Simple terms explainer

Councils ensure that new developments include sustainable drainage systems (SuDS). SuDS are designed to manage rainwater in a way that mimics natural drainage, helping to reduce the risk of flooding, improve water quality, and support biodiversity. This means that when planning applications are reviewed, councils must check that developers have included appropriate drainage solutions - like permeable surfaces, swales, or retention ponds - that slow down and treat runoff before it reaches rivers or sewers. It’s a key part of making communities more resilient to climate change and protecting the local environment.
