FBC sprinkler performance

 

Aug 13 observations:

Zone 1 youth west.  Adjust 2 heads, leave on

Zone 2 west entry. Adjust 2 heads leave on

Zone 3 NW island. Adjust 4 heads leave off

Zone 4 north islands adjusted pretty well. Off for conservation

Zone 5 failed, off permanently

 

Zone 6 north property line, west part.  Guider by tree. Off.

Zone 7 west property leave off

Zone 8 west property leave off

Zone 9  south property leave off

Zone 10

9

 

 

 

Flow rate observation:

This looks like 20 gpm on one zone, and 25 gpm on two others.

 

I hope this math is wrong in some way:

each zone
consumes
25 gpm
x 12 zones x 20 min
per zone
x 2 application
per week
x 4.2 weeks
per month
x 0.03 cents
per gallon
Total water usage
each month
25 12 20 2 4.2 $0.03 = $1,512.00
