National Standards for Sustainable Drainage

 

Non-statutory technical standards have been produced by Defra for England and the Welsh Government for Wales. There’s an expectation that SuDS will be designed and constructed in accordance with these standards that are also consistent with the SuDS Manual. A number of local authorities have produced their own policy and guidance, the Local Planning Authority should be contracted with regards to their local requirements at the earliest opportunity.
