What's wrong with the water? It's the first time you mention it here.
If the water can't be seen, it (most probably; see below) means VVIS hasn't run, the most common reason for that is a leak.
If the water doesn't work in general, make sure you've built it properly: only the top face should have the water texture, the rest must have nodraw, and the top face should be completely horizontal (or it won't render again)
