Drain

A channel, conduit, or pipe used to remove rain, wastewater, or sewage.

Drain

 

an artificial underground channel (pipe, cavity) for collecting and discharging subsoil waters and for aerating soil. Drains differ according to function (driers, collecting mains), structure, and materials. Pipes are made of such materials as earthenware, wood, and plastic. Cavities are of the mole or the slotted type, filled with gravel or fascines.
