Recommendations to Update Non-Statutory Technical Standards for Sustainable Drainage Systems (SuDS) - WT15122
The aim of this research project is to report whether updating the current Non-Statutory Technical Standards (NSTS) could help provide for multiple benefit sustainable drainage systems (SuDS), and if so, what those updates should be. Based on the findings from this research, recommendations have been made to replace the current standards 1 to 6 with a new suite of six 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
Each standard is accompanied by a set of clarifications that provide guidelines to support the interpretation, delivery and evaluation of the standard.
This report has two parts:
Part 1 – Project Report – This describes the objectives of the project, the technical approach, the research findings and recommendations.
Part 2 – Updated Standards – This presents six new standards that are proposed to replace the existing standards 1 to 6 in the current NSTS for SuDS.
This report is also accompanied by eight separate annexes.
