City of Ramsey was based on a 1978 sewer report completed by the City, which identified three alternative sewer plans. Plan III was adopted by the City and was used for regional facility sizing. As mentioned previously, the MWCC sized two interceptors to serve the City of Ramsey. One 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. 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. The 1991 report explains 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 project, the MWCC has verbally committed to an allocation of 3.8 mgd or 48% of the City's ultimate design flow. On a local level, sewer planning will continue to be based on the ultimate average daily design flow of 7.87 mgd. On a regional level, the MWCC will be initiating a study to evaluate the capacity needs of regional facilities to determine what additional capacity allocation can be assigned to the City of Ramsey. It is anticipated that the study will be completed by the end of 2004. City of Ramsey Page 3-3 Comprehensive Sanitary Sewer Plan - 2004 Prepared by Bolton & Menk, Inc.
