Etymology

Origin of sewage

1825–35; sew(er) 1 (as if the ending was -er 1 ) + -age

Explanation

The waste water that flows down drains and through pipes from toilets and sinks is called sewage. There's nothing quite like smelling sewage on a hot summer day. Have you ever wondered where the soapy, dirty water from your washing machine goes after your clothes are clean? It flows down the drain into a pipe, and is carried with other sewage out to the street and your city's wastewater system, or into a private septic tank. Sewage comes from the now-obsolete verb sew, "to drain or draw off water."
