The new SuDS Manual is free to download from both Susdrain and the CIRIA website. Much has changed since the last Manual was produced in 2007; knowledge, experience and delivery have improved both in terms of quantity and for the most part quality.
The new manual contains considerably more information, several new sections, 300+ images and dozens of case studies and, with full colour and a reader navigation system based on readers’ needs, it is easier to use.
So what’s changed? At its core the SuDS manual recognises SuDS is an opportunity and should (wherever possible) deliver multiple benefits for schemes. Surface water runoff is not really a problem, it’s a resource, this complements CIRIA’s BeST (Benefits of SuDS tool) project. The manual also asserts the notion that with effective and early engagement of the right team SuDS can be delivered on any site, often cost effectively delivering more than just local flood risk management.
The new Manual suggests that SuDS isn’t just for engineers, it’s also a design process with landscape architects and urban designers playing an important role (as do communities in retrofit situations). The best schemes are likely to be those that have engineers and landscape architects working side-by-side with an appreciation of what the different disciplines can provide to get the best out of a site.
