Jason Rogers
Head of Water Quality and Environment
We all share a strong commitment to the environment and our local communities, so I’d like to take a moment to reflect on all the efforts underway to make our rivers healthier and keep our natural spaces thriving.
There’s plenty to be happy about, but let’s be honest – the job isn’t finished yet, and there’s still a lot we can do together.
Today represents a meaningful step forward as Natural Resources Wales (NRW) has published our Event Duration Monitoring (EDM) data. These results, shared openly, provide tangible insights into the frequency of our storm overflow activations.
We recognise just how vital it is for you to have confidence in our work, and although we are seeing improvements in the rivers, streams, and communities we all cherish, we know there is always room to do better.
Reflecting on our early achievements
We’re encouraged by some of the achievements so far. Since Hafren Dyfrdwy’s inception in 2018, we have not experienced a single serious pollution incident, which is a positive sign. In addition, we have successfully reduced average spill counts from 36.2 in 2024 to 21.6 in 2025, reflecting our ongoing commitment to cleaner waterways.
We’ve also averaged 2.5 Category 3 pollution incidents per year from our sewerage assets; while Category 3 refers to minor, short-term incidents, we remain determined to reduce this figure even further. Our ambition is to reach zero by 2030, but we are under no illusion – this will require continued effort, vigilance, and collaboration to truly safeguard our local rivers and natural spaces for everyone.
As we entered our new five-year business cycle, we have set out an ambitious investment plan to improve both our wastewater and water distribution systems. Alongside this, we are refining our approach to identifying and addressing the root causes of pollution, recognising that prevention is key and that ongoing improvement is essential.
Our first Pollution Incident Reduction Plan
Our Pollution Incident Reduction Plan (PIRP), which is available for all to view online, underpins our work. I am pleased to present our first PIRP for Hafren Dyfrdwy, highlighting the positive steps we are taking to lessen our environmental impact. However, the publication of our EDM data and PIRP is not the end of the story – it is a moment to reflect honestly on our progress and, most importantly, on the challenges that remain. We are committed to learning and evolving as we continue this journey of innovation and environmental stewardship.
Together, we are making strides towards a greener, cleaner, and more resilient region, but we know we must keep pushing forward. We are determined to meet – and where possible, exceed – the standards you rightly expect and deserve. Protecting our environment is a shared responsibility, and we are committed to working tirelessly, every day, to do better for nature, our communities and future generations.
