Revealed: the ‘black box’ wastewater trade that rakes in millions for UK utility companies

Firms made more than £340m last year from processing industrial and commercial wastewater at sewage works that are unable to remove many chemical pollutants

Water companies in the UK made more than £340m in revenue last year by pouring billions of litres of industrial and commercial wastewater into sewage treatment works that experts say are not designed to remove most chemicals, leaving pollutants to pass into rivers, seas and farmland.

Water companies are required by law to take industrial wastewater and issue permits called “trade-effluent consents” that allow businesses to send it to sewage works, though water companies can refuse applications.

However, no independent regulator oversees the trade-effluent process and there is no central register, so Watershed Investigations, the Guardian and the campaign group River Action compiled a database of 26,000 consents, providing the first ever national picture of the system.

Toxic ‘forever chemical’ found in almost all rivers and groundwaters tested in England

A “forever chemical”, which Europe’s chemicals regulator says may damage babies in the womb and is suspected of harming fertility, has been found in rivers and groundwater across England, according to Environment Agency data obtained exclusively by Watershed and Unearthed.

The highest concentration of forever chemical TFA in surface water was found in the River Ancholme in Lincolnshire.  Image credit: Richard Croft

Revealed: how companies ‘secretly’ use billions of litres of public water in drought-hit England

As millions of people face hosepipe bans, many companies are not required to report, let alone cut, use of public supply.

Less than 1% of businesses in England use more water than the daily needs of 10 million people, as millions of households face hosepipe bans and three-quarters of the country is in drought.

Businesses across England use 2.6bn litres a day from the public water supply, which includes potable and non-potable water provided by water companies. In total, businesses account for about 30% of public supply use, with two-thirds of their consumption in water-stressed areas, according to Mosl, the organisation that operates England’s business water market.

“Nobody trusts the water, not with all the cancers,” Chief Tuccaro.

Canada’s oil companies want permission to treat and release toxic waste from Alberta’s tar sands into the Athabasca River — the same river that flows into the drinking water supplies of First Nations communities. But many First Nations leaders say they’re already carrying an unbearable burden from the world’s fourth‑largest oil reserve, with health impacts that continue to mount.

‘Forever chemicals’ in water linked to film studio

The site of a former film studio has been investigated as a possible source of “forever chemicals” found in groundwater, a water company said.

‘Drinking from a fetid pond’: superbug-creating genes found in UK’s largest lake

Watershed detected genes capable of creating antibiotic-resistant superbugs in the UK’s largest lake, which supplies drinking water to about 40% of Northern Ireland.

Our testing of water from Lough Neagh, which has a surface area 26 times bigger than Windermere, found genes resistant to a wide range of antibiotics, including carbapenems – drugs reserved for life-threatening infections when all other treatments have failed.

The discovery comes as deaths linked to antibiotic-resistant infections are rising worldwide. Nearly 400 resistant infections are reported each week in England, with deaths linked to them reaching an estimated 2,379 in 2024, according to UK Health Security Agency data.

The World Health Organization (WHO) describes this antimicrobial resistance (AMR) as “one of the most urgent, complex and frightening health challenges of our time”.

The article was published in the Guardian: 

Watershed spoke about the findings on BBC R4’s Rare Earth and BBC Northern Ireland’s The Nolan Show.

Race to find source of carcinogenic PFAS in Cumbria and Lancashire waters

Watershed uncovered a string of toxic pollution hotspots across Cumbria and Lancashire, with high levels of the banned cancer-causing “forever chemical” Pfos detected in rivers and groundwater at 25 sites.

The contamination, spread across a large area, was uncovered by Watershed Investigations and the Guardian after a freedom of information request revealed high concentrations of Pfos in Environment Agency samples taken in January 2025.

Who’s in control of our water supplies?

Rachel Salvidge

Who’s in charge? Is anyone driving this bus? I can’t shake the feeling that everyone thinks someone else is in control, while we freewheel towards catastrophe.

Not least because we’re entering a global era of ‘water bankruptcy’, according to the UN. Water-related violence is spiking. Most big cities now sit in high water stress regions. Large swathes of Europe are drying out. I’ve written about all this and mapped it on a new Water Security Atlas: 

Back home, things aren’t much better. Taps ran dry at one end of the country last month, while at the other people did backstroke in their kitchens. On the very edges some people’s actual houses fell into the actual sea. 

Ergo, someone’s not got a handle on water supplies, despite all the demand forecasts. Someone else can’t predict the floods that have been in climate projections for decades. And someone’s been studiously ignoring coastal erosion, despite it being as reliable as the tides. 

Successive governments and regulators were supposed to make sure this rainy island has enough water to avoid shortages. They were supposed to prevent profiteering private interests from treating our rivers like open sewers. They were supposed to defend us from floods or at least help us get out of the way. 

It doesn’t seem to be going so well. 

I’ve examined the water supply situation and it appears regulators don’t have a clear grip on who’s using what. Worse still, they’ve known for years that many of England’s water companies aren’t doing enough to secure our drinking water into the future.

Smash cut to the people of Kent and Sussex: taps dry, blood boiling, swearing at water tankers in the streets. 

These events were foretold and promptly foreignored, as I’ve set out in a number of articles. The most recent show that the Government, Environment Agency and Ofwat had warned South East Water about its supplies years before the recent outages. 

And it’s not the only water company that has been warned about supply risks. Far from it: 

Overall, management of water supplies looks iffy. I found this repeatedly while reporting a series of Guardian investigations — particularly because the system is so patchy and opaque that it’s difficult to determine who is using what, and therefore almost impossible to control the resource. Here’s what I found…

Moves are afoot, though. The government has laid a Water White Paper before Parliament, promising to do better. There is some good stuff in it but not enough about preventing pollution, and not enough about bringing the water sector properly into line.

The paper says the government is considering changes to how abstraction (taking water from the environment) is managed. That reform is critical if we’re ever to get a proper grip on supplies. But it’s also been promised for as long as I’ve been a journalist. Which is a long time.

So for now, we trundle on, driverless, towards the gorge. The only question is whether there will be any water at the bottom of it.

Dramatic rise in water-related violence

Water-related violence has almost doubled since 2022 and little is being done to understand and address the trend and prevent new and escalating risks, experts have said. There were 419 incidents of water-related violence recorded in 2024, up from 235 in 2022, according to the Pacific Institute, a US-based thinktank. The institute has compiled evidence of hundreds of years of water-related conflicts, including cases of water being a trigger for violence, a weapon of conflict or a casualty of conflict

Water companies warned of problems years before supply outages

South East Water was warned of supply problems years before the taps ran dry, Watershed revealed. Regulators repeatedly told the company it did not have enough water to meet demand in two areas that lost supplies.

It was among many water companies that were warned by Defra, Ofwat and the Environment Agency about supplies and leakage. Watershed secured coverage in The Times, on ITV News and LBC, and on Yahoo News and local media.
