<br /> <br />Feasibility Report <br />2021 Street and Utility Improvement Project <br />City of St. Anthony Village <br />WSB Project No. 015900-000 PAGE 9 <br />4.3 CHANDLER DRIVE AND FOSS ROAD SANITARY SEWER IMPROVEMENTS <br /> <br />Based on the drawdown tests performed, the Foss Road lift station firm pumping capacity (the capacity of <br />the station with its largest pump out of service), is 1,014 gpm. The post-development peak hourly flow for <br />the Silver Lake Village Area is 1,195 gpm. The firm pumping capacity should equal or exceed the peak <br />hourly sanitary flow of the Silver Lake Village Area post development. Improvements to the lift station to <br />accommodate the Silver Lake Vilage Area development include replacing the lower capacity pump with a <br />1,400 gpm to 1,500 gpm pump. <br /> <br />In addition, the undersized segment of sanitary sewer along Chandler Drive is proposed to be replaced <br />with the improvement ptoject to provide adequate capicaity for the Silver Lake Village Area development. <br />The proposed Chandler Drive and Foss Road sanitary sewer improvements are shown on Figure 7 in <br />Appendix A. <br /> <br /> <br />46
