Sewage spilled illegally into England’s biggest lake on a document selection of days remaining yr, an research of water corporate knowledge by means of campaigners suggests.
The research, which the BBC had unique get right of entry to to, used United Utilities operational knowledge to determine when the corporate used to be discharging sewage into Windermere when it must by means of regulation were treating a few of it.
The campaigners from Windrush In opposition to Sewage Air pollution (WASP) and Save Windermere recognized 140 unlawful spill days in 2024, greater than in any of the 3 earlier years.
United Utilities instructed BBC Information that the campaigners’ findings have been “faulty” and one of the crucial knowledge “faulty”.

Windermere is one in all Britain’s maximum cherished good looks spots
Closing week the Surroundings Company mentioned United Utilities had spilled 77,817 instances in 2024, the best determine of all England’s water firms.
Most of the spills can have been prison. All water firms are legally allowed to discharge uncooked sewage to prevent the community getting beaten and this now occurs continuously all the way through classes of heavy rain.
However nearly all pumping stations and remedy crops perform underneath an environmental allow which specify that they should procedure or “move ahead” a specific amount of sewage and rainwater prior to spilling begins.
The campaigners cross-referenced United Utilities datasets appearing when an asset used to be spilling in opposition to how a lot sewage it used to be treating on the time. The campaigners’ research – which has been shared with and scrutinised by means of the BBC – discovered days when unlawful spills seem to have befell at every of six sewage amenities across the lake, which mixed to 140 days in 2024. That is greater than in any of the former 3 years, because the chart beneath presentations.
The longest unlawful spill the research recognized used to be for 10 days from Hawkshead pumping station, which flows into Windermere by way of Cunsey Beck.
“This is a sign that their works have now not been maintained correctly or they are now not being watched over correctly,” says Prof Peter Hammond, a mathematican and retired educational from marketing campaign crew Windrush In opposition to Sewage Air pollution.
Prof Hammond’s research of water corporate knowledge has been cited by means of regulators and he has been praised in Parliament by means of water corporate executives for bringing issues to mild they have been prior to now blind to.
The newest research covers 4 years of knowledge from six websites that discharge sewage into the Lake Windermere catchment.
Comparisons over an extended time frame are inconceivable as United Utilities has handiest had made complete knowledge units to be had since 2021.

The regulators Ofwat and the Surroundings Company have since 2021 been investigating whether or not the water firms were treating sufficient sewage prior to they begin to spill. The EA name it a “primary felony investigation” whilst Ofwat name it “the biggest and most complicated Ofwat has ever undertaken”.
Closing week Yorkshire Water agreed to a £40m “enforcement motion” after Ofwat exposed “severe screw ups” in the way it operated its remedy plant and community.
Ofwat declined to remark at the campaigner’s findings as their investigation into United Utilities is ongoing.
According to issues about United Utilities the Surroundings Company remaining yr reviewed all of its environmental allows within the Windermere catchment and says this led without delay to the water corporate tripling its funding plans for the world to £200m.
“We’re these days sporting out investigations into suspected air pollution incidents at the Windermere catchment and are not able to touch upon those intimately till they have got reached a conclusion,” an EA spokesperson mentioned when the campaigners’ research used to be shared with them.
“The place we discover breaches of environmental allows, we will be able to take the proper enforcement motion as much as and together with a felony prosecution.”

United Utilities, which gives products and services to greater than seven million other people throughout north-west England, is greater than £9bn in debt. Its leader govt Louise Beardmore showed to parliament in February that she used to be remaining yr paid £1.4m together with an advantage of £420,000.
“The method utilized by the campaigners is other to that utilized by the Surroundings Company for its compliance exams,” the water corporate mentioned in a observation.
“On most sensible of that, faulty knowledge has been used, tags and naming conventions in knowledge units seem to have been misunderstood, and assumptions appear to have been made on whether or not several types of float meters were put in.”
“The method fails to make use of different corroborating data from the websites which might turn out that spills didn’t happen. Because of this, the numbers quoted are faulty.”
BBC Information introduced United Utilities with 5 examples of unlawful spills the campaigners’ research had recognized the use of the corporate’s knowledge and requested for any proof or rationalization as to why they weren’t unlawful. United Utilities time and again declined to take action in writing or on digital camera.
“What we are seeing is the failure of privatisation. We are seeing a prioritisation of dividend returns over the long-term environmental coverage of puts like Windermere” says Matt Staniek from Save Windermere.
“The invoice payer has paid for a carrier that hasn’t ever totally been equipped, and the illegality demonstrates that for all to look.”
Over the following 5 years expenses within the United Utilities house will move up by means of 32% above the velocity of inflation. On moderate that may imply a upward push of £86 for the yr that begins in April.
Louise Beardmore mentioned the rises will fund the “biggest funding in water and wastewater infrastructure in over 100 years”.
For Windermere that is set to imply 9 wastewater remedy works, together with two that have been incorporated within the campaigners’ research being upgraded and a discount within the selection of overflows discharging into the lake.
