Our California Plumbing Code, based on the 2006 Uniform Plumbing Code, requires drinking fountains in certain locations per Table 4-1. Per footnote 12 on that same table: "where food is consumed indoors, water stations may be substituted for drinking fountains." It goes on to describe that larger office buildings may need drinking fountains for employee use, but in the context of the table 4-1, there may still be interpretive room on this issue and a water station might still meet the requirement in lieu of a drinking fountain.
So in theory, if your applicant says they intend to consume food indoors (for example, and employee break room), then a water station may be a viable alternative, at least here in California.
This leads to the next question: what is a "water station"? We believe it is a facility where a container can be filled with water for drinking purposes. On the old code chat bulletin board, various people offered that this could be a domestic water sink with paper cups nearby, or bottled water, etc.
The high/low concept for drinking fountains has to do with bending over to get your mouth near the stream of water. At a water station, you don't bring your mouth to the water - - you bring the water to your mouth (via a container), so bending over, hi/low provisions are not an issue.
I personally don't think that supplying drinking water in every facility is a civil rights issue. I think it is up to the code to state when it is required. However, when drinking water is supplied, then reasonable accomodation for everyone to have access to that water IS a civil rights issue. We also believe that under the concept of equivalent facilitation in our building code, a "water station" would also need to be accessible, using forward or side reach ranges for access to controls and dispensers.
It is possible that a water cooler could be made accessible. for example, I used a water cooler last night where the cold water valve was a push-down lever, operated by very light pressure. This could be operated without grasping or pinching, etc. A container could be placed on the drain grate under the spigot, so the user would not have to hold the cup while the water is coming out.
This same water cooler had a hot-water option that had a child-proof safety latch that would NOT be considered accessible.
