Adoptable Sustainable Drainage Systems (SUDS) now included in Sewers for Scotland 2nd Edition.

WRc has just published the much anticipated 2nd Edition of Sewers for Scotland (SfS2), the technical guide for developers laying sewerage infrastructure that is to be vested in (adopted by) Scottish Water. Unlike its sister document Sewers for Adoption, which applies in England and Wales, SfS2 now contains detailed guidance on the Sustainable Drainage Systems (SUDS) that can now be vested because of changes to Scottish Legislation. As such SfS2 is breaking new ground in public surface water management requirements.

Scottish Water will now vest detention ponds, basins and underground storage structures designed to attenuate surface water runoff before it enters watercourses or sewers. Scottish Water has no responsibility for SUDS within property boundaries and consequently the vested public SUDS will have to be located in public open space. SfS2 provides detailed design guidance on pond and basin configuration & dimensions, size, location, inlet and outlet structures, water quality, operation and maintenance, safety, amenity, and ecology, and design guidance for underground storage.

It is the first time a UK Sewerage undertaker has set-out comprehensive requirements for the construction of public SUDS. SfS2 explains Scottish Water’s specific requirements and consequently it will be of interest to all SUDS practitioners.

SfS2 can be purchased through the WRc Water and Environment Bookshop www.webookshop.com
