From April 2015 sustainable drainage is a material consideration in planning decisions.

In all applications for development, developers or applicants must include a statement outlining the proposed Sustainable Drainage System to be incorporated in the development, along with details for their long term management and maintenance.
The SuDS guidance document(pdf, 1364KB) provides advice to developers, applicants, designers, householders and others on how to incorporate SUDS within new developments of all types and sizes.
