The rule is that you are supposed to water no more than two times per week, and only at times after dusk and before dawn. If you water for less than about 10 minutes per zone, it will probably be sufficient, but it may need to be adjusted as needed. You can monitor the amount of irrigation water used per month on your water bill. The amount of irrigation water used should be between about 2,000 and 5,000 gallons per month, depending on the size of your lawn. These are just estimates, based on my experience. I think a lot of people tend to overwater their lawn.

By the way, water bills are public information. So, you can view your neighbor's water bill by entering their address onto the utility website and compare their water usage to your usage.
