Here is the link to information on the dates and times that Villagers are allowed to water their lawns:

I cannot believe your lawn service advised you to water 3 days a week unless your lawn is new, since that is not allowed anywhere in the Villages.
The tuna can suggestion was good, I cannot believe you need to water for 90 minutes in the same zone.
Also be aware that although we really didn't have any freezes this year, you want to shut off your system if freezing temps are expected.
