That's not the topic of this thread.
Title is, 'Sewage Polluters should worry'. Believe it or not, they do. It people who have no idea about the way the system operates, but think screaming from the rooftops about things they have very little understanding of, will solve the issue overnight.
200 hours is 8 and a bit days, The entire Country saw unprecedented continuous rainfall for many days, and this water has to go somewhere. Where would you propose the Water Companies put it all? And again, it is not 'Raw Sewage' it is
heavily diluted with rainwater, and is probably less environmentally unfriendly than the runoff from roads, car parks etc, containing oils, cigarette ends, and whatever other detritus the Human Race has dropped wherever they see fit.
Those who work in the water Industry are as keen as the rest of the Population to sort the issue out, but whilst we're seeing large population increases, climate change and the various other factors affecting the sewerage network across the Country, there is no magic solution. To capture and treat every last drop finding its way into the Nations Sewers would require half the Country to be covered in Storm Tanks, and then we'd still need to treat what we'd collected....
Storm Overflows cannot be selective on what gets discharged unfortunately, perhaps if the General Population did their bit and stopped using the WC and drainage system in general as a dustbin, then some of the issue would be negated.
As I have said previously, pulling the Water Industry back into Public Ownership will solve absolutely nothing. I will ask again, How do you think it will solve the issue? Finding soundbites is easy. Finding answers not so.
