Flooding poses a very real risk to housing developers and the land occupied. Building houses, roads, and paved areas on previously natural, permeable ground fundamentally changes how the land can manage water, ultimately leading to potential flooding both on site and further downstream. Here, we discuss the importance of incorporating an effective sustainable drainage system (SuDS) into new build developments, helping to protect the site for years to come.
With an increasingly unpredictable climate bringing extensive dry periods followed by spells of intense rainfall, drainage systems can become overwhelmed with the vast amount of water flowing through, leading to localised flooding. Manging this flow is critical to reducing the flood risk and keep properties, and their occupants safe.
Investing in Sustainable Drainage Systems
The pressure to incorporate SuDS into new build developments is mounting from local planning authorities, requiring evidence of the surface water management strategy being implemented. Similarly, developers are also feeling the pressure to incorporate natural habitats within each site to meet biodiversity net gain requirements.
Dealing with excess surface water takes more than traditional drainage and as managing water at source is now considered essential, measures must be put in place to meet these expectations.
Below-ground attenuation solutions, such as Wavin AquaCell, provide a practical way to store excess rainfall and release back into the system at a controlled rate. This helps to capture and hold large volumes of water during intense rainfall to reduce the chance of flooding, while maximising space on-site, delivering effective below-ground surface water management without compromising on site layout.
Building to Last
House buyers not only want a property that delivers their aesthetic vision; they need the reassurance that their home has been built to last.
While many may not be aware of the importance of SuDS or attenuation systems, demonstrating that these solutions have been incorporated into a development creates a powerful point of difference. Showcasing a robust, future-ready drainage strategy instils buyer confidence and reassurance that the property and surrounding area is designed to perform, even in challenging weather conditions.
Moving Towards Smarter Water Management
Modern attenuation solutions have evolved over the years to meet the changing needs of developers. Modular systems such as Wavin AquaCell NG deliver high-capacity storage alongside design flexibility, allowing developers to adapt to site-specific requirements, handle intense rainfall, integrate with treatment solutions, and importantly, implement future-proof designs to withstand changing climate conditions.
Traditional drainage solutions are no longer adequate to meet the rising demands of today’s challenging weather. Only by incorporating a complete surface water management system can new developments truly withstand the full force of nature.
As planning frameworks evolve, attenuation systems must be seen as a priority to capture, treat, store, and reuse excess surface water that could otherwise lead to flooding. This not only supports compliance but helps to create safer, more resilient places to live, meeting the demands of modern construction.
