What is a low-pressure sewer system?

The E/One Sewer system is a low pressure sewer system that is powered by E/One grinder pumps. A low 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.

Low-pressure, gravity-independent, contour-following sewage collection systems were pioneered by Environment One. E/One Sewer® systems have proven to be an economical and effective method of sewering even in difficult land areas, such as flat, wet, rocky and hilly terrain.

At the heart of an E/One Sewer® is the Grinder Pump, developed by Environment One. These units accept household sanitary waste, grind it into a fine slurry, and pressurize it to permit transport through small-diameter pipes. E/One Sewer Systems serve over 500,000 end-users daily.

Gravity vs. Low-Pressure

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. Installation using these small trenches can equal huge savings in development costs.
