For years we used a shared well and were always concerned about our water use, sharing in the pumping costs. We used drip irrigation for our plants and trees in the yard. The shared pump finally gave out about the time the neighborhood came to an agreement with NID to provide treated water for our homes and yards. That water was metered, and we could gage the amount we were using, becoming even more aware of our water use at home.
At our house the master bath is a long way from our on demand water heater in the pantry. I was using a lot of water just waiting for some hot shaving water. I solved the problem by buying a small electric tea kettle, and used the hot water it create for shaving and washing up when required. This reduced our water use by gallons per week. You might try this option as you seek to comply with the Governor’s conservation measure, that is if your sinks are a long way from the water heater.
