Your Water Source: The Chattahoochee River

The source for DeKalb County's drinking water is the Chattahoochee River. DeKalb County has a Raw Water Pumping Station, in north Fulton County above the City of Atlanta.Test

The Chattahoochee River begins as a small stream just north of the northeast Georgia community of Helen. As the Chattahoochee flows across the State of Georgia, the river forms the major drainage basin for the North Georgia region. Lake Sidney Lanier, upstream of DeKalb County's intake, releases water for the daily water supply for downstream municipalities and to support the aquatic environment of the river.

The U.S. Army Corps of Engineers (USACE) contracts with the Atlanta Regional Commission guaranteeing a maximum daily flow of 377 million gallons. The USACE must also supply a minimum flow of 750 cubic feet per minute in the river at Peachtree Creek. The Georgia Department of Natural Resources, Environmental Protection Department permits DeKalb County to withdraw a maximum of 140 million gallons per day from the Chattahoochee River.
