Activists warn of ‘extreme anger’ if ministers fail to reform water regulator

Anti-sewage campaigners have warned of “extreme anger” if the Labour government does not radically reform the water regulator.Sources at the Environment Agency (EA) and in the Labour party have told the Guardian that while Labour had spent time considering reforms of the EA and Ofwat in order to fix the sewage crisis, some stricter options that had been proposed were now off the table.Campaigners say the watchdog, Ofwat, has been too lax on the water companies and prioritised low bills over spending on improving sewer systems.Last year there was a 105% rise in raw sewage spills into England’s rivers and seas – it was discharged for more than 3.6m hours and this made 2023 the worst year for storm water pollution.Options sources say have been discussed with campaigners, the EA and other stakeholders included merging Ofwat and the EA, giving Ofwat more powers and a policy prioritising environmental benefits over costs to consumers, and giving the regulators more independence from government.At the moment, for example, the EA shares a press office with Defra and its communications are directed by ministers, which makes it difficult to take long-term actions that the government could think too politically damaging, or to hold the government to account.The EA faced steep funding cuts under Conservative government austerity which has made it difficult for the regulator to enforce environmental laws. Proposals to increase its funding will not be taken forward, the Guardian has been told.Now policies that campaigners say are less ambitious have emerged and include working with the EA to stop water company self-monitoring for sewage spills – an initiative that was already happening under the Conservative government – and writing to Ofwat to ask them to make sure funding for vital infrastructure investment is ringfenced and can only be spent on upgrades benefiting customers and the environment.The environment secretary, Steve Reed, has asked Ofwat to ensure that when money for investment is not spent, companies refund customers, with money never allowed to be diverted for bonuses, dividends or salary increases.Charles Watson, the founder of River Action, said the government had promised regulatory reform of the water companies, adding: “Fixing the nation’s failed environmental regulatory system was rightly a central part of Labour’s environmental campaigning promises during the general election.“A root cause of the extensive pollution of our waterways is the combination of Ofwat’s allowing of the water companies to pay out too much to shareholders at the expense of infrastructure investment and the Environment Agency’s failure to enforce existing regulations – thus enabling polluters to be able to act freely with impunity.“[Failing to address these problems] will be met with extreme disappointment and anger by the huge numbers of the public who voted on 4 July to clean up our waterways.”Surfers Against Sewage campaigners stage a protest against filthy waters at Gyllyngvase beach in Falmouth, Cornwall, last year.

Anti-sewage campaigners have warned of “extreme anger” if the Labour government does not radically reform the water regulator.

Sources at the Environment Agency (EA) and in the Labour party have told the Guardian that while Labour had spent time considering reforms of the EA and Ofwat in order to fix the sewage crisis, some stricter options that had been proposed were now off the table.

Campaigners say the watchdog, Ofwat, has been too lax on the water companies and prioritised low bills over spending on improving sewer systems.

Last year there was a 105% rise in raw sewage spills into England’s rivers and seas – it was discharged for more than 3.6m hours and this made 2023 the worst year for storm water pollution.

Options sources say have been discussed with campaigners, the EA and other stakeholders included merging Ofwat and the EA, giving Ofwat more powers and a policy prioritising environmental benefits over costs to consumers, and giving the regulators more independence from government.

At the moment, for example, the EA shares a press office with Defra and its communications are directed by ministers, which makes it difficult to take long-term actions that the government could think too politically damaging, or to hold the government to account.

The EA faced steep funding cuts under Conservative government austerity which has made it difficult for the regulator to enforce environmental laws. Proposals to increase its funding will not be taken forward, the Guardian has been told.

Now policies that campaigners say are less ambitious have emerged and include working with the EA to stop water company self-monitoring for sewage spills – an initiative that was already happening under the Conservative government – and writing to Ofwat to ask them to make sure funding for vital infrastructure investment is ringfenced and can only be spent on upgrades benefiting customers and the environment.

The environment secretary, Steve Reed, has asked Ofwat to ensure that when money for investment is not spent, companies refund customers, with money never allowed to be diverted for bonuses, dividends or salary increases.

