#TIP: we don't use descriptive names in OSM. Just tag the feature. For example, building=yes or if you know the type of building you can tag it as building=house.  For the water treatment feature I'm guessing it is a clarifier which is tagged as man_made=clarifier. See https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dclarifier. I'll send you more info on OSM in a message.
