The joint maintenance project between South West Water and Wessex Water on Wimbleball dam is complete.

The work involved injecting grout into the bedrock to block fissures and prevent water ingress.

The project has been a success, with leakage through the dam reduced to historically low levels not seen since it was constructed.

This will help ensure the integrity of this vital and iconic structure for decades to come.

We would like to thank everyone for their patience during the works.
