    Tips: What is a Sewage Pump?

    A sewage pump is a compact appliance with a specific job. Sewage pumps handle black water waste, which means waste that is sufficiently toxic to need a separate routing system. The most common source of residential black water waste comes from the commode. For commercial operations, commode black water waste may be joined by other pathogen-contaminated wastewater.

    A sewage pump's job is to prepare black water waste for transport and then assist in that transport. To do its job, a sewage pump may need to handle solid waste of varying sizes and consistencies along with liquid wastewater.
