Historical Water Use Survey Data for Public Water Systems

This interactive data dashboard displays historical water use survey and estimate data by public water system in Texas from 2010-2020. There are two sections, Intake & Sales and Categorical Use and Connections. Using our interactive data dashboard, you can view how your water use has changed over time.

If you are a public water system, please review the information for your individual system. If you notice any missing information or errors in your water use data, please contact us by March 31st 2022 by emailing the Water Use Survey Team.

  • If you would like to see copies of your past water use surveys, please visit Historical Water Use Survey Records, 2000 and later and search using the survey number provided to you in the official survey letter.
  • If you see that your data is the exact same for two or more years, this indicates that the survey was not submitted for one or more years and the information from the previous submission was used as a placeholder.
