Licensed irrigators that are no longer practicing landscape irrigators may request TCEQ to withdraw their "active" irrigation status. Irrigators that hold an "Honorary License" are not required to take continuing education courses or pay fees.

To qualify for an "Honorary License" an irrigator should submit to the TCEQ the following information:

  • a request signed by the irrigator or if the irrigator is deceased, a family member;
  • the license number;
  • the date issued; and
  • mailing address.

Irrigators, companies, or family members may contact an Irrigator Advisory Council member by e-mail at Please indicate Irrigator Advisory Council in the subject line. Local associations may be contacted for assistance in assembling the needed information.

TCEQ will verify the information, remove the "active" status, and issue a certificate.

If an irrigator later decides to become "active", the irrigator will have to meet all current TCEQ requirements.
