The Western Virginia Water Authority was formed on July 1, 2004 when the water and wastewater operations of the City of Roanoke and Roanoke County consolidated. Five years later, on November 24, 2009, Franklin County officially joined the Western Virginia Water Authority and Botetourt County joined on July 1, 2015. The Town of Boones Mill's utility system was acquired in December 2021, and on July 1, 2022, the Authority acquired the Town of Vinton's waster and wastewater systems. The Authority now provides water service to over 69,000 customer accounts and wastewater service for more than 60,000 accounts in the City of Roanoke, the Counties of Roanoke, Franklin and Botetourt and the Towns of Boones Mill and Vinton. The Authority also contracts to operate the water and wastewater system for the Town of Fincastle.
