The E/One Pressure Sewer System

We’ve perfected the most-rugged, longest-lasting sewer system in the industry. This economical and highly reliable central sewer system can be installed on any terrain - flat, wet, rocky, even on sites with dramatic elevation changes. The Extreme Series grinder pump, the heart of E/One’s sewer system, is the global leader in reliability and economy. This progressing cavity pump’s evolution reflects everything we’ve learned in over a half century as the originator and leader in pressure sewer system technology.

E/One Sewer Systems are the solution of choice to serve some of the world’s most extreme environments and most exacting communities, serving well over 2 million end users daily. Choose E/One to empower your next project with the lowest lifecycle cost while protecting environmental quality of life.

How Does The E/One Sewer System Work?

  • An E/One grinder pump appliance, installed at each property in the system, accepts gravity-fed wastewater from each building.

  • After being ground and pressurized, the wastewater slurry enters a sealed small-diameter pipe network installed just below the ground’s surface or frost line.

  • Following the natural contour of the land and because the output is pressurized, the wastewater can be transported horizontally over two miles or uphill 185 feet vertically.

  • Ultimately the pipe network may feed into a larger collection system, either an existing gravity system or pressure main, or even directly into a wastewater treatment plant.

What is the Difference Between a Gravity Sewer System and a Pressure Sewer System?

Gravity sewer systems often use large pipes that are installed in deep trenches and must follow a constant downslope. Low pressure sewer pipes may be as small as 2 inches in diameter and follow the contour of the land -- up and down hills, or across flat land at a constant depth. These small trenches can equal huge savings in installation costs.

Low pressure sewer systems are often used when a gravity sewer system cannot be installed, or is too expensive to do so. The land may be very flat, rocky, hilly, or wet.
