Water Supply

photo of girl drinkingAlthough the TVA region usually receives abundant rainfall, averaging 51 inches per year, several extended dry periods during the past 25 years have heightened public awareness of water as a limited resource that must be protected and managed.

The Tennessee River watershed will add about 1.2 million more residents to the existing 4.7 million by 2030, according to recent projections by TVA and the U.S. Geological Survey. Additionally, growth in urban areas around the region, some of which are already facing water-supply challenges, will increase pressure on the TVA region’s water resources.

TVA is working with other federal agencies, state and local governments, and communities across the TVA region to meet these challenges. The goal is to ensure adequate, sustainable supplies of water for the region’s continued growth.

Managing the Tennessee River for water supply

TVA’s integrated management of the Tennessee River provides water for a wide range of public benefits. These include water for drinking, industrial use and agriculture; for generating hydropower and cooling nuclear and fossil power plant components; and for navigation, recreation and sustaining plant and animal life.

In some cases, these uses of water compete, especially under drought conditions. TVA is committed to developing regional partnerships to deal with these conflicts and help respond to the population and environmental pressures of the coming decades. Learn more about TVA’s water supply activities.

Water conservation

Conserving water not only reduces the demand we put on our water supply, it’s also good for the environment. Communities in the TVA region that use less water produce less wastewater. When there’s less runoff from lawns, sewage treatment, soapy water from car-washing, and other sources flowing into our streams and rivers, water quality improves. Users downstream have cleaner water for drinking, swimming, fishing and use by industry.

Water conservation also contributes to cleaner air by reducing the amount of energy needed to heat, transport and process water. These water and energy savings show up on our utility bills. Find out what you can do to conserve water.
