Environmental guidance for your business in Northern Ireland & Scotland

Sustainable Drainage Systems (SuDS)

Sustainable drainage systems (SuDS) can be used in all types of development to provide a natural approach to managing drainage.

SuDS prevent water pollution and flooding in urban areas. SuDS also create green spaces and habitat for wildlife in towns and cities.

SuDS are a legal requirement for all new developments in Scotland, except for surface water drainage from single dwellings and developments that drain to coastal waters.

This guide describes the different types of SuDS, and how and when you must use them on your site.
