This capacity (23 mgd) is more than enough to meet the 2013 estimated peak day demand of <br />13 mgd for the Joint Utility. Peals day demand and available well capacity are shown in Figure 5.2 and <br />Table 5.1. Required firm well capacity versus available firm well capacity is shown in Figure 5.3 and <br />Table 5.1. <br />As shown in Figure 5.2, capacity in excess of peak day demand is a result of the requirement for each <br />individual city to maintain its own firm well capacity. In a combined utility, this excess capacity can be <br />harnessed to reduce the total number of wells needed to meet future demand. One of the most <br />immediate benefits of this excess firm capacity is that future capital investment could shift from drilling <br />wells to interconnecting the communities with adequately sized trunk watermain. If the water distribution <br />systems are properly interconnected to allow enough water to flow between the cities, no new wells <br />would need to be drilled in the six -city Joint Utility until 2021 or later if demand trends continue to <br />decline. <br />Joint Water Utility Feasibility Study 16 <br />
