Irrigation & Sprinkler Systems in Woodinville, WA

Yes, designed to what the well can actually deliver rather than to municipal assumptions. That means establishing two numbers first: flow, which sets the maximum size of any single zone, and recovery rate, which sets how many zones can run in a day and how much rest is needed between them. The resulting design typically has more, smaller zones running over a longer window, often overnight, with gaps built into the schedule. Drip on planted areas helps significantly, delivering the same result at a fraction of the flow.

Almost never, and on a well it is frequently not even possible. On acreage the productive approach is a defined garden area near the house irrigated properly, with the wider property managed as meadow, woodland or paddock that needs no watering at all. That matches how the land is actually used, keeps the system within what the supply can sustain, and costs a fraction of attempting the whole thing. It also produces a better-looking property, because a well-watered garden with managed land beyond it reads as deliberate.

Across a septic drainfield, which is the constraint that shapes most Woodinville layouts. A drainfield needs the ground above and around it undisturbed and uncompacted, so trenching through it is not an option, and adding irrigation water to that area is actively harmful — a drainfield in saturated ground stops dispersing properly. On a large lot the field is frequently in the flattest, most convenient place to run a line. Locating the tank and field from records, or by survey where records are poor, comes before the design rather than during the trenching.

Considerably, and a property spanning both should be zoned across the difference. The Sammamish Valley floor is alluvial with a water table close to the surface, so planting there reaches moisture that ground on Hollywood Hill simply cannot. Running both on one schedule means over-watering below and stressing above. Where a whole garden sits on the valley floor, the system needed is usually smaller and cheaper than the same garden would require on the hill — which is a rare case of the difficult ground being the cheaper one.
