Water restored after burst main disrupted schools and affected thousands

## Verified facts

- The supplied Press Association report says Thames Water reported that water supplies had been restored or were being restored after a large burst main in West Molesey, Surrey. - Thames Water said the burst initially affected up to 15,000 properties, with the reported number later falling to 6,000. The company said some customers could experience low pressure and that engineers were continuing a permanent repair. - The outage affected multiple postcode areas across parts of Surrey and south London. Several schools and nurseries, including Esher Sixth Form College, Holy Cross School, Thames Ditton Infant School and Long Ditton Infant and Nursery School, said they had closed because of the water-supply problem. - Monica Harding, MP for Esher and Walton, told the Press Association that she wanted an urgent response and said the cause should be established once supplies had returned. She also expressed concern that underinvestment and regulation might be contributing to incidents of this kind. - Paul Kohler, MP for Wimbledon, said he had contacted Thames Water about reports of an outage affecting Wimbledon, New Malden, Raynes Park and Morden. Liberal Democrat leader Sir Ed Davey criticised Thames Water and cited figures about leakage and debt servicing; those figures are presented in the report as his claims. - Thames Water said a bottled-water station would be opened for customers who needed it. The report also describes public criticism on X and a straw poll at the Labour Party conference in which 99 of 100 votes favoured public ownership of Thames Water.

## Interpretation

The immediate disruption appears to have been caused by the burst main, with the reported consequences extending beyond households to schools and nurseries. The episode also became a vehicle for broader criticism of Thames Water’s infrastructure, finances and ownership, particularly through comments from elected representatives, campaigners and members of the public.

The restoration announcement indicates that the immediate service failure was easing, but the continuing permanent repair and warning about low pressure mean that full normalisation was not necessarily complete at the time of the report. The incident’s wider significance remains connected to the competing political claims about investment, regulation and public ownership rather than being established solely by the outage itself.

## Uncertainty and limitations

- The restoration status is based on Thames Water’s statement as reported by the Press Association; the supplied evidence does not independently verify that all affected customers had regained normal service. - The number affected changed from up to 15,000 properties to 6,000 in Thames Water’s updates, and the evidence does not explain the reason for the change. - The report includes Monica Harding’s understanding that water had been leaking at 750 litres per second, but the supplied evidence does not independently confirm that figure. - Claims about decades of underinvestment, poor regulation, leakage, debt servicing and the company’s overall performance are attributed to politicians or campaigners and should not be treated as independently established by this evidence. - The evidence does not establish whether the burst main resulted from underinvestment, regulation, or another cause.
