Water Quality Fun Fact
Did you know...
We test for approximately 160 different substances in in a given year to ensure the quality of your drinking water.
To find more detailed results about the highest priority substances, check Consumer Confidence Report for your respective system!
Systems in the Canyon Lake area received water from Canyon Lake, groundwater from the Trinity Aquifer, and sometimes both depending on what system you live in. If you live in a system that receives water from both, know that these sources are often blended together in the distribution system. You may receive different sources from day to day as customer usage changes.
Canyon Lake Area Water
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.
SJWTX 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 require filtration; it only requires disinfection.
Deer Creek Water
The Deer Creek system uses water from Lake Austin. Lake Austin is operated by the Lower Colorado River Authority under the rules and regulations of the U.S. Army Corps of Engineers. The water from Lake Austin is purchased from the Lower Colorado River Authority, and is treated and distributed to the Deer Creek system by the West Travis County Public Utility Agency. Once the water reaches the Deer Creek system it is managed by SJWTX, Inc., which works to ensure that service and quality are maintained within the system.The water is treated and delivered to Deer Creek customers by the West Travis County Public Utility Agency.
Water Quality Reports
The Consumer Confidence Report (CCR) is a document that provides consumers with information about the quality of drinking water in an easy to read format. The CCR summarizes information that SJWTX collects to comply with Federal and State (TCEQ) regulations.
