Landscape Irrigator, Irrigation Technician and Irrigation Inspector Licensing Overview

State Regulations:

A person may not sell, design, install, maintain, alter, repair, service or inspect an irrigation system—or consult in these activities—in this state, unless the person is licensed by the TCEQ. While connecting an irrigation system to a water supply, a licensed irrigation technician must be under the direct supervision of a licensed landscape irrigator.

  • Landscape Irrigator (LI) can sell, design, consult, install, maintain, alter, repair, or service an irrigation system, including the connection of such system to a private or public, raw or potable water supply or any water supply. This includes water wells in unincorporated areas of the state.
  • Irrigation Technician (IT) can connect a landscape irrigation system to a water supply, including installing a backflow prevention device; and may maintain, alter, repair, service, or direct the installation of an irrigation system under the supervision of a licensed irrigator.
  • Irrigation Inspector (II) are responsible for verifying that permits have been obtained. They can inspect the irrigation system, determine if the irrigation system complies with the rule requirements, determine if the appropriate backflow prevention device is installed, provide test results to the water purveyor, and investigate complaints.

To become licensed as a Landscape Irrigator, Irrigation Technician, or Irrigation Inspector, an applicant must:

  • complete the required training,
  • complete the TCEQ application,
  • submit a criminal history attestation,
  • pay the fee ($111), and
  • pass the applicable exam (minimum score of 70 percent for each section).

Once your approval letter has been received, contact your local computer-based testing center, for exam availability and registration.  Due to the six-hour length of the exam, not all CBT centers can accommodate more than 4-hour exams.  Please confirm with the CBT center before scheduling.

Note: If you hold a current Irrigation Technician license, it will be expired upon issuance of a Landscape Irrigator license.

Per 30 Texas Administrative Code §30.117 (1) An Irrigation technician is a person who works under the supervision of a licensed irrigator to install, maintain, alter, repair, service, or supervise installation of an irrigation system, including the connection of such system in or to a private or public, raw or potable water supply system or any water supply.

Therefore, obtaining the Landscape Irrigator license supersedes the need for the Irrigation Technician license.
