Ateb
Atebwyd gan Minister for Climate Change
The Welsh Government does not, itself, hold evidence on storm overflows and sewage pollution in Wales. This evidence is held by Natural Resources Wales (NRW), and Wales’ two water companies, Dŵr Cymru Welsh Water (DCWW) and Hafren Dyfrdwy. A number of third parties, including non-governmental organisations and community groups may hold relevant information also.
Both DCWW and Hafren Dyfrdwy have installed event duration monitoring (EDM) equipment on their storm overflow assets, which captures information on the duration and location of storm overflows. EDM data is publicly available online at Combined storm overflows | Dŵr Cymru Welsh Water (dwrcymru.com) and Documents | Regulatory Library | HD Cymru.
Information about water quality classification can be found on the NRW website at Natural Resources Wales / Improving water quality.
