We have a corner lot, water three times a week for the lawn, approx 1 hour per zone. We have a lot of palms, plants and shrubs and also water them three times a week (not the same days) for 20 minutes per zone. All watering times and frequency are determined by our lawn care company....which is why they were hired. My wife is very happy
. Average usage this summer was about 30,000 gal/mo.
