If there are no limitations, list none. <br /> Well 2 is used to meet seasonal peak demands only. The City has two(2) interconnections with Anoka,one is hard <br /> piped and one uses hoses. <br /> D. Future Demand Projections -Key Metropolitan Council Benchmark <br /> Water Use Trends <br /> Use the data in Table 2 to describe trends in 1) population served; 2) total per capita water <br /> demand; 3) average daily demand; 4) maximum daily demand. Then explain the causes for <br /> upward or downward trends. For example, over the ten years has the average daily demand <br /> trended up or down? Why is this occurring? <br /> The following trends are observed: <br /> 1. Population served increased to a peak in 2010,then dipped in 2011 and increased again. See graph below. The <br /> overall upward trend is caused by new connections added each year and construction that occurred in the past 10 <br /> years. There have been about 60 connections added per year on average over the last 5 years. <br /> Population Served <br /> 14,000 <br /> 13,000 <br /> c 12,000 <br /> 0 <br /> 75 11,000 <br /> CL <br /> a° 10,000 <br /> 9,000 <br /> 8,000 <br /> 2004 2006 2008 2010 2012 2014 2016 <br /> Year <br /> 2.The total per capita water demand decreased from 166 GPCD in 2005 to 134 GPCD in 2015. Between 2005 and <br /> 2015, water use peaked at 189 GPCD and 184 GPCD in 2006 and 2007 respectively. Several measures may have <br /> contributed to the overall decrease in total per capita water use,including replacing all residential meters in a 5 year <br /> period, implementation and enforcement of a new topsoil ordinance, changing the rate structure and increased <br /> enforcement of irrigation restrictions. <br /> 15 <br />
