Has sewage been illegally dumped into Lake District protected site?
By Rob Windscheffel
Campaigners are calling for regulators to urgently investigate whether water company United Utilities has been illegally spilling
sewage
into one of the UK's most protected sites.
In the heart of the
Lake District
, Esthwaite Water was eulogised by poet William Wordsworth and was described by author Beatrix Potter as her 'favourite lake'. Today it's a Site of Special Scientific Interest (SSSI) and a RAMSAR wetland site of international importance.
Following a lengthy battle, which involved the intervention of the Information Commissioner, campaign groups Save Windermere and Windrush Against Sewage Pollution (WASP) obtained data from United Utilities about the Esthwaite Lodge Pumping Station. The pumping station has an emergency overflow which feeds into the lake and in emergencies is allowed to release sewage. That, however, doesn't include periods of heavy rain.
Professor Peter Hammond analysed the data and produced a report, shared with Channel 4 News, and believes the overflow might have spilled sewage at least 20 times since 2020. If those spills weren't as a result of major failures at the pumping station and caused by heavy rain, they could be in breach of their permit.
Campaigner Matt Staniek says: 'It's just been slowly putting sewage into the environment and the result of that is we're seeing this water quality decline. And then we're seeing this flow down to Windermere which obviously now goes green every summer.'
United Utilities
categorically deny there have been any spills from the site since 2017. They say they carried out an investigation in July 2024 and that their pear float used to detect spills 'was proven to be highly inaccurate and unreliable'. They also say their ultrasonic level monitor was set incorrectly and that 'data prior to June 2024 has been confirmed to be inaccurate and, therefore, cannot be used to confirm the occurrence of any spills'.
In response to United Utilities denying the accuracy of the data and the analysis done on it, Matt Staniek has told Channel 4 News: 'We had to go through hoops to try and get the data and it was only following the intervention of the Information Commissioner that they finally released the data to us. And then the first thing they say to us is you can't trust the data.
'If the data's unreliable, why haven't they acted in the last 10 years when the alarm's been going off saying it's spilling? Have they deliberately ignored that? Or have they just not been competent enough to do their job? It's blatantly incompetence or deliberate neglect.'
Professor Peter Hammond says: 'When you ask for the detailed data the water companies know you're going to find the evidence, so they say no or they take time to give you the evidence and it's been an uphill battle.'
While water companies say they are increasingly more transparent, and more data is being published, campaign groups believe there is still some way to go.
The Information Commissioner's Office has had to intervene 13 times in data disputes with water companies in the last year – 11 of those with United Utilities.
Information Commissioner John Edwards says: 'The water industry has not been as transparent as we would like. People do not expect to swim in polluted water. People expect to have clean and transparent water. We expect to have transparent water companies.
'We've seen movement in the right direction, a greater willingness to put more information out there. What that's exposing is some data quality issues.'
A United Utilities spokesperson said: 'Reports of any spills from Esthwaite pumping station are wrong and we have already provided the evidence and data that shows this.
'Transparency and customer confidence is extremely important to us and over the last year we have invested to improve our performance in this area. Last year, we issued over 16 million rows of data in response to environmental information requests and are on track to provide more than 17 million rows of data this year.
'To ensure this information is accessible to the public, we publish our responses on our website. This provides a central repository for the public to review data that has already been disclosed, and are currently meeting our target of responding to 100% of environmental information requests within the required service levels. There is always more to do and we have a plan for further improvements that will be delivered over the next 12 months.'
An Ofwat spokesperson said: 'In November 2021 we announced an investigation into all wastewater companies in England and Wales, looking into how companies are operating their wastewater treatment works and networks, including spills from overflows.
'This resulted in us opening an enforcement case into United Utilities in July 2024 which is on-going. In the last three months alone, we have concluded similar cases against other water companies resulting in Ofwat confirming over £160m in a combination of penalties and enforcement settlement packages. Given this is an active investigation, we cannot comment further but welcome the information that has been shared with us.'
An Environment Agency spokesperson said: 'We are currently investigating a number of United Utilities' sites including those on the Esthwaite catchment. If any of these sites are found to be in breach of environmental permits or causing pollution we will take appropriate enforcement action, up to and including criminal prosecutions.
'We've modernised our approach to regulating the water sector, with more regulation and enforcement officers, better data and are on track to carry out 10,000 inspections this year, all of which is holding water companies to account more than ever before.'

