Setup for Overlapping Zones

[franz]

@nunny1969

For example, my front yard has 3 zones that overlap each other. Zones 1 and 2 significantly overlap each other (for sake of argument, let’s say they overlap by 50%). As well, zones 2 and 3 overlap each other to the same extent as 1 & 2. (i.e. zone 2 is “filling in the gaps” of zones 1 and 3).

With this scenario, if I enter full square footage for the sprinkler head coverage of all 3 zones, won’t Iro miscalculate the amount of water needed for zone 2 (too much water)?

There are a few concepts here. In this context the measurements that affect watering duration are the nozzle precip in/hr rate and nozzle efficiency (distribution uniformity). You can use our default nozzles or by using a catch cup test create your own custom nozzle.

Water usage seems very high

If you do want to measure actual nozzle output, this should help. You will need catch cups: No clue what the delivery is on these… http://irrigation.tamu.edu/coursematerials/Utah%20Irrigation%20Catch%20Cup%20Order%20Form.pdf Next day delivery… This explains how to set the catch cups… http://wateringschedule.com/wp-content/uploads/2013/04/26250-24-rB21.pdf Once you are finished, this handy calculator will give you the exact in/hr precipitation rate as well as the nozzle efficienc…

Zone square footage only affects the estimated gallons used/saved we display and does not affect the watering duration.

Hope this helps.
