Pressure Sewer Systems, Septic Tanks & Gravity Sewer Systems
Septic Tanks vs Central Sewer Systems
Septic tanks have been a common method of residential sanitary waste disposal, but they may fail over time, polluting ground and recreational water and creating serious safety problems.
At South Cedar Lake in Minnesota, septic tank failures were often the result of the high water table. A group of homeowners decided to abandon septic tanks and chose E/One grinder pumps.
Many communities nationwide have banned septic tanks because they can fail and pollute groundwater.
Central sewer systems are a better choice for new home developments and are usually considered an attractive selling feature.
Gravity sewer systems may not be feasible for new construction projects: they can require large, deep trenches that make the project too expensive. Hilly land, rocky soil, or a high water table can add more complications. Pressure sewers can be installed in any terrain and need only small-diameter mains buried just below the frostline.
Residential Projects that use E/One Grinder Pumps
Above, Mike Mendelsohn, a builder in Arizona, describes how he used an E/One grinder pump on a rocky piece of land that also came with a lot of restrictions from the municipality, and was also below grade from the gravity sewer system. More information about Paradise Valley is available in our Case Studies section.
Benefits of E/One Grinder Pumps
- Sewer flat, hilly, rocky or wet terrain
- Low initial costs make central sewers economically feasible
- Central sewers increase the value of developmental units
- High reliability - maintenance is minimal
- Reduces operating costs
- Protective of public health
- Permits regulatory compliance
- Installation follows the contour of the land - needs only shallow trenches
- Labor and material costs are much less than gravity sewer systems

Frequently Asked Questions
Q: I need to maximize the value of the lots for my next project. Why would I consider E/One grinder pumps?
A: An E/One grinder pump system saves up front costs and long-term operation and maintenance costs, allowing you to create more lots in your development. Homes can be located in previously unusable locations where the terrain wouldn't allow a gravity sewer, so you won't have wasted space in the development. The system also gives you the flexibility to locate houses ar various distances from the main line pipes, restoration is quick and easy so you can vary the layout of your development, keep more trees and offer the scenic value that homeowners pay a premium for.
Q: Why can't I use a gravity system that is familiar to everyone?
A: Your development may be too rocky or hilly to install an effective gravity sewer system at a reasonable cost. Soil conditions may make gravity systems prone to water infiltration, which may cause overflow conditions and release pollution into the surrounding environment. With all the difficulties in obtaining choice development ground these days, gravity is not an option in some places.
Q: Why can't I use a septic system?
A: Septic tanks use valuable real estate, and soil conditions may not support a septic system. Septic systems require routine maintenance, are costly to replace, and can contaminate ground water. Due to pollution concerns, the Environmental Protection Agency routinely limits the use of septic systems. The E/One system is a cost-effective alternative to septic systems, designed to eliminate the pollution issues that could impact the quality of life in your community.
