Tag:man_made=sewer_vent

A sewer vent, sewer vent pipe, sewage vent, stink pipe or stench pipe is a chimney often found in the streetscape, made from cast iron. From the bottom, it might look like an old or broken street lamp, and it often has a cage on top to prevent birds from falling in. They are sometimes protected and to be found on a local heritage register.

How to map

Set a node at the location of the sewer vent and add man_made=sewer_vent.
