A text message system, telling surfers and beachgoers when Dorset's beaches have been hit by sewage, is being carried on through the winter.

The Beach Live alerts are triggered by significant overflows - with the summer trial showing Bournemouth and Poole saw the most in the South West.

It's run by Surfers Against Sewage, who say bigger waves and better wetsuit technology mean more people are in the water even when it's cold.
