McAlpine Creek Wastewater Management Facility Waste Activated Sludge Equalization and Blending and Odor Control Improvements

The Waste Activated Sludge (WAS) Equalization and Blending and Odor Control Improvements Project includes upgrades to several facilities at the McAlpine Creek Wastewater Management Facility (WWMF). Primary components include construction of a new cast in place concrete WAS equalization structure with multiple tanks/cells with mixers and pumps to allow for equalization and blending of WAS from the McAlpine Creek WWMF, Sugar Creek Wastewater Treatment Plant (WWTP) and in the future the Irwin Creek WWTP. Adjacent to this structure is a blending basin pump station which will convey blended WAS to the existing solids treatment process and in the future to the planned Thermal Hydrolysis Process. In addition, the project includes a new wet scrubber chemical odor control system for the Screening and Grit Facility, new duct work to this system from the south plant primary clarifiers and gravity thickeners as well as the rehabilitation of the Consolidated Influent Pump Station (CIPS) odor scrubber system.
