South West Water has been ordered to pay £205,000 in fines and costs for discharging sewage into the Fal estuary in Cornwall. The case was brought by the Environment Agency.

On 26 August 2013 untreated sewage overflowed from the water company’s Newham sewage treatment works near Truro into the Fal, an internationally important shellfishery, Site of Special Scientific Interest (SSSI) and Special Area of Conservation (SAC).

The illegal spill occurred after a piece of redundant grating fell and partially blocked an inlet at the works, causing sewage to back up and overflow into the estuary via a storm storage outfall. The spill continued for about 9.5 hours, during which time enough sewage escaped to fill 4,563 bath tubs (730,000 litres).

The discharge occurred close to mussel and oyster beds at Malpas and Grimes Bar. As a precaution, these shellfisheries were temporarily closed by Cornwall Port Health Authority because of the possible risk of contamination by harmful viruses and bacteria such as Norovirus and e.coli.

The decision to close the shellfish beds was taken just before the start of the commercial harvesting season (1 October). Although most harvesting is done during the commercial season, there is a risk small quantities of shellfish may be hand-picked by individuals outside of this time and there would have been a potential risk to those consumers.

Sewage at the Newham treatment works normally undergoes a high level of treatment (tertiary) including ultra violet (UV) that kills bacteria and disinfects effluent. An UV disinfection system is required at this site because of the Fal estuary’s designation as a shellfishery.

The sewage discharged over a bank holiday on 26 August was settled and screened, but otherwise untreated and occurred outside of a storm event. This would have resulted in a significant increase in levels of bacteria in parts of the Fal estuary and meant the treatment works was in breach of its Environment Agency permit.

Mark Pilcher, team leader for the Environment Agency in west Cornwall, said:

It is essential large sewage works bordering estuaries with conservation designations and also containing shellfish beds are operated and inspected to a high standard to prevent unpermitted sewage spills posing risks to public health and the environment.

In this case an inspection programme or removal of a redundant grating structure would have removed the risk of this grating falling into the sewage works and blocking it leading to the spill of sewage.

South West Water Limited was fined £185,000 plus £20,000 costs after pleading guilty to 2 offences under the Environmental Permitting Regulations 2010 including, on 26 August 2013, causing pollution of the Fal estuary through the illegal discharge of sewage and failing to maintain a saline tank valve at its Newham sewage treatment works. The water company was fined £175,000 for the first offence and £10,000 for the second. The case was heard at Truro Crown Court on 15 February 2017.

Interserve Construction Limited (ICL) has been fined £54,000 with £5,955 costs after admitting a single incident of discharging silt-laden water into a tributary of the River Rother in Burwash, East Sussex on 1 October 2014.

ICL was contracted to South East Water over an 18-month period at the Crowhurst Bridge Water Treatment Works to improve South East Water’s ability to manage water treatment. The Environment Agency discovered a brown discharge downstream of the Works after a member of the public reported the discoloured water to them.

Further investigations showed that the river was visibly but locally impacted on a temporary basis.

In mitigation it was stated that this was an isolated incident of 25 minutes duration, during an 18-month contract and that the company was of previous good character. There was no evidence that local wildlife was adversely affected.

David Willis, Environment Manager at the Environment Agency, said:

We take these incidents very seriously and do everything within our powers to safeguard the environment and people that may be affected.

With the 2017 elver season under way, the Environment Agency is reminding Somerset’s elver fishermen to stay the right side of the law.

Eels are an endangered species and recognised by the Convention on International Trade in Endangered Species (CITES) as in need of protection. Fishing for elvers is allowed in England and Wales, but under strict conditions to ensure stocks are not over-exploited.

The elver season runs from 15 February – 25 May inclusive and is largely limited to the Rivers Parrett and Tone. There are approximately 200 licenced elver fishermen in Somerset who must register with the Environment Agency at the start of the season.

Sustainable fishing includes the capture of elvers for re-stocking in countries across Northern Europe where eel stocks have declined and cannot be replenished naturally.

All elver fishing in Somerset is done with hand held nets known as ‘dip nets’. They are restricted in size to 1m long, 0.8m wide and 0.45m deep. Handle lengths should be no longer than 4m. Fishing from boats is prohibited and no other large nets or traps are allowed. As a further precaution, all nets must be tagged and fishermen have photographic ID.

Elvers are attracted to fresh water so to protect stocks, no fishing is permitted within 10m of any river obstruction, dam, inlet, outlet or fish pass that hinders the passage of elvers. A full list of rules can be found in the elver fishing bylaws.

Richard Dearnley for the Environment Agency said:

We recognise the majority of elver fishermen operate responsibly and respect the law. We work closely with the police in detecting illegal fishing and, where we have evidence, won’t hesitate to prosecute offenders.

Any illegal or suspicious activity can be reported to the Environment Agency or Crimestoppers. If you would like to report information on environmental crime anonymously, call 0800 555111.
