Welsh Water has been fined £90,000 for repeatedly breaching environmental regulations by polluting the River Wye near Hereford. The Environment Agency took legal action after routine tests showed the company violated permit conditions multiple times over ten months.
Incident Details
Effluent Breaches and Timeline
Between August 2020 and June 2021, Welsh Water failed to comply with its environmental permit conditions at the Kingstone and Madley sewage treatment works. The permit required that biochemical oxygen demand (BOD) levels not exceed 7 milligrams per litre on more than two occasions in a 12-month period. However, routine sampling detected three violations:
- 8 August 2020: BOD levels reached 13 milligrams per litre.
- 19 May 2021: BOD levels spiked to 74 milligrams per litre.
- 19 June 2021: BOD levels were recorded at 41 milligrams per litre.
These results indicate severe operational failures at the treatment works, significantly impacting the river’s ecosystem.
Court Proceedings
At Worcester Crown Court on 7 June, Welsh Water pled guilty to the charges. The court imposed a £90,000 fine and ordered the company to pay £14,085.05 in costs and a £190 surcharge. The court heard that the Environment Agency was alerted to the issue following routine sampling results in July 2021.
The Agency argued that the persistent high levels of pollutants indicated poor operational management and inadequate asset provision by Welsh Water.
Environmental Impact
The elevated BOD levels suggest that the sewage treatment works were performing poorly, leading to significant environmental damage. Biochemical oxygen demand measures the amount of oxygen required by microorganisms to break down organic matter in water.
High BOD levels can deplete oxygen in water bodies, harming aquatic life and disrupting the ecosystem.
Statements from Officials
Adam Shipp, a senior environment officer at the Environment Agency, stated:
“Incidents like this are preventable and are completely unacceptable. Water companies are aware that their activities have the potential for serious environmental impacts, and they know that we will take action when they cause pollution.”
Company Response
In its defense, Welsh Water cited challenges in identifying the root cause of the breaches for the first two incidents. The company attributed the third breach to a significant storm event. However, the court found these explanations insufficient, highlighting the need for better management and infrastructure.
Regulatory Perspective
The Environment Agency has been vigilant in monitoring water companies to prevent pollution. Welsh Water’s environmental record over the past decade has shown a worrying trend of increasing pollution incidents.
In 2022, the company caused 89 sewage pollution incidents, with 5 classified as having a significant environmental impact. Additionally, Welsh Water accounted for over 25% of all sewage discharges in Wales and England in 2022, releasing sewage into waterways for nearly 600,000 hours.

In Conclusion
Welsh Water’s £90,000 fine for polluting the River Wye underscores the company’s ongoing struggle with environmental compliance. Despite significant investments in infrastructure, Welsh Water has failed to prevent repeated pollution incidents, leading to severe ecological damage.
This case highlights the importance of stringent environmental regulations and proactive measures to protect our natural resources.
For water companies, maintaining robust operational standards and investing in sustainable practices are crucial steps towards safeguarding the environment for future generations.
