Irrigation design for Orange County landscapes

Drip irrigation on dedicated zones for each hydrozone (planting type and water need), inline emitters for groundcover beds, point-source emitters for shrubs and trees, no overhead spray on planting (turf only, where lawn remains), a weather-based ET controller, a master valve, a flow sensor, and a pressure-regulating filter at the point of connection.

A hydrozone is a group of plants with similar water needs irrigated together, so each zone gets only as much water as its plants actually need instead of one controller running every zone the same. Hydrozoning is also commonly expected by California water-efficiency requirements.

Yes, when designed and installed properly — pressure-regulated, filtered, and zoned correctly. The failure modes are clogged emitters and rodent damage, both of which a contractor can address at the annual checkup.

Yes. A weather-based controller adjusts run time based on local ET data, so the system waters less in May and more in August automatically. They are also commonly required for larger new or renovated landscapes, depending on your jurisdiction.

Point of connection, mainline routing, valve locations with zone numbers, lateral routing by zone, emitter or head specifications by zone, controller location, and a hydrozone schedule. We do not prepare water-district compliance worksheets or submittal packages.
