Water Use in Georgia, 2010
Science Center Objects
Total water use, for 2010,was 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2,230 Mgal/d of water was returned to surface-water bodies in Georgia and represents about 48% of the water withdrawn in 2010.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.

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:
- water withdrawal;
- offstream treatment, distribution and delivery (including conveyance or system losses), and consumptive use;
- land application of treated wastewater;
- surface-water returns; and
- 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withdrawals (1,190 Mgal/d).Thermoelectric power facilities and public supply systems withdrew nearly 68% of all water withdrawn in Georgia for 2010. Surface-water withdrawals used in the process of thermoelectric-power generation was the largest volume of water withdrawn (2,040 Mgal/d) followed by public supply systems (1,120 Mgal/d.) Crop irrigation withdrew the largest amount of groundwater (578 Mgal/d).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.

Download the spreadsheet of water use in Georgia, by county and category of use, for 2010
This diagram uses a "cylinder and pipe" layout to show the source (surface water or groundwater) of the Georgia's freshwater and for what purposes the water was used in 2010. The data are broken out for each category of use by surface water and groundwater as the source. The top row of cylinders represents where America's freshwater came from (source) in 2010, either from surface water (blue) or from groundwater (brown). The pipes leading out of the surface-water and groundwater cylinders on the top row and flowing into the bottom rows of cylinders (green) show the categories of water use where the water was sent after being withdrawn from a river, lake, reservoir, or well. Each green cylinder represents a category of water use.

Water Use by County, 2010
Total water use for Georgia, 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.

Water Withdrawal Trends, 1980-2010 in Georgia\
Since 1980, the Georgia Water-Use Program (GWUP) has compiled and published statewide water-use estimates by category at 5-year intervals. National water-use compilations began in 1950. However, during the period 1950-2010, water-use estimates were not always comparable. Category definition and estimation techniques have been the most consistent since 1980 because of efforts of the National Water-Use Information Program (NWUIP). Withdrawals in Georgia were highest in 1980 (6,730 million gallons per day (Mgal/d)). By 1990, water use had decreased by 20 percent to 5,350 Mgal/d, but increased to 6,490 Mgal/d in 2000. By 2005, water use had decreased to an estimated 5,470 Mgal/d, and declined further to 4,670 Mgal/d in 2010-a 30-percent decrease since 1980. This decline was evident across all water-use categories, but was greatest for surface-water withdrawals by thermoelectric-power facilities.

Water Use in South Carolina, 2010
The future health and welfare of the Nation's population is dependent upon a continuing supply of uncontaminated fresh water. Increasing withdrawals and increasing demands for instream flows are limiting the water available for future use. The USGS compiles water-use data from numerous sources for all parts of the country, and since 1950 has published a series of Circulars on the estimated use...

Water use in the Apalachicola-Chattahoochee-Flint River Basin, Alabama, Florida, and Georgia, 2010, and water-use trends, 1985-2010
The Apalachicola-Chattahoochee-Flint (ACF) River Basin encompasses about 20,230 square miles in parts of Alabama, Florida, and Georgia. Increasing population growth and agricultural production from the 1970s to 2010 has prompted increases in water-resources development and substantially increased water demand in the basin. Since the 1980s, Alabama...

Summary of estimated water use in the United States in 2005
About 410,000 million gallons per day (Mgal/d) of water was withdrawn for use in the United States during 2005. About 80 percent of the total (328,000 Mgal/d) withdrawal was from surface water, and about 82 percent of the surface water withdrawn was freshwater. The remaining 20 percent (82,600 Mgal/d) was withdrawn from groundwater, of which about...