Magor and Pontypool fouled by water company
Dwr Cymru Welsh Water, pleaded guilty to two offences of knowingly permitting the discharge of poisonous, noxious or polluting matter into inland fresh water. The offences involved raw sewage and took place over one day in Pontnewynydd, Pontypool and over a 12 month period, in Magor. Welsh Water, the not-for-profit utility, allowed sewage to leak into a sensitive area on the Gwent Levels at Magor and at a brook in Herbert's Wood, north of Pontypool. The brook is a tributary of the Afon Lwydd, a river that flows through major population centres before entering the Severn Estuary. Newport magistrates heard that Welsh Water allowed a broken sewer line to discharge raw sewage into a reen and salt marsh near Magor, over a whole year. Natural Resources Wales had to take enforcement action at the sensitive site, the court heard. Welsh Water had repeatedly failed to repair essential plant and effectively manage the site. The offences occurred between January 2023 and January 2024, the court was instructed. The Magor area contains a delicate salt marsh environment and has several areas designated as Sites of Special Scientific Interest (SSSI). Furthermore, the wider area has a Special Area of Conservation (SAC) and Special Protection Area (SPA). Welsh Water was fined £90,000 for the Gwent levels incidents and £160,000 for the Pontnewynydd incident, which was caused by a spillage from a foul sewer chamber in February 2023. They were also ordered to pay more than £18,000 in costs. Welsh Water had earlier pleaded guilty to the charges. Of the damage in Pontnewynydd, Natural Resources Wales said sewage was visible over ground and throughout approximately 400m of the tributary. Speaking of the Magor incidents, they said: 'For over a year, our officers recorded a pattern of recurring sewage pollution incidents in the same area, impacting a highly protected habitat which is rich in plants and wildlife, including a saltmarsh. 'Time and again we were assured that necessary repairs had been made, yet the pollution persisted. 'As well as causing considerable harm to the local environment, we found Welsh Water's response to the incidents to be inadequate. Communication was at times poor, and there were unnecessary delays to their incident response procedures such as pumping and tankering away the pollution, which could have lessened impact."

Dŵr Cymru Welsh Water fined for £250,000 sewage pollution
Dŵr Cymru Welsh Water have been fined £250,000 for multiple cases of sewage pollution on the Gwent Levels and another on a tributary of the Afon Llwyd. Natural Resources Wales took enforcement action after a broken sewer line discharged raw sewage into a reen and salt marsh near Magor, Monmouthshire between 24th January 2023 and 11th January 2024 The area of salt marsh falls within the several protected sites - a Site of Special Scientific Interest (SSSI), a Special Area of Conservation (SAC), RAMSAR and Special Protection Area (SPA). Officers from Natural Resources Wales were first called to the site, near the sea wall at Magor, on January 24 2023. A section of the south east coast sewer line was found to have ruptured, discharging sewage into an area known as 'back ditch". Although repairs were made to pipe, NRW officers were called to further incidents at the site in March and May 2023, and also on January 2024. Dŵr Cymru Welsh Water was been fined £90,000 for the the Gwent levels incidents, and a further £160,000 for an incident on a tributary of the Afon Llwyd at Herberts Wood, Pontnewynydd. In the latter incident, in February 2023, the source was a spillage from a foul sewer chamber. An NRW spokesperson said the sewage was visible over ground and throughout approximately 400m of the tributary. At Newport Magistrates Court, the company was also ordered to pay costs and a surcharge of £18,320.77. 'For over a year, our officers recorded a pattern of recurring sewage pollution incidents in the same area, impacting a highly protected habitat which is rich in plants and wildlife, including Saltmarsh" said John Rock, NRW Operations Manager for South Wast Wales 'Time and again we were assured that the necessary repairs had been made, yet the pollution persisted. 'As well as causing considerable harm to the local environment, we found Dŵr Cymru Welsh Water's response to the incidents to be inadequate. Communication was at times poor, and there were unnecessary delays to their incident response procedures such as pumping and tankering away the pollution, which could have lessened the impact. A spokesperson for Welsh Water said it "pleaded guilty at the earliest opportunity" "At Herberts Wood, Pontypool, the incident occurred because of the damage to our sewer pipe caused by root ingress. "We manage a vast sewage network that spans over 36,000km of sewers and regrettably unexpected issues such as this can arise and it's not possible to foresee theme all. The repair was hindered as we had to work around a vast wooded area and the need to preserve the trees. This meant the sewer had to be diverted, prolonging the incident." "The second issue was on the South East Coastal Sewer. We have been experiencing repeat issues with this sewer in recent years with the only viable solution being to replace it." "However, the estimated cost of £80 million has meant that it has not previously been possible to complete the work within our maintenance budget." "We have now, with support of NRW, secured permission from Ofwat to raise funds to address the issue."
