How is the Welsh Government holding water companies accountable for inaccurate real-time water pollution data?
Ateb
Atebwyd gan Cabinet Secretary for Climate Change and Rural Affairs
Both Dŵr Cymru Welsh Water (DCWW) and Hafren Dyfrdwy (HD) have installed Event Duration Monitoring (EDM) on more than 99.5% of their relevant storm overflow assets and have recently unveiled storm overflow maps providing near real-time information on storm overflow activity across Wales.
When DCWW first launched its real-time map on 1 February 2024, they started with the assets closest to bathing waters and within 1km of swim locations, as well as shellfish waters. DCWW are incrementally adding more assets and all 2,300 of their overflow assets will be live with near real-time information by March 2025. The map is available on DCWW’s website at: Storm overflow map | Dŵr Cymru Welsh Water (dwrcymru.com). Hafren Dyfrdwy’s map is also available online at Storm Overflow Map | In My Area | HD Cymru.
Welsh Government will continue to work closely with both water companies through the Better River Quality Taskforce to ensure the data is robust and accurate.
