DRAFT 8 -17 -07 <br />Table No. 4 <br />Water Demand Projections <br />Year <br />Total <br />Community <br />Population <br />Population <br />Served By <br />Water System <br />Average Day <br />Demand (MGD) <br />Maximum Day <br />Demand (MGD) <br />Projected <br />Annual <br />Demand (MGY) <br />2010 <br />21,500 <br />17,514 <br />1.73 <br />4.76 <br />632.9 <br />2020 <br />26,500 <br />23,000 <br />2.28 <br />5.93 <br />832.2 <br />2030 <br />31,000 <br />29,000 <br />2.87 <br />7.46 <br />1047.6 <br />Ultimate <br />43,000 <br />42,000 <br />4.16 <br />10.82 <br />1518.4 <br />Based upon the estimated ultimate population to be served by the City water system and <br />the water treatment plant requirements, we recommend that the City use the blending <br />process to meet the estimated ultimate maximum day water demand of 10.4 -10.8 MG. The <br />water treatment plant with a 1.5 or 2.0 MG finished water reservoir should be designed to <br />process 8.4 MGD through the treatment plant and to allow bypass of 2.1 MGD direct to the <br />finished water reservoir. A water treatment plant designed and constructed to provide 8.4 <br />MGD of finished water will likely provide fully treated finished water for all of the City of <br />Lino Lakes needs through the year 2040. The blending process should allow the City to <br />meet the ultimate peak day water demands. <br />Water Treatment Plant Study 11 13843.000 <br />
