Custer Avenue Combined Sewer Outflow - Construction of a Storage & Dechlorination Facility in Atlanta, Georgia, USAThe City of Atlanta has been extensively upgrading its sewer and water supply systems for the past few years. Within the framework of these construction projects, DSI Ground Support, Salt Lake City, is involved in supplying three of these projects: Nancy Creek, Atlanta CSO and Custer Avenue CSO. Construction for the combined sewer overflow project at Custer Avenue began in August 2005 and was carried out by Gunther Nash (a subsidiary of the Alberici Group) under a design build contract. Its completion is expected for early 2007. The following underground excavation components are part of the work:
- Access shaft - a 40 m deep shaft with an inside diameter of about 5 m to be used for tunnel construction and access to the storage facility during its lifetime,
- Storage facility - a 183 m long arched chamber with a nominal span of 18 m and a height of 17 m,
- Connecting tunnels - short 4.5 m span horseshoe shaped tunnels,
- Ventilation shaft - required for providing fresh air to the storage facility.
