WELSH WATER: £44.7m sewage package confirmed — but critics say it is too little, too late
A multi-million-pound package forcing Welsh Water to put right years of sewage failures has been formally confirmed — but critics say it has come far too late for the rivers and beaches already paying the price.
The water regulator Ofwat has accepted a £44.7m enforcement package from Dwr Cymru Welsh Water, after finding “serious and unacceptable breaches” in how it ran its sewage network.
The package was first proposed by the company in March and has now been signed off following a public consultation.
For one Welsh MP, the confirmation was less a cause for celebration than an indictment of how long the problems were allowed to go on.
David Chadwick MP, the Welsh Liberal Democrats’ Westminster spokesperson, said the findings confirmed what communities across Wales had known for years.
“Welsh Water has been failing to do its job while rivers, streams and coastlines have paid the price,” he said.
He said people would be “rightly furious” that it had taken intervention from Ofwat and a £44.7m package to force action on failings he argued should have been addressed years ago.
Chadwick took aim at the company’s not-for-profit model, arguing it had still overseen serious wastewater failures while paying out large executive bonuses.
He said his party would keep pushing for stronger regulation, backed by properly resourced enforcement, to hold polluters to account and protect rivers.
Ofwat’s investigation found the company had failed to properly operate, maintain and upgrade its wastewater network, and lacked adequate oversight from senior bosses.
Of the total, £40.6m will go towards reducing spills at specific overflows and tackling groundwater getting into the sewer network, with a further £4.1m to improve river quality in what the regulator called “extremely sensitive catchments”.
The regulator said the package was larger than the £40m fine that would otherwise have been imposed, and stressed it would be funded by the company rather than added to customer bills.
Lynn Parker, Ofwat’s senior director for enforcement, said the investigation had found serious breaches that resulted in excessive spills to the environment.
She said that with the investigation now concluded, the company was expected to focus on putting things right so customers could regain trust in it.
The confirmation lands at the end of a punishing run of headlines for the company across the Swansea Bay News area.
Only last week, the First Minister ordered an investigation into the River Tawe after Senedd members raised reports of people falling ill after contact with the water.
Last month, campaigners rallied at Caswell Bay on Gower as part of a national day of action, after data revealed the company’s worst decade for pollution.
In Pembrokeshire, an MP demanded answers from Welsh Water after a boy was hospitalised following a swim in the sea off Tenby.
The company points to a separate report, published the same day, setting out record levels of investment.
It said it spent £617m on its water and wastewater network in 2025-26, including £134m on environmental improvements and £85m on cutting leaks.
Chief executive Roch Cheroux acknowledged the company had not delivered the level of service customers expected, particularly on environmental performance.
“That is why we are investing at record levels to improve resilience, strengthen ageing infrastructure and deliver more reliable services, while keeping bills as affordable as possible,” he said.
He said the company was also listening carefully to customers and communities so that its future plans reflected the issues that mattered most to them, pointing to a major engagement programme running across Wales this summer.
Jane Hanson CBE, chair of parent company Glas Cymru, said the firm had “focused relentlessly on building the foundations needed to deliver sustained improvements” over the past year.
She said its 2025-30 business plan was the most ambitious in the company’s history, with £6bn of total spending planned, but accepted there was “still a significant amount of work ahead”.
Those bills, however, are still going up. Welsh Water customers saw their charges rise by 4.8% in April, taking the average annual bill from £652 to £683.
The company says it provides financial support through social tariffs to around 150,000 customers, and is trying to lift its environmental rating from two stars to three.
Whether that turnaround convinces a public weary of sewage warnings and rising bills is, for now, an open question.
