Irrigation in Austin: Hiring a TCEQ-Licensed Irrigator

Irrigation work in Austin has to be done by a TCEQ-licensed irrigator, because Texas law keeps the selling, designing and installing of sprinkler systems with people the state has tested. Austin Pro Landscape helps you scope the job first, so the quotes you collect are comparable. Call (512) 690-4912 or request a free quote.

This page is a planning guide, not a price list. We don’t sell or perform sprinkler installation, so you won’t find an install number here, and you shouldn’t trust one from anyone who hasn’t walked your lot. What you will find is the licensing path, what the state and the City of Austin expect, the questions that separate a solid quote from a vague one, and the order things happen in.

Who can legally design and install an irrigation system in Austin?

Only someone licensed by the Texas Commission on Environmental Quality. TCEQ’s licensing page says a person may not sell, design, install, maintain, alter, repair, service or inspect an irrigation system, or consult on those activities, unless TCEQ has licensed them. That applies in Austin and across Texas.

That one sentence from TCEQ shapes everything else on this page. It means the person who draws your zones, the person who sells you the system and the person who connects it to your water supply all fall under the state’s licensing rules. It also means that a friendly handyman or a general landscaper with a trencher isn’t the right hire for the irrigation part of your project, however good their lawn work is.

TCEQ’s rules are in Title 30 of the Texas Administrative Code, Chapter 344, and the same page notes that some people are exempt from the licence requirement. Those exemptions are listed in 30 TAC section 30.129, and TCEQ is clear that an exempt person still has to follow the Chapter 344 installation standards. If you’re ever unsure whether a particular person falls under an exemption, read that rule or ask TCEQ directly before you pay anyone.

What does a TCEQ irrigator licence actually cover?

TCEQ issues three related licences. A Landscape Irrigator can sell, design, consult on, install, maintain, alter, repair and service a system, including connecting it to a water supply. An Irrigation Technician works under a licensed irrigator’s supervision. An Irrigation Inspector verifies permits and checks that a system meets the rule.

• Landscape Irrigator (LI): the full licence. This is the person who can design your system and sell it to you.
• Irrigation Technician (IT): can connect a system to a water supply, including installing a backflow prevention device, but while connecting it must be under the direct supervision of a licensed irrigator.
• Irrigation Inspector (II): verifies that permits have been obtained, inspects the system, checks that the right backflow device is installed, and provides test results to the water purveyor.

To earn any of these, TCEQ says an applicant completes the required training, submits an application and a criminal history attestation, pays a $111 fee and passes the exam with at least 70 percent on each section. Licences run three years and then renew with continuing education: 24 hours for irrigators and inspectors, 16 for technicians. So a current licence tells you the person has been tested and is keeping up.

How do I check an irrigator’s TCEQ licence before I sign?

Use TCEQ’s own license search. The agency’s licensing page links an Individual Search, a Group Search and a Company Registrations search. Ask the irrigator for their name and licence number, look them up yourself, and confirm the licence is current and is the type that matches the job.

Don’t take a business card or a truck door as proof. Do the lookup before you sign, and keep a screenshot with the date on it. If the person quoting you is a salesperson, ask which licensed irrigator will actually design and supervise your system, and look that person up too.

TCEQ also requires licensed irrigators to have the seal and the license in physical possession while they work. Asking to see both on site is a fair request. A real irrigator expects it, and it takes ten seconds. If someone gets defensive about a licence check, that tells you what you needed to know.

What does the licensed irrigator have to handle on a new system?

The licensed side covers the design, the connection to the water supply, the backflow device, the permits and the inspection. Our role is the planning around it. Per TCEQ and Austin Water’s pages, permit verification, the right backflow assembly, test results to the water utility and the irrigator’s seal all sit with the licensed trades, not with the homeowner.

Here’s how the pieces line up, using only what TCEQ and the City of Austin publish:

That last row is the part most homeowners skip. An irrigator can design a perfectly legal system for a yard that’s about to change, and then you’re paying to move heads. Settling the yard first is cheaper than settling it after the pipe is in.

