Welsh Water admits illegally spilling sewage for years
Welsh Water has admitted to illegally spilling untreated sewage at dozens of treatment plants for years.
One of their worst-performing plants is in Cardigan in west Wales.
The company has been spilling sewage there into an environmentally protected area rare dolphin habitat for at least a decade.
Welsh Water says it is working to tackle the problems.
Most of the UK has a combined sewerage system, meaning that both rainwater and wastewater – from toilets, bathrooms and kitchens – are carried in the same pipes. Usually, all the waste is carried to a sewage treatment works.
