Northwest Regional Water Reclamation Facility Expansion

The Northwest Hillsborough Wastewater Consolidation Program was approved by the Hillsborough County Board of County Commissioners in 2014 as part of its Capital Improvement Program. The program retires two aging wastewater plants and consolidates treatment at the Northwest Regional Water Reclamation Facility (NWRWRF). Overall, the program improves wastewater service in Northwest Hillsborough County, improves reliability, and saves money for all County customers. Garney served as Design-Builder responsible for preconstruction, construction, and public outreach for the NWRWRF and the River Oaks Diversion Project.

The NWRWRF was expanded from 10 million gallons per day (MGD) to 30 MGD. Garney, in a joint venture with Wharton Smith, constructed significant improvements to technologies to efficiently control odor and noise, including sodium hypochlorite chemical feed facilities, aeration, four 130’ diameter secondary clarifiers, two D110 Type II concrete water storage tanks, conventional media filtration, grit facilities, a headworks, concrete equalization basins, and an odor control system. During preconstruction, Garney developed a number of innovative ideas and cost-saving recommendations contributing to $11.7 million in value engineering (VE) savings.
