sanitary sewer
Underground drainage system
A sanitary sewer is an underground pipe system that carries wastewater from buildings—toilets, sinks, showers—to treatment facilities.
Distinguished from storm sewers, which handle rainwater, sanitary sewers transport only domestic and industrial sewage: The city's sanitary sewer system was built in the 1920s.
Sometimes called a foul sewer.
