<div class="moz-cite-prefix">So a water tank with drinking water
cannot be tagged as drinking water because there is no local
access. Fine. <br>
</div>
<div class="moz-cite-prefix">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 class="moz-cite-prefix">Or a sub tag water=drinking water... <br>

<div dir="ltr">Hi Martin,
<div><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><br>
</div>
<div>Best regards,</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><br>
</div>
<div><a

</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>
