Certified Irrigation Installation in Washington, DC Since 1981
Washington, DC’s Plumbing Code sets explicit requirements for outdoor irrigation systems: designs must reduce potable water use by 50 percent, and installation must be supervised by a certified or accredited irrigation professional. Contractors operating in the District need to address those standards. Chesapeake Irrigation & Lighting does. We’ve been installing irrigation systems across the Baltimore and DC region since 1981, and our team holds EPA WaterSense Partner status alongside Rain Bird Select Contractor standing, two credentials that relate directly to DC code compliance.
We serve both residential and commercial clients throughout Washington, DC, and every project starts with a free, upfront estimate.
Why Washington, DC Clients Choose Chesapeake Irrigation & Lighting
Our credentials aren’t the only reason DC property owners work with us. The way we operate sets us apart in this market.

Irrigation Installation Services in Washington, DC
Every irrigation installation we complete is custom-engineered to the property. DC code requires zone mapping based on plant water needs, controllers that respond to weather, climate, or soil moisture data, and rain-sensor capability that suspends irrigation during rainfall. These aren’t optional features; they’re compliance requirements we build into every system from the design stage.
Residential properties in the District present specific challenges: compact lots, dense urban soils, and hard surfaces all affect head placement, zone layout, and runoff management in ways that suburban installations don’t encounter. Commercial properties, including office campuses, multi-family buildings, and hospitality sites, require large-scale zone management under the same DC water-efficiency standards. Our team’s 200-plus years of cumulative experience covers both.
Beyond installation, we handle the full irrigation service lifecycle. Spring turn-on, system repair, and winterization are all performed by the same in-house crew that installed your system. We use green products throughout and approach every project as the start of a long-term relationship, not a one-time job.

How Irrigation Installation Works: From Site Assessment to System Handoff
A properly installed irrigation system begins well before any trenching starts. Here’s what happens at each stage and why it matters for DC properties.
Site Assessment
The process opens with a thorough evaluation of the property: measuring the site, mapping planting zones, assessing soil type and sun exposure, and measuring water pressure and flow rate at the point of connection. These readings determine what the system can support and how it should be sized.
Zone Design
Zone mapping groups areas of the property by plant water needs. Under DC Plumbing Code, this isn’t an aesthetic choice; it’s a technical requirement. Getting zone boundaries right at the design stage is also a key driver of long-term system efficiency.
Component Selection
Sprinkler head type and placement, pipe routing, valve manifold location, and controller selection are all determined during this phase. DC code requires that irrigation controllers regulate watering based on weather, climate, or soil moisture data, so selecting the right unit means matching it to the property’s zone count and connectivity needs.
Installation
Installation covers trenching, pipe laying, head installation, valve and manifold assembly, and controller wiring. Backflow preventer connection is handled by a licensed plumber, as DC jurisdiction requires annual testing of backflow devices on systems connected to the public water supply.
Controller Programming & Client Walkthrough
Once installation is complete, we program the controller, run each zone to verify coverage and head performance, and walk you through system operation, zone schedules, and manual controls. You leave the project knowing exactly how your system works.
The quality of the initial installation determines how the system performs across every season that follows. Misaligned heads, undersized pipe, or incorrect zone grouping don’t stay minor problems; they compound into costly corrections over time. Getting the installation right supports long-term maintenance.
In the Washington, DC region, winterization is a required annual step. Freeze-thaw cycles can rupture underground lines and damage valve assemblies if residual water isn’t cleared with a compressed-air blowout before temperatures drop. Annual spring startup involves pressure checks, head adjustments, controller reprogramming for seasonal schedules, and backflow device inspection to meet DC’s annual testing requirement.
Because Chesapeake Irrigation & Lighting handles installation and ongoing seasonal services with the same in-house crew, the technicians who service your system each spring and fall already know how it was built. That continuity is one reason thousands of clients across the region have relied on us season after season.
From consultation and design through professional installation and ongoing maintenance, our in-house team delivers a seamless customer experience.
