Historically,water usage predictionswere established usingpopulation growth projections.For <br />example, if the City were to double its population, it was thought reasonable to assume that <br />water usage would also double. This approach does not take into account the mix of <br />Commercial and Industrial customers, which are historically high water users. <br />Table 2b – Potable Water Use byCustomer Type from 1995 to 2006 <br />YearResidentialCargillCommercial,Total PotableAnnual % <br />Outside City(MG)Change <br />(MG)(MG)& Irrig.

Reliable <br />historical data exist only at the influent meter measurements at theWater Treatment Plant, <br />reduced by a 1% treatment plant loss and a 6% distribution system loss to arrive at the total <br />potable delivers shown. An analysis of water use for a water rate study prepared in 2000 was <br />used to determine proportions of potable water delivered to residential, commercial and <br />irrigation customers and to Cargill Meat Solutions. <br />Residentialusers have historically accounted for about 42% of total potable water deliveries, the <br />largest users next to Cargill Meat Solutions.Total potable water demands rose 19% from 1995 <br />to 2000, the peak year, with a sharp decline in 2003 primarily due to drought restrictions and a <br />shifting of some of Cargill Meat Solutions’ demands to non-potable groundwater supplies. A <br />sharp increase in water usage was also noted from 1999 to 2000 when the City switched its <br />water supplies from groundwater to C-BT. Average annual growth in potable water demands <br />2 <br />from 1995 through 2006 was 0.485%, roughly a third of the population growth. <br />2 <br /> Water Supplies and Demands for Participants in the Northern Integrated Supply Project, Harvey Economics, March <br />30, 2006, Appendix H, Page H2. <br />City of Fort Morgan Water Conservation PlanPage 15 <br />
