Water Use in Georgia, 2010

Estimates of water withdrawals, surface-water returns (treated and untreated water), and water use for each county in Georgia for nine water-use categories were compiled for 2010. The term "water use" is broadly applied to describe the movement of water from its natural source, through its interaction with human activities, and its subsequent return to the natural environment. This water-use model consists of various components such as:

  1. water withdrawal;
  2. offstream treatment, distribution and delivery (including conveyance or system losses), and consumptive use;
  3. land application of treated wastewater;
  4. surface-water returns; and
  5. instream use (such as hydroelectric-power generation).

For 2010, these components were further subdivided into the categories of public supply, domestic, commercial, industrial, mining, irrigation, aquaculture, livestock and thermoelectric power.

In 2010, total withdrawals for groundwater and surface-water sources were estimated at 4,670 million gallons per day (Mgal/d) with surface-water withdrawals (3,480 Mgal/d) nearly three times greater than groundwater withdrawals (1,190 Mgal/d).Thermoelectric power facilities and public supply systems withdrew nearly 68% of all water withdrawn in Georgia for 2010. Surface-water withdrawals used in the process of thermoelectric-power generation was the largest volume of water withdrawn (2,040 Mgal/d) followed by public supply systems (1,120 Mgal/d.) Crop irrigation withdrew the largest amount of groundwater (578 Mgal/d).

Total water use, for 2010, is estimated at 4,680 Mgal/d which included 1,130 Mgal/d of water delivered by public suppliers to domestic, commercial and public use, and industrial customer and publics supply losses. About 6.7 Mgal/d of water was delivered from public suppliers in Alabama and Tennessee to customers in Georgia. Furthermore, 2,230 Mgal/d of water was returned to surface-water bodies in Georgia and represents about 48% of the water withdrawn in 2010. About 32% (711 Mgal/d) of all surface-water returns was treated wastewater from public treatment facilities.
