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. We are working with water companies and regulators to develop a programme of work for CSOs

The Welsh Government collaborated with the water industry, regulators and UK and devolved Governments via the 21st Century Drainage Programme, to improve long-term planning for drainage and wastewater management. The programme secured agreement on a framework for Drainage and Wastewater Management Plans (DWMPs), which includes technical guidance, evidence gathering and collaboration. This will form the basis for DWMPs being put on a statutory footing in Wales.

As a first step, water companies in Wales are preparing DWMPs on a non-statutory basis. These will be published for public consultation in 2022 .They will help identify where investment should be prioritised from 2025, and the best method to do this.

The Programme for Government commits us to improving inland waters and strengthening river water quality monitoring. We need to consider all pressures on our waters and are adopting a collaborative multi-sector approach to secure sustainable solutions which deliver not only the water quality improvements we need but also positive outcomes on biodiversity, net zero and climate adaptation.
