Mott’s Creek basin is one of the larger regional sewer basins in the Cape Fear Public Utilities Authority System. It receives wastewater from 13 tributary pump stations in the Monkey Junction area. Our Design-Build team is tasked to improve the pump station and collection system, which will provide increased capacity – from 1.76 MGD to 4.18 MGD. Adding to the complexity of the project is the need to keep the existing station operational and accessible for CFPUA staff during the construction of the new plant within the same footprint. Once the new pump station is constructed, activated and on line, the old will be demolished.
