t Metropolitan Council <br />Project the sewer <br />flow volume <br />Describe system <br />capacity <br />Include sewer flow volume projections based on the forecasted <br />growth for 2010, 2020 and 2030. For municipalities served by the <br />Metropolitan Disposal System, these projections are provided in <br />Appendix B -1 of the Water Resources Management Policy Plan. <br />Local Planning Handbook 1 Section 5 Water Resources Management <br />Since there is no preferred method for projecting sewer flows, each <br />municipality may use the method that is most appropriate. However, <br />the methodology and assumptions used must be explained in the <br />plan. <br />The description of the system's capacity includes all local, regional <br />and private wastewater systems operating in the municipality and <br />specifies all planned improvements. To meet these requirements, the <br />plan must include: <br />• Capacity and design flows for existing trunk sewers and lift <br />stations. <br />• The number of existing and potential connections for <br />each sewer service district in the municipality. <br />• Projected sewer flow volume in five -year increments <br />through 2030. <br />• The maximum projected sewer flow volume at whatever <br />point the municipality is designated as a fully developed <br />municipality. <br />• Proposed timing for the expansion of existing trunk <br />sewer pipes or construction of new trunk sewer pipes to <br />be connected to the Metropolitan Disposal System or to the <br />locally owned and operated wastewater system. <br />• Information on the type and capacity of all municipally or <br />privately owned treatment facilities, including a copy of <br />the municipality's National Pollutant Discharge Elimination <br />System (NPDES) or State Disposal System (SDS) permits. <br />http://www.metrocouncil.orc/plan <br />ning /environment/WRM PP /WRM <br />PPMay2005 Appendices2.pdf#p <br />aqe =7 <br />April 2008 5 -5 <br />
