<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><br></div><div>Stuart </div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, 20 Feb 2020 at 19:33, Martin Koppenhoefer <<a href="mailto:dieterdreist@gmail.com">dieterdreist@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Am Do., 20.
