Wastewater Grinder Pump Information

General Information

In order to provide you with suitable wastewater disposal, your home is served by a low-pressure sewer system. The grinder is the key element in this system. The 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 wastewater treatment receiving line and/or disposal plant.

With proper care and by following a few guidelines, your E-One grinder pump will give you years of dependable service.

Care and Use of your Grinder Motor

The 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
  • Metal
  • Plastic objects (toys, utensils, etc.)
  • Dirt or Sand
  • Seafood shells
  • Eggshells
  • Diapers, socks, rags or cloth
  • Sanitary napkins or tampons

In addition, you must NEVER introduce into any sewer the following:

  • Explosives
  • Strong
  • Chemicals
  • Gasoline
  • Flammable Material
  • Lubricating oil and/or grease

Any damage caused to personnel or by unauthorized entry into the sewer system will be charged to the customer. Any repairs due to materials found in the care and use category will be the responsibility of the customer.

Your grinder motor service is subject to the Rates, Rules, and Regulations adopted by the Bastrop County WCID #2.

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.

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 grinder pump has been designed 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.
