Wastewater Plan <br />Overview and Background <br />Growth of population and jobs in a community can present challenges to ensuring the needs of <br />residents and businesses are adequately met. One of the key elements in addressing this challenge <br />is the planning, construction, and maintenance of adequate wastewater collection systems. A <br />Wastewater and Comprehensive Sewer Plan is a useful tool for defining the strategies the City will <br />use to accomplish planning, construction, and maintenance of the wastewater system. <br />Under the state Metropolitan Planning Act, local governments are required to submit a wastewater <br />and comprehensive sewer plan element as part of their overall comprehensive plan. This includes <br />describing service needs from the regional system in support of planned growth. Prior to any <br />expansion of sanitary sewer service, this plan must be found consistent with the regional 2040 <br />Water Resources Policy Plan produced by the Metropolitan Council. <br />In 2005 the City of Ramsey completed a Comprehensive Sanitary Sewer Study which was prepared <br />by consulting engineers Bolton & Menk, Inc. The 2005 Plan presented a guide plan for the extension <br />of the sanitary sewer trunk system to the entire City. In 2012 the City updated the 2005 <br />Comprehensive Sanitary Sewer Study. This update focused on the proposed sanitary sewer trunk <br />extensions and improvements which are required to provide service to all areas within the 2030 <br />MUSA boundaries. In September, 2017, the City completed an update to the 2012 Comprehensive <br />Sanitary Sewer Study. The 2012 study and 2017 update identified the ultimate sanitary sewer <br />flows for the City. The City of Ramsey is considered by Metropolitan Council to be a "Developing <br />Community" and as such is presently allowed to extend sanitary sewer service anywhere within <br />MWCC Sanitary Sewer District 3 boundary (south of Trott Brook). The current extent of the <br />sewered area is now adjacent to Trott Brook and revised land use plans require its extension to the <br />remaining portion of the City. The City's current wastewater flow allocation is 3.8 million gallons <br />per day (mgd). <br />The 2017 update to the Comprehensive Sanitary Sewer Study completed by Bolton & Menk Inc. is <br />incorporated in this Plan in Appendix B. Revised sanitary sewer flow projections based on the <br />revised Future Land Use Map are included as Exhibit 8:1 of this Chapter. The flow assumptions for <br />calculating sanitary sewer flow are as follows: <br />Description Factor <br />Gallons per Person per Day 75.0 <br />Flow Variation Factor 2.5 to 4.0 <br />People per Unit 3.0 <br />Flow per unit 225 <br />Employees per Acre 20 <br />Commercial/Industrial Flow per 1,500 <br />Acre <br />Cily of RAMSEY <br />August 2018 Draft <br />Comprehensive Plan 2040 <br />
