Written question WQ83927

There are tight regulatory controls over the number and volume of discharges from Combined Storm Overflows (CSOs) located near coastal bathing waters. They are only permitted to discharge when the sewer network has reached capacity due to heavy rainfall and where there is a risk of sewage backing up into properties. Natural Resources Wales (NRW) and Dŵr Cymru Welsh Water (DCWW) have identified and reduced the spill frequency of all storm overflows which could affect designated bathing water sites.

In 2021, and for the fourth consecutive year, Wales met 100% bathing water quality compliance standards, with 85 of the 105 designated bathing waters achieving a classification of ‘excellent’ and none were classified as ‘poor.’ The classification is based on the results of a statutory monitoring regime delivered by NRW pre and during the bathing season which runs from 15 May until 30 September.

Wales is internationally recognised as having some of the best beaches and best water quality in Europe. High bathing water quality makes a significant contribution to coastal tourism, the Welsh economy and local communities. High bathing water quality is also vital for supporting valuable outdoor water recreation opportunities and contribute to the wellbeing of our citizens.
