Investigation launched into Dŵr Cymru sewage spills

An investigation has been launched into Dŵr Cymru (Welsh Water) after the company admitted illegally spilling untreated sewage.

Natural Resources Wales said it was examining the severity and frequency of permit breaches by the water company.

Welsh Water said between 40 and 50 of its wastewater treatment plants are currently operating in breach of their permits after being shown data by an environmental campaigner.

Analysis by Professor Peter Hammond, from campaign group Windrush Against Sewage Pollution, showed the worst offender is the Cardigan plant in west Wales, which spilled untreated sewage on 1,146 days from the start of 2018 to the end of May 2023.

The plant discharges into the River Teifi, which flows into Cardigan Bay – the home of Europe’s largest population of bottlenose dolphins.

Prof Hammond’s analysis of data over a five-year period showed there were 2,274 days when untreated sewage was released in breach of a permit.

Water treatment works are allowed to discharge untreated sewage in order to ensure it does not become overwhelmed during heavy rain, but this overflow level is regulated by permit.

Welsh Water said it plans to build a new £20 million water treatment works for Cardigan as part of a £40 million package in the county.

Compliance issues

Ann Weedy, operations manager at Natural Resources Wales, said: “We are aware of significant compliance issues at the Cardigan wastewater treatment works, and we have used our regulatory powers to enforce the improvements required at the site over the years.

“The issue is now unresolvable without significant investment and upgrading of infrastructure by Welsh Water. But this is the kind of investment that we and the public expect.

“The enforcement action we are taking at this site requires Welsh Water to commit to this programme of work during their next investment period and we will work with them to drive the improvements at this site that we all want to see.

“We are currently investigating the severity and frequencies of the permit breaches at the site and this investigation is ongoing.”

A Welsh Water spokeswoman said: “We have a longstanding record of being open and transparent in relation to our environmental performance.

“We have applied this approach to compliance with our treatment works permits and have always raised any areas of non-compliance with our regulator, Natural Resources Wales, as soon as they are identified.

“We have extensive monitoring arrangements, amongst the most extensive in the sector, which we use to monitor our sites.

“Each site presents its own and sometimes very complex challenges, with NRW reviewing the information we provide, agreeing appropriate timescales for resolving the issues, and taking enforcement action where appropriate.

“We always aim to resolve any issues as quickly as possible, to limit any impact for both the environment and our customers.”

Review

Politicians are calling for a review of Welsh Water and called for tougher action against sewage dumping.

Plaid Cymru spokesperson for climate change, Delyth Jewell MS said: “This is a damning admission from Dŵr Cymru, which raises serious questions, both for them and for NRW – not only because of the sheer number of wastewater treatment plants that have been releasing untreated sewage, but also because it appears both Dŵr Cymru and Natural Resources Wales have known this was happening for nearly a decade.

“This is hugely concerning for our natural environment. Untreated sewage can lead to a myriad of problems for our rivers and the ecosystems they support. Urgent answers are needed to explain why Dŵr Cymru has not faced penalties for these ongoing failures and why this situation has persisted for almost a decade without decisive action.

“It is also crucial that the Welsh Government exercises all the constitutional powers at its disposal to strengthen our environmental governance arrangements over water. Through our Co-operation Agreement with the Welsh Government, Plaid Cymru has secured a commitment for legislation in this regard.”

Janet Finch-Saunders, the Welsh Conservative shadow climate change minister, said: “For this to be described as the worst sewage works in terms of illegal discharges shows how Labour has dropped the ball on sewage in Wales.

“Welsh Water has broken the law and must face the consequences.

“At a time when Welsh Water are planning to increase bills, even though their customers experience the second highest average bill in Wales and England, is completely unacceptable when they have been misleading the public for years and dumping harmful sewage into our waterways.

“The Labour Government need to follow the lead of the UK Government and start holding this disgraceful dumping to account by fining and start prosecuting Welsh Water, their inaction is harming our environment and waterways.”

Jane Dodds, a Liberal Democrat MS, added: “This is a shocking admission and the Welsh Government can no longer dodge the issue,” she said.

“We have the second highest bills across the whole of England and Wales, company bosses have been awarded thousands in bonuses and at the same time have been illegally dumping sewage into our rivers.

“I have repeatedly led calls in the Senedd for tougher action on sewage dumping and for a full review of Dwr Cymru and its operation.

“The Welsh Labour Government must take those calls seriously or risk the future of our rivers.”

This is absolutely shameful for a water company that charges one of the highest rates in the UK. What the hell are they doing with our money? An investigation is needed and quickly. Companies in all lines of business, including councils, are paying themselves so much money in salaries, pensions and bonuses they have no money left for the service they are meant to provide. The government and auditors need to step in and dismiss the top management of these companies as they are clearly not competent for the job they are employed to do. However, they all seem to… Read more »
