Professional Irrigation & Sprinkler Systems on Long Island

A properly designed and installed irrigation system delivers water precisely where and when your lawn and gardens need it — reducing water waste, preventing over-watering that promotes disease, and ensuring consistent coverage that hand-watering cannot achieve. We design zone-by-zone based on sun exposure, plant types, soil drainage, and slope — never a one-size-fits-all approach. Every system includes a smart controller that adjusts watering based on weather conditions, and rain sensors that shut off the system automatically.

Irrigation & Sprinkler Systems on Long Island — What You Need to Know

Long Island's summer drought periods — often June through August — make irrigation nearly essential for maintaining a healthy lawn without hand-watering. Water restrictions are increasingly common in Nassau and Suffolk counties during drought declarations, making efficient irrigation design critical. Sandy south shore soils require more frequent, shorter watering cycles (the soil can't absorb water faster than it drains), while north shore clay soils need slower, deeper watering with more time between cycles. We size zones and heads accordingly.

Best time for this service: Start-up April–May; Winterization October–November

Frequently Asked Questions — Irrigation & Sprinkler Systems

When should I winterize my sprinkler system on Long Island?

Winterization should be completed before the first hard freeze — typically between mid-October and mid-November on Long Island. We use compressed air blow-out method to evacuate all water from lines and heads, preventing costly freeze damage. Don't wait until the last minute — our schedule fills quickly in October.

Do Long Island towns have water restrictions that affect irrigation?

Yes. Nassau and Suffolk counties, along with many individual incorporated villages, can and do issue water use restrictions during drought conditions — typically odd/even day watering rules or total bans. Smart controllers with soil sensors or ET-based scheduling help you maximize lawn health within these restrictions.

How long should I run my sprinklers on Long Island?

Most Long Island lawns need approximately 1 to 1.5 inches of water per week in summer. Run times vary by head type: rotor heads typically need 30–45 minutes per zone to deliver that amount, while fixed spray heads need 10–20 minutes. Sandy south shore soils benefit from two shorter cycles rather than one long one to prevent runoff.

Is a sprinkler permit required in Nassau or Suffolk County?

Most municipalities in Nassau and Suffolk County require a permit for new irrigation system installation, and all systems must include a certified backflow prevention device tested annually. We handle all permits and inspections as part of every new installation.
