Septic to sewer conversion programs? Excessive I&I into your gravity sewer system? Concerns about life cycle costs? With 50 years of experience and eco-innovations, E/One has designed intelligent sewer systems that work on a truly massive scale.
Communities around the world have used E/One Sewer systems — whether they are replacing septic tanks, upgrading existing pressure sewer systems, or as an alternative to gravity sewer systems. The ALL-TERRAIN SEWER pressure sewer system from E/One offers a cost-effective alternative to gravity sewer systems because pressure force mains follow the contour of the land and need only to be installed just below the frost line, making it ideal for terrain that is flat, wet, rocky or hilly.
Pressure Sewer Systems vs. Gravity Sewer Systems
Gravity sewer systems are the "original" central sewers, with origins in the Roman aqueducts. They must be accurately bedded along a continuous downward grade and often involve very deep trenches — 20 feet or more — and large, costly lift stations. Installation and operating costs have become so exoribitant that pressure sewer has become the go-to sewer system of choice for many municipalities.
Below, FUD Knox Country, Tennessee, discuss their E/One and ALL-TERRAIN SEWER experience.

Upgrade Grinder Pumps in a Pressure Sewer System
If your community already has a pressure sewer system and needs to replace failing centrifugal grinder pumps, E/One has a solution. E/One's Upgrade pump was designed specifically for existing grinder pump sewer systems. The pump is engineered to fit into virtually any other wet well tank, allowing for easy drop-in installation.

Frequently Asked Questions
Q: Who owns/maintains the grinder pump stations?
A: The grinder pump stations may be owned by the council/water authority (and the pressure pipe on private property), or by the homeowners individually. In the first instance, the municipality would maintain the grinder pumps, and E/One's local distributor would keep the municipality up to date on training and product changes. If the homeowners own their individual grinder pumps stations, then they would be responsible for all installation and maintenance costs.
Q: What about backups? How can we be responsible for a homeowner who may continue to use water when a pump is down, creating a backup?
A: If the grinder pump stations are owned by the municipality, it is in the homeowner's own best interest to alert the authority as soon as possible when the high level alarm is audible. Education of the homeowner is key. In the event of an alarm condition, the homeowner should minimize use of water within the home until repairs are completed.
If the homeowners will be individually responsible for their grinder pump stations, it's still a good idea to educate them at the beginning of the project about the grinder pump stations. Our Owners Guide offers a basic description of the E/One grinder pump and answers common questions.
