SOUTH West Water (SWW) has been fined more than £7.8 million in a case brought by the Environment Agency for environmental offences across Devon and Cornwall over a six-year period.

It is the largest ever fine imposed for environmental offences in the region.

Delivering her sentence, District Judge Matson said that “incidents of pollution will not be tolerated” and fined the water company £7,867,733 at Plymouth Magistrates’ Court on September 29.

The Judge repeatedly found that the company’s conduct amounted to reckless failures in management systems and response to known risks.

The company had pleaded guilty at earlier court hearings to 18 charges, 17 for illegal water discharge activities and one charge for failing to take reasonable remedial measures following failure at a pumping station.

The offences took place between January 2015 and July 2021 in six locations across Cornwall and Devon: Bodmin, Harlyn, Playing Place, Polperro and Plymouth.

The water company was ordered to pay £329,993 costs and £120 victim surcharge.

SWW previously pleaded guilty to six criminal charges relating to spills at Holywell Sewage Pumping Station. These will be considered at a later date to be determined.

Hundreds of sewage spills took place over six years at popular bathing spots and some of our most sensitive habitats.

The Judge quoted South West Water’s mantra that “one pollution is too many” and said that SWW need to make sure they carry their mantra forward, “to ensure that horrendous, very significant incidents of pollution such as these never happen again.”

On August 24, 2019, “untreated sewage gushed through the harbour wall on a bank holiday weekend” at Polperro Harbour. South West Water were fined £1.1 million for this single incident.

Despite alarms firing, SWW took 10 hours to attend the incident.

Across multiple sites, SWW failed to put in place and enforce systems of environmental management as could be reasonably expected.

On 231 occasions between January 2016 and July 2021, untreated sewage was discharged onto Harlyn beach, a location popular with locals and tourists.

At SWW’s sewage works near Bodmin, there were 336 illegal spills in the seven years to March 2020.

In another case, SWW failed to provide a permanent fix for a combined sewer that entered a small stream known as Budshead Creek in the Whitleigh area in Plymouth, despite multiple formal warnings from the Environment Agency over several years. This led to two pollution incidents in August and September 2020.

The Judge found that SWW knew the pipe was precarious and yet did nothing about it for years until it collapsed in 2020 and “raw sewage spilled into the watercourse”.

Despite pleading guilty, the Judge found that SWW, instead of being remorseful and accepting full responsibility for acts, have tried to minimise their role in the offending.

South West Water has 56 days to pay all penalties in full.

SWW was previously prosecuted in 2023 for 13 charges between July 2016 and August 2020, and was fined £2.15m.
