SuDS - Flood Management Solutions

SuDS Legislation The Flood and Water Management Act (2010) was introduced to provide comprehensive flood risk management for people, homes and businesses. Schedule 3 of the Act outlines a framework for the approval and adoption of drainage systems, including standards for the design, construction, operation and maintenance of SuDS; it is expected to become mandatory by late 2024.

The Impact All new commercial and residential developments must deliver sustainable drainage, with approval from the Local Planning Authority required prior to commencement. These requirements will be strengthened and SuDS Approval Bodies (SABs) will ensure developers meet National Standards. They may deny connections to public sewers if the requisite criteria are not met.

Regulatory Requirements

The SuDS requirements focus on four pillars: Water Attenuation, Water Quality, Biodiversity and Amenity. Sustainable drainage systems should control surface flow rates and volumes, manage the quality of runoff to prevent pollution, create and maintain better habitats for nature and create and sustain better places for people. Planning authorities and SABs will ensure that all new developments fulfil these pillars.

The Biodiversity Advantage It's important to note that as of April 2024, all new developments must provide at least 10% more biodiversity than before and sustainable drainage systems can contribute to this outcome.
