[souffle]

Have you seen her bottle chewing at all? This looks like she is bottle chewing and the water is going in the pouches then seeping out again. I would remove the water bottle right away then give her a small bowl for water and see if this stops. They can get obsessed with the spout and shove it right in the pouch and damage the lining which should be dry.
Hamsters can also drool of they get overgrown teeth or maloccluded teeth or pouch or tooth abscesses. The saliva causes soreness and redness and she doesn't currently look to have that. I think she's bottle chewing and it's making you think she's drinking a lot
