Many of the properties will require individual pump stations to pump the wastewater to the sewer line in the roadway. This will include those properties on West Lakeshore Drive that are lower than the roadway, (generally the lake side of the roadway) and also, all of the properties on East Lakeshore Drive and Goodsell Point where low-pressure sewers will be used. Because these sewer lines are pressurized, individual properties must pump into them regardless of elevation. Low pressure sewers were chosen for these areas as they can be installed at much shallower depths and do not require large pump stations. These factors are important considering traffic impacts during construction, limited working space, and ledge. Once the project is completed, the individual service lateral, including individual pumps will be the responsibility of the property owner. The pumps are a pre-packaged unit that are approximately 4 feet in diameter, and about 7 ½ feet high. They have significant emergency storage in the event of a power outage, and operate quietly and efficiently, without odor. The units will be located outside of the houses and below ground surface. They will have an at grade cover on them and will look similar to a septic tank cover. Addition technical information about these individual pump stations can be viewed here.
