On Nov. 12, CIRIA, the construction industry research and information association, launched sustainable urban drainage systems (SuDS) guidance. The updated SuDS Manual (C753) covers the cost-effective planning, design, construction, operation, and maintenance of SuDS. The updated SuDS Manual is collaboratively funded and is free to download from the CIRIA website.

Earlier this year, the Secretary of State for Communities and Local Government stated that SuDS must play a greater role in the UK’s planning system. SuDS are now required in new major developments wherever appropriate.

The guide is designed to help communities use SuDS in a way that recognizes the value of rainwater by capturing, using, delaying, or absorbing it. Sustainable drainage delivers multiple benefits. It helps communities cope better with severe rainfall and improves quality of life by making urban spaces more vibrant, sustainable, and resilient to climate change.

CIRIA first published The SuDS Manual in 2007. However, authors significantly revised this guidance. The updated manual incorporates new research, industry practice, and guidance. The new manual helps readers meet the government’s non-statutory technical standards for SuDS but goes further to support the cost-effective delivery of multiple benefits.
