Feasibility Study <br />Water Treatment Plant <br />City of Lino Lakes, MN <br />WSB Project No. 015822-000 Page 13 <br />4. WATER DEMANDS <br />4.1 Historical Water Use <br />The City of Lino Lakes historical water demands for the last ten years are summarized in Table 4- <br />1 below. <br />Table 4-1.

The <br />demand within a given year is sensitive to the climate behavior in that year. Therefore, even <br />though total per capita water demand has been less in recent years, the average total per capita <br />water demand from 2010 to 2019 of 86 gallons per capita per day was used for the projections in <br />this report in order to be conservative for planning purposes. <br />4.3 Future Water Demand Projections <br />The City of Lino Lakes’ water demand projections are summarized in Table 4-2 below. The <br />projected population growth is based on the City’s Draft 2040 Comprehensive Plan Update. The <br />total per capita water demand is the average demand from 2010 to 2019. The maximum day <br />peaking factor is the average peaking factor from 2010 to 2019, except for the ultimate projection <br />which uses the DNR’s recommended target of 2.6. The City’s peaking factor has shown a <br />decreasing trend in the last ten years, and the City could possibly meet the DNR’s target before <br />reaching ultimate development with additional conservation efforts and education. <br />Table 4-2.
