Sump, sewage, and utility pumps drain liquids from flooded areas and basin sump pits to prevent flooding. Primary sump pumps drain water from sump pits in basements to prevent damage to homes and belongings. Sewage and effluent pumps dispose of wastewater from drains or septic systems. Marine bilge pumps remove water from the boat’s bilge compartment. Trash, dewatering, and utility pumps remove water that may contain solids from jobsites and remote locations. Sump and sewage pump switches and controls regulate when pumps start and stop, while alarms alert when flood conditions occur. Sink drain pump systems help remove wastewater from baths or sinks with below-grade drains, such as those in the basement of a house.
