Our focus on high-quality blue-green infrastructure relates to the overarching principle that surface water runoff should be managed for maximum benefit for people and nature. We follow the principles of CIRIA’s four pillars of SuDS, as outlined in their SuDS manual.
Control runoff to manage flood risk and maintain and protect the natural water cycle.
Manage the quality of the runoff to prevent pollution.
Create and sustain better places for people.
