Sustainable Drainage Systems

The Council encourages the use of Sustainable Urban Drainage Systems (SuDS) to manage surface water in a sustainable way.

SuDS in new developments

From April 2015 sustainable drainage is a material consideration in planning decisions. Therefore, the Local Planning Authority in consultation with the Lead Local Flood Authority (LLFA) will:

  • ensure that SuDS are used in major developments unless it is demonstrated that they are inappropriate
  • ensure that the minimum standards of operation proposed by the applicant are appropriate
  • ensure through the use of planning conditions or planning obligations that there are clear arrangements in place for ongoing maintenance of the SuDS scheme over the lifetime of the development

In all applications for major 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. Note that SUDS are also encouraged with all other applications in line with planning policy.

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.
