We already know he has a breathing problems, maybe he also has other health issues that require him to drink only filtered water. And if you want to make the argument that he's a cyborg, that only supports my argument, as mechanical devices are often sensitive to dirt particles, and other environmental interference.
As for doing it himself, he has a tendency to choke people who piss him off, both of his Death Stars have been blown to hell, he betrayed the Jedi Order, killed his wife, and his children are the leaders of the Rebellion. Who in God's name could he find in the Empire who wouldn't want to slip something in his water, if only to save their own asses from him?
