When it comes to sustainable drainage systems (SuDS), many sites present unique challenges that demand more than standard solutions. While the basics such as permeable paving, soakaways, and swales are essential for managing runoff and improving water quality, complex sites often require a more advanced approach. Here, we explore some cutting-edge SuDS features that can help overcome the obstacles posed by difficult ground conditions, limited space, or strict regulatory requi

For architects and housing developers, understanding Standard Four of the National SuDS Standards is essential for delivering compliant, sustainable, and marketable projects. This standard is all about water quality and ensuring that runoff from your developments is treated effectively before leaving the site. Why Water Treatment Matters for Your Projects Modern developments face increasing scrutiny over environmental impact. Urban runoff carries oils, silt, and debris that c

Permeable pavements are increasingly used in sustainable drainage systems (SuDS) to manage rainwater, reduce surface runoff, and meet planning and environmental regulations. Knowing when a permeable pavement design is compliant is essential for successful project delivery. Here is a detailed explanation of the main compliance rules, including practical scenarios and design tips. Permeable Surfaces Without Additional Drainage When a permeable pavement only receives rainfall th
