Overview
The project investigated whether updating the current non-statutory technical standards could help provide for multiple benefit Sustainable Drainage Systems, and if so, what those updates might 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 would 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
Department for Environment, Food and Rural Affairs (Defra) will use this research to inform its drainage policy development.
