Clear Creek CSO

The Clear Creek CSO Treatment Facility is one of the West Area CSO facilities and is located at 1320 Monroe Drive. Constructed in 1996, the Clear Creek CSO Treatment Facility is unique in that it was designed to be compatible with the architecture of surrounding residential and commercial establishments. Comprised of approximately 3,086 acres and having a maximum overflow capacity of approximately 5,060 million gallons per day (mgd), the Clear Creek CSO Facility serves the largest combined sewershed of the City’s seven CSO facilities, and includes the Downtown Business District and Midtown Atlanta. Dry weather flow (less than 40 mgd is routed to the Peachtree interceptor, which then takes the flow to the R.M. Clayton WRC for treatment. Wet weather flow is routed to the Clear Creek CSO facility for treatment before being discharged to an open channel that leads to Clear Creek. Existing treatment consists of coarse screening, fine screening, and disinfection by sodium hypochlorite. The sodium hypochlorite injection occurs upstream of the Clear Creek CSO Facility to provide for proper disinfection and for minimized chlorine residual prior to discharge to Clear Creek. The injection point also assures that all CSO, both screened and unscreened (bypassed), is disinfected.
