Population growth and economic development projections through 2050 have led the Fulton County Department of Public Works in Georgia to expand and upgrade its Big Creek Water Reclamation Facility (WRF). This facility, serving a 70-square-mile area in the northern part of the County, will be expanded from 24 million gallons per day (MGD) to 32 MGD using state-of-the-art membrane bioreactor technology to address current and future anticipated nutrient limits. Other key elements include new screening and grit removal facilities, primary clarification, biological nutrient removal, offline equalization tanks for peak flow management, aerobic digesters, a new solids dewatering facility with high efficiency screw press technology, ultraviolet disinfection, and post-aeration of effluent.

The $350-million progressive design-build facility expansion is the largest single capital project in the County’s history. Wade Trim is providing construction management support and subject matter expertise throughout the 46-month effort as part of the project’s third-party construction management team. The Big Creek WRF expansion is anticipated to be complete in 2024. Once operational, the County will operate one of the largest membrane bioreactor treatment systems in the United States.
