New Guidance on the Construction of SuDS

CIRIA launches new guidance to support successful SuDS construction and delivery.

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 due to the additional benefits they can deliver for urban places including; improved air and water quality, greater biodiversity and reduced noise. As a result of this 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.

CIRIA’s latest guidance document, Guidance on the construction of SuDS (C768) has been created to support and provide greater confidences to those designing, specifying and constructing 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.
The updated guidance on the construction of SuDS (C768) is collaboratively funded and free to download from the CIRIA website at
