Sennecé-lès-Mâcon's lavoir in rue Vrémontoise is one of two lavoirs which remain in the village. Weirdly, a sign in French alone says the water isn't drinkable, and another (in French, English and German) says bathing is prohibited: now who'd have imagined that? The griffon's head is quite a normal sign.
The second is on Chemin de la fontaine Pétouzan by the D103 and also contains the 'no bathing' sign. I don't notice an 'eau no potable' one, but then there's a drought on at the moment (I'll leave emoji out).
