Interpretations and Explanations

A drain relies on gravity to work and is mainly used to remove waste water from a building, or from an industrial process in a commercial industrial installation. It is usually below ground. A drain can also be a small pipe used for example, for the removal of condensation from air-conditioning equipment (World Plumbing Council Working Group 2008).
