What Is the Irrigation System Installation Cost in 2025?
Updated May 1, 2026
A clear, up-to-date breakdown of what a new sprinkler or drip irrigation system costs in Orange County in 2025 — and the factors that move the price.
AI-generated audio summary. For the full detail, read on.
What does a new irrigation system cost?
For most Orange County homes, a professionally installed irrigation system runs in the low-to-mid four figures, with the final number driven by the size of the area, the number of zones, the system type, and how much trenching is involved. Smaller front-yard systems sit at the lower end; large properties with many zones and mixed planting sit higher.
What you are actually paying for
The price covers more than sprinkler heads. It includes design and zoning, the controller, valves and manifolds, backflow prevention, piping, trenching and backfill, the heads or drip emitters themselves, and labor. A well-designed system distributes water evenly and avoids the dry spots and runoff that waste money month after month.
Spray and rotor vs. drip
Traditional spray and rotor systems are ideal for lawns and large open areas. Drip irrigation — which delivers water slowly right at the root zone — is more efficient for planting beds, shrubs, and drought-tolerant designs, and usually costs less to run. Many Orange County properties use a mix of both, zoned separately so each plant type gets exactly what it needs.
The biggest cost factors
Three things move the price most: the number of zones (more zones = more valves, wiring, and labor), trenching (rocky soil or crossing hardscape adds time), and whether you are starting fresh or retrofitting an existing system. Add-ons like a smart, weather-based controller cost a little upfront but typically pay for themselves through lower water bills.
Is it worth it?
An efficient system protects your landscape investment and can meaningfully cut water use compared with hand-watering or an old, poorly zoned setup. In a climate like ours, that adds up quickly.

Frequently asked questions
How much does a sprinkler or irrigation system cost?
For most Orange County homes a professionally installed system runs in the low-to-mid four figures. The biggest variables are the number of zones, the area covered, the system type (spray, rotor, or drip), and how much trenching the site needs. We provide a free, itemized estimate so the number is specific to your property.
Is drip irrigation cheaper than sprinklers?
Drip usually costs less to run because it delivers water straight to the roots with little waste, making it ideal for planting beds and drought-tolerant designs. Upfront cost is comparable; most OC yards use a mix — spray or rotors for lawn, drip for beds — zoned separately.
Do smart irrigation controllers actually save money?
Yes. A WaterSense-labeled, weather-based controller adjusts watering to the season automatically and can cut irrigation water use by about 30% — the EPA estimates roughly 15,000 gallons saved per home per year, so it typically pays for itself.
Should I repair my old system or replace it?
If the layout is sound, repairs and a tune-up (heads, valves, a new controller) are the cost-effective fix. If zoning is poor, coverage is uneven, or the system is badly aged, a redesign often saves more water and money over time. We will assess and give you both options.
How long does an irrigation installation take?
A typical residential system is installed in a few days depending on the number of zones, trenching, and site access. We give you a clear schedule once the design and estimate are approved.
