How to start an irrigation business built on seasonal service plans

Irrigation looks like a plumbing-adjacent side service until you run it as a business. Then it becomes a route trade with a regulated water connection, a two-week stampede in spring, a hard deadline in fall, and a steady stream of broken heads and stuck valves in between. The companies that do well keep a record of every system they touch and sell an annual plan on the first visit. This guide covers the work, licensing and backflow rules, digging safety, equipment, pricing, how to find customers, and seasons in freeze and non-freeze climates.

What does an irrigation company do?

• Spring startups: turn the water on slowly, check every zone, adjust and replace heads, set the controller for the season.
• Repairs: broken heads and nozzles, leaking pipes, valves that stick open or will not open, wiring faults, dead controllers.
• Midseason checks and audits: coverage, pressure, overspray onto pavement, and schedule changes for summer heat.
• Winterization in freeze climates: blowing out lines with compressed air so water left in pipes does not freeze and crack them.
• Installs and retrofits: new systems for new lawns, drip zones for beds, smart controllers, rain and soil sensors, and conversions to more efficient nozzles.
• Backflow testing where your water utility requires periodic tests and you hold the tester certification.

Most new companies start with service and repair on existing systems, which needs less equipment and builds a customer list fast, then add installs. Landscape and lawn care companies often add irrigation because their customers already ask about it; see our landscaping startup guide.

What licensing and backflow rules apply?

Register the company, get an EIN, and open a business account first; our EIN guide covers the federal number. None of this is legal advice; rules differ by state, city and water utility.

State licensing. Some states license irrigation work as its own trade, others fold it into plumbing or contractor licensing, and some leave it to cities. Texas is a clear example: Texas Occupations Code §1903.251 requires a license from the Texas Commission on Environmental Quality for anyone who sells, designs, installs, maintains, alters, repairs or services an irrigation system, consults on one, or connects one to a water supply. Section 1903.002 lists exemptions, such as homeowners working on their own home and plumbers licensed by the state plumbing board. Do not assume your state is looser. Look it up on our state startup pages and call the licensing agency with a list of the services you plan to sell.

Backflow and cross-connections. An irrigation system connected to the house supply is a path from fertilized soil back into drinking water. The EPA's Cross-Connection Control Manual (2003 edition) defines cross-connections as actual or potential connections between a potable and non-potable supply, calls them a serious public health hazard, lists lawn sprinkler systems among fixtures with submerged inlets, and says all municipalities with public water supply systems should have cross-connection control programs. In practice, your state and the local water utility decide which backflow assembly an irrigation system needs, who may install it, and whether it must be tested on a schedule by a certified tester. Ask the utility before your first install, and consider getting tester certification if testing is required in your area; it is recurring work by definition.

Voluntary certification. The EPA's WaterSense program labels certification programs for landscape irrigation professionals that advance water-efficient practices. WaterSense labels certifications in three areas: irrigation design, installation and maintenance, and auditing. One of those tells customers and water utilities you know the efficient way to do the work. EPA also notes on its irrigation controller page that some utilities offer rebates; learn yours, since a rebate can help a customer say yes to a smart controller retrofit.

How do 811 and insurance fit in?

811. Installs, trenching and many repairs mean digging. The 811 Before You Dig program of the Common Ground Alliance bills 811 as a free service and asks for notice a few business days before work starts. Utility marks have a limit that matters in this trade. Virginia 811 lists sprinkler systems, landscape lighting and invisible pet fences among the private lines its member utilities will not mark, since public marks generally stop at the meter. So the existing system you are adding a zone to will not be painted on the lawn. Ask for an as-built drawing, locate valves and lines by hand, and probe before you trench.

Insurance. General liability that covers damage to buried utilities and property water damage from a failed fitting, commercial auto for the truck and any trailer-mounted compressor or trencher, and equipment coverage. Before hiring, check your state's workers' compensation rules. Our contractor insurance guide explains certificates commercial clients will ask for.

What equipment does an irrigation company need?

• Service truck with organized bins of heads, nozzles, fittings, valves, wire connectors and pipe in the sizes used in your area.
• Air compressor sized for blowouts in freeze climates, usually towable or truck-mounted.
• Diagnostic tools: a multimeter, a wire and valve locator, a pressure gauge, and a controller you can use to test zones.
• Digging tools: sharp spades, a trenching shovel, and a probe; rent a trencher or vibratory plow for installs at first.
• Pipe tools: cutters, primer and cement for PVC, crimp and insert tools for poly pipe.
• Backflow test kit if you are certified to test.

Open an account with an irrigation supply house. Learn the controller and valve brands most common in your area, since repairs go faster when you know the parts on sight.

How should you price irrigation work?

• Seasonal visits (startup, midseason check, winterization): a flat price by zone count, with a base for the first few zones and a per-zone add-on.
• Annual plans: all seasonal visits bundled at a set price, billed once or in installments, with priority scheduling and a set rate on repair labor. Plan customers get booked first when the rush comes.
• Repairs: a service call fee that covers diagnosis and travel, plus parts and labor, or flat prices for common repairs (head replacement, valve rebuild).
• Installs: priced by zones, heads or drip footage, pipe length, controller, backflow assembly and permit, with design and water source conditions noted.

Each of these must clear the hourly floor explained in our pricing guide, and our recurring billing guide covers setting up plans on autopay.

How do you find irrigation customers?

• A website with online booking for startups and winterizations, with a zone count field and a choice of week. In spring and fall it takes requests around the clock without phone tag. See websites.
• A Google Business Profile listing repairs, startups and winterizations separately, with photos of real repairs. See our Business Profile guide.
• Repair calls answered fast. A line that will not shut off or a head shooting water into the street sends homeowners to search. The company that answers gets the first chance to earn that customer's startups and winterizations too.
• Lawn care and landscaping companies without irrigation crews, who see broken systems every week.
• New construction neighborhoods where builder-installed systems need adjustment and first-year service.
• HOAs and commercial properties with many controllers, once you have insurance certificates and capacity.

Marketplace leads arrive one request at a time, from wherever the customer lives, and you pay for each lead whether or not it fits your routes. Your own customer file, holding zone counts and controller models, is what fills a route. The irrigation industry page shows how we set up booking, phones and CRM for this trade.

Which systems keep an irrigation company organized?

• A system record per property: zone count and map, controller model, valve locations, backflow device type and test dates, photos, and the parts used last time. Our custom CRM stores this against each address.
• Route scheduling by neighborhood for startups and blowouts, with automatic text confirmations the day before.
• Backflow test reminders and report records, if testing is required where you work.
• A phone that answers during the rush, with a missed-call text and shutoff instructions for customers with a running line. See AI receptionist.

How seasonal is irrigation across the US?

• North, Midwest and Mountain West: two rushes a year. Spring startups bunch into a few weeks once freezing nights end, and winterizations must finish before the first hard freeze. Summer is repairs and installs. Winter is quiet, so many owners pair irrigation with snow removal or holiday lighting.
• South and Southeast: no blowout season in most areas, but systems run much of the year, so repairs, controller adjustments and freeze-protection checks during cold snaps keep work steady.
• Arid Southwest and California: water restrictions, watering-day schedules and rebate programs drive demand for smart controllers, drip conversions and audits. Learn your local water rules before customers ask.
