SECTION 1: Texas Water Codes and Regulations
Question 1
A homeowner in Texas wants to install an irrigation system connected to municipal
water. According to TCEQ regulations, which statement is correct regarding backflow
prevention?
A. No backflow prevention is needed for residential systems under 1 acre.
B. An atmospheric vacuum breaker is sufficient for all residential irrigation systems.
C. A backflow prevention assembly approved by the local water purveyor must be
installed at the point of connection.
D. Backflow prevention is only required for commercial properties.
Correct Answer: C Rationale: TCEQ and local water purveyors require
approved backflow prevention at the point of connection to protect the
public water supply from contamination. The type of assembly
required depends on the degree of hazard and local ordinance, but an
,approved assembly is mandatory for all connections to potable water
systems, regardless of property type or size.
Question 2
A landscape irrigator hires an unlicensed individual to install sprinkler systems under
the irrigator's supervision. According to Texas law, which action is permissible?
A. The unlicensed individual may design systems independently.
B. The unlicensed individual may install systems under the direct supervision of a
licensed landscape irrigator.
C. The unlicensed individual may sign permit applications on behalf of the licensed
irrigator.
D. The unlicensed individual may operate as a landscape irrigator using the company's
license.
Correct Answer: B Rationale: Texas law allows unlicensed individuals
to perform installation work under the direct supervision of a licensed
landscape irrigator. However, they cannot independently design
systems, sign permits, or hold themselves out as licensed irrigators.
The licensed irrigator retains full responsibility for the work.
Question 3
A client asks an irrigator to connect an irrigation system to a reclaimed water source.
What is the irrigator's primary regulatory concern?
A. Reclaimed water does not require any backflow prevention.
B. The system must include purple-colored piping and signage identifying non-potable
water, and cross-connections with potable water must be prevented.
C. Reclaimed water can be connected directly to the potable water line with a check
valve.
D. No license is required to install reclaimed water irrigation systems.
Correct Answer: B Rationale: Texas regulations require clear
identification of reclaimed water systems using purple piping and
,signage to prevent accidental use as potable water. Strict
cross-connection control is required to protect the public water supply.
A licensed irrigator is still required, and direct connection to potable
lines is prohibited.
Question 4
Which of the following is a violation of TCEQ landscape irrigator rules?
A. Installing a rain shut-off device on a new residential system in a municipality that
requires it.
B. Failing to provide the client with an as-built drawing of the irrigation system upon
completion.
C. Using a licensed plumber to install the backflow prevention assembly.
D. Submitting a system design to the local water purveyor for approval when required.
Correct Answer: B Rationale: TCEQ rules require licensed irrigators to
provide as-built drawings and documentation to clients upon
completion of the system. Failing to provide this documentation is a
violation. Installing rain shut-off devices, using licensed plumbers for
backflow assemblies, and submitting designs for approval are all
compliant actions.
Question 5
A landscape irrigator discovers that a competitor is advertising irrigation installation
services without a TCEQ license. To whom should this violation be reported?
A. The local police department
B. The Texas Commission on Environmental Quality (TCEQ)
C. The Texas Department of Licensing and Regulation (TDLR)
D. The Better Business Bureau

shut-off device?
A. Only when the client specifically requests one.
B. On all new automatic irrigation systems installed in Texas.
C. Only in counties that receive more than 30 inches of annual rainfall.
D. Only for commercial properties over 5 acres.
Correct Answer: B Rationale: Texas law requires rain or moisture
shut-off devices on all new automatic irrigation systems to promote
water conservation. This requirement applies statewide regardless of
property size, client preference, or local rainfall amounts.
Question 7
A licensed irrigator is designing a system for a property in a water district that has
implemented Stage 3 drought restrictions. Which design consideration is MOST
appropriate?
A. Design the system for maximum coverage regardless of restrictions.
B. Incorporate water-efficient components such as pressure-regulating heads, drip
irrigation for beds, and schedule compliance with watering day and time restrictions.
C. Advise the client to use the system at night to avoid detection.
D. Install a larger pump to increase pressure and reduce watering time.
Correct Answer: B Rationale: Licensed irrigators must comply with
local water restrictions and promote water conservation through
efficient design. Incorporating pressure-regulating heads, drip
