<p>The invention relates to a method for purification of rain drainage water, in particular, the run-off from roads, whereby the volumetric flow of the rainwater, during adequate precipitation, is divided into an early flow first partial stream and a subsequent partial stream, whereby the predominant portion of the first stream of rain drainage water is run into at least one collector chamber, with a good hydraulic separation from the subsequent partial flow, both partial flows are introduced into a purification and at least the partial collected flow is separated from contaminants in a purification method of greater separative capacity than a purely gravitational separation.</p> |
