RM Clayton Emergency Dewatering and Hauling

complete

Constructed in 1965, the R.M. Clayton Water Reclamation Center (WRC), located in northwest Atlanta along the Chattahoochee River, provides wastewater treatment for a service area that encompasses north of I-20, a small portion of north Fulton County adjacent to Sandy Springs, and most of north DeKalb County. The facility is designed to treat an average daily maximum monthly flow of 122 million gallons per day (MGD) of wastewater for discharge to the Chattahoochee River under a National Pollutant Discharge Elimination System (NPDES) Permit. The treatment process removes biological and chemical impurities from the wastewater in three phases: primary treatment, secondary treatment, and tertiary treatment. The primary treatment process begins with the removal of floatable and settleable solids. 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. Biological solids removed during the wastewater treatment process are reduced in the digestion process before being dewatered and incinerated or hauled to a landfill. The biological solids handling systems in need of additional capacity in order to handle excessive grit and debris loading. Other WRCs may also be included.
