Finding and Fixing Hidden Leaks is Critical

Leak Detection

After record-breaking cold, many central Texans are chasing leaks and working to restore  water service. Water utility customers can use their meters to check their plumbing integrity, but well owners will have a harder time verifying that all leaks have been found. Groundwater levels in our aquifers are low, and the NOAA Climate Prediction Center forecasts that drought will persist in our area at least through the spring if not longer, so finding leaks will help secure our water supplies and protect Hill Country springs, creeks, and rivers. Here’s how:

Water utility customers, pick a two-hour timeframe your whole household can avoid using water. Read your meter (take a photo). After two hours of no water use, read it again and compare it to your previous reading. With no leak, the number should be the same. With a leak or leaks, the meter will show your unintentional water use. If these leaks continue, they will needlessly increase your water bill and deplete water storage in our aquifers.

Well owners, without a meter hidden leaks are more difficult to identify. While not using water, go out to your well house to monitor the pressure tank and listen for the well pump to cycle. If there is no leak, pressure should remain steady and the pump should not have to cycle. A leak would drain water from the pressure tank, and it would lose pressure over time. If you would like to have a professional examine your system, a list of licensed pump and well servicers is available through the Texas Department of Licensing and Regulation. If a leak or leaks continue, costly well and septic system components could wear out faster than with normal use and the increased water use could pointlessly deplete groundwater supplies.
The Texas Hill Country is drought-prone and groundwater-dependent. Fixing hidden leaks now has benefits at multiple scales—from individual homes to neighborhoods and the region.

    • EPA Fix-A-Leak page: The average household’s leaks can account for nearly 10,000 gallons of water wasted every year and ten percent of homes have leaks that waste 90 gallons or more per day.  This page has important guidance for finding leaks and fixing them.
    • Using your meter to check for leaks (video):  An expert with the Regional Water Providers Consortium video shows how to use a water meter to check for leaks.

Groundwater Wells

Well owners are independently responsible for monitoring and maintaining their wells.  There are many agencies and resources available to help.  From well servicers to local groundwater conservation districts and national agencies, here is a list of useful links.
