It is a rudimentary lesson of statistics that correlation does not necessarily equal causation. Otherwise, Thames Water customers might reasonably conclude that the higher their bills rise, the more sewage the company pumps into London’s rivers.
The Evening Standard has today revealed that sewage flowed into the capital’s waterways for nearly 10,000 hours last year, up from almost 7,000 hours reported in 2022. It comes as Thames Water customers have been forced to swallow hikes averaging 12.1 per cent this week, with the firm refusing to rule out future increases as it grapples with debt and interest payments.
