|inlet = grate|
|A horizontal grate that covers sumps, tunnels or culverts, on pavements or in a street to catch storm water.|
|Group: Man made|
|Used on these elements|
|Tools for this tag|
are installed over storm drains to cover sumps on pavements or in streets to prevent debris and people from going down the drain. They are mostly horizontal.
Often grate covered inlets are found next to kerbs, but with an attached section of kerb, these should be tagged as inlet=kerb_grate, instead. See examples on the inlet=kerb_grate wiki page for a deeper explanation. Only use inlet=grate, when the grate is not connected to a section of the kerb, made out of the same material.
Tagging a manhole drain
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).

|UK||man_made=manholemanhole=drain||Grate inlets at the side of roads or pavements (that may be connected/adjacent to the kerb) should not use inlet=kerb_grate, unless the grate is also connected to a section of the kerb (made of the same material). See examples on the inlet=kerb_grate wiki page for a deeper explanation.|
See the manhole=drain wiki page for more examples.
Incorrect use on a covered gutter
Although it may seem tempting, this tag is not to be used on long covered gutters that also act as a drain (see example image below) when they are mapped using ways. It should only be used on inlet drain nodes. No consensus has been made on how to tag this feature but there has been some discussion on the Key:inlet talk page. Whichever tagging method is decided upon, man_made=manhole and manhole=drain should not be used, as the way is not a manhole drain. The tags width=*, material=* and colour=* can be used in a similar manner to a manhole drain.
