III. Sanitary Sewer The proposed sanitary sewer for the Bracketts Point area is shown on Figure 2. A review of the project site indicates the routes shown on the figures are recommended from a construction standpoint. The Bracketts Point area would be served by construction of a lift station located approximately 600 feet south of County Road 15 on Bracketts Point Road. A force main would be installed along Bracketts Point Road north to County Road 15 (Shoreline Drive) and connected to an existing MCES force main. Gravity sewer will carry all flows to the lift station. The property located on the east side of the project (see Figure 2, property 11) will need to be served by a residential lift station due to the elevation of the existing structure. All other properties within the project will have gravity services. An alternate design for the sanitary sewer south of the proposed lift station is shown in Figure 3. Properties in the south half of Bracketts Point would be served by individual grinder pumps. A force main would be installed on the east side of the roadway north to the lift station. This alternate design would decrease the initial cost of the project slightly. Grinder pump operation and maintenance would be the responsibility of the property owner. A cost estimate for the alternate design is included in the appendix. Sewer service for each home will consist of a 4-inch PVC line. Services will be extended to the property line. The property owners will be responsible for the connection to the service. The City will provide a grinder pump station as part of the overall project cost for the property owners that cannot be served by gravity. The installation of the grinder pump will be a responsiblity of the property owner. The project will generally be constructed within the right-of-way of existing streets where possible. The alignments selected and shown on Figure 2 will require some permanent and temporary easements to allow for construction. The streets will be restored to 22 feet wide with 1 V2 inches of bituminous wear course, 2 inches of bituminous base course, 8 inches of aggregate base, 100 % crushed material and geotextile stabilization fabric. Detailed cost estimates for the sanitary sewer improvements are presented in the Appendices. Bracketts Point Sanitary Sewer Improvements
