Southern Water has apologised for the incident.

Its spokesman said: “We are sorry that a failure at our Wastewater Treatment Works on the 4 August led to a small release of screened wastewater into the Harbour.

“We take these cases very seriously and carried out a thorough investigation while working with the Environment Agency.

“While the impact to public health was very low, no amount of pollution is acceptable to us and we are working hard to reduce and eventually stop all incidents.”
