Under the sewer pipe planned design in Figure 7-4, the system shows the same <br />pipes at capacity, with d/D ratios greater than 0.6. The planned design has all future <br />discharge connection points either to the Vadnais Heights or MCES connection systems. <br />7.3 Future System Needs <br />The Gem Lake sanitary sewer system was evaluated under the recommended peaking <br />factor for a City of this size per MCES standards. Capacity problems in the Southeast <br />District were identified. Future extensions to the existing piping network in this area will <br />need to address these pipe segments as part of any future construction. The future <br />conditions assessment of the system will be analyzed using those same peak flow factors <br />and the flow rates generated from new land use designations anticipated by the City <br />through the year 2040.
