Thames Water to repair sewer network in Watford following flooding
What happened
Flooding occurred on Cardiff Road in Watford on October 22, 2026, following rainfall. A spokesperson for Thames Water stated that an investigation identified a blockage within the local sewer network that had self-cleared. Thames Water engineers will return to carry out further investigations, undertake a sewer clean, and complete repairs to a damaged chamber.
Why it matters
The affected pipe is an existing Thames Water asset, and the company confirmed that the damage was not caused by the nearby Watford Riverwell development. Thames Water is now undertaking a full inspection and repairs of its local infrastructure.
