Water Supply Basics
Water is essential to our livelihood in both business and in our homes. In the 16-county Metropolitan North Georgia Water Planning District, approximately 652 million gallons a day (MGD) are used each day. The majority of this water is from surface water sources, the most important being the Chattahoochee River/ Lake Lanier and the Etowah River/Lake Allatoona which provide 84% of the regional total water supply.
Unlike other metropolitan areas, Atlanta is not located on a major body of water. Though the Atlanta Region averages just over 50 inches of rainfall each year, our rivers and streams are relatively small. Consider the following:
- The District area relies on surface water for 98% of its needs. Bedrock, like Stone Mountain granite, below the region limits groundwater sources.
- Because the Atlanta region is located at the headwaters of its rivers and streams, flow is limited
Where does the water come from?
