A grinder pump is a wastewater pumping system that uses a device called a grinder to chop wastewater into small pieces before pumping it to the sewer. This helps prevent clogs in the sewer line. The main benefit of using a grinder pump is that it can handle solids (like toilet paper, human waste, and rags) that would otherwise cause clogs and backups in the municipal sewer system. A grinder pump also helps reduce the time needed for sewage to travel from your house to the municipal sewer.
A Grinder Pump is generally needed when the wastewater from your home exceeds your municipal sewer system’s head and pumping capacity. Sewer systems are designed for a certain amount of wastewater flow, and when that limit is exceeded, the excess wastewater needs to be handled by a Grinder Pump. It will chop up any large pieces of debris (like wipes, sanitary napkins, condoms etc.) so that they can be easily pumped out and disposed of properly. It’s important to note that while a Grinder Pump can help handle excess wastewater, it should not be considered a replacement for proper waste handling practices – like only flushing toilet paper down the toilet!
This important system should be installed whenever a lift station is required, meaning the wastewater needs to be pumped more than ten feet vertically or more than 100 feet horizontally from the septic tank or collection tank. In some cases, a grinder pump may also be needed when the house is not located on a gravity-fed sewer system. For example, if there is a large amount of groundwater or the soil is too loose to allow proper infiltration, a grinder pump may need to be installed.
