Sewer Systems

E/One Grinder Pumps

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 otherwise 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 1 million end-users daily. E/One’s Sewer Systems business is ISO 9001:2015 certified.


E/One sells its grinder pumps through a network of distributors.


Correct Equipment proudly sells, installs, and services E/One grinder pumps and sewer systems within Oregon and Washington. These modern systems are highly reliable central sewer systems that allow developers and prospective home builders to use virtually any plot of land, regardless of terrain or elevation changes. Sewer systems using E/one grinder pumps are much more affordable than conventional gravity sewers, which require major excavation, and much safer for communities than septic systems, which can eventually fail, polluting ground and recreational water and endangering public health.
