About SJWTX, DBA Canyon Lake Water Service Company

Canyon Lake Water Service Company is a state-regulated investor-owned utility providing water service to approximately 40,000 people through more than 17,200 connections in Comal, Blanco, Hays, and Travis Counties. On May 31, 2006, the utility became part of the SJW Corp. via the purchase of Canyon Lake Water Supply Corporation by SJWTX, Inc. SJWTX is a subsidiary of SJW Group, a publicly-traded company listed on the New York Stock Exchange under the symbol SJW. Although the name has changed, CLWSC’s rich history and commitment to outstanding customer service remain the same.


The original Canyon Lake Water Supply Corporation became an operating entity in 1994 as a member-owned non-profit water utility, consolidating 46 separate groundwater 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, CLWSC has grown from approximately 6,000 connections to over 13,400 connections by both acquisitions of neighboring systems, growth from new development and organic growth in existing subdivisions.

The Service Area 

Canyon Lake is located on the Guadalupe River in the Texas Hill Country. The CLWSC service area surrounds Canyon Lake and includes approximately 250 square miles within Comal County and southern Blanco County. CLWSC infrastructure includes over 590 miles of pipes, three surface water treatment plants and over forty active wells located throughout the system. The Canyon Lake community continues to evolve with new developments and a wide range of demographics. The growth has fueled a building boom in housing, new schools, public parks, and a variety of businesses and service industries. CLWSC recognized the growing interest in centralized wastewater collection and treatment. We currently operate three wastewater treatment facilities and a fourth is under construction, all in Comal County.
