This <br />peaking factor was assumed for the year 2017 and then <br />decreased linearly to reach the goal of 2�6 by the year 2030� A <br />peaking factor of 2�6 was applied from 2030 to 2040� <br />Table 9-4 Water Demand Projections <br />Year Projected Total <br />Population <br />Projected <br />Population <br />Served <br />Projected Total <br />Per Capita Water <br />Demand (GPCD) <br />Projected <br />Average Daily <br />Demand (MGD) <br />Peaking Factor <br />Projected <br />Maximum Daily <br />Demand (MGD) <br />2017 15,729 12,493 93 1�16 3�43 3�99 <br />2018 16,853 13,542 93 1�26 3�37 4�24 <br />2019 17,976 14,591 93 1�36 3�30 4�48 <br />2020 19,100 15,640 93 1�45 3�24 4�71 <br />2021 20,090 16,666 93 1�55 3�17 4�92 <br />2022 21,080 17,692 93 1�65 3�11 5�12 <br />2023 22,070 18,718 93 1�74 3�05 5�30 <br />2024 23,060 19,744 93 1�84 2�98 5�48 <br />2025 24,050 20,770 93 1�93 2�92 5�64 <br />2030 29,000 25,900 93 2�41 2�60 6�26 <br />2040 40,000 37,000 93 3�44 2�60 8�95 <br />GPCD – Gallons per Capita per day MGD – Million Gallons per Day
