C. "Other sewer issues" The memorandum states that the sYstem should be designed for its ultimate service function and~should not contemplate storage and off-peak pumping. Where was the author of that comment when capacity was allocated to Ramsey in the CAB Interceptor design? With specific allocations of capacity in the Metro facilities downstream, there are no planned MWCC facilities to accommodate more flow than Ramsey's proposed system is designed to accommodate. The possible need for off-peak storage and=pumping is created by the Metro Council and MWCC capacity allocation --not by Ramsey's design. "The 70 gallons per person per day flow assumption. It is felt that flow should be increased to reflect-Potential inflow-infiltration or that an additional infiltration factor'should be used in determining system sizing." With the downstream capacity established by theMetro Council and MWCC, the only purpose for any per capita flow assumption is estimating the areas that can be served by the available capacity. The '70 gallon per capita per day is consistent with metered flows from new systems serving similar communities in this area including infiltration/inflow. D. "Size of the proposed commercial area in the urban planning district." The thrust of the issue is that the commercial area is likely to over- load T.H. 47. If it is assumed that T.H. 47 will never be upgraded, the issue is well taken. If T.H. 47 is never to be upgraded, however, its capacity will be exceeded by Ramsey's projected population, regardless of the location or size of Ramsey's commercial area. It would appear that-the potential growth of Ramsey should keith caswell jr. ~] darrell schneider ~ richard sha
