Project Name: Intrenchment Creek WRC Decommissioning/South River WRC Primary Clarifiers Replacement

Includes project:

Originally constructed in 1910 and upgraded in 1936, the Intrenchment Creek Water Reclamation Center (WRC) provides wastewater treatment for the northern half of the South River sewer service area, which encompasses portions of Atlanta and a small portion of DeKalb County. Because Intrenchment Creek WRC is no longer capable of meeting modern effluent limits, treated wastewater will be conveyed to the South River WRC for further treatment before being discharged to the Chattahoochee River under a National Pollutant Discharge Elimination System (NPDES) permit. 
 
The scope of the South River WRC project includes: 

•   Providing primary clarifiers, head house and odor control ductwork  
•   Replacing chemical feed building and prefabricated warehouse building for new clarifiers  
•   Providing new poly aluminum chloride (PAC) chemical feed facility 
•   Rehabilitating the force main from Intrenchment Creek WRC to South River WRC headworks

  
 
The scope of the Intrenchment Creek WRC includes:  

•   Providing new grit traps for the Intrenchment Creek Sewer and the Sugar Creek Sewer 
•   Providing new effluent and influent pump stations and influent primary storage tank 
•   Providing odor control facility for bar screens and new primary storage tank   
•   Repairing Intrenchment Creek WRC force main 
•   Decommissioning primary and secondary treatment facilities 

 
Justification: 

•   Allows wastewater to be sent directly to South River WRC for secondary treatment 
•   Leverages existing wastewater treatment assets while maintaining permit compliance 
•   Enhances system operational efficiency and reliability 
•   Reduces corrective and emergency maintenance
