Creating zones is vital to successful sprinkler system design. Zones have a group of sprinkler heads connected to one sprinkler system valve. You must determine how many zones you need to have an effective lawn watering system. There are many reasons to create stations or zones. First, stations allow you to provide your yard with adequate coverage so there are no dry patches in your lawn. Second, watering zones help determine your yard's different watering needs such as shady versus sunny areas, grass versus shrubs, etc. Here are a couple of things to remember as you create your different sprinkler zones:
- Do not mix different types of water sprinklers in one zone (i.e gear drive, impact, bubbler, etc)
- Use a consistent pipe size throughout to maintain proper water flow
Once your large area sprinklers are complete, follow the above guidelines for creating stations with medium and small area yard sprinklers.
Be sure to apply a number to each zone so you know how many stations you have in your yard. This will later help you determine what kind of watering timer to use.
Now that you have split your yard into sprinkler zones, you can plan your sprinkler valve placement.
