A colleague and I are collecting examples of stormwater mitigation installations that have been around for at least five years. We are trying to find out if they continue to function well and continue to look good enough to please the public. 

The vertical walls based on hydroponics are fundamentally unsustainable.They rely on constant monitoring by humans, they are artificial lige supporting systems unless they are fully emulating conditions that exist in nature which is rare. Unless a system is developed that invites spontaneous colonisation by plants – like porous sponge ceramics or…[Read more]
