3.2Watermain <br />Watermain does not currently exist under Garnet Street. However, 8” DIP watermain stubs exist <br />atbothends of the project termini on Garnet Street. Staff recommends extending 8” DIP main <br />under Garnet Streetwith this project to provide a looped watermain system. This will allow for <br />better maintenance of the water supply system, as well as allowing for smaller areas of isolation <br />when parts of the main need to be shut down for maintenance. <br />th <br />Watermain does not currently exist under 168Avenue.However, 8” DIP watermain is planned <br />th <br />to be extended to the west end of 168Avenue through the Brookfield residential development. <br />Therefore, if 8” DIP watermain is extended under Garnet Street per staff’s recommendation, staff <br />th <br />would also recommend extending8” watermain under 168Avenue to connect to the Garnet <br />Street watermain, thereby providingafully integrated watermain systemto allow for better <br />maintenance of the water supply system, as well as allowing for smaller areas of isolation when <br />parts of the main need to be shut down for maintenance. <br />Ifwater mainis constructed with this project, field observations and soil compaction testing <br />would need to be completed during soils excavation work. <br />As previously noted, groundwater is not anticipated to be an issue during water main work. <br />3.3Sanitary Sewer <br />Sanitary sewer does not currently exist under Garnet Street. However, 8” PVC gravity sanitary <br />sewer stubs doexist at both ends of the project termini on Garnet Streettherefore trunk sanitary <br />sewer could beinstalled with this project. <br />th <br />Sanitary sewer does not currently exist under 168Avenue. However, 8” PVC gravity sanitary <br />th <br />is planned to be extended to the west end of 168Avenue through the Brookfield residential <br />development. Therefore, 8” PVC sanitary sewer will be available in the future at the west end of <br />th <br />168Avenue. <br />If sanitary sewer is constructed with this project, field observations and soil compaction testing <br />would need to be completed during soils excavation work. <br />As previously noted, groundwater is not anticipated to be an issue during sanitary sewerwork. <br />Feasibility Report <br />th <br />Garnet Street and 168Avenue Reconstruction <br />City of RamseyProject No. 13-10 <br />Page 7 <br /> <br />
