Irrigation System Installation
Irrigation system installation transforms dry pastures, lawns, and crops into productive, healthy landscapes—delivering consistent water where rainfall falls short. Tacoma Creek Build Co. designs and installs agricultural and residential irrigation systems across Spokane County, Pend Oreille County, Kootenai County, and Bonner County, handling everything from water source connections to zone controllers, mainlines, laterals, and sprinkler heads. Whether you're establishing a new lawn in Sandpoint, restoring pasture grazing capacity near Newport, irrigating a vineyard near Coeur d'Alene, or managing hay fields in Spokane County, we deliver efficient irrigation solutions that conserve water, reduce labor, and pass inspection.
Inland Northwest irrigation faces unique challenges: water rights must be secured for surface water, wells require adequate capacity and pressure, and seasonal freeze-thaw cycles demand proper winterization. We've installed drip systems, overhead sprinklers, center pivots, and hand-line setups across diverse terrain and crops—always matching system type to water availability, soil conditions, and management goals. When you need comprehensive site utilities, we coordinate land clearing, trenching, water lines, power, and irrigation as a complete package.

Our Process
Step 1: Water Source Identification – We identify available water sources: domestic well (requires separate irrigation tap or booster pump), dedicated irrigation well, municipal connection, pond, or surface water (creek, canal). Water rights are verified for surface water sources—we coordinate with water masters or irrigation districts as needed. Flow rate (GPM) and pressure (PSI) are measured or calculated to determine system capacity.
Step 2: System Design & Layout – We layout irrigation zones based on area, plant types (turf, pasture, crops, landscaping), sun exposure, and slope. Each zone is sized to match available flow and pressure. Sprinkler types (rotors, sprays, impact heads, drip emitters) are selected per application. Mainline and lateral pipe sizes are calculated to minimize friction loss and ensure adequate pressure at all heads. Controllers, valves, and backflow preventers are specified per code and water district requirements.
Step 3: Permitting & Backflow Testing – Backflow prevention devices are required to prevent irrigation water from contaminating domestic water supplies. We install approved backflow assemblies (pressure vacuum breaker, reduced pressure zone, or atmospheric vacuum breaker) and coordinate annual testing with certified testers. For municipal connections, we obtain permits and coordinate meter installations with water districts.
Step 4: Mainline & Lateral Installation – Mainlines (primary supply lines from source to zones) are trenched 18-24 inches deep to prevent freeze damage and equipment strikes. Laterals (zone distribution lines) are trenched 6-12 inches deep for residential systems, or surface-laid for agricultural hand-lines. PVC or poly pipe is installed with proper fittings, glued or clamped per manufacturer specs. Valve boxes are set at zone valves for access and winterization.
Step 5: Head Installation, Testing & Startup – Sprinkler heads, drip emitters, or impact sprinklers are installed per design spacing and adjusted for coverage. The system is pressurized to check for leaks at fittings, heads, and valves. Flow rates and pressure are verified at each zone. Controllers are programmed with run times, days, and seasonal adjustments. We train owners on controller operation, manual overrides, and winterization procedures (blowing out lines before freeze).
