Water Use and Demand Forecast <br />Over the past 15 years, population growth in Alamosa has been running well below state <br />averages at approximately 0.8% per year. <br />Using the assumption that <br />Alamosa's population growth <br />rate will increase no more than <br />1.5% per year, Alamosa's <br />population growth rate will <br />remain well below state <br />historic averages. <br />Water production has been <br />increasing at 1.05 percent per <br />year — a rate slightly above that <br />of the City's population <br />growth. <br />Alam osa Population* <br />12,000 <br />10,000 <br />8,000 <br />— 6,000 <br />4,000 <br />2,000 <br />0 <br />O O N M C= OO O7 O <br />C=0 O O O O O O O O O O N N <br />G7 O O O O O O O O O O O O O O <br />Year <br />* See Appendix A for supporting data tables <br />In order to sustain the use of our limited water supplies, we need to do two critical things: <br />• Increase efficiency; <br />• Decrease demand. <br />First, we must increase the <br />efficiency the water we use to <br />ensure we get the most out it. <br />An example of efficient use is <br />finding ways to reduce the <br />amount of water needed to <br />irrigate five acres of bluegrass. <br />Second, we must reduce our <br />overall water by identifying <br />current uses that can be <br />reduced or eliminated.

Both approaches will be addressed in this plan. <br />City of Alamosa I Water Conservation Plan I May 2007 1 Page 7 of 29 <br />ti��h ti��h <br />
