Privatised water companies discharged raw sewage into rivers and the sea around England and Wales for 3.6 million hours in 2023 – double the previous year’s total. For a sense of how bad the problem is today, check this map of the south-east of the UK which shows how much sewage water companies are dumping right now and for how long.
As a water researcher, I am happy to see water quality high on the political agenda but aggrieved that it is because of the sewage scandal that has engulfed the UK, and especially England and Wales, in the past couple of years.
Companies have discharged more raw sewage than they are legally allowed to and the Environment Agency, as responsible regulator in England, has been unable to monitor and control offenders as its environmental protection budget was halved between 2010 and 2020. Water firms have neglected to invest in new and enlarged wastewater treatment works for decades and so the ageing system is struggling to meet demand.
