This solution caters to local governments that have the mandate to manage stormwater in a city. It addresses the management of rainfall and runoff from public open spaces and transport infrastructure. The management of runoff from residential, commercial and institutional buildings are covered in a separate Solution as a different approach is required for areas under private ownership.
The solution promotes the creation and enhancement of permeable surfaces, waterscapes and networks of open drainage channels and watercourses which slow down runoff and maximize infiltration and treatment by natural processes.
Aiming to collect, treat and infiltrate as much water as possible from public open spaces and transport infrastructure by the use of Sustainable Drainage Systems (SUDS), namely a combination of drains, swales, vegetated trenches, retention basins, wetland systems, multiple use green spaces, etc., this solution has benefits at multiple levels.
