Reality Modeling for Remote Design of Advanced Wastewater Treatment Plant Expansion

By Sandra DiMatteo

Gwinnett County, Georgia, northeast of Atlanta, has a population of 950,000. The Gwinnett County Department of Water Resources (GCDWR) provides wastewater treatment services to these residents via the F. Wayne Hill Water Resources Center. Originally constructed in 2000, it utilizes advanced ozone, granular activated carbon, and membrane treatment processes to return high-quality effluent to the Chattahoochee River and Lake Lanier while going beyond regular water quality requirements. Since it began operations, the facility has received a number of awards from water associations, including the Platinum 18 Peak Performance Award from the National Association of Clean Water Agencies, and has never received a water quality violation.
