A drain is the primary vessel or conduit for unwanted water or waste liquids to flow away, either to a more useful area, funnelled into a receptacle, or run into sewers or stormwater mains as waste discharge to be released or processed. In some countries a distinction is made between foul water drainage (which removes water from sinks, toilets and plumbed appliances etc.) and surface water drainage (which removes rainwater from surfaces).