Charles Watson, the founder of River Action, said the government had promised regulatory reform of the water companies, adding: “Fixing the nation’s failed environmental regulatory system was rightly a central part of Labour’s environmental campaigning promises during the general election.

“A root cause of the extensive pollution of our waterways is the combination of Ofwat’s allowing of the water companies to pay out too much to shareholders at the expense of infrastructure investment and the Environment Agency’s failure to enforce existing regulations – thus enabling polluters to be able to act freely with impunity.

“[Failing to address these problems] will be met with extreme disappointment and anger by the huge numbers of the public who voted on 4 July to clean up our waterways.”

Millions of households face jump in water bills after regulator backs more price rises

Competition watchdog agrees requests from Anglian, Northumbrian, Southern, Wessex and South East to raise household billsBusiness live – latest updatesWater bills for millions of households in England will increase by even more than expected after the competition regulator gave the green light for five water suppliers to raise charges to customers – but rejected most of the companies’ demands.An independent group of experts appointed by the Competition and Markets Authority (CMA) decided provisionally to let the companies collectively charge customers an extra £556m over the next five years, it said on Thursday. That was only 21% of the £2.7bn that the firms had requested. Continue reading...

Water bills for millions of households in England will increase by even more than expected after the competition regulator gave the green light for five water suppliers to raise charges to customers – but rejected most of the companies’ demands.An independent group of experts appointed by the Competition and Markets Authority (CMA) decided provisionally to let the companies collectively charge customers an extra £556m over the next five years, it said on Thursday. That was only 21% of the £2.7bn that the firms had requested.The five companies – Anglian, Northumbrian, Southern, Wessex and South East – together serve 14.7 million customers. The changes will add 3% on average to those companies’ bills, on top of the 24% increase previously allowed.The companies appealed to the CMA in February for permission to raise bills by more than allowed previously by the industry regulator, Ofwat. They argued they needed more to meet environmental standards.Water bills have become the subject of significant political controversy in recent years in the UK amid widespread disgust over leaks of harmful sewage into Britain’s rivers and seas.Emma Hardy, the water minister, said: “I understand the public’s anger over bill rises – that’s why I expect every water company to offer proper support to anyone struggling to pay.“We’ve made sure that investment cash goes into infrastructure upgrades, not bonuses, and we’re creating a tough new regulator to clean up our waterways and restore trust in the system.”English and Welsh water companies are mostly privately owned, but the prices the local monopolies can charge customers are regulated by Ofwat over five-year periods. Ofwat in December said average annual household bills could rise by 36% to £597 by 2030 to help pay for investment.Ofwat said the companies could spend £104bn in total, paid by consumers.The allowed bill increases stopped well short of the water companies’ requests. The CMA said the expert panel had largely reject companies’ funding requests for new activities and projects beyond those agreed by Ofwat. However, the panel did allow more money for returns to investors, to reflect sustained high interest rates since the bills increases were approved.Anglian Water, serving the east of England and Hartlepool, asked for the average annual household bill to rise to £649 – a 10% increase – but was granted only £599, or 1%. Northumbrian, mainly in north-east England, asked for £515, or 6%, and was given £495, also 1%.South East Water, which only provides drinking water and not sewage services in several home counties, asked for an 18% increase to £322, but was allowed 4% to £286. Southern Water, on England’s south-east coast, asked for a 15% increase to £710. That would have been the highest bill in England and Wales, but it was allowed only a 3% increase to £638.Wessex Water in south-west England asked for an 8% increase to £642, and was granted the biggest proportional increase on appeal of 5% to £622.The CMA and other regulators have faced pressure from the Labour government to put more focus on economic growth. The chancellor, Rachel Reeves, this year appointed former Amazon boss Doug Gurr to lead the CMA.Kirstin Baker, the chair of the group that decided on the appeals, said: “We’ve found that water companies’ requests for significant bill increases, on top of those allowed by Ofwat, are largely unjustified.skip past newsletter promotionSign up to Business TodayGet set for the working day – we'll point you to all the business news and analysis you need every morningPrivacy Notice: Newsletters may contain information about charities, online ads, and content funded by outside parties.

