Northwest Wastewater Treatment Plant Improvements

The Northwest Water Reclamation Plant is one of the City’s only means of treating domestic and industrial wastewater before discharging effluent and thus needed improvements to continue its operation. The project included reconstruction of the existing traveling bridge sand filters to cloth media traveling bridge filters, demolition of existing equipment, installing the new cloth media traveling bridge equipment, all new electrical, new instrumentation, and a canopy to cover the filter bays with the new equipment. Work also included removing and replacing the odor control chemical system and associated piping with a temporary system set up during construction.
