Irrigation Services in Texas

Climate & Irrigation Conditions in Texas

Texas irrigation operates under the strictest residential watering rules in the southern United States. Houston (Harris County), Dallas, Fort Worth, Plano, Frisco, and most North Texas metros run permanent Stage 2 restrictions limiting outdoor watering to two days per week assigned by address, with no watering between 10 a.m. and 6 p.m. April through October. San Antonio Water System tightens further during Edwards Aquifer drought triggers, dropping to one day per week when J-17 well levels fall below 650 feet. The climate split forces zone design choices. Gulf Coast 50-inch rainfall years still need supplemental irrigation through August and September dry windows, while Lubbock and Midland systems run year-round on 14-inch annual rainfall. Backflow prevention is mandatory under TCEQ 30 TAC Chapter 290 on any system tied to a public water supply, and most cities require an annual tested-and-tagged report from a licensed Backflow Prevention Assembly Tester (BPAT).

Common Irrigation Services in Texas

New sprinkler installs follow TCEQ minimum standards, including head-to-head coverage at 100 percent matched-precipitation-rate spacing, a master valve, a rain or freeze sensor wired to the controller, and a pressure-vacuum breaker or reduced-pressure backflow assembly sized to the meter. Drip-zone retrofits replace inefficient spray heads on planting beds with pressure-compensating emitter line at 0.9 gallons per hour, cutting outdoor water 30 to 50 percent and qualifying for SAWS and EAA rebates of up to $0.60 per square foot converted. Smart controllers running ET (evapotranspiration, the daily water loss from soil and plants) data through Hydrawise, Rachio, or Rain Bird LNK adjust runtime weekly and pass Stage 2 audit requirements. Repair calls peak in March (winter freeze-cracked PVC and ruptured rotors) and October (mole crickets chewing poly tubing). Pressure-regulated spray bodies installed at retrofit cut head misting by 30 percent in the 60 to 80 psi residential range.

When to Hire a Pro

Texas is one of the few states that licenses sprinkler work directly. Any new install, repair, or alteration to a permanent system tied to a potable water supply requires a TCEQ Licensed Irrigator (LI) or a Licensed Irrigation Technician (LIT) working under an LI's supervision. Verify license numbers on the TCEQ Licensee Database at tceq.texas.gov before signing a contract. Pulling the residential permit is the irrigator's responsibility, not the homeowner's. Confirm general liability of $1 million plus, since cross-connections that contaminate the potable supply trigger TCEQ enforcement and city water-shutoff orders. Backflow testing must be performed annually by a BPAT (Backflow Prevention Assembly Tester) and filed with the city water utility. Unlicensed installs leave the homeowner liable for fines up to $5,000 per violation under Texas Occupations Code Chapter 1903 and void coverage on any subsequent property damage claim.
