How can we improve the new SuDS Manual?

CIRIA is currently updating the 2007 SuDS Manual (C697). This involves collating and assessing recent science, guidance and evidence and taking into consideration recent and emerging legislation and local policies. As part of this project we are seeking your feedback on how the new SuDS Manual can be improved.


Update of the SuDS Manual

We would be grateful if you could provide us with the following:

  • Feedback required on content, layout and usability based on current SuDS Manual.
  • Comments required on each chapter of existing SuDS Manual.
  • Your opinion on where additional sections might be of use in the new document.

Case study request for update of the SuDS Manual

We would also be grateful if you could provide us with case studies and examples of SuDS in practice, either installed or in the planning and design stages.

Your feedback will be of great help in determining how we take the updated Manual forward and we appreciate any input you can share with us.


The closing date for both questionnaires has been extended to Monday 29 July 13.
