SE Water Failures were “Forseeable and Preventable”

A new expert report has said that South East Water was wrong to blame its failures in Tunbridge Wells at the end of last year on a bad batch of chemicals and unusual fresh water supplies.

A detailed report by the government agency, the Drinking Water Inspectorate or DWI, into the collapse of the supply to 60,000 customers says there is no evidence for either theory.

The DWI instead has concluded that South East Water’s failures were “foreseeable and preventable” and the company has now been placed into a so-called “transformation programme”.

The DWI explained: “A transformation programme is one of the most significant steps the Inspectorate can take. It is used when a water company has shown a pattern of serious or repeated failures that cannot be addressed through individual enforcement actions alone.”

The DWI statement issued on Tuesday continued: “Under a transformation programme, the Inspectorate works with the company to identify the root causes of poor performance and formalise these programmes into legal instruments, to deliver the changes needed to ensure consumers receive the reliable water supply they are entitled to expect.”

Local water industry expert, Charles Hedges (pictured below), told Southborough News: “A lack of maintenance, jar testing and recording of pH as well as undersized equipment highlights the lack of investments at Pembury – investments that should have occurred 30 years ago.”

Charles Hedges continued: “In its 2024 report, Ofawt records a series of failures by SE Water that go back to 2018. The DWI report of 2026 provides evidence of continued failures that reflect poorly on the technical leadership within the company.”

The DWI said the December disruption (mainly affecting the area shown above) originated at Pembury Water Treatment Works, where South East Water did not have sufficiently reliable systems in place to detect and respond to emerging issues in real time.

The DWI report states that: “The site had experienced earlier signs of instability that, if appropriately investigated and acted upon, would have prevented the works failure and subsequent loss of supply and impact on consumers.”

It continues: “Analysis of five years of raw water data demonstrated that raw water conditions prior to and during the event were within normal historic operating ranges. There is no evidence of a sudden change in raw water quality which would explain a sudden treatment failure.”

The DWI states: “Raw water monitoring at Pembury was insufficient for effective process optimisation with no continuous temperature monitoring at the works inlet and pH and alkalinity sampling alone insufficient for short-term or real-time decision making without constant review. Regular jar testing to confirm optimal coagulant dose had not been performed despite this being a requirement under a regulatory notice.”

The report continues: “The company pursued a batch chemical (coagulant) batch theory during the early stages of the loss of supply event. The theory has since been disproven with the chemical being confirmed within specification. The focus on a bad batch theory also meant operational resource distracted from identifying the need and attempt to optimise the current coagulant and process. The reactive jar testing which was completed onsite was delayed by a day due to staff availability.”

The DWI concludes that the supply interruption and boil water notice “arose not from exceptional raw water conditions but from longstanding weaknesses in operational management, treatment optimisation, monitoring, maintenance and organisational preparedness at Pembury water treatment works. Taken together, the findings point to systemic and repeated failings across both operational control and emergency management arrangements, resulting in serious consumer impact.”

The chief executive of South East Water, Dave Hinton (pictured below), remains in his job despite the scathing report from the regulator.

The Environment Secretary Emma Reynolds said she had already “hauled in the CEO and Chair of South East Water to my office to ask them why we’re seeing repeated failures in leadership and service to customers, and I took the extraordinary step to ask Ofwat to investigate its licence conditions. I have demanded a serious recovery plan and swift action to prevent an incident like this happening again.”

Emma Reynolds continued: “This government has already banned unfair water boss bonuses, and our once-in-a-generation reforms will establish a new, single regulator with more teeth and greater powers to drive transparency including new MOT-style checks.”

Meanwhile the local MP Mike Martin said on Wednesday that a compensation fund for local businesses is set to be increased. Mike Martin met with the chief executive of the Water regulator OFWAT, Chris Walter, in Tunbridge Wells last Friday (see below).

South East Water’s compensation fund is currently only £600,000 despite evidence of an £18 million hit to the local economy.

Mike Martin said: “South East Water has now conceded what we’ve been saying for months – their paltry sum to local businesses barely touches the sides of the true financial damage inflicted on our local economy because of their water outage.”

Claims must be submitted to Wedlake Bell LLP, who are administering the process, using email sew@wedlakebell.com

South East Water’s Chief executive, David Hinton, said on Tuesday he was not taking any bonus for the 2025/2026 year. 

David Hinton said: “We are focused on delivering our long-term business plan, the most ambitious we have ever produced, designed to improve operational resilience while keeping customer bills affordable. Customers can be assured that we are working at pace to complete our full programme of works.”

