I'm glad I'm not alone in stubbornly avoiding the troll-tagging of 
tailing ponds and pig lagoons as natural=water. I'm fine with putting 
most reservoirs under natural=water, but this tag doesn't have to hold a 
monopoly on bodies of liquid. After all, clorinated pool water is mostly 
water, but we use leisure=swimming_pool as has been mentioned. A marsh 
is mostly covered by naturally collecting water, but there's 
natural=wetland and a whole wetland=* tagging scheme for that.


Most paper maps I've come across have treated bodies of water as 
distinct from bodies of other liquids, if they show the latter at all. 
For example, the USGS topographic maps cited earlier in this thread make 
no distinction between natural lakes and dammed reservoirs, but tailing 
ponds have completely different symbology. [1] If a renderer were 
unprepared to give special treatment to tailing ponds, I personally 
think it would be better for the renderer to omit them than to render 
them as bodies of water. That might require an altogether different 
primary tag like man_made=reservoir, since it's so common to render 
landuse=reservoir just like natural=water.


landuse=reservoir is an unintuitive tag for water-filled reservoirs, 
anyways. The pedant in me wants to double-map a reservoir as two areas: 
a landuse=reservoir area for the land underneath and a coincident, 
connected natural=water area for the H2O above it. But people complain 
about connecting landuse areas to other features, so I'll have to wait 
until April Fool's Day. ;-)

landuse=basin seems inappropriate for many wastewater  treatment plants.
It may be appropriate for plants which use constructed wetlands, but the
plants
that have aerators, clarifiers, digesters, etc. don't have anything that
could be
called a basin but do have large, mappable objects (the circular profiles
are
a good clue from aerlial imagery that a wastewater plant is there).  See
https://upload.wikimedia.org/wikipedia/commons/5/54/ESQUEMPEQUE-EN.jpg

There are also farm slurry pits, which handle animal faeces but do not
attempt to purify water.  https://en.wikipedia.org/wiki/Slurry_pit

I'm not entirely happy with natural=water being applied to either sewage
treatment or slurry.  Neither are natural and neither store water.

Re: [Tagging] Tagging sewage treatment basins

[Joseph Eisenberg]

The tag water_works=* is great for use with man_made=water_works - but
that's for treating water before it is used, not for treatment of sewage,
normally: "water works is a place where drinking water is found and applied
to the local waterpipes network."

But there is also
https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dwastewater_plant -
man_made=wastewater_plant so perhaps the key wastewater_plant=* would be
appropriate, e.g.: landuse=basin + content=sewage
+ wastewater_plant=decanter for your example?

I note that the page suggest using "water=wastewater" in this case instead
of water=basin or water=reservoir:
https://wiki.openstreetmap.org/wiki/Tag:water%3Dwastewater - "A
clarifier/settling basin of a wastewater treatment plant" - used >32,000

We can map the surface area, but knowing the average depth or maximum depth

Re: [Tagging] Tagging sewage treatment basins

[Brian M. Sperlongano]

With respect to basins, my understanding is that some of these have water
in them all of the time, some of them have water some of the time, and then
there are some that are almost always dry, but become wet only rarely when
they are needed (e.g. for stormwater handling)

Mappers have used BOTH landuse=basin tag as well as natural=water +
water=basin.  Both methods are documented in the wiki (parallel tagging
scheme).

Should basins be tagged as landuse, water, or both?  Or does it depend on
the type of basin?

You may have opendata, knowledge or sometimes measurements.
Many tags are already available but not used at the proper extent.
For example, if we add capactiy (in cubic meters) on a waste water basin,
we could do the same for man_made=covered_reservoir or even water=reservoir
(if information is available somewhere)
Look at this water tower hunting website giving many details from ground

That's right, usage=* corresponds to large familiy of activities and more
specific tagging would be more suitable to describe precise purpose of a
particular basin
reservoir_type and basin looks like to refer to reservoir/basin purpose but
mixes may concepts that may collide (irrigation is a water_storage as well)
Only some values would match with usage=* ones: usage=irrigation is used
12k vs reservoir_type=irrigation 50

Waste water processing could be described with less used water_works=*
man_made=basin (An artifical structure designed to store some fluid, you
find basins for storm/rain/radioactive water, sewage, oil, ...)
content=sewage (Let's put waste water inside)
usage=industrial (It's part of an industrial process)
water_works=decanter (It's an actual decanter)
capacity=

I'd find great to use water=* with content=water, substance=water or
natural=water only.

That's my 2 cents, let's refine it

All the best

Re: [Tagging] Tagging sewage treatment basins

[Joseph Eisenberg]

Re: "volume, elevation and sometimes particular usage"

I don't think mappers can know the maximum volume or capacity of a water
reservoir or water basin, unless it is written on a public sign somewhere?
We can map the surface area, but knowing the average depth or maximum depth
is quite difficult, especially when it is not uniform. However for
man_made=reservoir_covered and =storage_tank we have capacity=* (in cubic
meters?) and content=water/sewage/etc.

It is possible to use ele=* for the elevation of the surface of the water
if a mapper has a very good GPS or finds this info on a sign, but this
information is also widely available from digital elevation models.

The usage is not often tagged yet, since this might be hard for a mapper to
know.

Currently for landuse=reservoir and water=reservoir this is some use of
reservoir_type= - https://wiki.openstreetmap.org/wiki/Key:reservoir_type -
with values of water_storage, sewage, tailings, evaporator, tank, salt_pan,
wastewater, slurry, irrigation, aquicultura, cooling, etc - though only the
first 4 are at all common.

basin=* is used with landuse=basin or water=basin to describe the form and
function of the basin:

   - basin =infiltration
    - An
infiltration
   basin  catches
   storm water and allows it to seep into an aquifer
   .
   - basin =detention
    - A detention
   basin  catches storm
   water and allows it to drain slowly into natural waterways.
   - basin =retention
    - A retention
   basin  catches storm
   water and retains it, forming an artificial pond.


And note that salt ponds (used to evaporate salt from sea-water) are tagged
as landuse =salt_pond

Pools for swimming are leisure
=swimming_pool


I don't see many combinations with usage=* or another tag that might
describe how the reservoir or basin is used, so perhaps this could be
proposed?

Have a look to Storage chapter in this page (probably lacks many thing,

There are at least 5 ways to tag features involved in (potable) water
storage
What if I'm only interested to find "water storage places" with their
volume, elevation and sometimes particular usage?
Waste water retention basins are a supplementary situation like we could
find dozens of them.
Where will this end?

All discussed features share the "water body" concept (or more generic
fluid-body with substance=water) inside very different structures with even
different purposes.
Why don't we look to describe a generic water body, with a volume,
elevation and usage prior to list every single feature that stores/retain
water?

This said, it's fine to have many different tags to describe very different
structures (building=*, man_made=*, natural=*...)
As such structures tagging should be separated from the water body they
contain, an uniformed semantic for water bodies would make OSM a yet cooler
place than it already is

All the best

Re: [Tagging] Tagging sewage treatment basins

[Brian M. Sperlongano]

I knew them as sewage treatment ponds, but apparently there's a name for
them:

https://en.m.wikipedia.org/wiki/Waste_stabilization_pond

I feel like this a separate class of object that deserves its own tag,
either within or separate from natural=water, or perhaps even subclassed as
water=basin+basin=waste?

[Tagging] Tagging sewage treatment basins

[Joseph Eisenberg]

How should sewage treatment facilities be tagged, then?

Isn't sewage 99% water?

I think that most sewage treatment facilities in the USA include open
settling basins and I would use landuse=basin or water=basin +
natural=water for these: https://www.openstreetmap.org/way/420075503
