Atlanta is one of the fastest-growing cities in the U.S., with a population that is expected to surge by 50% over the next 30-years. This growing population needs a secure water supply.

Currently Atlanta takes its water from the Chattahoochee River and has just three days of reserve. Therefore, the City of Atlanta’s Department of Watershed Management is currently constructing a $347 million Water Supply Program, including the conversion of an over-a-century-old rock quarry into a 2.4 billion-gallon raw water storage facility, which will increase the minimum water supply for the city to more than 30 days.

The project includes 5-miles (8km) of 300ft to 450ft (90m to 140m) deep, 12ft (3.65m) diameter, tunnel bore, and eleven shafts of various types and sizes. The quarry site is also being converted into publicly accessible parkland connecting Atlanta’s BeltLine park and trail system.

The tunnel is being mined by TBM from a portal at the base of the quarry and will connect the quarry to two water treatment plants and four pump stations. The project is being delivered using the Construction Manager at Risk (CMAR) model, an innovative contracting method that is fairly new to the tunneling industry.

This morning tour, hosted by Stantec and Atkinson/Technique JV, will take in key points of interest at the quarry construction site and various shafts related to the site facilities.