Why does Austin require a backflow assembly on an irrigation system?

Because a sprinkler system is a cross-connection between your yard and the drinking water supply. Austin Water explains that backflow can pull contaminants back into the public system when pressure drops, and it generally requires a backflow prevention assembly at the water service connection to each dedicated irrigation system.

Austin Water’s overview lists irrigation systems among the connections that typically need a backflow assembly, and says these devices are subject to annual inspection, maintenance, testing and reporting. It also says the assembly requirements are determined by plumbing inspections during the building permit process, and that any assembly installed must be a design approved and listed by the University of Southern California foundation for cross connection control research.

Three practical points follow from the City’s pages. First, the device has to match the hazard: TCEQ notes that where fertilizer, insect repellent or any other chemical is injected into an irrigation system, a reduced pressure assembly must be used. Second, the assembly has to be installed to the plumbing code the City has adopted. Third, an above-ground assembly needs freeze protection, which Austin Water specifically mentions because a hard freeze can crack one.

That freeze point isn’t theoretical in Central Texas. If you’re planning a system, ask where the assembly will sit and how it’ll be protected. Our Austin ice storm and drought guide covers what a hard freeze does to a yard and the plumbing in it.

Who tests the backflow assembly, and how often?

A tester licensed by TCEQ and registered with Austin Water. The City says assemblies in its distribution area must be tested by a licensed backflow prevention assembly tester, and that mechanical assemblies protecting against a health hazard are tested on installation and then at least once a year after that.

Austin Water’s tester page adds the paperwork side: each tester must submit a complete Test and Maintenance Report for every assembly within five calendar days of the test, and since July 25, 2022 that goes in through the City’s WEIRS database online, not on paper.

What that means for you as the owner: the annual test is a recurring line item in owning an irrigation system, not a one-time cost. Ask any irrigator you’re considering who tests the assembly, whether that person is registered with Austin Water, and whether the quote includes the first test. For questions about what your specific assembly needs, Austin Water’s Water Protection team lists a phone number, 512-972-1060, option 5, on its tester page.

What does our irrigation planning process look like, step by step?

It’s a homeowner’s process, and the licensed work sits in the middle of it. You settle what the yard needs, get comparable quotes from TCEQ-licensed irrigators, confirm permits and backflow, then watch inspection and testing happen before you sign off. Most projects run a few weeks from first walk-through to a running system, depending on permit and scheduling.

1. Walk the yard and decide what’s changing (about one visit). You and Austin Pro Landscape look at turf, beds, trees, slope and sun. You decide whether any beds are being added, removed or moved, because the pipe layout follows the plants.
2. Write the scope (a few days). One page: lawn zones, bed zones, trees on bubblers or drip, where the controller goes, and what’s out of scope. This is what every irrigator quotes against, so the bids line up.
3. Collect two or three quotes from TCEQ-licensed irrigators (one to three weeks). You choose who to invite. You verify each licence on TCEQ’s search before you take a bid seriously.
4. Compare the quotes line by line (a day or two). You check the same zone count, the same controller type, who pulls the permit, who tests the backflow assembly, and what happens if the City inspector wants a change.
5. Confirm permit and backflow plan (before work starts). The irrigator and the City handle the permit and plumbing inspection side. You confirm in writing who is responsible for what and where the assembly goes.
6. Schedule the work around the yard (varies). Trenching comes before sod, after hardscape. If a patio or wall is going in, the irrigation sleeves go in first. See our hardscaping planning page for how the pieces order themselves.
7. Inspection and backflow test (same week the system is finished). Inspection and the assembly test happen before you rely on the system. You make sure the test report is filed.
8. Final walk-through and controller handoff (about an hour). You see each zone run, learn the controller and set it to your watering day. Keep the paperwork in one folder.

What should I ask in an irrigation quote?

Ask for the irrigator’s name and TCEQ licence number, the zone count, the controller model, the backflow assembly type and who tests it, who pulls the permit, what’s excluded, and what happens if the inspector requires a change. A quote that can’t answer those in writing isn’t ready to compare.

