To our slight surprise (because strange location, who is going to maintain this?) both water taps still worked fine & free of charge, and although one drain (I think: for toilet) was clogged, the other (=grey) was open & fine. Incidentally, you can also tap free water at the car park directly to the north of Lorenzago di Cadore (at the very back on the right, but without a screw thread for the Gardena connection, so only via buckets). There are also rain wells.
