South West Water has been ordered to pay more than £40,000 in fines and costs for polluting a watercourse in Devon.
Exeter Crown Court was told a combination of plant breakdown and poor management led to the contamination of Woodbury’s Polly Brook with poor quality sewage in August 2013.
This led to the death of a number of fish, according to the Environment Agency.
South West Water admitted to two charges – allowing untreated sewage to pollute the stream and failing to notify the Environment Agency of the problems with the treatment process.
The company said: “We apologise for an incident in which the final effluent at Woodbury Sewage Treatment Works failed to meet the appropriate quality standards for a short time in August 2013.
“Although there was a short-term effect on the Polly Brook, it was localised and the stream quickly recovered. The equipment was replaced and operators have since received refresher training on incident reporting and management.”
