Water and oil flowing out of drain

The drains in Cromer High Street are blocked and out of the drain by Kenilworth there is water and oil emptying out onto the road. There is a strong smell of diesel and you can see the pattern of oil in the water. I suspect there is a leaking oil tank somewhere and the oil is getting into the drainage system. As the drains empty directly into a stream this will cause an environmental issue. Also oil on the road may cause an accident.
