Sewage continues to be released from Witney Sewage Treatment Works.

A tweet from the alert system this morning said the release, which started in the early hours of Christmas Day, could potentially continue until tomorrow.

The alerts, which are tweeted via @oxthamessewage, cover six sites and are posted by water company Thames Water, Oxford City Council and charities Thames 21 and The Rivers Trust.

Treatment works are only allowed to put sewage into waterways after wet weather and when they are close to capacity.
