B. Future Sanitary Sewer Services <br /> <br /> 2001 Comprehensive Plan <br />Amended February 26, 2002 <br /> <br />Future facilities and flowage <br />Future sewer facilities are expected to serve new commercial, industrial and <br />residential development within existing and future areas of the Metropolitan Urban <br />Services Area (MUSA) boundary. The MUSA boundary is planned to be extended in <br />a westerly direction along Highway 10. Expansion of the MUSA will be done <br />consistent with the provisions and process outlined in the City Charter (see Appendix <br />H). The 1991 Comprehensive Sewer Plan illustrates how sewer pipes would be <br />extended to these areas. General locations and routes for potential trunk sanitary <br />sewer pipes are illustrated in Figure VIII-1. It is intended that individual <br />developments will tie into these trunk lines and that the trunk lines will be built in <br />accordance with the development staging plan as can be seen in Figure V-3. <br /> <br /> Future wastewater flowage will be primarily generated in the Mississippi River Sewer <br /> District as this is where the bulk of vacant land planned for urban development is <br /> located. Infill development will create some additional flowage within the Rum River <br /> Sewer District as well. The following tables project future wastewater flowage for <br /> each sewer district by land use category and development stage. These figures <br /> represent projections based on when sewer and water services are expected to be <br /> extended and correspond with the development staging plan. These figures do not <br /> indicate actual development numbers, however, they project wastewater flowage <br /> based on the proposed land use plan in order to adequately size the municipal sewer <br /> system. <br />Table VIII-4 Projected Wastewater Flows to the year 2020. <br /> <br />Mississippi River Sewer District Sewer Flows in Million Gallons Per Day (MGD) <br />Land Use Type 2000 Flows 2005 Flows 2010 Flows 2015 Flows 2020 Flows <br />Residential (Housing Units) 255 0.069 725 0.2009 1814 0.50854 2639 0.544 3684 0.826 <br />Commemial/Industrial/Institutional (acres 300 0.390 452 0.5861 550.6 0.70886 700.6 1.04 750.6 1.105 <br />Total Flows 0.459 0.787 1.2444 1.6891 2.0094 <br />Rum River Sewer District <br />Land Use Type 2000 Flows 2005 Flows 2010 Flows 2015 Flows 2020 Flows <br />Residential (Housing Units) 1400 0.378 2408 0.623 2913 0.7074 3188 0.747 3243 0.761 <br />Commemial/Ind ust rial/Institutional (acres) 100 0.13 95.89 0.156 85.89 0.1867 95.89 0.182 100.89 0.189 <br />Total Flows 0.508 0.779 0.9461 1.0341 1.0551 <br /> <br />Cumulative Flows (MGD) 0.967 1.566 2.1905 2.7232 3.0645 <br />Million Gallons Per Year 353 572 800 994 1119 <br /> <br />Source: City Engineer, Metropolitan Council, HKGi. <br />Note 1: Future MUSA expansions beyond 2015 will be studied as depicted in the Central <br />Planning Area Discussion on Page V-28 (see Figure V-3). <br />Note 2: Urban Residential Growth is assumed at 210 umts per year with the majority of new <br />units occurring in the Rum River Sewer District until after 2005. Residential flows are based <br />on an estimated 270 gallons per day per housing umt. Commercial absorption is estimated at <br />45 acres the Rum River District and 550 acres in the Mississippi River Sewer District. <br />Commercial flows are based on an estimate of 1,300 gallons per day per acres of <br />commercial/industrial/institutional development. <br /> <br />2001 Ramsey Comprehensive Plan <br />Amended February 26, 2002 <br /> <br />Page VIII-3 <br /> <br /> <br />
