Regional Reservoir
Canyon Lake
SAWS is about 98% groundwater based, only 2% of its total water demand came from a surface water reservoir in 2024. SAWS currently has one surface water project, known as The Western Canyon project, which was established in April of 2006, delivering treated water from Canyon Lake to SAWS customers. The project is a successful alliance between the GBRA (Guadalupe-Blanco River Authority) and water purveyors in Comal, Kendall, and Bexar counties. SAWS has an agreement to receive a minimum of 4,000 AFY*. In 2024, SAWS purchased about 5,900 AF from this supply to meet customer demand.
