Add Heads and
Adjust Spacing
• Add sprinklers along
the sides or center to
increase coverage.
A watering zone or station consists of a group of sprinklers attached to one valve.
The number of heads per zone will be determined in this section.
Purpose of Zones
Zones are designed to:
• Maintain adequate water flow for optimal spray coverage (Avoid dry patches)
• Separate areas based on watering requirements
- Shade vs. Full Sun Areas
- Lawn vs. Shrubs
Important:
• Do not mix sprinkler types in the same zone (e.g. Gear Drive, Impacts, Pop-Ups and Bubblers)
• Do not exceed the maximum sprinkler heads recommended per zone
• Use the recommended pipe size in this guide. Smaller diameter pipe will decrease the water flow.
Group Heads of Same Type in the Same Area
Starting with large area heads, use the following
example as a guide.
• Identify all large area heads on
your drawing.
