Utoy Creek WRC

The Utoy Creek WRC is located at 805 Selig Drive off Fulton Industrial Boulevard in unincorporated Fulton County. The facility provides wastewater treatment for the sewer service area that encompasses portions of southwest Atlanta, northwest Atlanta, East Point and a portion of Fulton County. The facility is designed to treat 44 million gallons per day (mgd) of wastewater for discharge to the Chattahoochee River under a National Pollutant Discharge Elimination System (NPDES) Permit.

The Utoy Creek WRC was originally constructed in 1936 and was expanded in 2000 to a maximum monthly flow of 44 mgd. In the 1980s, the facility was expanded with the addition of a new secondary treatment facility. The most recent upgrades include new screening and grit removal facilities, upgrade of the primary clarifiers, conversion and expansion of the existing aeration tanks to optimize biological carbon oxidation, nitrification and phosphorus removal, secondary clarification, effluent filtration, ultraviolet disinfection and post-aeration. Other related improvements include new sludge thickening, dewatering and incineration facilities and odor control systems.

The treatment process removes biological and chemical impurities from the wastewater making it suitable for discharge to the Chattahoochee River in three phases: primary treatment, secondary treatment, and tertiary treatment. The primary treatment process begins with the removal of floatable and settleable solids. Removed solids are hauled to a landfill for disposal. Next, biological treatment during the secondary treatment phase reduces the concentration of organic and chemical pollutants. Finally, tertiary treatment removes the remaining suspended solids, disinfects the treated water using ultraviolet radiation, and increases dissolved oxygen concentrations before discharging to the Chattahoochee River. The biological solids that are removed during the wastewater treatment process are reduced in the digestion process before being dewatered and incinerated or hauled to a landfill.
