Texas Water Service Boundary Viewer (TWSBV) Editor
The Texas Water Service Boundary Viewer (TWSBV) is now open for editing until July 1, 2024.
The Texas Water Development Board (TWDB) has developed a statewide public water system service area mapping application called the Texas Water Service Boundary Viewer (TWSBV) through a grant from the U.S. Geological Survey (USGS) Water Availability and Use Science Program. While several water system mapping applications exist in the state, they do not necessarily represent the actual retail water service areas or include all the public water systems (PWS) within the state. This mapping application strives to collect and provide the most up-to-date and best data available on the water service areas for all community PWS within Texas.
For more information on the TWSBV application, please visit the FAQ and Guidance Video Page
The application is available to the public to view the water service boundaries and related reports including historical water use and Texas Commission on Environmental Quality public water system information. No sign in is needed.
User Guide for Public
The online water use survey will prompt active community public water systems to update or verify their service boundaries annually upon completion. The boundaries will reflect the current retail water service areas using the TWSBV application. The TWSBV application for editors is accessible directly through the TWSBV site as well as through the online water use survey. Editors are approved users of the water use survey that can make updates to their boundaries in the TWSBV application. Editors will access the TWSBV application through the Okta portal.
Chrome is the preferred browser.