In its latest update on Pembury Water Treatment Works on 9th April, South East Water stated: “Two new filters were installed to improve treatment processes, reduce the risk of water quality issues and increase the capacity of water that can be provided into the Tunbridge Wells system. These filters will allow South East Water to support the Pembury network from the Bewl water treatment works, providing an additional source of water to the Tunbridge Wells system, if needed. Additional operational improvements include revised site maintenance schedules, updated testing guidance for operators, and a revised inventory of critical spare equipment.”

Regulator’s Response to SE Water Failings is “Woeful”

A group of Tunbridge Wells residents has attacked the water industry regulator for not taking strong enough measures to secure water supplies in the town.

The water regulator OFWAT said on Thursday it planned to fine South East Water £22 million for supply disruptions in a period ending three years ago.

But local resident Jonathan Hawker (pictured below) of the group, Dry Wells Action, said: “We are extremely disappointed that there is no action to impose leadership on this company, or to force upon it a remedial action plan for urgent improvements and expansion of the infrastructure serving Tunbridge Wells.”

Jonathan Hawker continued: “This is great news for David Hinton (chief executive of South East Water). He will continue in post, with remuneration (including vast non-performance related bonuses) of £500k each year.”

Jonathan Hawker said OFWAT’s announcement highlighted “the shortcomings of the organisations that are supposed to be representing consumers’ interests.”

He said: “Hot off the tails of the public relations own goal by the Consumer Council for Water, which decided to sneak South East Water’s chief executive, David Hinton (pictured below), into Tunbridge Wells to be “held to account by consumers”, in order to launch their consumer panel initiative, without thinking how it would look to have no consumer from Tunbridge Wells present, OFWAT has now hit us with the news that its sole sanction on the failing water company will be a fine that we will end up paying.”

Jonathan Hawker stated: “Given that South East Water has £1.3bn in debt on a turnover of less than £300mn, from which it made a loss of almost £20mn last year, it should be obvious to OFWAT that consumers will end up paying this fine either through increases in water bills or through the additional cost of debt at the company.”

He concluded: “Hitting consumers who have already suffered is not regulation. It is an admission that the regulator has no means to hold this company to account. OFWAT’s announcement is woeful.”

The Liberal Democrat MP for Tunbridge Wells, Mike Martin (pictured below), told the BBC the OFWAT fine indicated a repeated failure by South East Water to learn lessons. But the MP said the penalty was “completely toothless.”

Mike Martin said: “When you’re looking at a company that’s a billion pounds in debt, they’re not worried about a £22 million fine. What we need is something that has bite. And I think really it’s only the government that can make the decisions to push OFWAT to impose things onto companies like South East Water…and cause them to change their behaviour.”

Mike Martin MP continued: “When Emma Reynolds, the Environment Secretary, actually came to Tunbridge Wells in January, she announced that she was writing to OFWAT and asking them to investigate whether South East Water had breached the terms of their licence. All these water companies need a water licence from the government in order to operate. So the government DOES have purchase on these water companies.”

Mike Martin believes that a decision that South East Water had breached its licence would allow a “special administrative regime” to be imposed to force through investment by the company.

Mike Martin discussed the failures at the Pembury Water Treatment works which led to 50,000 people losing their drinking water for two weeks in December (area affected shown above).

Mike Martin revealed: I’ve pulled together a group of water experts to assess what needs to be done at Pembury to bring it up to scratch. To get over the under-investment backlog that we’ve suffered from for the last 20 years, it’s about 50 million quid.”

Mike Martin argued: “If they’d spent that money and it (Pembury water works) hadn’t fallen over, they wouldn’t be paying fines. They wouldn’t be paying 30 million in compensation and operational costs when they have an outage. Local businesses wouldn’t be losing out.”

Mike Martin continued: “So if you put them into SAR (Special Administrative Regime), when they fail their licence, then you force through rapid investment and upscaling in pinch points like Pembury Water Treatment Works. That is what would fix this system. Water treatment works by water treatment works, storage reservoir by storage reservoir.”

Mike Martin concluded: “The government has to get a grip and get a hold of these companies.”

Meanwhile, water industry expert Charles Hedges (pictured below) told Southborough News he was waiting for a full report from the Drinking Water Inspectorate on last year’s failures at Pembury Water Treatment Works before commenting in detail.

Charles Hedges said: “South East water needs to do two things. First, provide a comprehensive chronological description of all that has gone wrong since 9th of November. And the next thing, they they need to show an organisation chart that demonstrates they’ve got the skills to undertake the engineering works to rectify all the mistakes.”

The Interim Chief Executive of OFWAT, Chris Walters, was asked by the BBC on Thursday why the regulator’s report on the 2020-2023 failures had taken three years to produce.

