CMP Part 4B. Sanitary Sewer Plan <br /> Population <br /> The Metropolitan Council publishes population and sewer usage forecasts for each city in the <br /> Metropolitan Area. MCES use these growth and wastewater flow forecasts to plan future <br /> interceptor and treatment works to serve communities.The forecast data in the table below is from <br /> the Metropolitan Council's Local Planning Handbook Community Page for Orono and includes <br /> both total and sewered population, households, and employment. <br /> Table 0-4: Orono Population and Households 1970 -2040 <br /> (Sewered and Unsevered Forecasts) <br /> Population <br /> Year 1970 1980 1990 2000 2010 2016 2020 2030 2040 <br /> Sewered - 4,429 5,150 6,170 6,740 <br /> Unsewered -- -- -- -- 3,008 -- 2,950 2,630 2,760 <br /> Total City 6,787 6,845 7,285 7,538 7,437 7,691 8,100 8,800 9,500 <br /> Household <br /> Year 1970 1980 1990 2000 2010 2016 2020 2030 2040 <br /> Sewered -- -- -- -- 1,780 2,105 2,455 2,785 <br /> 2,253 <br /> Unsewered -- -- -- -- 1046 784 1,095 1,105 1,115 <br /> Total City 2,146 2,291 2,613 2,766 2,826 3,037 3,200 3,560 3,900 <br /> Persons/HH 3.16 2.99 2.79 2.73 2.63 2.53 2.53 2.47 2.44 <br /> Source: Metropolitan Council <br /> Wastewater Flows <br /> All of the existing and anticipated sewage flow from the City of Orono is treated at the Blue Lake <br /> WWTP. The treatment plan currently processes 26 Million Gallons Per day and has a planned <br /> capacity of 40 million gallons per day by 2040 (Council, 2016). The CSPP element of the 1980 <br /> CMP indicated an ultimate interceptor design capacity assigned to Orono of 3,025 units based on <br /> a flow of 368 gpd GPD per unit (115 gal/person/day x 3.2 persons/household) totaling 1.14 mgd <br /> or 416 million gallons per year(MGY). Under current projections which include land use changes <br /> proposed in the Land Use Plan of this 2018-2040 CMP, potential Orono flow rates will slightly <br /> exceed the annual flows forecasted by Met Council through 2040 but remain below the ultimate <br /> design capacity. The paragraphs and tables below depict the MCES and Orono projections. <br /> MCES Projections <br /> Table 4B-5 below lists projected total average wastewater flow for Orono. <br /> City of Orono Community Management Plan 2020-2040 Part 4B, Page 8 <br />
