Constructed as part of the $4-billion Clean Water Atlanta Program, the $111-million South River Tunnel and Pumping Station project, currently under construction for the City of Atlanta, will mitigate sanitary sewer overflows in the city�s South River Basin.

GSC Atlanta, a subsidiary of Kiewit Southern Co. in Peachtree City, Ga., is targeting a July 1, 2011, completion date.
The company is building a 9,000-ft-long, 14-ft-diameter tunnel that will collect flows from existing sanitary sewers and transport them to a newly constructed, 45-million-gallon-per-day pumping station at the South River Reclamation Center.
A joint venture between Jordan, Jones & Goulding of Norcross, Ga., and Atlanta Services Group of Atlanta designed the project.
