(Questions 1–15)
Q1: Which Texas state agency serves as the governing body for irrigation licensing in
Texas?
A. Texas Department of Agriculture
B. Texas Commission on Environmental Quality (TCEQ) [CORRECT]
C. Texas Water Development Board
D. Texas Department of Licensing and Regulation
Correct Answer: B
Rationale: The Texas Commission on Environmental Quality (TCEQ) is the sole
governing body for irrigation licensing in Texas, administering 30 TAC Chapter 344, the
Irrigator Advisory Council, licensing examinations, and enforcement of all
irrigation-related regulations statewide.
Q2: The Irrigator Advisory Council (IAC) is composed of:
A. 6 licensed irrigators only
B. 9 members: 6 licensed irrigators and 3 public representatives appointed by the TCEQ
commission [CORRECT]
C. 12 members: 9 licensed irrigators and 3 public representatives
D. 15 members, all appointed by the Texas Legislature
Correct Answer: B
Rationale: The IAC consists of exactly 9 members: 6 licensed irrigators providing
industry expertise and 3 public representatives ensuring consumer protection, all
appointed by the TCEQ commission. This balanced composition ensures regulatory
decisions consider both professional and public interests.
,Q3: A licensed irrigator is asked by a homeowner to test their backflow prevention
assembly after installation. The irrigator should:

B. Refuse, as licensed irrigators are prohibited from testing backflow devices
[CORRECT]
C. Perform the test only if they also hold a plumbing license
D. Refer the homeowner to the TCEQ Austin office for testing
Correct Answer: B
Rationale: Texas regulations explicitly prohibit licensed irrigators from testing backflow
prevention assemblies. Backflow testing must be performed by a separately licensed
Backflow Prevention Assembly Tester (BPAT). This restriction exists because backflow
testing requires specialized gauges, training, and certification to protect public water
supplies.
Q4: Every written irrigation contract in Texas must contain which mandatory statement?

C. "All irrigation systems carry a 5-year warranty."
D. "Payment is due upon completion of installation."
Correct Answer: B
Rationale: TCEQ 30 TAC Chapter 344 mandates that all written irrigation contracts

consumers know the regulatory authority and where to verify licensure or file
complaints. Failure to include this statement is a regulatory violation.

B. A permanently installed assembly for controlled distribution and conservation of
water for landscape, dust reduction, or erosion control [CORRECT]
C. A temporary hose-end sprinkler used for residential watering
D. Any plumbing fixture connected to municipal water

controlled water distribution for landscape, dust reduction, or erosion control.

applications are excluded from irrigation system regulation.

B. The technician must receive approval from the licensed irrigator before altering the
irrigation design [CORRECT]

B. The homeowner may install the system without a license on their own property
[CORRECT]

D. The system cannot be connected to municipal water without a license
Correct Answer: B

compensation. Homeowners may install systems on their own primary residence
without a license. However, all systems must comply with plumbing codes, backflow
prevention requirements, and local regulations regardless of who installs them.

services. This is:

accountability. There are no exceptions based on job size or license tenure.

licensed irrigator should:
A. Ignore the situation to avoid conflict
B. Report the unlicensed activity to TCEQ [CORRECT]
C. Confront the competitor directly

licensed professionals.

without legal authorization [CORRECT]
