Water Supply Program




The City of Atlanta’s raw water system infrastructure forms the foundation and starting point for delivering clean and reliable drinking water as well as fire protection service for more than 1 million system users. In the 1890’s, when Atlanta faced major public health issues with water quality and water availability, the investment in raw water conveyance and storage was the first step in securing a sound future for the City. Since then, that investment has been integral to the success of Atlanta’s economy and the health of its citizens. Now, over 120 years later, Mayor Kasim Reed recognizes the critical need for reliable delivery of clean and safe drinking water to the City and neighboring jurisdictions that rely on the City for this vital resource.
The original raw water pipelines are still in service. Cast iron mains of diameters 30”, 36”, and 48” were installed in 1893, 1908, and 1924 respectively. Although these were renewed with a cement liner in the 1950s, they have far exceeded their design life. A fourth line, 72” steel main, was built in 1975 and metallurgical weaknesses restrict its operation to warm weather months. Our water supply must be protected, conserved, shared, and sustained for future generations. The vision of the next 100 years of drinking water for the Atlanta area includes renewing the foundation of our water supply system and ensuring secure and reliable delivery.
The Chattahoochee River is the source of raw water for the entire Metro Atlanta. The path of the new conveyance system will follow closely the path of the current cast iron lines. The new five-mile conveyance will end at a quarry site that will be transformed into a new water storage facility. It will be designed to meet the current withdrawal permit limits and store any excess water not used for daily drinking water. Once filled, this facility will hold 2.4 billion gallons of water to provide the City a 30-day backup water supply.
The program design will address the objectives of achieving 100 years of asset lifecycle and flexibility in system operations. The estimated cost of design and construction for conveyance and water storage is approximately $280M.

On November 20, 2014 the City of Atlanta held an industry forum to introduce the new Water Supply Program.  The Water Supply Program reflects Mayor Kasim Reed’s emphasis on securing Atlanta’s water supply for the next 100 years. The Department of Watershed Management delivered this program, which included the following main components:

·Conversion of the Bellwood Quarry into a 2.4 billion gallon water storage facility.
·Construction of a 10-foot diameter tunnel that is over 5 miles long to connect the new water storage facility, Hemphill WTP, Chattahoochee WTP and the Chattahoochee River intake.
·Installation of pump stations and associated vertical shafts, flow control devices, and instrumentation and control systems.