Mike Keil, chief executive of the Consumer Council for Water, which represents consumers, said “further increases will be very unwelcome”, and questioned whether the CMA should have allowed higher returns for investors.“There is a danger the customers of these companies will end up paying more, without seeing any additional improvements in return,” he said.Environmental groups have questioned why companies are allowed to return cash to shareholders while continuing to pollute Britain’s rivers and seas. James Wallace, chief executive of River Action, a campaign group, said: “Once again, water bill payers are forced to shoulder the cost of decades of failure.“Millions of households in England face higher bills while rivers continue to suffer from mismanagement by privatised water companies. In 2024 alone, four of these five companies were responsible for at least 1.4m hours of sewage discharges into rivers and seas – a stark illustration of ongoing environmental harm.”The CMA group’s decision will also be carefully considered by Thames Water, Britain’s biggest water company with 16 million customers. Thames also appealed initially but has agreed to pause it while the utility and its creditors negotiate with Ofwat over a restructuring plan to try to cut its debt burden and prevent it collapsing into temporary government control.Thames is still considering a request for a further £4bn. People close to Thames Water had criticised Ofwat’s approach to the price determination, arguing that the utility needed much more cash to turn around its performance on pollution.The best public interest journalism relies on first-hand accounts from people in the know.If you have something to share on this subject you can contact the Business team confidentially using the following methods.Secure Messaging in the Guardian appThe Guardian app has a tool to send tips about stories.

South Africa’s Coast Is Rising—And Scientists Have a New Explanation Why

Human water management contributes to sinking land across the globe, and it may also be responsible for an unexpected rise

