Ronkonkoma, NY
McCormack Irrigation serves Ronkonkoma, NY with lawn sprinkler installation, spring turn on, winterizing, sprinkler repair, backflow testing, landscape lighting, drip irrigation, commercial irrigation, and commercial snow removal. Ronkonkoma spans the Town of Islip and the Town of Brookhaven at the geographic center of Suffolk County, and our crews have worked its residential streets and industrial parks since 2001.
Few Long Island hamlets combine as much residential and commercial ground as Ronkonkoma. On one side are the neighborhoods around Lake Ronkonkoma, Long Island’s largest freshwater lake. On the other are the Long Island Rail Road terminal, Long Island MacArthur Airport, and the warehouses and office parks that surround Veterans Memorial Highway and the Long Island Expressway. We handle irrigation for the first and both irrigation and seasonal snow removal for the second.
We are family owned and operated, and every job is done by our trained, uniformed, in-house staff. We do not use subcontractors for irrigation, lighting, or snow work.
Our Services in Ronkonkoma
- Lawn Sprinkler Installation: Zoned systems for Ronkonkoma’s flat, sandy lots, with head spacing and run times that keep water in the root zone instead of draining through.
- Spring Turn On Service: Careful pressurization, full inspection, and controller programming to match SCWA watering rules.
- Winterizing Service: Compressed-air blowout and draining of heads, piping, fittings, solenoid valves, manifolds, exposed plumbing, and hose bibs before the first hard freeze.
- Sprinkler Repair Service: Repairs on any brand, from single heads to full valve manifolds and controllers.
- Backflow Testing: Annual testing by New York State certified testers for homes and the many commercial facilities in Ronkonkoma that are required to have testable devices, with paperwork filed with the local water district.
- Landscape Lighting: Low voltage LED and color changing lighting for homes around the lake and for commercial entries and signage.
- Commercial Snow Removal: Seasonal plowing contracts for industrial parks, distribution facilities, shopping centers, and apartment complexes near MacArthur Airport and the LIE. Commercial only.
- Drip Irrigation: Efficient low-flow watering for planting beds, especially valuable on sandy soil where spray heads lose water to drainage and evaporation.
- Commercial Irrigation: Design, installation, and maintenance for office parks, warehouses, and multifamily properties.
From Lake Ronkonkoma to the Airport Industrial Parks
Ronkonkoma’s residential heart is the area around the lake. Suffolk County’s Lake Ronkonkoma Watershed Management Plan identifies it as the largest freshwater lake on Long Island, with shoreline shared by the Towns of Islip, Brookhaven, and Smithtown, and it flags stormwater runoff as a suspected source of the lake’s water quality problems. That matters for irrigation. Overwatering a lawn near the lake sends fertilizer and sediment downhill with the runoff, so we design systems in the lakeside neighborhoods to apply only what the turf can absorb, with rain sensors so the system stays off after a storm.
South and west of the lake, the character changes. Long Island MacArthur Airport, owned and operated by the Town of Islip, covers 1,311 acres with three runways, and the roads around it, Veterans Memorial Highway, Ocean Avenue, and the LIE service roads, are lined with distribution centers, manufacturing plants, and office parks. The Ronkonkoma LIRR station sits at the edge of this district. For these properties we provide two things: commercial irrigation for the lawns and plantings that keep a corporate frontage presentable, and commercial snow removal so loading docks, employee lots, and truck aprons are open after a storm.
The soil across all of Ronkonkoma is glacial outwash. The USDA’s Riverhead soil series, with its type location in the Town of Brookhaven, is well drained, formed in “glacial outwash deposits,” and has very high water movement through the substratum. Water applied to a Ronkonkoma lawn does not linger, so evenly spaced heads and correct run times matter more here than almost anywhere in Suffolk. Ronkonkoma is on the Suffolk County Water Authority distribution map, and SCWA’s odd/even watering schedule and 10 a.m. to 4 p.m. no-watering window apply. SCWA also requires commercial facilities to install approved, testable backflow prevention devices, which covers most of the airport-area properties we service. Many of those same facilities pair their annual backflow test with a commercial irrigation maintenance visit and a seasonal snow contract, so one crew handles the property year round.

Frequently Asked Questions
When should I winterize my irrigation system in Ronkonkoma?
Schedule your blowout in the fall before nighttime temperatures fall below freezing. Fall bookings fill quickly across central Suffolk, so do not wait until the last week of the season. Our winterizing timing guide has more detail.
What does winterizing include?
We blow out and drain the heads, piping, fittings, solenoid valves, manifolds, exposed plumbing, and hose bibs with compressed air, then shut down the controller.
Do you provide commercial snow removal near MacArthur Airport?
Yes. We plow and manage snow for industrial parks, warehouses, office buildings, shopping centers, and apartment complexes in the airport and LIE corridor under seasonal contracts. We do not plow residential driveways.
Can a snow contract cover loading docks and truck lanes, not just parking?
Yes. We scope each commercial contract to the property, including docks, drive aisles, employee lots, and walkways, so nothing is left to interpretation when a storm hits.
Why does my Ronkonkoma lawn need water so often?
The outwash soil here drains very quickly, so water moves past the roots fast. A properly designed system with the right head spacing and run times, plus a rain sensor, keeps the lawn healthy without waste.
Does overwatering near Lake Ronkonkoma cause problems?
It can. Runoff from overwatered lawns carries fertilizer and sediment toward the lake. We size and schedule lakeside systems so water soaks in rather than running off.
Is my Ronkonkoma business required to have a backflow device tested?
SCWA requires commercial facilities to install approved, testable backflow prevention devices. Our New York State certified testers handle the test and file the report with the water district. Read our backflow testing guide for details.
Do you install commercial irrigation for office parks and warehouses?
Yes. We design, install, and maintain commercial irrigation systems for corporate frontage, medians, and landscaped buffers throughout the Ronkonkoma industrial area.
Can you repair a system another company installed?
Yes. We service all major brands of residential and commercial irrigation systems in Ronkonkoma.
Do you use subcontractors for snow removal in Ronkonkoma?
No. All snow removal, like all of our irrigation and lighting work, is performed by our own trained, uniformed, in-house staff.
