Local Water Supply Plan—Centerville <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 demand; <br /> 3) average daily demand;4) maximum daily demand. Then explain the causes for upward or downward <br /> trends. For example, over the ten years has the average daily demand trended up or down?Why is this <br /> occurring? <br /> Population growth in Centerville was less than 4% between 2005 — 2015 (3,848 to 4,005) per State <br /> records. Centerville has also decreased the number of households still on private well supply by <br /> extending water services to new areas. <br /> Centerville has historically had low per capita water demands and all trends are decreasing. Total per <br /> capita water demand is decreasing; from approximately 90 gpcd in 2005 — 2011 to 70 gpcd in 2014 — <br /> 2015.The total per capita water demand average was approximately 83 gpcd between 2010 and 2015. <br /> Average day water demand has remained nearly constant over the last 10 years as per capita water <br /> usage has dropped while population has increased. The maximum day water demands have varied <br /> depending on the summer weather's effect on lawn irrigation. Per capita water usage is trending down <br /> due to replacement of appliances and fixtures in existing homes and more efficient new homes. <br /> Use the water use trend information discussed above to complete Table 7 with projected annual <br /> demand for the next ten years. Communities in the seven-county Twin Cities metropolitan area must <br /> also include projections for 2030 and 2040 as part of their local comprehensive planning. <br /> Projected demand should be consistent with trends evident in the historical data in Table 2, as discussed <br /> above. Projected demand should also reflect state demographer population projections and/or other <br /> planning projections. <br /> Table 7.Projected annual water demand <br /> �IMflilll, <br /> 2016 3,802 3,605 100 0.36 1.08 <br /> 2017 3,806 3,627 100 0.36 1.09 <br /> 2018 3,811 3,648 100 0.36 1.09 <br /> 2019 3,816 3,670 100 0.37 1.10 <br /> 2020 3,840 3,692 100 0.37 1.11 <br /> 2021 3,849 3,713 100 0.37 1.11 <br /> 2022 3,858 3,735 100 0.37 1.12 <br /> 2023 3,867 3,757 100 0.38 1.13 <br /> 2024 3,876 3,778 100 0.38 1.13 <br /> 2025 3,885 3,800 100 0.38 1.14 <br /> 2030 3,930 3,822 100 0.38 1.15 <br /> 2040 4,060 4,060 100 0.41 1.22 <br /> GPCD—Gallons per Capita per Day MGD—Million Gallons per Day <br /> 8 <br /> 53 <br />
