2 The SuDS solution CIRIA’s early and intuitive belief that sustainable drainage systems (SuDS) make a positive contribution to surface water management (SWM) and the built environment has been demonstrated repeatedly through their successful delivery. This has been supported by publication of the first SuDS manual (C697) in 2007 and more recently the susdrain initiative www.susdrain.org. Access to CIRIA outputs on SuDS-related guidance has seen the delivery of increased numbers of high-quality SuDS, improved methodologies, planning, design and other approaches as well as increased knowledge and research in the area over the ensuing eight years. This edition of Evolution celebrates the 2015 launch of the updated SuDS manual (C753), and the release of the Benefits of SuDS Tool (BeST), designed to evaluate and quantify the multiple benefits of SuDS. ‘Evolution’ is an appropriate word to use in context of a discussion about how SuDS have gained momentum since 2007 and from the early 1990s when CIRIA first investigated the concept. Suzanne Simmons, CIRIA Project Manager spoke to the chair of the SuDS manual update project steering group, Professor David Balmforth (DB), ICE President, its lead author Bridget Woods-Ballard (BWB), HR Wallingford, Dr Christopher Digman (CD), MWH Global, and lead author for BeST, Brian Smith (BS) of Yorkshire Water and Brian Morrow (BM) of United Utilities provided a wider water company perspective. Long before the Pitt Review of 2007, CIRIA has been providing industry guidance, training as well as thought leadership within this area. In recognition of the interdisciplinary nature of SuDS as well as increased knowledge and research, the SuDS manual has been updated to incorporate the latest technical advice and adaptable processes to assist in the planning, design, construction, management and maintenance of good SuDS. The need to support partnership funding and retrofitting by quantifying the benefits of SuDS has formed the basis for the production of BeST which will be used to compare and assess different SWM approaches for a diverse range of impacts. Importantly, both the SuDS manual and BeST are independent of legislation. The SuDS manual will have a wide audience and has been aimed at several levels of user knowledge, whilst BeST specifically focuses on the designer, planner and developer as the end user. WATER Suzanne Simmons, CIRIA Project Manager, discusses the role of sustainable drainage systems (SuDS) in surface water management and the built environment ahead of the issue of the SuDS manual (C753) and Benefits of SuDS Tool (BeST) “The launch of the CIRIA SuDS manual in 2007 meant that for the first time drainage designers could go to one place to find the technical support they needed to get SuDS in the ground. And the result was that many new developments became the home to SuDS for the first time, to the benefit of their owners and occupiers, and society in general". David Balmforth, ICE President
