The Stowe Regional Water Resource Recovery Facility (RWRRF) is a regional approach to wastewater treatment serving western Mecklenburg County and Eastern Gaston County. Crowder-Garney-Hazen is leading this design-build project. F&R worked with Hazen & Sawyer to develop the design.

This 79-acre facility is designed to replace a total of three wastewater treatment plants located along the Catawba River. The project includes a new pumping station and a new treatment facility with a capacity of 15-million-gallons-per-day (GPD), which provides room for future expansion. The facility’s treatment process will include flow-through primary clarifiers, Biological Nutrient Removal (BNR) tanks, secondary clarifiers, deep-bed filters, UV disinfection, and post-aeration tanks. A 60-inch diameter pipe will discharge effluent from the facility into an outfall in the Catawba River. Additional structures include multiple distribution boxes, storage buildings, holding tanks, an administrative building, and a boat dock on the Catawba River. Multiple driveways are planned throughout the facility to connect to new entrance roads. Stormwater Best Management Practices (BMP) are planned on the facility’s south side, with an outfall pipe discharging near Long Creek.

F&R was the Geotechnical Engineer-of-Record, providing geotechnical design support in coordination with the Hazen & Sawyer team; the Geotechnical services have been completed. F&R is providing ongoing support related to construction materials testing and special inspections activities. The Special inspections are being performed as required by the State of North Carolina building code and Mecklenburg County Special Inspections (Meck-SI).
