The Council is pretty efficient at clearing this. But of course, clearing it (regularly) just encourages some people to believe that dumping here (or anywhere else on the public streets) is somehow acceptable. It is not.
If there is some reasonable chance of identifying the perpetrators, either by witnessing details of persons or vehicles ‘in the act’, or by information contained in items dumped, the Council will consider prosecuting. When convictions are secured, they will seek maximum publicity to deter others. If any SE23 members want to email me (address from Council website) with such evidence, I’m happy to pass it on if they wish to remain anonymous.
