connection designed to serve the City's Rum River Sewer District, was designed for an average daily flow of 3.95 mgd. The other connection designed to serve the City's Mississippi River District, was designed for an average daily flow of 3.92 mgd for a combined ultimate average daily design flow of 7.87 mgd. According to the 1991 Comprehensive Sewer Plan, the metro agencies have recognized the potential for an average daily flow of 7.87 mgd from the City of Ramsey. This Study projects an average daily flow of 7.568 mgd from full development of the entire City (from Table 2.3) which is essentially the same as the 1991 Plan. However, at the time of the 1991 report the capacity that was allocated to the City in the Anoka Lift Station and CAB interceptor was only 2.8 mgd or approximately 35% of the City's ultimate design flow at that time. The 1991 report explained that the regional facility sizing was based on a conscious decision by the metropolitan agencies to minimize capital expenses by constructing facilities sized to meet the flow projections for specified planning periods, not ultimate flows. This is based on the assumption that not all communities will develop to their ultimate potential. However, as a result of the review process for the AUAR that was completed for the Ramsey Town Center (now CORE) project, the MWCC committed to an allocation of 3.8 mgd or 50% of the City's currently projected ultimate design flow. The City of Ramsey is now considered to be a "Developing Community" by the Metropolitan Council. The designation originally allowed the City to extend sanitary sewer service anywhere within MCES Sanitary Sewer District 3 boundary (south of Trott Brook). Previous studies indicated that the area north of Trott Brook would be serviced by a proposed regional waste water treatment plant. Now, according to the Metropolitan Council, regional capacity for the north Trott Brook area can be provided through the existing Regional Disposal System by system capacity improvements. Therefore a future Regional waste water treatment plant is not being planned The Metropolitan Council policy now provides the City flexibility to extend sanitary sewer City of Ramsey Page 3-3 Comprehensive Sanitary Sewer Plan - 2012 Prepared by Bolton & Menk, Inc.
