Welsh Liberal Democrats Condemn Dŵr Cymru’s Water Bill Rise for Swansea Households

The Welsh Liberal Democrats have criticised plans by Dŵr Cymru Welsh Water to raise household water bills by 5% from April, warning that families across Gwyr Abertawe and Swansea Bay are being asked to pay more while pollution, sewage dumping and service failures continue to blight local waterways.

Under the new plans, customers of Dŵr Cymru will face an average annual bill of £683, an increase of £31 a year. While slightly below the highest rises elsewhere, the increase comes during an ongoing cost-of-living crisis and will hit households already struggling with rising food, energy and housing costs.

The announcement will anger residents across Swansea Bay who have repeatedly raised concerns about sewage pollution affecting rivers, beaches and coastal waters. Communities have seen waterways treated as dumping grounds, with regular discharges undermining tourism, public health and confidence in the water system.

Despite this, customers are now being told to pay more, while the wider system continues to fail both households and the environment.

The Welsh Liberal Democrats argue that families should not be forced to bankroll years of under-investment and environmental damage. They say the current regulatory framework is too weak, allowing water companies to raise bills without delivering the scale of improvement that customers rightly expect.

The party is calling for fundamental reform of water regulation in Wales, including replacing Ofwat with a new, powerful Welsh regulator that puts customers and the environment first. Welsh Liberal Democrats also support moving toward a mutual ownership model, ensuring that money paid by customers is reinvested into infrastructure, sewage treatment and environmental protection, rather than extracted as profit.

“Asking families in Gwyr Abertawe to pay higher water bills while sewage continues to be dumped into our rivers and coastal waters is simply unacceptable. People are already struggling with the cost of living, yet they’re being told to pay more for a system that clearly isn’t working.”

“Our beaches and waterways are central to Swansea’s economy, environment and quality of life. Continued pollution damages tourism, harms wildlife and undermines public trust and households should not be footing the bill for these failures.”

“The Welsh Liberal Democrats believe the current system is broken. We need more than minor tweaks, we need a regulator with real teeth that will put customers and the environment first, not protect water companies from accountability.”

“We also believe water should be run in the public interest. A mutual ownership model would ensure that money paid by customers is invested back into cleaning up our waterways and maintaining infrastructure, rather than disappearing elsewhere.”

“Water is a basic necessity, not a luxury. People in Swansea deserve a system that delivers clean rivers, reliable services and fair bills, not rising costs alongside declining standards.”
