Sprinkler Systems in North Texas: Installation Cost, Repairs, and Water Restriction Rules

What does a sprinkler system cost by yard size in DFW?

New irrigation is priced by the number of zones, because each zone needs its own valve, wiring, and set of heads sized to the water pressure. A zone is simply a group of heads that run together, and a bigger or more varied yard needs more of them. Here are the typical installed ranges and common repair prices across the Frisco, Plano, McKinney, and Allen area in 2026.

Why does Texas require a licensed irrigator?

In Texas, it is illegal for an unlicensed person to install, sell, or repair an irrigation system connected to a public water supply. The Texas Commission on Environmental Quality (TCEQ) licenses irrigators, and the law exists because a sprinkler system ties directly into the drinking-water line.

That connection is why every legal system in North Texas must include a backflow prevention device, which stops lawn water, fertilizer, and pesticide from ever siphoning back into the house's potable water. A licensed irrigator is trained and accountable for installing that device correctly, filing the required plans, and meeting the state's design and testing standards. When you hire a licensed irrigator, you are buying a documented, code-compliant system rather than an anonymous crew's best guess, and if something is ever done wrong, there is a license on the line.

What does a well-designed North Texas irrigation system look like?

A good system matches the water delivery to what is actually growing, instead of blasting the whole yard the same way. That means separating the yard into zones by need and using the right head or emitter for each area.

• Turf zones on rotor or spray heads sized to throw even coverage without misting or fogging.
• Bed and shrub zones on separate valves, so beds are not drowned on the lawn's schedule.
• Drip irrigation in planting beds and around trees, delivering water slowly at the root zone where our clay soil can absorb it instead of shedding it as runoff.
• Head-to-head coverage, where each head's spray reaches the next, eliminating the dry brown arcs that show up in a poorly spaced system.
• A backflow preventer and a smart controller at the heart of the system, keeping it legal and efficient.

How do smart controllers keep you legal and cut the bill?

Most DFW cities, including Frisco, Plano, McKinney, and Allen, enforce watering restrictions that limit how often you can run your system, and those limits tighten into Stage 2 or Stage 3 during summer droughts. A smart, weather-based controller is the easiest way to stay compliant without babysitting the schedule.

Instead of running on a fixed timer, a smart controller pulls local weather data and evapotranspiration (ET) rates, essentially how fast the heat and wind are pulling moisture from your soil, and waters only when the lawn actually needs it. It automatically respects your assigned watering days, skips a cycle after rain, and shortens runs in mild weather. That combination keeps you inside the city's Stage rules and typically cuts irrigation water use meaningfully, which shows up directly on a summer bill where outdoor watering is the largest line item.

What are the signs your sprinkler system is wasting water?

A wasteful system quietly runs up your bill and can put you out of compliance without you noticing. Walk the yard while a cycle runs and watch for these symptoms.

• Runoff streaming down the curb or driveway, meaning water is applied faster than the clay can absorb it.
• Misting or fogging from the heads, a sign of pressure that is too high and blowing water away as drift.
• Uneven coverage, lush green next to dry brown arcs, pointing to clogged, misaligned, or wrongly spaced heads.
• A summer water bill that jumps far more than the season alone explains, often the first clue to a hidden leak or stuck valve.

How do you prep a sprinkler system for a North Texas freeze?

The annual North Texas ritual is protecting the system before the first hard freeze, because a cracked backflow device or split pipe is a spring repair nobody wants to pay for. Our winters swing from mild to sudden deep freezes, so the exposed above-ground components are the vulnerable point.

At minimum, shut off the water supply to the system and insulate the backflow preventer and any exposed above-ground piping with insulation covers or wrap. On systems with a proper drain setup, the lines can be drained or blown out with compressed air to clear standing water that would otherwise freeze and burst a pipe. A licensed irrigator can winterize the system in a single visit, and it is far cheaper than the post-freeze repair calls we field every February.
