Sustainable Drainage Systems (SuDS) are designed to manage surface water runoff in a way that mimics natural drainage processes. They help reduce flooding, improve water quality, and enhance biodiversity by using features like ponds, swales, and permeable pavements. SuDS aim to slow down and filter rainwater, allowing it to soak into the ground rather than overwhelming traditional drainage systems. These systems are increasingly important in urban areas where impermeable surfaces, such as roads and buildings, prevent water from naturally soaking into the soil. By integrating green infrastructure and natural features, SuDS contribute to healthier ecosystems and more resilient communities, making them a vital part of modern urban planning.
