interceptor sewers accept all of the sewer flow south of Trott Brook. Based on information provided by City Staff, it has been assumed that the properties north of Trott Brook contain approximately 3,800 acres of developable land that could be developed with a density of 2.3 units per acre. Based on this density, the area north of Trott Brook would be developed with approximately 8,800 units and would support a maximum population of approximately 26,400 people based on 3.0 people per unit. At this time, it is anticipated that any sewer treatment for the area north of Trott Brook would be treated at a facility owned and operated by MWCC and located within the North Trott Brook Service Area. F. RUM RIVER SEWER DISTRICT The Rum River Sanitary Sewer District shown on Figure 1 contains approximately 5,610 acres of developable property. It is anticipated that at ultimate development this area can support approximately 15,401 residential units with a maximum population of 46,203 based on 3.0 people per unit. The ultimate sewer flow for the Rum River District is estimated to be 3.64 mgd. This total consists of 3.46 mgd residential flow, 0.14 mgd commercial / industrial flow, and 0.04 mgd of special use flow. It is proposed that the existing 30 -inch interceptor sewer accept all of the sewer flow from the Rum River District. Smaller local interceptors are proposed to serve the local sewer sub -districts. G. MISSISSIPPI RIVER SEWER DISTRICT The Mississippi River Sanitary Sewer District shown on Figure 1 contains approximately 4,354 acres of developable property. It is anticipated that at ultimate development this area can support approximately 9,309 residential units with a maximum population of 27,927 based on 3.0 people per unit. The ultimate sewer flow for the Mississippi River District is estimated to be 3.68 mgd. This total consists of 2.20 mgd residential flow, 1.45 mgd commercial / industrial flow, and 0.03 mgd of special use flow. It is proposed that the existing 30 -inch interceptor sewer accept all of the sewer flow from the Mississippi River District. Smaller local interceptors are proposed to serve the local sewer sub -districts shown on Figure 3. City of Ramsey Page 2-5 Comprehensive Sanitary Sewer Plan - 2004 Prepared by Bolton & Menlc, Inc.