• Licence: the name and number of the licensed irrigator responsible, so you can check it on TCEQ’s search.
• Zones: how many, and which are turf and which are beds. Drip and spray zones are different hardware and different run times.
• Controller: make and model, and whether it adjusts to weather. Austin’s one-day-a-week rule for automatic systems makes this matter more than it would elsewhere.
• Backflow: the type of assembly, where it goes, how it’s freeze-protected, and who tests it and files the report.
• Permits and inspection: who applies, who’s present at inspection, and what a failed inspection costs you.
• Exclusions: trenching through caliche, rock, existing sod repair, tree roots, extra heads. These are where a low bid grows.
• Paperwork: the zone map you’ll be handed at the end, and the controller schedule.

Write your questions down and send them to every bidder in the same message. You’ll learn as much from who answers clearly as from the numbers.

What affects what an irrigation project costs in Austin?

Lot size, zone count, how much of the yard is lawn versus beds, the soil you have to trench through, the controller you choose, the backflow assembly, and permit and inspection steps. Because those vary lot to lot, a fair number only comes from a licensed irrigator who has seen your yard.

We keep our own published landscaping ranges on the Austin landscaping cost guide, which shows where irrigation fits inside a bigger project budget. We don’t quote irrigation installation prices, and neither TCEQ nor the City of Austin publishes a standard rate, so any single figure you see online is somebody’s marketing, not a rule.

A few cost drivers are specific to this area. Central Texas soils are tight, often caliche and clay, and trenching through them takes longer and wears out equipment. Our Austin soil guide explains what you’re digging into. A system on a big sloped Hill Country lot in Lakeway or Dripping Springs needs more thought about pressure and runoff than a flat lot in Pflugerville or Hutto.

How do Austin watering rules change how I plan a system?

They decide how your controller has to be set. Under Austin Water’s Conservation Stage, as our watering rules page records it, automatic in-ground systems run one designated day a week, before 10 a.m. or after 7 p.m. Hand watering and tree bubblers aren’t limited. Stages change with reservoir levels, so confirm the current one with Austin Water.

The one-day rule changes what a good design looks like. If every zone has to finish inside a single morning or evening window, then zone count, run times and water pressure all matter more. A system with too many zones on one valve manifold may not get through its cycle. Ask the irrigator how long a full run takes at your lot’s pressure.

Our Austin watering rules guide lays out even and odd address days, and our watering restrictions page tracks stage changes. Austin Water says a variance from the restrictions can be granted in limited situations, case by case, and that new landscapes can be hand watered. If you’re planting in summer, raise that with the City early rather than after the plants are in.

Is drip or spray the better choice for each part of my yard?

Use spray or rotor heads on turf, which needs broad overhead coverage, and drip on beds, borders and tree rings, where water belongs at the root zone. Most Austin yards end up as a mix. The split matters because drip and spray need separate zones with different run times.

We cover the trade-offs in detail in our drip versus sprinkler guide for Austin. The short version from that guide: drip delivers water at the soil surface with very little lost to wind or evaporation, which suits an Austin July. Turf can’t practically be watered by drip, and drip that goes unmaintained fails quietly, so flushing lines and walking the beds after a cycle matters.

If you’re thinking about a lower-water yard overall, xeriscaping in Austin changes how much irrigation you need at all, and our irrigation water calculator helps you size how much water a zone actually uses.

What do typical irrigation projects look like around Austin?

They fall into a few recurring shapes. These are illustrations of how a homeowner scopes the job, not completed customer projects, and none of them carries an install price because that’s the licensed irrigator’s to quote after seeing the lot.

