Water sources vary from ground and surface water, and can be supplied by the City or from private wells for drinking, cleaning, sanitation, irrigation and more. In the Twin Cities metro area, approximately 20 percent of all treated drinking water is used outdoors, with a majority of this being used on lawns and landscapes. According to a University of Minnesota Extension and Metropolitan Council study, water use in the summer months is nearly three times greater than water use in the winter.
