III. Sanitary Sewer The proposed sanitary sewer for the Homestead Road area is shown on Figure 2. A review of the project site indicates the routes shown on the figures are recommended from a construction staw4>oint. If sanitary sewer is ever required to serve the properties in the Farm at Long Lake nei^bortiood to the north a similar sewer alignment should be considered along West Farm Road. Figure 2 shows a pressure sewer system. The proposed pressure sewer would be constructed primarily along the south side of Homestead Road. The sewer would be directionally bored to minimize property disturbance and associated restoration. The pressure sewer would be 1 Vi” to 2” diameter HDPE pipe. Sewer services provided to properties on the nonh side of Homestead Road would be directionally bored to eliminate street restoration costs. Sewer services would be extended to each property, terminating with a curb stop (shut off) at the property line. All flows will be directed to the existing city owned forcemain located under the existin z bituminous trail along the west side of North Brown Road. A residential grinder station that would pump flows from the home to the curb stop is required to serve each property. Each resident would be responsible for all costs associated with the purchase, installation, maintenance and operation of the grinder station. The residents would also bear the cost for the installation of the service line between the grinder station and the sewer stub at the property line. These costs are not included in the project cost and have ranged from $7,500 to $12,000 on previous projects. If the project moves forward, homeowners are encouraged to consult a plumber to estimate these costs for their situation. All disturbed areas will be restored as part of the project. The existing trail along North Brown Road will be disturbed to make the connection to the forcemain. The trail will be patched and disturbed areas adjacent to the trail will be sodded. Disturbed boulevard areas along Homestead Road will be sodded or reseeded. A gravity sewer system was considered as an alternative to the pressure sewer option. The existing •• topography in the Homestead Road neighborhood along >^ith the elevation of the nearest downstream gravity manhole would require the construction of a lift station to serve this area. The gravity sewer would be installed in the roadway requiring street reconstruction with limited residential access during construction.
