Plea to ban car washing in streets...

[KaraK [T]]

It doesn't just go through those holes on the side of the street which are linked with the sewers, it also flows through the gaps between the stones, and there excises permeable tarmac. Not often used though (from what I read).

Not every road is made out of tarmac, and even if it is, the sides still have tiny cracks water can flow through.

I disagree with disallowing washing your car on the street, but I see why they (want to) do so.
