How is the surface water from Lake Granbury treated to come to our faucets?
Lake Granbury SWATS is a regional desalinization-type water treatment plant providing wholesale treated water to customers in Hood and Johnson County areas. These customers include Johnson County Special Utility District, Acton Municipal Utility District, the City of Granbury and the City of Keene. The SWATS plant diverts and treats raw water from Lake Granbury. In addition to conventional water treatment, the SWATS plant utilizes advanced membrane technology including a process called Ultrafiltration/Reverse Osmosis (UF/RO) which removes pathogens and chlorides (salts) and process the final product to an acceptable drinking water level.
