E/One Sewer Systems: Environmentally Sensitive, Economically Sensible The E/One Sewer system is a pressure sewer system that is powered by E/One grinder pumps. A pressure sewer system uses small-diameter pipes and grinder pumps, which are often installed at each home. The grinder pump station collects all of the wastewater from the home and grinds it into slurry. The wastewater is then pumped to a larger sewer main or directly to a wastewater treatment plant. While gravity sewer systems often use large mains that are installed in deep trenches, pressure sewer pipes may be as small as 2 inches in diameter and follow the contour of the land. These small trenches can equal huge savings. Pressure sewer systems are used in areas where a conventional gravity sewer system cannot be installed, or is too expensive to do so. The land may be very flat, rocky, hilly, or wet. Benefits of E/One Grinder Pumps include: -Sewer flat, hilly, rocky or wet terrain -Low initial costs make central sewers economically feasible -Central sewers increase the value of developmental units -High reliability ? maintenance is minimal -Reduces operating costs -Protective of public health -Permits regulatory compliance -Installation follows the contour of the land ? needs only shallow trenches -Labor and material costs are much less than gravity sewer systems E/One Sewers are truly the environmentally sensoitive, economically sensible way to go!