Chris Walters replied: “Investigations do take time, especially investigations like this, because they involve a large amount of very complex, detailed engineering information that has to be very carefully assessed…We knew that we had to be specific and careful and detailed. So we didn’t make any slip ups, and we can do the best for customers.”

Chris Walters also rejected the suggestion that customers will end up paying South East Water’s fine: “We are proposing a £22 million fine. Crucially, that’s a fine that is paid by the company and its investors, not customers. It won’t show up on customer bills.”

Chris Walters continued: “The enforcement audit will require South East Water to take concrete, specific, legally enforcible steps to do better….South East Water needs to step up and take more ownership of the problem. Take the specific steps in the action plan and work more constructively with us and with other regulators in future.”

OFWAT has opened a new investigation into South East Water’s failure to supply drinking water in December and January.

It’s also been revealed that South East Water attempted to use the courts to stop OFWAT from announcing its proposed fine, arguing that releasing the news would have a serious impact on the the company’s reputation and its credit rating.

A judge threw out South East Water’s interim injunction at a hearing in the High Court on Monday.

According to a report on the website Kent Online, South East Water claimed OFWAT had “predetermined” its findings and argued the regulator’s decision was “legally-flawed” and “riddled with errors”.

Nicholas Gibson, representing the company at the High Court, argued its shareholders “target strong investment grade credit ratings” and that maintaining those “has been – and continues to be – challenging.”

A statement presented to the court by South East Water’s chief financial officer, Andrew Farmer (pictured below), said: “I consider it very likely that publication of OFWAT’s legally flawed proposed decision, and therefore the detailed findings in the 240-page decision, would seriously damage confidence in South East Water among those working in the finance sector with…very serious adverse consequences for South East Water’s business.”

Mr Farmer added the company feared OFWAT’s report being published would lead to a potential “downgrade” to its credit rating and make it “much harder for South East Water to secure the additional financing which it requires.”

In his judgment, Mr Justice Chamberlain said, that given its provisional findings, OFWAT was under a “statutory duty to publish.”

The judge called the company’s attempt to block publication to protect the company’s reputation with investors and “keep the credit ratings agencies in the dark” as “objectionable in principle.”

The judge added blocking publication would create a situation where the company’s credit ratings were based on “materially incomplete information.”

He said this would mean “potential lenders might enter into contracts which they would not otherwise have entered into and existing investors might decide to retain their investments in circumstances where they would otherwise have exited.”

Mr Justice Chamberlain also dismissed the company’s “objectionable” plea that the company “should be allowed to control when and to whom the proposed decision is disclosed.”

A spokesperson for South East Water said: “We recently filed for judicial review of an OFWAT draft decision and sought an injunction. Following a hearing, the court did not grant the interim injunction. We respect the court’s decision on this.”

South East Water concluded: “We are now considering OFWAT’s draft decision and will respond via the appropriate channels, ahead of its final decision. We have no further comment at this time.”

Water Crisis: Public Meeting on Wednesday

A group of Tunbridge Wells residents has demanded that officials from South East Water and regulators meet the public at an event being held on Wednesday evening.

The group set up following prolonged failures of the local water supply is called “Dry Wells Action.”

Dry Wells Action’s founder, Jonathan Hawker (pictured below), wants measures to ensure the community is never again left unable to flush toilets or wash for days at a time.

Jonathan Hawker, said: “After all that it has been through, this community deserves to hear from the company itself and from those whose duty it is to hold South East Water to account. Not attending and speaking to people who’ve been so badly let down would in itself send a message of abject contempt for a community these organisations are meant to serve.”

Invitations were sent last week to the Water Minister, Emma Hardy MP; the three regulators – Ofwat, the Drinking Water Inspectorate, and the Consumer Council for Water, as well as elected bodies and members.

Dry Wells Action said on Monday that so far there are no indications that SE Water or regulators will attend. Mike Martin MP is also understood to be busy at Westminster.

But the meeting will go ahead to allow residents, councillors and outside experts to discuss why the community has experienced repeated, lengthy water outages and why regulators and government have not taken enforcement action against the company.

Dry Wells Action’s website states its demands are:

  • A fully independent engineering review of the entire water supply system serving Tunbridge Wells by an outside engineering consultancy, with an honest assessment of what is failing, what needs rebuilding and what it will cost.
  •  A funded plan with timelines with a clear list of upgrades, milestones, deadlines and published progress.  
  • Investment in a future-proof water infrastructure, not temporary firefighting. 
  • A change in leadership at South East Water and effective regulation.

Dry Wells Action is grateful to the owners of the Old Auction House in Tunbridge Wells which has made the venue available to the group for free to host the event. Access is free but limited. The meeting starts promptly at 7.30pm on Wednesday 21st January. Tickets are available via http://www.drywellsaction.com
