An aqueduct is a structure for conveying water over a distance, typically using bridges to cross valleys and ravines. This tag doesn't require the aqueduct to be still working, it can also be applied to ruins and fragments.

Modern pipelines and canals are sometimes also called aqueducts, but this tag only deals with historic aqueducts. Unlike modern aqueducts they are still referred to as aqueducts even if there are only fragments left and they can't serve their original purpose.

See also bridge=aqueduct - for the bridge part of the aqueduct which carries a functioning artificial waterway

How to map

Draw a way way along the aqueduct, or draw a closed way area around its outline. Tag with historic=aqueduct.

Tags used in combination

Other properties might be (if you know them, tag them):

  • name=*
  • historic:civilization=* for the culture that originally constructed the aqueduct, e.g. ancient_roman
  • start_date=* for the time when the aqueduct started to work
  • bridge=aqueduct for parts of an aqueduct that are bridges (note that not all historic aqueducts are bridgelike structures, and not for all their way).
  • ele=* if you know the elevation of distinct points of the aqueduct (level of the water / where once the water was) you can tag them like this
  • ruins=yes if it is ruined
  • wikipedia=* a link to Wikipedia's article about the feature

In some cases you might want to add

  • heritage=* if aqueduct is registered by an official heritage organisation.

Using relations

Aqueducts generally tend to be long. Nowadays many of them are not entirely preserved, but you will find fragments. It is suggested to use a relation (to be defined) to join all aqueduct parts that once were continuous into one object, even if now they don't form a continuity.
