On 31 March 2022, the Environment Agency issued the latest set of data for sewage and storm water discharges.
The data show that there has been no improvement in the number of discharges from CSO (Combined Sewer [or Storm] Overflows) into our rivers. Theoretically, these data are more reliable than previous versions since more CSOs now have Event Duration Monitors (EDM) which, when working, are designed to measure how much and for how long the CSO discharges into our rivers and coastlines. This makes it all the more worrying that there’s no improvement in pollution of our rivers (and coastal waters), a view shared by the Environment Agency and other NGOs.
The EA say:
While we welcome recent commitments from water companies to reduce their use of storm overflows, the data published today shows there is no room for complacency. They have a very long way to go.
The various water quality campaigning groups have expressed their views rather more strongly. For example, the Angling Trust says:
Water companies are continuing to abuse our rivers with very little change in the amount of times they discharged sewage from storm overflows in the past 12 months.
