I agree. This is why i proposed man_made=basin|tank in a later message.

Just because it's in use doesn't mean it makes sense, does it? See
landuse=basin.

You mean wastewater=clarifier|digester? I think so.

landuse for tagging features is not a good fit, I prefer man_made for these, as 
it fits better with the general scheme of tags

When you look at storage_tanks
https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dstorage_tank, there are
actually sub-tags for
content =sewage & content
=wastewater, a so it would
seem to be OK to use that?

These could also be used with Clifford's possible wastewater= key?

You should visit the other side of the state, then.  Virtually every
small town here has a group of two to six settling ponds, usually on the
downwind side.

Sorry, my mistake, i didn't think of tanks. The wastewater plants i've
mapped so far have concrete lined depressions like those on these
images:

I think it's okay to call them basins, isn't it?

You're right, basins aren't land uses.

What about man_made=basin and man_made=tank then? (I know that there
is man_made=storage_tank, but these tanks are for treating waste
water, not for storing them.) These tags could also be used for basins
and tanks that serve other purposes, for example slurry basins or
tanks.

There are some wastewater treatment facilities that use settling basins.
The ones I've mapped all use more advanced technology. Where I have heard
of settling basins is those used by large farm operations. The one that
comes to mind is during the flooding in the US Southeast where pig farmers
settling basins were covered by flood waters which resulted in tons of
waste flowing into the area.

If the wastewater plant used settling basins then they should be mapped as
such. But as I said, all of the plants I've seen use clarifiers and
digesters.

It has the disadvantage that it doesn't make sense.  At least not to me, as
a native speaker of
British English (which is the normal language for defining OSM tags) and as
somebody who
doesn't work in sanitation.  Maybe a British sanitation engineer would use
basin or a non-British
speaker would use basin but I most definitely would not.

Firstly, I don't think of a settling tank or clarifier as a basin.  A
porcelain object for washing hands
in a bathroom is a basin and a geological depression in which water
collects is a basin, and a
man-made depression for holding water might be a basin but a clarifier
isn't.  I can see the
commonalities in all of those but a clarifier just isn't a basin.  Other
than bathroom porcelain,
a basin requires a depression in the ground.

Secondly, if you're going to apply landuse to a man-mad object rather than
to an area of ground
that holds a collection of man-made objects then instead of building=house
we should have
landuse=house.  We don't do things that way.

Another idea i see is to extend the current tagging scheme with
landuse=basin (+ content=sewage) by creating new basin=* values
basin=clarifier and basin=digester. This would have the advantage that
no retagging is required and people that want to map the basins but
don't know their function can still map them.

Does sound good.

Would you also change the main  man_made=wastewater_plant listing?

Maybe wastewater=plant / facility?

Hi

That's a good idea, other components of wastewater treatement plants should
be mapped the same way
Nevertheless, man_made isn't appropriate for that.

wastewater=* or at least water=* should be used for such values, shouldn't
you?

All the best

[Tagging] Wastewater Plants

[Clifford Snow]

I'd like to expand tagging of wastewater treatment plants by adding in
clarifiers and digesters to the man_made=wastewater_plant wiki page.

This came about as I was editing an area with a wastewater treatment
facility. I didn't know what the various parts of the facility were
called.  A friend who works in GIS for the counties wastewater division
helped me with the terminology for these objects.

The two objects are
1. Clarifiers https://www.dropbox.com/s/k87y9sf144xxylv/clarifier.png?dl=0
2. Digesters https://www.dropbox.com/s/q8jxmgvs8heb314/digester.png?dl=0

According to Wikipedia, clarifiers are settlement tanks that continuously
remove sediment from the wastewater. [1]

Digesters use a process called anaerobic digestion is used to breakdown
sewage sludge. [2] since anaerobic digester is used in other processes, I'd
like to keep it simple and just call them digesters.

For tagging, I'd to suggest the two tags.
man_made=clarifier (used 28 times)
man_made=digester (anaerobic used 3 times, including one misspelling)


I'm not sure if clarifier and digester are what the British call them, if
someone knows, please let me know.
