A water company has been fined almost £8m for a series of pollution-related offences over six years.

South West Water previously entered guilty pleas at Plymouth Magistrates’ Court after an investigation by the Environment Agency into incidents between 2015 and 2021 in Bodmin, Harlyn, Playing Place, and Polperro in Cornwall, and Plymouth in Devon.

Sentencing, Judge Jo Matson described the pollution “horrendous” and “very significant”.

The water company said in a statement after sentencing: “We apologise for what happened in the past.”

Of the 18 charges, 17 were for illegal discharge activities including sewage discharges and one is for failing to take reasonable remedial measures following a failure at a sewage pumping station. The firm was fined £7,867,733.

South West Water said the case related to “historic matters between 2015 and 2021” and the majority of spills involved “the use of overflows in storm conditions”.

“We’re investing £760m to tackle storm overflows and have reduced spills by 17% in the last year alone, with spill duration down by 25%,” the company said.

It added “significant improvements” had been made at the sites where pollution occurred.

“We remain focused on the future as we deliver record levels of investment to achieve cleaner rivers and seas across the South West by 2040, a decade ahead of national targets,” it said.
