Building a new home in the DFW metroplex is an exciting milestone, and one of the smartest decisions you can make during the construction process is to plan your irrigation system from the very beginning. Installing irrigation during new construction is significantly easier, more affordable, and produces better results than retrofitting a system after the landscaping is in place. Whether you are building in Plano, Frisco, Allen, McKinney, or anywhere else in North Texas, here is what you need to know about designing an irrigation system for your new home.
The biggest advantage of installing an irrigation system during new construction is timing. Before sod is laid, before flower beds are planted, and before hardscape like patios and walkways are poured, the ground is open and accessible. Trenching for irrigation pipes is fast, clean, and inexpensive when there is no existing landscape to work around. Retrofitting a system later means cutting through established lawns, digging around mature root systems, and potentially damaging driveways or patios to run pipe underneath. The cost difference is substantial — installing during construction typically saves 20 to 30 percent compared to a retrofit installation on the same property.
Building codes in many North Texas cities require or strongly encourage irrigation systems in new residential construction. Plano, Frisco, and Allen all have water conservation ordinances that favor efficient irrigation, and some HOA communities mandate that an irrigation system be installed before the final landscaping inspection. Getting your system designed and installed during construction ensures you meet all requirements without delays.
A well-designed irrigation system starts with a thorough evaluation of the property. Your irrigation designer will review the lot survey, landscape plan, soil type, water pressure, and available flow rate from the water meter. In North Texas, most residential water meters provide between 15 and 25 gallons per minute, which determines how many sprinkler heads can run simultaneously on a single zone. The designer divides your property into zones based on plant type, sun exposure, soil conditions, and slope.
Turf areas get their own zones with matched-precipitation-rate spray heads or rotary nozzles that deliver uniform coverage. Flower beds and shrub borders are typically placed on separate drip irrigation zones that deliver water directly to the root zone. Trees may have their own dedicated drip emitters. Each zone is designed so that all heads within it have similar water requirements and precipitation rates, ensuring even coverage without overwatering some areas and underwatering others.
A complete irrigation system for a new construction home includes several critical components. The backflow preventer is required by Texas code and prevents irrigation water from flowing back into the municipal water supply. It is typically installed near the water meter or on the side of the house. The valve manifold houses the solenoid valves that control each zone — it is usually placed in an accessible valve box in the yard. The main line connects the water supply to the valve manifold, and lateral lines run from each valve to the sprinkler heads in that zone.
The controller is the brain of the system. For new construction, we strongly recommend a Wi-Fi-enabled smart controller like the Rachio 3 or Hunter Hydrawise. These controllers adjust watering schedules automatically based on local weather data, which saves water and keeps your landscape healthier. They also allow you to control and monitor your system from your phone, which is especially convenient for new homeowners still learning their property's watering needs.
Spray heads, rotary nozzles, and rotors are selected based on the size and shape of each zone. Small, narrow areas use spray heads with fixed patterns. Medium areas use rotary nozzles (like Hunter MP Rotators) that apply water slowly and evenly. Large open areas use gear-driven rotors that throw water 25 to 50 feet. Mixing head types within a zone creates uneven application, which is why proper design matters so much.
North Texas clay soil is a critical factor in irrigation design. Clay absorbs water slowly — typically 0.2 to 0.5 inches per hour — and if water is applied faster than the soil can absorb it, the excess runs off and is wasted. A well-designed system accounts for this by using low-precipitation-rate nozzles and programming cycle-and-soak schedules that give the soil time to absorb each application. The system designer should also consider seasonal factors: your watering needs in July when temperatures exceed 100 degrees are very different from March when mild temperatures and occasional rain supplement irrigation.
New construction is also the ideal time to address drainage. Your irrigation designer can coordinate with the drainage plan to ensure that sprinkler zones do not contribute to standing water problems. In many cases, the irrigation and drainage systems can share trenches, reducing excavation costs. French drains, channel drains, and downspout discharge lines should be designed as an integrated system alongside your irrigation to protect your foundation, prevent erosion, and keep your yard dry between waterings.
Communication with your home builder is essential. The irrigation system should be installed after rough grading is complete but before final grading and sod installation. Your builder needs to know where the water meter connection will be tapped, where the controller will be mounted (usually in the garage or on an exterior wall near an electrical outlet), and where the backflow preventer will be located. A good irrigation company will coordinate directly with your builder to schedule the installation at the right point in the construction timeline.
For a typical new construction home in the DFW area with a lot size of 7,000 to 12,000 square feet, a professionally designed and installed irrigation system ranges from $2,500 to $5,000 depending on the number of zones, head count, controller type, and whether drip irrigation is included. This is a fraction of the cost of the landscaping it protects and typically pays for itself within two to three years through water savings compared to hand watering. Many builders offer irrigation as an upgrade or allowance item, so ask early in the process to include it in your construction budget.
