Cornish charity claims sewage was discharged into our waters over 5,000 times in a year
Surfers Against Sewage have released a new report on the issue
Last updated 25th Nov 2021
A Cornish charity says water companies in England and Wales have issued more than 5,500 alerts of sewage being discharged into coastal waters in the last year.
St Agnes based Surfers Against Sewage has released a new report.
It claims one in six days of the official bathing season were rendered “unswimmable” due to sewage pollution near beaches and other popular coastal spots.
The campaign group said the problem of pollution from storm overflows, which put untreated sewage into the seas and rivers to stop drains overflowing, for example after heavy rain, was increasing.
The charity accesses data on notifications of sewage discharges by water companies and issues a real-time sewage alert through its “safer seas and rivers service” to warn swimmers, surfers, paddleboarders and kayakers of potential pollution.
Its annual water quality report said a total of 5,517 sewer overflow discharge notifications were issued by water companies over the 12-month period to the end of September, – an 87.6% increase on last year’s figure of 2,941.
Some 3,328 were issued during the summer bathing season, up on 2020’s figure of 1,195.
Some of the increase is due to more notifications and more locations provided by water firms, but Surfers Against Sewage also warned there was not a direct correlation between heavier rainfall and more discharges.
Southern Water scored worst for the total number of sewage overflow discharges, and for the average discharges per location and per 10,000 kilometres of sewage network, according to the report.
Surfers Against Sewage warned that with some water companies only providing information during the bathing season and data only available for coastal waters, the numbers are likely to be a conservative estimate for the number of times sewage is ending up in the seas and rivers.
The charity said all water companies had now agreed to provide notifications throughout the year – important as more than half (56%) of recreational visits to the coast occur outside the summer months.
With notifications kept “live” for 48 hours after they have occurred to allow pollution to disperse, some 6,656 swimming days were lost during the official bathing season alone across the hundreds of monitored sites, or 16% of all days.
Overall 11,034 swimming days were lost over the year as a result of
sewage pollution, 10% of the total from October 2020 – September 2021.
The charity also gathers health reports from water users, with 286 reports of sickness in the last year – an increase of 124 cases on the previous year.
Nearly a third (30%) of reports came within 48 hours of a sewage overflow discharge notification or a pollution risk forecast, issued by regulators to provide an indication of when there might be an increased risk of pollution.
The water quality report also highlighted the poor state of UK rivers.
As part of the charity’s data collection, citizen scientists conducted regular water sampling at eight locations where a river flows into the sea at, or close to, a designated bathing water.
The testing found six out of the eight sites monitored had elevated E.coli levels, showing overall poor quality results throughout the bathing season, Surfers Against Sewage said.
Hugo Tagholm, chief executive of Surfers Against Sewage, said: “The findings of our report are shocking and outrageous, but they are by no means unexpected.
“Time and time again, governments have claimed concern over the pollution of rivers and seas, but have so far failed to take concrete action to change the status quo.
“Loopholes in laws and systematically defunded regulators have left water companies to run amok.”
He added: “We need water companies to clean up their act and commit to a decade of change to ensure our rivers and coastlines are thriving with people and wildlife again.”
The report comes after the Environment Agency and Ofwat launched a major investigation after checks revealed that some water firms may be releasing unpermitted sewage into rivers and watercourses from treatment works.
A recent public backlash over raw sewage being dumped into rivers also forced the Government to include measures to tackle the problem in the Environment Act.
Dr Toby Willison, director of environment and corporate affairs at Southern Water, said: “We share the passion and commitment of Surfers Against Sewage’s to protect our precious coastal water and the 700 miles of coastline in our region.
“We know our performance has to improve and we are driving a step change in investment spending £2 billion to cut pollution incidents by 80% by 2025.
“Our new task force aims to cut storm overflows by 80% by 2030.”
A spokesperson for industry body Water UK said: “Water companies recognise the urgent need for action to protect and enhance our rivers and seas.
“Our recent 21st Century Rivers report sets out the key steps needed to achieve the radical changes we all want to see, including calling on Government to bring forward legislation in a new Rivers Act that will provide greater protection for rivers in law.
“We know we need to go further and water companies want to invest more to improve infrastructure and stop harm from storm overflows and outfalls.”
They added water companies did not have all the answers and making improvements would involve collaboration with Government, regulators and other organisations.
South West Water Spokesperson said: “We are absolutely committed to improving bathing and river water quality for the benefit of everyone, today and for generations to come. Having invested £9 billion across our infrastructure and treatment works, our analysis shows we have some of the best waters in Europe, this year achieving the highest ever bathing water quality at 100% across the South West.
“We have halved pollutions against last year, we are on track to increase monitoring and reduce usage of storm overflows and our continued investment will reduce our impact on river quality by 1/3 by 2025.”
