Instructions for Texas Drinking Water Watch

How to use the Drinking Water Watch database to find analytical results, schedules, and violations to learn more about the quality of your drinking water and your public water system's compliance with state regulations.

Introduction to Drinking Water Watch

Texas Drinking Water Watch (DWW) is a database that drinking water operators and the public can use to find information about public water systems. The resources on this page will show you how to find the most useful and commonly requested data in DWW.

Here are some helpful tips to get you started:

  • When you search for a public water system enter the PWS ID or system name, but not both, because that will not provide any results. You can search a partial name or narrow down the search by using system type, county, or source-water type.
  • Use the yellow links at the top of each screen to reach all the areas in the database.
  • If you are looking for something specific press Ctrl and F on your keyboard at the same time. Then type the word or abbreviation into the Find box.

To ensure that communication and compliance information is addressed to the appropriate personnel at your Public Water System, it is important to notify TCEQ of any changes to the contact information. These requests should be sent to PWSInven@tceq.texas.gov.
