4. Unaccounted water will represent 1 % of the total water use. This value is well within the range of acceptable unaccounted water use values according to the American Water Works Association. This is equivalent to 1 gpcd. 5. Total gross water use is projected to be 150 gpcd. 6. Peaking day water usage is calculated using a peaking factor, which is a ratio of the expected peak day flow over average day flow. Recent history indicates that the peak day to average day ratio has been decreasing over the past 9 years. A peaking factor of 3.0 would typically be utilized for long-term projections of a system of the size of Ramsey's. This peaking factor is representative of the ratio over the past 4 years, and will be utilized for future projections. Figure 2.2 provides a summary of the projected average and maximum day water usage for the planning period. Appendix A has a detailed breakdown of projected population and water demand for the study period.
