Guidance SUSTAINABLE DRAINAGE SYSTEMS: NON-STATUTORY TECHNICAL STANDARDS Non-statutory technical standards for the design, maintenance and operation of sustainable drainage systems to drain
surface water. Get emails about this page DOCUMENTS NON-STATUTORY TECHNICAL STANDARDS FOR SUSTAINABLE DRAINAGE SYSTEMS Ref: PB14308 PDF, 46.8 KB, 4 pages DETAILS This document contains
non-statutory technical standards for the design, maintenance and operation of sustainable drainage systems. Systems to drain surface water from housing, non-residential or mixed use
developments for the lifetime of the developments. Sustainable drainage systems slow the rate of surface water run-off and improve infiltration, by mimicking natural drainage in both rural
and urban areas. This reduces the risk of “flash-flooding” which occurs when rainwater rapidly flows into the public sewerage and drainage systems. In December 2014, DCLG set out the changes
to the planning system that will help to increase the use of the sustainable drainage systems. This document should be used in conjunction with the National Planning Policy Framework and
Planning Practice Guidance. UPDATES TO THIS PAGE Published 23 March 2015 SIGN UP FOR EMAILS OR PRINT THIS PAGE Get emails about this page Print this page
