Thames Water Reveals Spike in Sewage Spills
The UK’s biggest supplier, Thames Water, which has been battling to avert the prospect of a special administration amid a massive debt pile, has consistently argued that the regulator’s ruling on its request for an inflation-busting rise to charges could make it uninvestable.
Thames, and the wider industry, is due to learn next week what Ofwat will allow bills to rise by over the next five years.
Thames is seeking hikes of 59% over the period, setting it on collision course with the regulator, as it says the determination will either help it unlock crucial new investment in the business or force it towards a taxpayer rescue.
Thames, which said it had improved on many of its operational performance targets over the first six months of the year, blamed record rainfall for the big rise in storm overflow incidents.
Spills are measured on a calendar-year basis and rose to 17,564 between January and September 2024, compared with 12,428 in the same period the previous year, Thames said.
Its statement added: “2024 saw the wettest Spring since 1986, according to the Met Office, with over 30 cm of rain in England.
“Rain or groundwater getting into our sewers is often the main cause of storm overflows, known as spills. In some areas, our system has been designed to operate in this way, though the circumstances of a spill may or may not be permitted.”
Thames revealed a 7% rise in its debt pile to £15.8bn over the six month period.
That covered time before the company agreed a £3bn loan deal to keep it operating beyond mid-2025.
