CIRIA’s ‘susdrain’ community of practice brings together professionals involved in all aspects of surface water management, from sustainable drainage systems and natural flood management to blue-green infrastructure and nature based solutions. With over forty organisations represented, the susdrain community meets regularly and promotes good practice through knowledge sharing, communication and collaboration. Member subscriptions allow susdrain to host free webinars on a range of relevant topics and events such as the SuDS Awards and this year’s SuDS Champions Awards. The susdrain website www.susdrain.org is an independent website sharing guidance, information, case studies, videos and blogs, much of its content is supplied by our members.