October 7, 20254 min readSouth Africa’s Coast Is Rising—And Scientists Have a New Explanation WhyHuman water management contributes to sinking land across the globe, and it may also be responsible for an unexpected riseBy Avery Schuyler Nunn edited by Sarah Lewin FrasierLand rising along South Africa’s coast may be closely tied to humans’ use of water. For decades geologists thought the slow rise of South Africa’s southern coast was driven by forces deep below—buoyant plumes of molten rock ascending through Earth’s mantle and heaving the crust upward over millions of years. But now satellite data and precise GPS measurements are tilting such assumptions off their axis. A study in the Journal of Geophysical Research: Solid Earth suggests this land rise may have less to do with deep tectonic forces and more to do with missing groundwater just under our feet.Human activity has long been depleting South Africa’s groundwater. In 2018, after grappling with severe droughts for years, the country came close to a full-blown water emergency when Cape Town was nearly the world’s first major city to literally run out of water—a scenario dubbed “Day Zero.” For several months that year the city’s residents faced the very real prospect of having to regularly queue for critically limited water supplies, an outcome staved off only by timely rainfall and intensive water-saving campaigns. The extreme shortage resulted from a combination of climate change and unsustainable water use, which drained surface reservoirs and placed mounting pressure on aquifers across the region.The recent study hypothesizes that the ground, once compressed by the sheer weight of the surface water and groundwater above it, is now expanding like a foam mattress relieved of pressure. Using GPS and satellite gravity data from between 2000 and 2021, the researchers detected a roughly six-millimeter rise in the land surface—a shift that coincides with humans’ depletion of South Africa’s water reserves and periods of drought.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.“Sometimes the first explanation isn’t necessarily the right one,” says University of Bonn geodesist Christian Mielke, the study’s lead author. “Perhaps it isn’t plate tectonics after all.”That misunderstanding, not necessarily the rising land itself, may be the most striking thing about South Africa’s situation. What was once chalked up to the slow churning of Earth’s mysterious and inaccessible interior may instead reflect human activity, especially our management—or mismanagement—of water.“The presence of water, either as ice and snow on the land surface or as groundwater below, and the removal of that water are intimately tied to the deformation of the ground’s surface,” says Stanford University geophysicist Rosemary Knight. In most places around the globe, this process usually leads to sinking, called land subsidence, to fill the gap.But in South Africa, the new study suggests, that tie between water and land movement shows up in a surprising way. During the rainy season, rivers and reservoirs fill, adding weight that presses the crust down. In the dry months, much of that water either evaporates or gets pumped away, and the land rebounds upward. Over time the long-term loss of groundwater tips the balance toward uplift rather than sinking.This “seasonal breathing” is the giveaway that the cause is probably not solely a mantle plume. If molten rock were pushing upward, the motion would be steady, not tied to rainfall cycles. The expansion, if verified, could be yet another example of the ways human water use is reshaping the planet.From 1945 to 1970 more than 13,000 square kilometers of California’s San Joaquin Valley, once hailed as a “land of milk and honey” for Dust Bowl migrants, sank by at least 30 centimeters—and in some places by nearly nine meters. The San Joaquin sinking has only sped up since then, and parts of the valley drop more than 30 centimeters a year during severe droughts. On average, the pace has accelerated by 70 percent from the mid-20th century.Something similar is happening to the Chesapeake Bay, which, with its sweeping estuaries and lush tidal wetlands, is one of the U.S. East Coast’s most ecologically significant regions. Here land subsidence—driven by both groundwater extraction from aquifers and the lingering effects of ancient glacial shifts—is accelerating flood risk and relative sea-level rise. Satellite data, tide gauge records and projections from the Intergovernmental Panel on Climate Change suggest that by 2100 the combination of subsidence and sea-level rise could inundate up to 1,100 square kilometers of the Chesapeake Bay’s coastline.Mielke notes that such findings highlight the complexity of the planet’s response to human-induced environmental change. The consequences are still gradually being uncovered, and the implications may be profound. As climate change accelerates, land movements could exacerbate other challenges, especially in coastal areas with rising seas.To monitor such hidden shifts on a global scale, scientists use the GRACE satellite mission (Gravity Recovery and Climate Experiment) to detect changes in Earth’s mass by measuring minuscule variations in gravity. Because water has weight, depleting or replenishing groundwater subtly alters the planet’s gravitational field, which GRACE can detect from orbit.Knight and other researchers are looking for ways to keep land from shifting on such a vast scale by maintaining a careful balance. “Basically you get subsidence when water out exceeds water in,” Knight says. “And for water in, the term that’s used is ‘recharge.’”Some recharge happens naturally as rain or snowmelt soaks into the soil, but this precipitation isn’t enough to offset decades of groundwater extraction and current demand. That’s why places such as California are now turning to managed aquifer recharge: strategically spreading excess surface water (such as winter floodwaters) across land where it can percolate into the ground and rebuild depleted reserves, or injecting water directly into aquifers. Estimates suggest there is space underground for a total amount of water 30 times the volume of California’s Shasta Lake, enough to begin reversing the land’s descent.As Knight puts it, the solution can’t be about just cutting back on groundwater pumping. It must involve replenishment: restoring water to the ground from which it was drawn.It’s Time to Stand Up for ScienceIf you enjoyed this article, I’d like to ask for your support.

