Texas Water Utilities (TWU) rates are based on the cost of providing services to our customers. The rules under which we operate, and the prices charged for water and wastewater services, are approved by the Public Utility Commission of Texas (PUC).
We make available for our customers a tariff book, inclusive of rates for background information, as required by the PUC. Tariffs list out the rates and fees we charge as approved by the PUC. Tariff revisions are filed with the PUC and comply with Texas PUC Chapter 24 Rules. The most recent rates are posted as soon as official documents are available to us from the PUC. Below are the tariffs for all of TWU’s operating utilities; please contact our Customer Service team if you're uncertain which tariffs apply to you.
For more information on your rates and upcoming rate cases, see the Rates & Regulations postings on our News page. For more general information on how utilities are regulated, please visit the PUC website.
