Rain water (rain water), which in the drains. As rain from the atmosphere of dust, soot, pollen and gas dissolves and roofs, paved areas and agricultural existing dust and pollutants are swimming with them, can precipitate outflows sometimes can include very harmful contents and must be treated. It therefore differs between active rainwater, which rain drainage ponds or in sewage treatment plants must be derived and not active rainwater, which in local waters or on the spot can be trickles away.

Here are dirt and rain water together in a pipeline.
