Proper sewage disposal and treatment is an integral part of keeping any community healthy. One great way to properly dispose of sewage for homeowners in the St. Louis area? Residential grinder pump systems. This method of waste disposal is perfect for homes that are part of a lower-pressure sewer system, are located downhill from a sewer main, or for when it is not otherwise feasible to install a gravity sewer line.

  • Submersible grinder pump stations
  • Sewage grinder pumps

Grinder pump systems are methods of controlling waste for both commercial and residential properties.

They work like this:

  • Waste—including human waste and wastewater—collects in a holding tank, which is often made of fiberglass.
  • When the collecting tank reaches a certain capacity, the (usually exterior) control panel automatically kicks the centrifugal pump into gear. Impellers (usually made of cast iron or stainless steel) turn wastewater and solid wastes into a slurry.
  • A simplex or duplex lift station transports the slurry to a public sewage system or wastewater treatment plant.

The primary advantage of grinder pump systems over other popular methods of waste disposal, including sump pumps and sewage ejector pumps, is that grinder pumps can break down waste to a more manageable size, which can help save water and reduce the likelihood of clogs. The disadvantages of grinder pumps, however, are that they often produce greater horsepower than sump and sewage pumps, meaning they use more electricity. Furthermore, they are not ideal to use with septic tanks, as septic systems need solids and liquids to be separate in order for proper waste treatment to occur, which isn’t possible with the slurry produced by grinder pumps.
