What type of sewer system will be installed?
With the exception of the main trunk line to Manchester, the sewer system will be a low pressure sewer (LPS) system. The LPS system uses small diameter (2- to 4-inch) pipes and grinder pumps at each building. The grinder pumps are installed to provide the pressure to pump the wastewater to a main pump station along Route 44 west of the lakes, which in turn will pump the wastewater to Manchester. Why are low pressure sewers being used? A low pressure sewer system allows sewer piping to follow the natural topography of the land, and uses much shallower and smaller diameter piping than conventional gravity sewers. This will be significantly less disruptive and less expensive around the lakes compared to a gravity sewer system, which use larger diameter, deep pipes. Also the LPS system will avoid the need for multiple larger pump stations around the lakes. What do I need to know about grinder pumps? Your grinder pump will be situated in a chamber located outside your house or building, and
