E/One Sewer System image

E/One Sewer System

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.

E/One Grinder Pump image

E/One Grinder Pump

Sewage grinder pumps collect all of the wastewater from the home, grind up solids, and send the wastewater to the sewer line or treatment system. They are commonly used gravity sewer systems, septic tank and other wastewater systems cannot be used or are too expensive. 


The grinder pump is automatically activated and typically runs for very short periods several times per day. Electrical consumption of the grinder pump is low -  a household that uses 250 gallons of water per day should use between 6 kwhr and 23 kwhr per month to run the pump. (Actual water and power usage will vary depending on the system pressure.)

Extreme Series Accessories:  E/One Extender  image

Extreme Series Accessories: E/One Extender

The E/One Extender provides a quick and easy way to add 6 inches of height to an already-installed E/One grinder pump station.

If a grinder pump station has been installed too low into the ground -- where the lid sits directly on the grass, or slightly beneath the grass -- the station will be prone to infiltration. The vent may also be blocked, which could interfere with proper pump operation. The solution? The E/One Extender. The pre-engineered E/One Extender provides protection and meets warranty requirements for most Extreme and 2000 Series grinder pump stations.
