Can rabies transmission occur by ingesting rabies contaminated water?

Unlikely : Very unlikely so have rabies transmission by water. Exposure to rabies occurred from a break in skin caused by the teeth of a rabid animal or by contamination of scratches, abrasions, or mucous membranes with saliva or other potentially infectious material, such as neural tissue, from a rabid animal.

Possible but rare.: Per the CDC: "It’s possible for the rabies virus to be transmitted through water if an animal is drinking out of a water dish at the same time as another rabid animal or shortly after the rabid animal was drinking. The virus will not survive for long in water, but it will last long enough to possibly infect another animal."
