    "grey water" has a specific meaning (waste water that isn't sewage
    and can be further used for e.g. irrigation).  If that's what you
    mean - great.  If you just mean water that you can't drink, then
    just use something that describes it, like "water".<br>
    <br>
    Although <a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/Key:substance">http://wiki.openstreetmap.org/wiki/Key:substance</a> says
    "water
    == fresh water for drinking purposes" that doesn't match the real
    world.  Mappers adding e.g. irrigation pipes aren't going to check
    the wiki; they'll just say "that's a water pipe", so data consumers
    can't assume that "substance=water"
    == "fresh water for drinking purposes".<br>
