Water and Sewer Utilities


The Public Utility Commission of Texas (PUCT) is responsible for the general supervision and oversight of water and sewer utility regulation. This supervision and oversight includes processing applications for certified retail water and sewer utility service areas. The PUCT also regulates retail water and sewer rates with original jurisdiction over certain rate functions and appellate jurisdiction over others.

The PUCT is also responsible for determining whether utilities have the financial and managerial capability to provide continuous and adequate water or sewer service to the public. The PUCT also offers assistance to consumers and provides oversight of submetering and allocated utility billing practices.
