Texas Water utilizes many different resources to supply water to our systems. These sources include purchased water, groundwater from the Trinity Aquifer, and surface water from Canyon Lake. Some systems receive water from a blend of these sources. To determine which water system provides water to your tap, type your address into the sidebar to the right to “Find Your Water System.”
Systems in the Canyon Lake Area receive surface water from the Canyon Lake Reservoir. In addition to providing drinking water, the lake is operated by the U.S. Army Corps of Engineers to mitigate flood damage to the Guadalupe River Basin and offers recreation opportunities in Texas.
Texas Water utilizes almost 40 active wells to supply groundwater to customers. Groundwater is helpful from a water quality perspective because it does not contain the amount of organic material and contaminants seen in surface water, so it does not typically require filtration; it only requires disinfection.
DEER CREEK WATER
The Deer Creek system uses water from Lake Austin. This water is purchased from the Lower Colorado River Authority, which operates under the U.S. Army Corps of Engineers. The water is treated and delivered to Deer Creek customers by the West Travis County Public Utility Agency. Once the water reaches the Deer Creek system, it is managed by The Texas Water Company, which ensures that service and quality are maintained within the system.
