During an unparalleled time of growth in Atlanta, Georgia, Gwinnett County, the largest county in metropolitan Atlanta, selects subterranean tunnel storage for wastewater in lieu of surface facilities. Faced with the necessity to convey wastewater upgradient through intensely developed area, Gwinnett County has implemented a 2000-ft. long, 6.5 ft. diameter tunnel in a 30,000-psi gneiss formation to store peak flows until pumping systems catch up. Traditionally drill and shoot tunnel methods of excavation would have been used; however, sensitive apartment buildings and a major interstate crossing made a tunnel boring machine (TBM) the preferred option. The tunnel lining (cast-in-place concrete or reinforced concrete pipe) was bid as alternates for fiberglass reinforced polyester pipe (FRP). A Robbins DS TBM with an 8-ft. bore was selected along with a 6.5-ft. diameter, 1.8-inch thick FRP lining. Tunnel storage saved over 1 MM versus other storage and conveyance alternatives. Environmental and community impacts were also greatly reduced compared to other alternatives.
