<br />System Plan Considerations Affecting Your Community <br /> <br />1. Metropolitan Sewer Service <br /> <br />Forecasts: <br /> <br />The forecasts of population, households, employment, and wastewater flows for Ramsey <br />as contained in the adopted Water Resources Management Policy Plan are listed below. <br />These forecasts are for sewered development. The sewered housing forecasts were <br />estimated based on SAC data, annual city reports, current trends and other information <br />relating to your community. The wastewater flows are based on historical wastewater <br />flow data and the projected sewered housing and employment data. <br /> <br />Year 2010 2020 2030 <br />Sewered Population 21,164 38,839 42,644 <br />Sewered Households 7,500 14,000 16,000 <br />Sewered Emplovment 6,700 9,100 11,300 <br />Average Annual Wastewater Flow(MGD) 1.62 2.98 3.30 <br />Allowable Peak Hourly Flow (MGD) 4.7 7.75 8.58 <br /> <br />Table 1 <br /> <br />The flow projections represent the Council's commitment to a level of service, assuming <br />that the Council's underlying demographic forecasts are maintained. Adjustments maybe <br />required based on verified growth or lack of growth. The city should contact Council staff <br />to discuss any proposed adjustments. Flow projections do not represent an allocation of <br />interceptor capacity except in the event a temporary system constraint occurs. The <br />community must strive to keep its wet weather flows within the allowable peak hourly <br />rate. <br /> <br />At a minimum the Council will reevaluate flow projections every five years. Moreover, <br />the Council will also continue to monitor each city's flow on a continuous basis and note <br />any significant changes. The Council will use these growth arid wastewater flow forecasts <br />to plaIl- all future interceptors and treatment work needed to serve your community. The <br />Council will not design future interceptor improvements or treatment facilities to handle <br />peak hourly flows in excess of the allowable rate for your city. Ramsey, through its <br />comprehensive planning process, must decide the location and staging of development, <br />and then plan and design its local wastewater collection system to serve this development. <br />If you plan a total wastewater flow from your community in excess of the Council's <br />forecasts, your assumptions will be analyzed by the Council for their potential adverse <br />effects on the capacity or operation of the metropolitan system. <br /> <br />W- 2 <br />
