A manhole giving access to a drain (e.g. for removing excess rainfall/water).
Also called storm drain, storm sewer (United States and Canada), surface water drain/sewer (United Kingdom) or stormwater drain (Australia and New Zealand).
How to map
More specific types can be described with:
If the grate is not made of a single material, but instead is covered in the same way as the surrounding surface, the values from the surface=* tag can be used inside of the material=* key (e.g. material=paving_stones). The additional details that follow that tagging scheme can also be used (e.g. paving_stones:pattern=*), however colour=* should be used instead of surface:colour=* (see above).
Possible tagging mistakes
- Although a kerb opening (inlet=kerb_opening) also collects storm water into a duct, it should not be tagged with either man_made=manhole or manhole=*, as it does not have a physical covering over the opening. If you see any uses of these tags in combination, please identify the actual inlet type, then correct the mistake.
- Although it may seem tempting, this tag is not to be used on long covered gutters that also act as a drain. It should only be used on manhole cover nodes. No consensus has been made on how to tag this feature but there has been some discussion on the Key:inlet talk page.
Drains come in different shapes and styles that can vary by placement (along a kerb, in the road, off the road), as well as by region. While not comprehensive, this table shows a variety of examples.
|man_made=manhole||A "grate" style drain, with thin bars and square shape.|
|A drain with thicker bars and openings.|
|man_made=manhole||A rectangular "slotted" style drain.|
|man_made=manhole||A circular drain in a larger paved area with large openings.|
|A circular drain with decorative emblem in the center, only small perforations.|
|man_made=manhole||A drain located in the street in Germany. Also with only small perforations. The bicycle emblem may signify that this style of drain is designed to be more bicycle friendly, lacking the "large slot" style that can catch thinner bicycle tires.|
|man_made=manhole||A kerb-located drain, with angled openings at the street surface. This style of drain often extends up the raised face of the kerb.|
