Sewer Systems


If you are connecting to the municipal sewer system or have a home (or home site) that is located below grade, we can help. Learn the benefits of ALL-TERRAIN SEWER® system for long-term reliability vs septic tanks.

About Your E/One Grinder Pump

The ALL-TERRAIN SEWER pressure sewer system consists of small-diameter pipes and E/One grinder pumps, allowing wastewater to be pumped uphill, across flat land, or even to the other side of the road to the sewer main. This is different from a gravity sewer system, where all pipes slope downhill, often to a large lift station, then to the wastewater treatment plant.

The grinder pump is installed at your home (either in the basement or in the yard), grinds up wastewater and pumps it to treatment or a sewer main. An E/One Sewer system offers lower cost, less disruption to the landscape, greater reliability and protection for the environment.

Frequently Asked Questions

Q: Where do I go for service? Can I call any plumber?
A: E/One recommends that you call an authorized distributor for service. Our distributors – and their network of service providers – are trained in troubleshooting and repair of E/One grinder pumps. Visit our grinder pump service page for more information and to find a grinder pump service provider. Contact us if you need additional information.

Q: Can a grinder pump be installed for just one home, or does the entire neighborhood have to have grinder pumps?
A: If you can pump to a sewer main or treatment, a grinder pump can be installed at one home. This is particularly attractive if your home is "below grade" (lower than the sewer main) or on the other side of the street from the sewer main.

Q: How do I know if my grinder pump is working? How do I know if my grinder pump has stopped working?
A: E/One grinder pumps come with an alarm panel. If your grinder pump is working properly, you shouldn't notice it at all — the pump will turn on as needed and pump down the tank; its noise level is similar to that of a washing machine. The pump should turn off after a few minutes. If your pump should stop working, the alarm panel's red light will blink, and a buzzer will sound. If the alarm doesn't turn off after a few minutes, you should call for service. Also look on your panel box for the Service Link phone number.

Q: Am I limited to what I can put down the drain?
A: The grinder pump will handle all typical household waste. However, you should not allow strong chemicals, oils, diapers, plastics, etc. to enter the pump station. Refer to the User Instructions on our Service page for more information. Our grinder pump Owners Guide is also helpful.
