COMMUNITY FACILITIES AND SERVICES Water Supply and Treatment The City of Atlanta’s water supply and treatment system is owned and operated by the City of Atlanta Department of Watershed Management (DWM). It serves a popula on of more than 1.2 million people, including approximately 540,291 (2009 US Census popula on es mate) residents and a work force of 378, 109 (according to the GA Department of Labor) . In 2009, the City’s average daily water produc on was 90 million gallons per day. Service Area The geographic area served by the City of Atlanta’s water treatment and distribu on system covers an area greater than 650 square miles. It includes the City of Atlanta, and all local governments and jurisdic ons in Fulton County The Cha ahoochee River is the source of water for the City of Atlanta. south of the Cha ahoochee River, with the excep on of East Point and College Park. Harts eld-Jackson Airport and Fort McPherson are also included in the City’s service area. Within this area the City of Atlanta provides water on a wholesale basis to the ci es of Fairburn, Hapeville and Union City. Coweta, Clayton and Faye e coun es are also wholesale customers. The boundaries for the City of Atlanta’s retail service area are the boundaries for the City of Atlanta and unincorporated Fulton County prior to Fairburn and Union City’s November 2006 annexa ons. As such, all of Sandy Springs and the City of Cha ahoochee Hill Country, along with a por on of Fairburn and Union City are within the retail area served by the City of Atlanta. The City also provides water to Fulton County north of the Cha ahoochee River. The City’s service area is shown in Map 5-1. Water Supply Facili es The City of Atlanta’s water supply and treatment system consists of mul ple Atlanta Water Works on 14th Street facili es and an extensive network of water mains. Key to this system are two intake structures, two raw water pumping sta ons, three reservoirs, three treatment plants, een pump sta ons, 12 storage tanks, ve major administra ve facili es and approximately 2,700 miles of water mains and pipes. The Cha ahoochee River Intake operates pursuant to a withdrawal permit of 180 mgd from the Georgia Environmental Protec on Division (EPD) and is the source of water for the Cha ahoochee and Hemphill Water Treatment Plants (WTPs). Water from the intake ows to the Cha ahoochee Raw Water Pumping Sta on. Water is then pumped to the Hemphill WTP reservoirs or the Cha ahoochee WTP. The Cha ahoochee WTP has a maximum permi ed treatment capacity of 64.9 million gallons per day (mgd). The two raw water reservoirs located at the Hemphill Water Treatment Plant have a total capacity of approximately 550 million gallons. Water ows from the raw water reservoirs to the Hemphill Water Treatment Plant which has a permi ed maximum treatment capacity of 136.5 mgd. Atlanta Water Works on Northside Drive. The Atlanta-Fulton County Water Treatment Plant (AFCWTP), a joint venture plant owned by the City of Atlanta and Fulton County, is managed by the 183 CCommunityommunity AssessmentAssessment - 5.5.

The City of Atlanta and Fulton County jointly own the land and the facility on a y- y basis. Each en ty is en tled to 50% of the total supply of water treated by the plant at any me or y percent of the capacity, whichever is greater. The AFCWTP intake operates pursuant to a withdrawal permit of 90 mgd from the Environmental Protec on Division (EPD). This water withdrawal permit is an cipated to be increased to 135 mgd and is the source o water for the Atlanta-Fulton County Water Treatment Plant. The raw water is pumped from the Cha ahoochee River to the raw water reservoir which has capacity of approximately 1 billion gallons. From the reservoir the water ows to the AFCWTP, which has a permi ed capacity 90 mgd. Ul mately, this plant is an cipated to be expanded to 155 mgd. Water Distribu on System Hemphill WTP Reservoirs. The City of Atlanta’s water distribu on system consists of een storage tanks, twelve pump sta ons and approximately 2,700 miles of water mains. The City of Atlanta owns and operates the distribu on system within the City of Atlanta, including the por on of the City that lies within DeKalb County, and within the por on of unincorporated Fulton County which is located south of the Cha ahoochee River. The City’s distribu on system includes the pipelines required to service the City’s retail customers up to the edge of the right-of-way where ownership of the pipeline transfers to others. The City uses its distribu on system to deliver water to its wholesale water customers. The water lines in the City’s system range in age from one year to over seventy- ve years and have diameter ranging from two to seventy-two inches. Nearly all of the pipes are constructed of cast iron or duc le iron. The older pipes are cast iron, with the installa on of duc le iron pipe star ng in the 1960’s. Hemphill Water Treatment Plant. The distribu on system storage tanks and pump sta ons serve to dampen instantaneous water demand and pressure uctua ons in the service area. The pump sta ons allow water to be pumped up hill and ensure that there is adequate pressure throughout the water system. A majority of the pump sta ons operate on standby status to be u lized during peak demand or in the event service from the Atlanta-Fulton County WTP is interrupted. The storage tanks provide backup water during peak demand or when there is a loss of pressure in the system. Elevated storage tanks are used to maintain pressure in the distribu on system for general water delivery and re ow protec on. Overall, the distribu on system has approximately forty- two (42) million gallons of storage (excluding storage at the water treatment facili es). In addi on to its treatment plants and pump sta ons, the Department of Watershed Management u lizes mul ple permanent and temporary facili es to support its water, wastewater and soon-to-be stormwater func ons. The Department faces considerable space shortages and maintenance facili es Cha ahoochee Water Treatment Plant. for both its water and wastewater opera ons are needed.

City of Atlanta Growth and Development and Water Supply Level of Service and Adequacy of Facili es to Meet Future Needs The level of service provided by the City’s drinking water system is good. The water treatment plants have adequate capacity, water is rou nely distributed throughout the distribu on system to the City’s customers, and the City’s drinking water meets all water quality standards. The City produced an average of approximately 90 million gallons per day (mgd) of drinking water. By 2030, the City an cipates that up to 149 mgd will be needed on an average daily basis with peak demand reaching upwards of 239 mgd. This gure is based upon the assump on that a 10 percent reduc on Atlanta Fulton County Water Treatment in per capita water usage based on water conserva on will be achieved by Plant in the City of Johns Creek. 2030. To meet these water supply needs the City has proposed the conversion of the Bellwood Quarry into a raw water reservoir. This reservoir is an cipated to provide over two billion gallons of raw water storage. The development of such a reservoir in conjunc on with maintaining the ability to withdraw 180 mgd at the Peachtree intake, increasing the AFCWTP permit to allow a withdrawal of 135 mgd, and supplemen ng the City of Atlanta’s water supply with a por on of the 53 mgd of wholesale water to be made available to Fulton County from Cobb County (as outlined in the 2003 Metropolitan North Georgia Water Planning District Water Supply and Water Conserva on Management Plan), is an cipated to meet the City’s water supply needs through 2030 and beyond. Although the City of Atlanta’s water treatment supply and distribu on facili es currently meet system demands, signi cant capital improvements are needed to ensure the ongoing delivery of water throughout the service Bellwood Quarry Reservoir. area and to develop and maintain the system to meet future demands. These needs include: o The ongoing replacement of infrastructure that has reached its useful service life; o The upgrading and/or replacement of exis ng water mains, pump sta ons, and tanks to provide addi onal water to growing areas and to extend water service into areas where service has previously not been provided; o The ongoing installa on and replacement of water meters to ensure that all customers pay a fair price for the water they receive, and that fees for water are collected; o The upgrading and replacement of equipment and systems to maintain and improve system operability and e ciency and; Operator at the Hemphill Water Treatment Plant.
