The recent rainy weather is a reminder of the vital importance of managing urban water runoff effectively. In the face of climate change and urbanisation, Sustainable Urban Drainage Systems (SuDS) offer robust solutions for managing stormwater runoff and maintaining the health of our environment.

So, what are the wider benefits of a well-designed SuDS strategy?

The most obvious advantage is its ability to mitigate the risks associated with flooding. By incorporating techniques like green roofs, permeable pavements, and rain gardens, SuDS systems can reduce the burden on traditional drainage infrastructure.

Consequently, this helps prevent overwhelming of stormwater systems during heavy rainfall events. SuDS features also aid in filtering pollutants and improving water quality by capturing and treating runoff, reducing the flow of harmful substances into rivers and streams.

A well-designed SuDS strategy not only benefits the built environment, but also provides opportunities for enhancing biodiversity and promoting ecosystem services. For example, our SuDS strategy for the former Lambeth Hospital took a landscape-led approach, incorporating: a planted, dry detention basin; a system of swales; permeable paving and a surface water storage feature. This delivered a 77% improvement in terms of the rate of surface water runoff from the site compared to the existing case.

Features like wetlands, bioswales, and vegetated areas within SuDS strategies can help create habitats for a variety of plant and animal species, providing a platform to enhance biodiversity and support the ecological balance of the surrounding areas. Moreover, SuDS strategies align with sustainable development goals by promoting water conservation, reducing energy consumption associated with traditional drainage systems, and enhancing urban resilience.

Another benefit of an effective SuDS strategy is the transformation of urban spaces into greener, more sustainable environments. This can offer recreational opportunities, improve air quality and contribute to the overall well-being of local communities. These strategies contribute to creating more liveable and environmentally-conscious spaces.

The opportunities provided by well-thought-out Sustainable Drainage Systems (SuDS) are far-reaching. Embracing and implementing SuDS practices is a step towards building a sustainable future for generations to come.
