Integrated System Provides Temporary Bypass At Colorado Treatment Plant

Custom-designed solution offered project team remote bypass control and monitoring

In Colorado, the project team for an expansion and renovation of a wastewater treatment plant was in need of a bypass system to move a peak flow of 128 million gallons per day. Wagner Rents, the rental arm of Wagner Equipment and Xylem’s Godwin and Flygt distributor in Colorado was named the bypass contractor for this portion of the job. Wagner Rents pump team worked with Xylem to design and install a temporary system to convey the full amount of flow. The solution that followed also provided the treatment plant with the ability to integrate the temporary bypass into its SCADA system and to log the data as if it was its own permanent pumping system.

“The project specifications were fairly open, but what we needed to do was take the influent flow from the headworks, after it went to the primary clarifiers, to the aeration basin,” said Clyde Refvem, Pump Specialist for Wagner Rents. The ultimate need was for a pumping bypass system that was capable of handling at least 64 MGD as well as an additional 64 MGD for high-flow conditions and backup pumping, totaling a max flow capacity of 128 MGD.
