Sewerage

Sewerage refers to the infrastructure that conveys sewage. It encompasses components such as receiving drains, manholes, pumping stations, storm overflows, and screening chambers of the sanitary sewer. Sewerage ends at the entry to a sewage treatment plant or at the point of discharge into the environment. In loose American English usage, the terms "sewerage" and "sewage" are sometimes used interchangeably.
