Local Water Supply Plan Template –July 8, 2016 <br /> <br />14 <br /> <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.

An average total per capita <br />demand was determined from the City’s historic water usage data and was assumed to remain constant at 123 <br />gallons per capita per day through 2040. Since the City is unable to record the amount of water pumped on individual <br />days, trends were in maximum day demands were not available. Therefore, a maximum day peaking factor of 3.0 <br />was assumed to calculate the City’s projected maximum day water demands. <br /> <br />E. Resource Sustainability <br />Monitoring – Key DNR Benchmark <br />Complete Table 8 by inserting information about source water quality and quantity monitoring efforts. <br />List should include all production wells, observation wells, and source water intakes or reservoirs.
