E-One Grinder

E-One Grinder Pump

In order to provide wastewater disposal in some areas within the DWMF sewer service area, low pressure sewer systems are installed.  One type of grinder pump utilized within these systems is the Environment One (E-One) Grinder Pump.

The E-One grinder pump tank collects all solid materials and effluent from the house.  The solid materials are then ground to a small size suitable for pumping as a slurry with the effluent water.  The grinder pump generates sufficient pressure to pump this slurry from your home to the collection systems onto the wastewater treatment plant.With proper care and by following a few guidelines, grinder pumps will provide years of dependable service.

Care and Use of your Grinder Pump
The E-One grinder pump is capable of accepting and pumping a wide range of materials.  Regulatory agencies advise that the following items should not be introduced into any sewer, either directly or through a kitchen waste disposal unit:

  • Glass
  • Cotton swabs
  • Metal
  • Aquarium gravel
  • Seafood shells
  • Personal/cleaving wipes & sponges
  • Diapers, socks, rags or cloth
  • Plastic objects (toys, utensils, etc.)
  • Sanitary napkins or tampons
  • Disposable toothbrushes
  • Kitty litter
  • Cigarette butts
  • Syringes
  • Latex/vinyl items
  • Dental floss

In addition, you must never introduce into any sewer:

  • Explosives
  • Flammable material
  • Lubricating oil and/or grease
  • Strong chemicals
  • Gasoline

Items introduced into the sewer system from your home can potentially impact the water environment.  Proper disposal of household wastes such as window cleaners, unused/expired pharmaceuticals, paint thinners, fats, fruit labels, etc. is important.

Periods of Disuse
If your home or building is left unoccupied for longer than a couple of weeks, perform the following procedure:

Purge the System.  Run clean water into the unit until the pump activates.  Immediately turn off the water and allow the grinder pump to run until it shuts off automatically.

Duplex Units.  Special attention must be taken to ensure that both pumps turn on when clean water is added to the tank.

Caution:  Do no disconnect power to the unit.

Power Failure
Your grinder pump cannot dispose of wastewater without electrical power.  If electrical power service is interrupted, keep water usage to a minimum.

Pump Failure Alarm
Your E-One grinder pump has been manufactured to produce an alarm signal (120 volt) in the event of a high water level in the basin.  The installer must see that the alarm signal provided is connected to an audible and/or visual alarm in such a manner as to provide adequate warning to the user that service is required.  During the interim prior to the arrival of an authorized service technician, water usage must be limited to the reserve capacity of the tank.

E-One Maintenance Program
In order to join the E-One Maintenance Program, pumps must be purchased at DWMF and follow program protocol.  Pumps are sold at current market price.  Upon opting out of program, future tenants/homeowners will not be allowed back on program.  All agreements much be approved by DWMF.
