That does not stipulate if it is drinking water. <br>

<div>So a water tank with drinking water cannot be tagged as
drinking water because there is no local access. Fine. <br>
</div>
<div>Then it is only tagged as a tank with contents=water,
or should there be yet another value for it
contents=drinking_water?</div>
<div>Or a sub tag water=drinking water... <br>

</div>
<div>There are a couple of issues I see with
drinking_water=yes not having a concept of access. <br>
</div>
<div><br>
</div>
<div>1. Where is the observability ? How can I know if
a water tank has drinking quality water or just
agriculture quality water ? </div>
<div>From the wiki : </div>
<div>"<span style="background-color:rgb(249,249,249);font-family:sans-serif;font-size:13.3px">One
can assume that the water is pure when many people
drink it every day." </span></div>
<div><span style="background-color:rgb(249,249,249);font-family:sans-serif;font-size:13.3px">This
is hard to assume, and one would never know if there
is water ...</span></div>
<div><br>
</div>
<div>2. But there is an even bigger issue --- and I
will admit that I am biased because of the European
Water Project's use case. </div>
<div>For a map feature to be useful, it should have
universality. Ie. if one maps restaurants with
toilets, at least customers should have access ... </div>
<div>Someone who goes to the OSM way where there is a
water tank, even with a wallet full of cash, will die
of thirst before getting a drink.</div>
<div>It's similar to toilet=yes ... A restaurant with
a toilet for employees only, probably shouldn't have
the tag. </div>
<div>Yes, there is an access tag, but in most cases
access is implied. </div>
<div><br>
</div>
<div>drinking_water = yes, seems to come with access in
99% of the 61,300 nodes and the large majority of the
8,178 ways. </div>

<div>I have noticed that the the key
drinking_water = yes for ways is sometimes
used in a manner not described in the
wiki.</div>

<div>The issue has to do with ways which
might store drinking water which is not
actually directly accessible. I think
this tag should be for accessible water. </div>

<div>I don't read from the wiki description that the
drinking water must be directly accessible. It
depends on the context feature. <br>
</div>
