TL;DR
An irrigation zone is a group of sprinkler heads or drip emitters piped to one control valve and watered as a unit, sized so the system's available flow and pressure can supply every head in the group at once. Designers split yards into these sections by plant type, sun exposure, and head type, since turf rotors and shrub drip need very different run times.
What it means
An irrigation zone is a group of sprinkler heads or drip emitters piped to one control valve and watered as a unit, sized so the system's available flow and pressure can supply every head in the group at once. Designers split yards into these sections by plant type, sun exposure, and head type, since turf rotors and shrub drip need very different run times. Each one appears as a numbered station on the controller, which is how homeowners adjust schedules, and a zone that stays wet or dry usually traces to its valve or wiring.
