storage volume without affecting overflow weir capacity in combined sewer overflow (CSO) applications. TRU-BEND`s unique and extensively tested design works by only allowing any excess water in the system to reach the receiving watercourse, but only after upstream water level has been reached. This increases the storage volume of tanks and sewers and reduces the frequency and volume of overflows, resulting in less water pollution. This enables the TRU-BEND to overcome the disadvantages inherent to fixed weirs. The TRU-BEND protects against backflow as it is normally in the closed position.
