South West Water

South West Water is a private water company in England, regulated by Ofwat and the Environmental Agency. It’s one of 3 water companies in England that remain on the London Stock Exchange, meaning it has public shares and operates as a Private Limited Company. However, it still shares many of the same big overseas shareholders as the rest of England’s privatised water companies. Shareholders are primarily based in New York City, USA.

South West Water have kept up their legacy of continuously performing significantly below target. They once again received a poor ‘red‘ rating for the 12th year running for their Annual number of pollution incidents from sewerage assets – of which there were 108.

Their behaviour time and again is simply unacceptable. And there is little evidence to suggest South West Water are taking the necessary actions required to improve their performance to protect people or the planet.
