you see if you were to put your hand near a water wheel you can feel a little suck and there are little water particles in the air so they suck them up and store them till they get bug enough then...
a turbine would be used instead of a water wheel because a turbine does not use as much energy and it uses the wind to generate it.
Both have blades or buckets.
they are treated with strong UV rays, then the good bacteria kills germs in it so it will be safe to drink.LOL :)
