Like I said earlier, there wasn't any monitoring equipment so it wasn't like you say that the sensors weren't switched on, there simply wasn't any and it was down to Joe Public to report it. Now, there is monitoring equipment, the reported spills have increased which is good and now the water companies have to do something about it and I can assure you they will be doing it in the next AMP 2025 to 2030, but as always the bills will increase to cover the expenditure.
Putting politics aside this has always happened under all Governments since privatisation and also while being a member of the EU.
If you think things are bad now then look back and you will see that our rivers and the sea are in a healthier position now than they were in the 60"s when lots of inner city rivers were dumping grounds for industry, agriculture, tipping and the combined sewer overflows and they were essentially dead. There has been a lot of good restoring the environment and the next phase is sorting the CSO"s.
