Licensed irrigation installs in Texas: permit, sealed plan and inspection.

Texas regulates landscape irrigation through the Texas Commission on Environmental Quality (TCEQ), under 30 TAC Chapter 344. The chapter makes the licensed irrigator responsible for the permits, the sealed plan, the backflow assembly and the handover documents, and larger cities check that trail.

An assistant can keep that trail in order: one record per install, each document's status, each date that starts a clock, and what is still missing before the inspector arrives. It never seals, signs, submits or decides. The design is the licensed irrigator's, the test result is the licensed tester's, and whether the system passes is the inspector's call. Texas is the only example here; this is not legal advice, and the irrigator confirms the current rules with TCEQ and with each city.

These rules were read in TCEQ's compilation of Chapter 344, which reflects the July 2020 amendments; TCEQ's history page lists a quadrennial review in January 2024 and no amendment since. The Texas Secretary of State publishes the official text, and local permit and inspection requirements vary by city, so the owner confirms both.

The City of College Station's irrigation page, as checked on 16 October 2026, lists four kinds of installer: a homeowner working on their own homestead, an irrigator holding a valid TCEQ irrigator license, a plumber licensed by the Texas State Board of Plumbing Examiners, and a licensed engineer, registered architect or registered landscape architect when the work is incidental to their profession. The city notes that since 1 September 2011 an installation by anyone else violates section 1903.256 of the Texas Occupations Code and may result in a Class C misdemeanor. TCEQ's landscape irrigation page adds that complaints against an unlicensed irrigator can be filed in municipal and justice of the peace courts, and that officers can issue a ticket.

The homeowner exemption is narrower than it sounds. Under 30 TAC §344.30(h), an owner irrigating their own home needs no license but must still meet the standards on spacing, pressure, spraying over impervious surfaces, rain or moisture shut-off and the isolation valve, and cities or water districts may ask more.

Under §344.35(d), obtaining every permit and inspection the install needs is the licensed irrigator's responsibility, and §344.24(c) requires cities of twenty thousand people or more to check that the irrigator who designs and installs a system holds a valid license and has a permit before work starts. College Station asks for a building permit, a fee and an irrigation plan, reviewed and approved by its building department before the permit is issued. Other cities set their own process, so the owner confirms each one.

Section 344.61 sets the plan's minimum contents. It must be site-specific, drawn to scale and kept on the job site during installation, and it must carry the irrigator's seal, signature and date; the property's major features and the areas to be watered; a north arrow, a legend and the scale; each zone's flow measurement with its station number and valve size; the location and type of the controller and sensors; specifications for the components; and the design pressure. Changes made during installation are marked in red ink, and all changes end up on an as-built drawing.

The seal carries weight. Under §344.43, an irrigator signs their legal name, places the seal above the signature and dates the document, and a sealed document means the irrigator accepts professional responsibility for it. The plan, the contract, any change orders, the warranty and the maintenance checklist are all sealed, and the irrigator keeps a copy of each sealed document for three years.

Section 344.62 sets the minimum design and installation standards; the table summarizes those that shape a typical residential layout. Meeting them is the licensed irrigator's design choice, and a tracker can only record that the irrigator has confirmed each one.

Section 344.52(c) makes the irrigator responsible for having the backflow prevention assembly tested before it is placed in service, and for getting the results to the local water purveyor within ten business days of the test. College Station adds that the test is done by a licensed backflow tester. That gives each job two dates: the test, and the purveyor's deadline.

Annual testing after the install is a separate cycle on the water supplier's calendar, covered in the series' backflow testing article for plumbing companies.

College Station requires an inspection when the work is complete. Under §344.37, the irrigation or plumbing inspector checks that the permits were obtained and the installer is licensed, inspects the system against the chapter, and confirms that the right backflow assembly was installed and tested and that the results reached the purveyor. Whether a system passes is the inspector's decision alone.

Section 344.63 then requires four things from the irrigator or technician who supervised the install: a walk-through with the customer; a maintenance checklist that the customer is asked to sign and the irrigator signs, dates and seals, including a seasonal watering schedule; a permanent waterproof sticker on each automatic controller with the irrigator's name, license number, company, telephone number and warranty dates; and the plan or as-built drawing showing what was actually installed.

Under §344.71, an install contract is written, signed by both parties and sealed, and names the irrigator, license number, business address and telephone with TCEQ's regulatory statement; estimates, bids and invoices for installs and repairs carry the same details. Under §344.38, records are kept for three years and produced within ten business days when TCEQ or the local authority asks.

Under Aevrion's design the owner creates a Paperwork Bot in Grok Bot, a named Bot on a persistent cloud computer whose only job is install records. Each document goes into the Bot's conversation or a job folder it can read, and the Bot returns a reviewable status sheet per job, as the documentation recommends for consequential work: what it found, what it inferred, what is waiting and what is missing, each tied to its file. Its memory is never the record; the job folder is.

Permit and purveyor portals ask for logins, and the documentation hands passwords and verification codes to a person through a takeover of the computer, so a person signs in and submits. Reading the company's job-management software would be a custom integration, or supervised browser use where the vendor permits it, subject to testing.

Based on the Grok Bot documentation at docs.x.ai as checked on 15 October 2026. The trade examples are Aevrion's illustrations, not documented Grok Bot use cases.

For the install paperwork as a whole, the readiness assessment gives a quick first reading. Anyone can use it without charge; it judges a single workflow across twelve dimensions and reports a result on the spot, listing blockers and a next step. If sealed plans and test reports sit in different trucks and inboxes, expect data availability to score low; a low score on security and compliance readiness would cap the result. With a usable score, Aevrion Ops can shape the Paperwork Bot, its approval points and any software connection the vendor's API or terms allow, once tested, around how the licensed irrigator already works.

1. Texas regulates landscape irrigation under 30 TAC Chapter 344, and cities of twenty thousand or more check the irrigator's license and permit before installation.
2. The plan is site-specific, to scale, on site during the install, and sealed, signed and dated by the licensed irrigator, who keeps sealed documents for three years.
3. Design standards cover spacing, pressure, matched precipitation, no spray over impervious surfaces, rain or moisture shut-off and an isolation valve.
4. The backflow assembly is tested before service and results reach the purveyor within ten business days; annual testing is a separate cycle.
5. An assistant can track every document and date, but the irrigator seals, the tester records, the inspector decides and a person submits.
