Chattahoochee WTP

The Chattahoochee Water Treatment Plant (WTP), located at 2532 Bolton Road, is a manually operated treatment plant and is staffed 24 hours a day, 7 days per week and has a maximum capacity of 64.9 mgd. The Chattahoochee WTP supplies water to the Northside and Adamsville Repump Stations, which transfer water to the Buckhead and South Fulton areas of the system respectively. The Chattahoochee WTP receives raw water directly from the Chattahoochee Raw Water Pumping Station. No raw water storage is currently available at the Chattahoochee WTP. Constructed in 1961-1962, the Chattahoochee WTP originally contained six (6) filters. The plant was upgraded in 1968-1970 with the addition of seven (7) new filters and currently operates using thirteen (13) filters. The current treatment process at the plant consists of flocculation, sedimentation, filtration, disinfection and storage. Raw water from the Chattahoochee Raw Water Pumping Station flows into the plant where chemicals are added to promote flocculation. The water/chemical mixture is allowed to form floc and the solids to settle in the sedimentation basins. The Chattahoochee Settled Solids Facility is responsible for processing all solid wastes from the Chattahoochee WTP. The dewatered solids are transported to landfills where they are used as cover material. (An alternative Belt-Press unit is currently being used at this facility in a pilot study for conversion to the new technology.) When the heavier solids have been removed, water flows through the filters to remove any solids that remain. Finally, the water is disinfected with chlorine to kill any remaining bacteria that might be in the water. Finished water is stored in the clear wells at the facility until it is sent into the distribution system. The Chattahoochee WTP has four finished water pumps that send water to the distribution system.
