Irrigation system water usage

Our water bill is still very high.  For example, the most recent one was for 23,000 gallons, double the previous month, and 10X our normal winter usage.

So the question is, what is our current irrigation system water usage? We have asked this before, in July 2014, and October 2017.


  We ran each zone by hand, for the same time as what the schedule says, and our results are:

Zone	Gallons	Time
Zone 1	15	30	drip
Zone 2	100	30	drip
Zone 3	194	30	drip
Zone 4	624	30
Zone 5	32	30	drip
Zone 6	642	30
Zone 7	278	20
Zone 8	673	30
Zone 9	360	20
Zone 10		off
Zone 11		off
Total	2918

So figure about 3000 gallons per usage. And that will go up when we add back in Zone 10 and Zone 11 once we finish the front yard excavations.
