Water companies fined record £XXm by regulator

Ofwat has found that the three companies failed to adequately invest in and maintain their networks, leading to repeated releases of raw sewage into the country’s waterways.

The regulator’s Chief Executive, David Black, said: “Ofwat has uncovered a catalogue of failure by Thames Water, Yorkshire Water and Northumbrian Water in how they ran their sewage works and this resulted in excessive spills from storm overflows.

“Our investigation has shown how they routinely released sewage into our rivers and seas, rather than ensuring that this only happens in exceptional circumstances as the law intends.”

Releasing raw sewage has the potential to significantly damage the environment and poses a risk to human health for those swimming in a river or sea where sewage is being discharged.

In December 2023 Ofwat notified the three companies of its provisional findings and they had the opportunity to provide any further evidence for consideration.

On Wednesday it proposed fines of £104m for Thames Water, £47m for Yorkshire Water and £17m for Northumbrian Water.

The BBC has contacted all three companies involved for comment.
