We are working with water companies and wider partners to drive forward long-term solutions. Following the recent water Price Review determination, Dŵr Cymru Welsh Water (DCWW) will invest £6 billion in Wales between 2025-30, including more than £1.2 billion to reduce harm from storm overflows and prevent nutrient pollution. In the meantime, the mandatory requirement for sustainable drainage systems (SuDS) on almost all new developments is helping to alleviate pressure on the storm overflow network.
