It was a white transit van. I have a photo of the offending vehicle which I will send to United Utilities. I did phone 101, the non emergeancy police line, but they said fly tipping was not their responsibility it was the Environment Agency's. I thought law breaking was always the police's rsponsibility.
Just to keep people informed I have signed a statement regarding the fly tipping and the van owner will be invited in to see the council. The gentleman at the council who I spoke too seems to think it is an open and shut case and that the van owner will suffer quite severe financial retribution as a result. I would encourage anybody else who sees anybody fly tipping to report it
