Guidance on the construction of SuDS (C768)

This new report from CIRIA, developed with part-funding from the NHBC Foundation, provides practical support for those designing, specifying and constructing Sustainable Drainage Systems (SuDS).  It is available free of charge from CIRIA at

Managing flood risk continues to be a key priority for Government and in the draft London Environment Strategy, released earlier this autumn, the Mayor encouraged the use of sustainable drainage systems as a way to manage surface water (and deliver additional benefits for urban places, including improved air and water quality, greater biodiversity and reduced noise). As a result of this initiative and increased funding for water management across the country, we can expect to see a rise in the number of SuDS schemes being delivered in coming years.

Summary of content

The new CIRIA guidance has been created to support and provide greater confidence to those designing, specifying and constructing Sustainable Drainage Systems (SuDS) by helping them to understand and avoid common pitfalls experienced through the delivery process. The guide complements CIRIA’s SuDS Manual (C753), published in 2015, and provides clear, practical advice, diagrams, case studies, checklists and photographs to illustrate challenges faced on site, as well as providing information on correct installation methods and work stages.
