Project Name: RM Clayton WRC – Headworks

Constructed in 1935, the RM 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. 
 
RM Clayton WRC receives influent flows from the combined stormwater and sanitary sewer collection systems.  Sanitary sewer flows are also stored and conveyed to the RM Clayton WRC through a deep rock tunnel system, which is pumped to the WRC influent collection box by the Nancy Creek pumping station located at the RM Clayton WRC. These various sources of influent flow result in wide fluctuations in the WRC’s influent flow rates and fluctuations in the solids loadings at the headworks facility.  
 
Constructed in 2000, the headworks facility provides raw wastewater screening and grit removal, critical functions to the wastewater treatment process. Inadequate performance of the headworks facility can promote adverse impacts to downstream treatment processes. As a result of age and performance, the existing mechanical screens, screening handling equipment and grit removal units of the headworks facility in need of repair and/or replacement. 
 
The scope of this project includes: 

•   Replacing the existing coarse screening and grit removal systems 
•   Installing influent monitoring equipment for accurate monitoring of flows 

 
Justification: 

•   Enhances system operational efficiency and reliability 
•   Facilitates compliance with National Pollution Discharge Elimination System (NPDES) permit
