I went up river looking for the problem and found it along side Waters Meetings Road at a Combined Sewer Outlet (CSO) that was discharging raw sewage into the river.
Not a pretty site. (tried to put a video of this on the blog, did not work)
Did not bother fishing, but waited to see if any action was forthcoming and to show anybody who turned up where the CSO was and how the get to it. I waited in vane. Will check tomorrow.
Got the video to work at last.Wednesday 16th Lunch time, went to see it had stopped discharging, but it was just the same as yesterday. Phoned the Environment Agency again.
Friday 18th Went down to see if sorted glad to say that it was though it still looks nasty.
