I'm thinking a water-oxygen drip system might do the trick. Have a gravity-fed "maze" filled with lots of oxygen, and drip water in from the top. It should have the germs die by the time it gets to the bottom. I have noticed that thin pools of water dissipate their germs fairly quickly if there is oxygen present.
