CIRIA guidance
CIRIA has produced a number of guidance documents covering a range of opportunities and challenges related to general water management, all the way through to specific SuDS components. The more notable publications are CIRIA C753 The SuDS Manual and CIRIA C713 Retrofitting for surface water management. The majority of publications are below, some are free to download.
Sustainable drainage
Using SuDS to reduce nitrogen in surface water runoff (C815F) (FREE)
2023. This new guidance is intended for those developments affected by nutrient neutrality rulings. It outlines the design criteria for a good SuDS scheme that can maximise the opportunity to capture and remove nitrogen. It also describes the difficulties of capturing nitrogen, as it is present in different forms, and the many different processes to do so.

Using SuDS to reduce phosphorus in surface water runoff (C808F) (FREE)
2023. This new publication provides good practice guidance on the use of SuDS for the reduction of phosphorus in runoff from new developments. It sets out the necessary SuDS, deployed in ‘treatment trains’ to achieve phosphorus reduction, particularly for sensitive receiving waters and nationally important nature conservation sites. It represents good practice surface water management through the use of SuDS and can be applied anywhere.

Surface water management
The natural flood management manual (C802F) (FREE)
