Sewage Pumps
What is a sewage pump?
Sewage pumps are used primarily to move solid and liquid waste to a treatment location. Most municipal systems rely upon gravity to move waste from the drains of homes and other buildings to the local sewage treatment facility. However, it’s fairly common to have situations in which the sewage must be moved to a higher elevation or accross long distances and there’s not enough gravity-based pressure to do so. That’s where sewage pumps come in.
How do they work?
Most sewage pumps are submersible pumps, where the pump and motor are encased in a hermetically sealed chamber. The equipment sits at the bottom of the sump that is used to capture sewage, and it automatically turns on when the sewage rises high enough to trigger the power mechanism. In most smaller systems, the process is automated. There is an attached floating bulb that turns on the power when it rises above a certain level, and the power goes off when the bulb lowers below the shut-off level.
Where are they used?
Sewage pumps are used in private homes, commercial buildings, sewage lift stations, and sewage treatment plants. The pump is sized to handle a certain solids size, ranging from 2 inch for residential and light commercial applications, to 6 inch or larger for large municipal systems. For systems where it is desired to chop the solids, there are chopper pumps. Chopper pumps reduce solids into manageable pieces before pumping them. These are generally used in pressure sewer systems, sludge facilities, fertilizer processing facilities, or in waste processing for large agricultural applications.
