Abstract

This guidance outlines best practice for using sustainable drainage systems (SuDS) to reduce phosphorus in surface water runoff from new developments. It explains how SuDS components can be combined in treatment trains to achieve effective phosphorus removal, particularly for sensitive water bodies and protected habitats. The document provides design principles, performance data, and worked examples aligned with nutrient neutrality requirements, highlighting infiltration, sedimentation, and vegetative uptake as key mechanisms. It also addresses regulatory context, design constraints, and maintenance considerations to ensure long-term effectiveness.
