How to map a processing basin in a wastewater_plant? Validator and presets are not very helpful.

[mdk]

In the wiki I found the following taggings:

• landuse=reservoir & reservoir_type=sewage (​http://wiki.openstreetmap.org/wiki/DE:How_to_map_a)
• natural=water & water=wastewater ( & optional landuse=basin) (​http://wiki.openstreetmap.org/wiki/Key:water)
• landuse=reservoir or natural=water & water=wastewater (​http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dwastewater_plant)
• natural=water & water=wastewater (​http://wiki.openstreetmap.org/wiki/DE:Tag:man_made%3Dwastewater_plant)
• landuse=reservoir is deprecated (​http://wiki.openstreetmap.org/wiki/DE:Tag:landuse%3Dreservoir)
• landuse=reservoir is not deprecated (​http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dreservoir)

The validator complain about water=wastewater ("Value 'wastewater' for key 'water' not in preset").
Also the validator knows nothing about the reservoir_type key ("Key 'reservoir_type' not in preset").
But the validator has a rule for "reservoir_type without landuse=reservoir or water=reservoir".

I think validator and presets should support at least one schema (old or new) or both (if there is no consensus). In the wild there is a complete mess. Today I saw:

• natural=water & water=reservoir
• man_made=waste_water & natural=water & water=reservoir
• man_made=waste_water
• man_made=waste_water & water=reservoir
• man_made=water_tower & water=reservoir
• man_made=water_works
• man_made=wastewater_plant

only for the basins where the water is processed in a single wastewater_plant! :-)

Can you give a link to this wastewater plant?

Replying to Klumbumbus:

in a single wastewater_plant!

Can you give a link to this wastewater plant?

It's the MASERU WASTEWATER PROJECT in Lesotho.
It's splitted in two parts: ​https://www.openstreetmap.org/way/394187986 and the big ​https://www.openstreetmap.org/way/394187986
But I have (hopefully) fixed them :-)

Hm, you posted the same link twice!?

Sorry, the second link is ​https://www.openstreetmap.org/way/432813491

In 10860/josm:

fix #13194 - update water, basin and reservoir presets; fix #13391 - remove autofix for wood=deciduous
