Groundwater Permitting in Texas

Groundwater use in Texas is primarily regulated by local Groundwater Conservation Districts (GCDs). This page explains when permits are required and how to find your local district.

Do I Need a Permit?

  • Yes - If you're in a GCD, you may need a permit to drill or pump.
  • No - If you're outside a GCD, permits may not be required, but the Rule of Capture still applies.

Use the GCD Index to find your local district and its permitting rules.

Exception: Is your well a public water supply well?

Even if your well is on private property, it may be considered a public water supply (PWS) well if it serves:

  • 15 or more connections
  • Or regularly serves at least 25 people for at least 60 days a year

If your well meets these criteria, it must be registered with the TCEQ's Water Supply Division.
