Irrigation near you

Understanding the components makes a quote readable, because most of what you are paying for is buried and most of what fails is one of six things.

A good installation starts with measurements rather than a parts list: the available pressure and flow at the meter, the shape and slope of the yard, sun and shade, soil type, and the separate water needs of lawn, beds and trees. Those numbers set the number of zones. A system designed without them is the usual reason one zone floods while another never wets the soil more than an inch down, and no amount of controller programming fixes a hydraulic mistake afterwards.

The install itself is trenching, laying mainline and lateral pipe, setting valves in accessible boxes, placing heads so their spray patterns overlap, making the supply connection with the required backflow protection, running wire back to the controller, then flushing, pressurizing and adjusting every head. The part that decides how the system performs for the next decade is the last hour: the walkthrough where each zone is run in front of you, run times are explained and written down, and you are shown where the shutoff, the valves and the controller manual are.

Because an irrigation system connects to the drinking water supply and then sits in soil, fertilizer and pet waste, the connection point is the regulated part. Texas separates the roles precisely: a licensed irrigator may sell, design, consult, install, maintain, alter, repair or service a system, including the connection to a public or private water supply; an irrigation technician may connect the system to a water supply, including installing a backflow prevention device, and may work on a system under a licensed irrigator's supervision; and an irrigation inspector determines whether the system complies with the rules and whether the appropriate backflow prevention device is installed. Your own state may regulate this through plumbing licensing instead, and your water utility may require a tested backflow assembly regardless.

Trenching brings a second obligation that applies everywhere. 811 is the national number to call before digging, and the notice period is set by state law: Washington's utilities commission tells excavators to give two to ten full business days notice before the scheduled work-to-begin date, notes that the service is provided free to the excavator and that state law requires underground utilities to be located before digging, and requires marks to be maintained for 45 days or until the project is complete, whichever is shorter. Utilities repeat the same instruction to homeowners, with PG&E asking customers to call 811 at least two working days before digging or planting and noting that crews mark underground utilities for free. Irrigation trenches, valve boxes and even deep planting holes all qualify, so confirm the ticket was filed and that the marks are on the ground before the trencher arrives.

The oldest controllers do one thing: run a fixed schedule until someone changes it. That is why a system installed for a new lawn is often still watering it as though the sod were laid last week, through rain, through cool weather and through the seasons. The replacements are smarter in two different ways. EPA explains that weather-based irrigation controllers use local weather and landscape conditions to tailor watering schedules, while soil moisture-based irrigation controllers monitor moisture levels in the soil to prevent irrigation when water is not needed.

The savings are real but conditional. EPA states that replacing a standard clock-based controller with a WaterSense labeled irrigation controller can save an average home up to 15,000 gallons of water annually, and that with proper installation, programming and maintenance, homeowners and businesses can use labeled controllers instead of clock-based controllers and no longer worry about wasted water. EPA also notes that a well managed system can reduce a household's irrigation water use by 15 percent, or nearly 7,600 gallons annually. A smart controller installed on a badly zoned system with misaimed heads simply automates the same waste, so pair the upgrade with an audit rather than treating it as a substitute for one.

EPA frames irrigation maintenance around four checks, and they are the same four a professional runs at the start of a season. Inspect, because missing or broken sprinkler heads can be hard to find when most systems run overnight or early in the morning. Connect, because leaks occur at the joints between sprinklers and piping, and leaking joints can also signal too much water pressure or particles in the water. Direct, because any sprinklers spraying onto driveways, sidewalks or walls should be turned toward the landscape. Select, because a WaterSense labeled controller uses local weather data or soil moisture to adjust the schedule automatically.

An audit goes further than a visual check. A professional certified through a WaterSense labeled program in system audits measures how evenly each zone applies water, checks pressure and head spacing, and converts the result into run times per zone rather than one number for the whole yard. Ask for the findings in writing, including which heads were replaced, what the pressure readings were, and the recommended schedule by season. EPA's directory of certified professionals is searchable by ZIP code and by whether the pro is available for hire, which is a practical way to confirm a credential a company mentions.

Across the northern half of the country the season ends with winterization: shutting off the supply, draining or blowing out the lines and protecting the backflow assembly, because water left in a lateral or in an assembly body can split it when it freezes. Spring start-up is the reverse, pressurizing slowly, walking every zone and replacing what the winter and the mower broke. In the mildest parts of the South and Southwest, systems run year round and the seasonal work is rescheduling rather than draining, though a hard freeze warning still means protecting exposed components.

Schedules are also set by rules rather than weather in much of the country. Many water utilities assign watering days and hours by address, restrict daytime irrigation outright, and tighten the rules further during drought stages, with separate allowances for a newly installed lawn while it establishes. Those rules change how a system should be designed as well as programmed: fewer permitted days pushes a design toward drip in beds, larger mulched areas, plants grouped by water need and turf limited to the part of the yard that is actually used. Check your own utility's current stage before agreeing to a schedule, and tell the contractor what it says.

Two irrigation bids diverge mainly on design, not on sprinkler brands. The variables are the irrigated area and how many zones the available pressure and flow force it into, the mix of spray, rotor and drip, the type of backflow assembly your utility or state requires and who is licensed to install it, trenching conditions such as rock, roots and existing hardscape, the controller and any sensors, and whether the price includes a documented walkthrough, a season of adjustments and a winterization visit. For repairs, the drivers are how buried the fault is and whether the diagnosis is included in the price.

LokalMatch is where it begins. You describe the property once: the size of the area to be watered, whether you want a new system, an extension or a repair, what the lawn and beds need, and what your utility allows. Irrigation contractors serving your area receive the request, and the ones interested contact you. Pros pay for the requests they receive, and homeowners use the service at no charge. LokalMatch does not install or repair irrigation systems, does not set prices, and does not vet, rank or recommend any contractor, so verifying the state license where one is required, the backflow requirements of your utility and the written scope stays with you.
