Nope, it don't go in the sewerage system. Thats a no, no. Stuffs up the treatment process as it dilutes the "food" for them little microbes too much and overloads the system. Putting stormwater into the sewers can lead to a heavy fine too.
But I agree there should be more capture and storage of street run off. The drawback is not the solids in the flow its the contaminants from petroleum products off the roads and other hard to remove substances. Treatment to usable standard is actually more difficult than sewage.
