The original Canyon Lake Water Supply Corporation became an operating entity in 1994 as a member-owned non-profit water utility, consolidating 46 separate ground water systems. The residents of the 46 independent systems were consuming groundwater from Trinity Aquifer wells which yielded an insufficient quantity of water to meet the summer peak demand. The Supply Corporation founders recognized that groundwater supplies alone were inadequate to support the water demands of a growing community and that centralized surface water treatment plants would make it possible to distribute surface water from Canyon Lake to the residents in Comal County. Since the original acquisition of the Supply Corporation in 2006, SJWTX has grown from approximately 6,000 connections to over 16,650 connections by both acquisition of neighboring systems, growth from new development and organic growth in existing subdivisions.
SJWTX, Inc. (SJWTX), incorporated in the State of Texas in 2005, is doing business as Canyon Lake Water Service Company (CLWSC) after acquiring the Canyon Lake Water Supply Corporation. Providing water and wastewater utility services in Comal and Blanco Counties, the utility has grown from approximately 7,000 service connections in 2006 to more than 23,900 in 2021, and now serves a large 250 square mile service area.
