The aim of this project was to investigate whether updating the current Non-Statutory Technical Standards could help provide for multiple benefit SuDS, and if so, what those updates should be. Based on the findings, recommendations are made to replace the current standards 1 to 6 with a new suite of standards. The new standards cover the following:
- Standard 1: Runoff destinations
- Standard 2: Everyday rainfall
- Standard 3: Extreme rainfall
- Standard 4: Water quality
- Standard 5: Amenity
- Standard 6: Biodiversity
Defra will use this research to inform its drainage policy development.
This research was delivered by HR Wallingford Ltd and sub-contractors (CIRIA, Illman Young, McCloy Consulting, Coleman Planning & Environmental, Balfour Beatty).
