I am with the 'drink the water and be damned brigade', never had any problems with drinking water when tenting, caravanning ot MH'ing. Do fill up my water bottle and bladder
Platypus, that is, not mine
when I am walking just because it is easy to wander over to the tap, making sure on the way that my boots are comfortable, than using the water in the tank, do the same with Jess's water too. washing her bowl out into the grey disposal place then filling it up with fresh from the tap
