Do you have a view on updating the Non-Statutory Technical Standards for SuDS?

The Department for Environment, Food and Rural Affairs (Defra) has commissioned research to explore whether updating the English Non-Statutory Technical Standards for SuDs (NSTS) could help deliver SuDS that provide multiple benefits beyond managing surface water runoff, contributing to improved climate adaptation, health and wellbeing and better places and spaces.

A key part of this work is to understand, through a survey how the current NSTS are used, and to recommend how they could be improved to manage local flood risk and deliver multiple benefits. The survey should be completed by those with an interest in SuDS delivery, particularly those who approve, design and commission SuDS for new developments in England.

The NSTS are a fundamental set of guidance which Metis use when designing and reviewing SuDS proposals and we will be submitting a response. It would be very valuable if you could please also complete the survey here:


Survey responses will be used to inform recommendations for any potential update of the NSTS and may support England’s future approach to SuDS delivery. The survey should, depending on your level of involvement in SuDS delivery, take between 20 and 30 minutes to complete.

The closing date for the survey is 22 June 2020.
