Rainwater is pretty dirty from pollutants in the atmosphere and has a strong pH value in many cases depending upon location.

EDITED for spelling and added clarity.

It's not that dirty, but you do have to design for those concerns.

Acid rain can be buffered by adding seashells (lime) in the tank.

You can easily tip off the first N gallons of dirty rain (pollution, roof washing, etc) with a dead-end pipe with a dribble tube.
