The City's current <br /> estimates far future flows are based on a Residential Equivalent Connection <br /> (REC) value of 274 gpd. Table 4C-12 provides a summary of existing and <br /> projected flows for Orono by interceptor for the period 2008-2030, and compares <br /> this to the assigned capacity for Orono as indicated in the Met Council's 2005 <br /> Water Resources Management Policy Plan. <br /> Under current projections which include land use changes proposed in the Land <br /> Use Plan of this 2008-2030 CMP, potential Orono flow rates will slightly exceed <br /> _ the annual flows forecasted by Met Council through 2030, but do not exceed the <br /> Interceptor Design Capacity assigned to Orono as indicated in Table 4C-11. <br /> Table 4C-12: Review of Orono Sewer Connections Updated 3-]7-10 <br /> Sewer Connections and Wastewater Flows 2008-2030 (By Interceptor Service Area) <br /> Interceptor Se1'�'ice Area Existing Projected Connections (REC's) <br /> Connections <br /> 2oos(REC's) 2010 2020 2030 <br /> Metro Lift Station 59 (Orono) 1660 1690 1800 1835 <br /> Metro Lift Station 60(Long Lake) 502 585 1 122 l 173 <br /> Downstream Interceptors 270 289 376 401 <br /> (Direct connects to 7113 and 71 13A) <br /> Wayzata Direct Connections 70 89 ]28 12g <br /> Plymouth Direct Connections 5 5 5 5 <br /> Total REC's 2507 2658 3431 3542 <br /> Total Annual Flow Potential (MGY) 250.7 265.8 343.1 354.2 <br /> Avg.
