What are irrigation zones, and what role do they play in landscape irrigation design?
Irrigation zones are used to focus water usage on specific parts of your yard at specific times in the watering cycle. Using hydraulics, Christianson determines the amount of heads that will be needed to efficiently cover a single zone. Spray heads and rotary heads will be on separate zones. Some zones are designated for turf, and others for landscape beds. The control valve at each zone receives a signal from the controller. The valve opens and allows the water to enter the zone and water the specified area.