• A typical new-construction lot in Leander or Hutto: bare yard, sod going in, a few foundation beds. The scope is a turf zone set, a bed zone set on drip, a controller sized for a single watering day, and a backflow assembly placed where it’s protected from freezes. The decision that matters is getting sleeves in before any flatwork.
• A typical older yard in West Lake Hills or Bee Cave being replanted: existing system, new beds, mature trees. The scope is mapping what’s there, converting bed zones from spray to drip, adding tree rings, and replacing the controller. The irrigator needs to know the plant plan before touching the valves.
• A typical lawn conversion in Round Rock or Cedar Park: part of the turf is coming out for native and adapted planting. The scope is capping or re-zoning the turf lines and adding drip. Austin Water has rebate programs for conversions, so check what’s current before you start.
• A typical backyard project in Georgetown or Pflugerville: a patio or pergola is going in and the sprinkler lines run right through it. The scope is rerouting lines before the hardscape crew arrives. Pair this with landscape design planning so the plan shows both.

When is the best time to start an irrigation project?

Plan in winter and early spring, build in fall or early spring if you can. Our Austin landscaping calendar treats fall as the best window for new installs because roots establish before summer heat. Starting the planning in January means quotes and permits are done before the busy season.

The reason isn’t only the plants. Planning ahead also gives you time to collect quotes, check licences and settle permits without a deadline pushing you. Our Austin landscaping calendar shows how the seasons line up for turf, beds and tree work.

If you’re on a tight deadline, say so in the scope. A system installed in July has to share a hot, dry window with new sod or plants that need extra water, and one watering day a week won’t cover that. Hand watering is allowed any time, and it’s often the bridge for new plantings.

What if my existing system has problems, not a full replacement?

Repair, service and alteration of an irrigation system fall under the same TCEQ licensing rule as installation, so the same licence check applies. Start by identifying what’s actually wrong: a broken head, a stuck valve, a controller that ignores the weather, or a zone that never gets enough pressure.

Our sprinkler repair page for Austin lists the common failure points. For a system that mostly works, targeted changes usually make more sense than starting over: swap spray heads for efficient nozzles, move a bed to drip, replace a controller. Describe the symptoms to the irrigator in writing and ask them to tell you which fix addresses which symptom.

It’s also worth checking whether your backflow assembly has a current test on file. Austin Water says assemblies in its program are subject to annual testing and reporting, and a system that has gone years without a test report is a good reason to call a tester registered with the City.

What happens if an unlicensed person does the work?

You carry the risk, and the state treats it as a violation. TCEQ’s landscape irrigation page says complaints about unlicensed irrigators can be filed in municipal and justice of the peace courts, citing Texas Occupational Code section 1903.256, and that TCEQ also takes complaints about licensed irrigators.

The practical problem for a homeowner isn’t the citation. It’s that the permit, the inspection and the backflow test are all steps the licensed trades are responsible for, and work done outside that path leaves you to sort out the gaps yourself. Verifying the licence up front takes a few minutes.

Which Austin-area neighbourhoods and suburbs does this planning help cover?

We help homeowners scope irrigation projects across Austin and the surrounding area, including Round Rock, Cedar Park, Pflugerville, Georgetown, Leander, Hutto, Manor, Bee Cave, West Lake Hills, Lakeway, Dripping Springs, Kyle, Buda and San Marcos. Water utilities and permit offices differ outside the city, so confirm local rules.

Several of these have their own page on our site: Round Rock, Cedar Park, Pflugerville, Georgetown, Leander, Lakeway. Our areas we serve page has the full list.

One caution applies outside the Austin city limits. The City of Austin pages quoted above describe Austin Water’s program. A home in a suburb may be on a different utility or a well, with a different backflow program and a different permit office. TCEQ’s licensing rules stay the same statewide, but who you register tests with and who inspects can change. Ask the irrigator which utility your address sits in before you assume anything.

Where do I start?

Start with the yard, not the irrigator. Decide what’s staying, what’s changing and what you want it to look like, then get written quotes from TCEQ-licensed irrigators against that one scope. Call (512) 690-4912 or send a free quote request and we’ll help you put the scope together.

Before you sign anything, check the licence on TCEQ’s search, confirm who handles the permit and the backflow test, and keep a copy of the test report. Those three steps are the whole difference between a system that’s on the record and one that isn’t.
