Indoor water <br />use was calculated using an estimate of 85 gallons per day per person and 2.9 people per <br />dwelling unit. This translates to approximately 250 gallons per day per tap equivalent. Irrigation <br />use was estimated based on a use of 3 feet per year per acre and an average irrigated lot size of <br />3,300 square feet for a single family unit. The irrigation use per tap equivalent averaged over the <br />entire year is approximately 200 gallons per day. (WWE 2002) <br /> <br />2.1.5 Seasonality of W ater Use <br /> <br />Most of the irrigation water use occurs during the summer months when the temperatures are <br />high and the amount of precipitation is limited. The irrigation season in Colorado is generally <br />from May to October. Because of the increase in irrigation, the majority of water use occurs in <br />the summer months. During the winter months, water demand mainly consists of indoor water <br />use. <br /> <br />2.1.6 Trends in Water Use <br /> <br />The current trends in water use in the ACWW A service area can be linl(ed with the development <br />of the area. As the service area has become more developed, the need for water has increased. <br />Water use trends are predicted to increase consistently in the coming years because the ratio of <br />residential use to commercial use in the service area is not predicted to change. <br /> <br />November 2006 <br /> <br />15 <br /> <br />Richard P.
