Sewage was dumped in the River Taff for more than 9,500 hours last year. The data released by Welsh Water shows that the River Taff is the sixth-most-polluted river in Wales with an average of three sewage dumps every day in 2022.
Earlier this week we revealed the terrifying amount of sewage poured into rivers, lakes, and seas around the whole of Wales last year. The worst-affected river is the River Garw – between Blaengarw and Llangeinor – which had sewage dumped at just four sites for a total time of 16,134 hours.
There were 29 sites along the River Taff where sewage was dumped in 2022 with the worst location being at the Cynon Valley WwTW with a total time of 2,213 hours. The Tongwynlais CSO emptied sewage into the Taff for 2,013 hours across 106 dumps.
