Water is almost never bad for you, except in very large amounts.
You absolutely need to drink more water/tea than usual while fasting and this is pretty much recommended at least by most professionals is the survival sector (probably by more, but in this case I know for sure). Especially if you need to get things done; while having no food drinking is even more important.
