Review of Plans for Public Water Systems

Information about TCEQ reviews of technical plans before construction begins. List of plans under review with estimated review timelines.

No person may begin construction of a public drinking water supply system unless the TCEQ determines that the system can supply safe drinking water in adequate quantities and is financially stable and technically sound. Public Water System operators must notify the TCEQ of any proposed new system or significant changes to existing systems.

TCEQ reviews are based on the requirements in the Rules and Regulations for Public Water Systems Adobe Acrobat PDF Document in the Texas Administrative Code, Title 30, Chapter 290, Subchapter D.

Suggested Construction Notes to Expedite Plan Review

Radionuclide Testing Required for Well Completion

Several areas of Texas have groundwater with elevated radionuclide levels. If you are drilling a well in a county where radionuclide testing is required, you must conduct radionuclide testing for interim approval.

For guidance on conducting this testing properly, see How to Conduct Radionuclide Testing for Well Completion Interim Approval.

Status of Reviews in Progress

To view the status of plan reviews, go to the Main IWDD Report Form. Select "PWS Plan Review Report" from the drop-down menu, then choose "Select Report."

When you see the question "Are you ready to process the report?" select "Yes." It may take several minutes for the report to download.

The report will show all plans that have been submitted and whether they (1) have not yet been assigned, or (2) are currently under review. The plans are listed alphabetically by the name of the water system.

If you have questions about the status, please e-mail us at and refer to your project's log number.
