Environment One's business activity is comprised of two main segments:

Sewer Systems

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 9001:2008 certified.

Utility Systems

Environment One's expertise in the detection and measurement of submicron particles has led to the development of a line of critical monitoring instruments for electric utilities. The Generator Condition Monitor was designed to warn of potential failures in electric power generators by detecting the submicron particles emitted in the generator's cooling gas during early phases of overheating or arcing.

E/One's Utility Systems business is ISO 9001:2008 certified.