Cold-Water Immersion May Offer Health Benefits -- and Also Presents Risks

Claims about the benefits of cold-water immersion date back centuries

Dr. Mark Harper recalls his first cold-water swim in the south of England 20 years ago. It was August, but the initial jolt from the plunge took his breath away. The shock to his system lasted a minute or two until he was “recombobulated and able to think about something other than the cold," Harper says. A surprise sensation soon replaced his discomfort. “I remember getting out of the water the first time and feeling so good," Harper, an anesthesiologist who has since researched the potential risks and rewards of taking a nippy dunk. "I wasn't expecting that.”Claims about the benefits of cold-water immersion date back centuries. Thomas Jefferson, the principal author of the Declaration of Independence and the third American president, wrote toward the end of his life about using a cold foot bath daily for 60 years. He also owned a book published in 1706 on the history of cold-water bathing. But Harper, who became a regular cold-water swimmer after his initiation, said there are strong signs that people can derive mental health benefits from the activity. He mentioned a positive effect on depression and general well-being.“For now, we have a very strong base, but not hard evidence, that cold-water immersion is effective for mental health," Harper told The Associated Press. Harper said his own early experiences with cold-water swimming piqued his professional curiosity. As a physician, he wondered if the brief bodily shock had clinical uses for treating depression. He cited the biological phenomenon of hormesis, in which a stressor introduced at a low dose creates a positive response.Muscles and bones put under stress —for example, with weight-bearing exercise — also respond and grow.Harper acknowledged that the positive effects he's observed may be the result of the placebo effect, a phenomenon in which people who are given a medicine they think will help them report responding to the treatment even if it had no active ingredients. In the case of cold-water immersion, the benefits may come from meeting people, the exercise itself, or simply accepting a challenge and accomplishing it, which improves self-confidence, he said.“Personally, I think it’s all of those things, and the cold has an additive effect,” Harper said. “I think we have a good physiological basis for that. The basic science tells us the cold has a very strong effect on the body.“What we’re talking about is an intervention, when it's used clinically, that produces beneficial effects on mental health. So in a way it doesn’t matter which aspect is generating the positive effects.”Harper cited what he said was a common reaction among first-timers who have taken the plunge.They often say “the fact that I’ve done this means I can do anything,” he said. “It’s quite a confidence builder and it’s something people stick to because they enjoy it so much.” Know the risks when you start Dr. Mike Tipton, a physiologist at the University of Portsmouth in England who has studied extreme environments, authored a paper along with Harper and two more researchers several years ago. The title highlighted the potential advantages and dangers of stimulating the body with a sudden drop in temperature: “Cold Water Immersion: Kill or Cure.” “Like other environmental constituents such as pressure, heat and oxygen, cold water can be either good or bad, threat or treatment depending on circumstance,” they wrote after reviewing the research then available on the topic. One of their findings: The activity presents dangers. Deaths from cold-water immersion are not uncommon. The shock of frigid water can cause people to hyperventilate and drown. But Tipton told The AP the risks can be managed with common sense and precautions.You do not need to go to extremes to get a potential payoff. Entering water at a temperature of 20-15 degrees Celsius (68-59F) and staying for only a few minutes is sufficient.Tipton explained if the water is colder than that, you may get more benefit — but limit your exposure.“If you ask me what protocol you would follow if you thought this was going to be doing you good, I wouldn't go in water much below 12C (54F), and I wouldn’t stay in for much more than two minutes,” Tipton said.Tipton and Harper both said that any benefits from cold-water immersion come from the body's cold-shock response: the sudden fall of skin temperature, the release of the stress hormones, the release of endorphins, and the anti-inflammatory effect. Tipton cautioned against long spells in an ice bath.“Sitting in water for as long as I can fills me with horror,” Tipton said. "This could destroy small nerves, blood vessels in extremities and could result in amputation the same way frostbite can."Harper, who has swum as long as four-hour stretches in open water, advised vigilance.“People think it’s got to be super cold, super long and the longer the better,” Harper said, "and that’s wrong.” Be safe. You're a tropical animal Tipton said he's not trying to be the “fun police” but suggested caution and a medical screening if you take the plunge. He said humans are considered “tropical animals” who need to adapt to the cold and are better suited to warm conditions. A human’s resting body temperature is about 36.5 to 37.5 degrees Celsius (97.7 to 99.5F). Because of that, cold-water immersion is stressful and carries risks for the cardiovascular and respiratory systems. Not to mention the risk of drowning.“We don’t want to stop people doing it, but we want to make sure they do it in a way that maximizes the benefits and minimizes the risks,” Tipton said.He suggested swimming in a life-guarded area, or going with experienced outdoor swimmers. He also suggested knowing the body of water you're swimming in. Hazards, among others, include tides, temperature, depth and pollution.“Understand that taking a tropical animal and putting it in cold water is probably the greatest stress that most people will experience in their life,” Tipton said.He suggested entering the water in a controlled fashion instead of jumping in. "Be sensible about it,” he said. “Incremental is the key.”Copyright 2025 The Associated Press. All rights reserved.
