Texas Licensed Irrigator on staff
Irrigation design, sealed in-house by a Texas Licensed Irrigator
In Texas, designing, installing or servicing an irrigation system for someone else takes a license from the TCEQ. Our Licensed Irrigator is on staff, so the irrigation plan is drawn, sealed and coordinated with the landscape, the site and the building by the same team.

What goes into an irrigation plan
Every new system needs a site-specific plan, drawn to scale and sealed, signed and dated by the Licensed Irrigator. It shows the property lines, buildings, beds and watered areas, each zone with its valve size and flow, the controller and sensors, the equipment specifications and the design pressure. The plan stays on site during installation and becomes the as-built drawing at the end.
Designed to save water
- Zones split by plant type, sun and soil
- Matched watering rates within each zone
- Head spacing within the manufacturer's limits
- No spray on walks, drives or walls
- Drip and bubblers for beds, planters and trees
- A rain or moisture shut-off sensor on every automatic system
- Backflow prevention, a master valve and an isolation valve
What we design
- Retail centers, offices and parking lot islands
- Schools, parks and sports fields
- Custom homes, backyards and pools
- Drip for beds, planters and trees
- Smart controllers and rain sensors
- Irrigation that goes with your landscape plan
Permits and inspections
Texas cities with 20,000 or more people must require an irrigation permit and inspect the installation. In Houston, the permit is pulled by a licensed irrigator or master plumber registered with the city, and the installation is inspected on site against TCEQ standards. We plan for the inspection from the first zone.
Some of our work
How it works
- ConsultA free first meeting and a site visit. We listen for what you need, your budget and your timeline.
- We design itConcept plans, elevations and renderings you can react to early, while changes are still easy.
- We engineer itStructure, MEP, site and irrigation, engineered and checked against code. When a job needs it, such as industrial or complex commercial work, we engineer it with our partners.
- PermitA complete, coordinated drawing set, ready for permitting and bidding. We handle the permit process for you and expedite it until it is approved.
- We build itWe build it, or we support your builder until it stands.
Questions
Do I need a licensed irrigator to design my sprinkler system?
In Texas, anyone who designs, installs or services an irrigation system for someone else needs a TCEQ license, with a few exceptions, such as homeowners working on their own property. Our Licensed Irrigator designs and seals the plan.
Do you design commercial irrigation?
Yes: retail centers, offices, schools, parks, sports fields and parking lot islands, laid out with the landscape plan and the site.
Does the plan include backflow prevention?
Yes. Every plan shows the backflow prevention device for the connection, a master valve after it and an isolation valve between the meter and the backflow device.
Can you take it through construction?
Yes. A1 is a design-build company, so we can carry the project from the sealed plan through construction, or hand the plan to your installer.
