Water regulator Ofwat has criticised Anglian Water, Northumbrian Water, United Utilities, Southern Water, Severn Trent Water, Yorkshire Water and Veolia Central for not adequately maintaining their underground infrastructure.
The regulator yesterday published its Summary of Performance for 2010/11, and said these seven companies need to do more to maintain their underground infrastructure to a satisfactory standard. Ofwat said Anglian Water, United Utilities, Northumbrian Water and Southern Water had scored particularly badly on underground sewerage infrastructure maintenance. The companies named must now restore stable serviceability or be forced by Ofwat to return money to customers at the next price review, in 2014.
Ofwat also said six companies — Anglian Water, Dŵr Cymru Welsh Water, Northumbrian Water, Southern Water, Severn Trent Water and Yorkshire Water — had failed to meet their leakage targets in 2010/2011. “We will examine the progress of all six companies until they meet their targets,” Ofwat said. “If they do not, we can take further action.”
Severn Trent Water was singled out a third time in Ofwat’s report for being the one water company with a particularly high number of supply interruptions to customers. Severn Trent Water said it has already made “dramatic improvements” in the areas of concern highlighted by Ofwat. “On supply interruptions … we have focused our efforts into a major programme of improvements and this is on track to deliver significant reductions to these numbers,” the company said.
