Bioretention and biofiltration was first pioneered over a decade ago in the US as part of the Low Impact Development (LID) movement. Conventional Bioretention systems were larger, landscaped drainage systems, developed as means not only of dealing with the quantity of stormwater from developments, but also filtering runoff through an aerobic plant, soil and microbe complex to capture, remove and cycle pollutants.
Often the most sustainable and practical drainage techniques are those which engineer in nature’s way – combining the best of natural processes with simple and elegant technological solutions.
Have you ever noticed a wasted opportunity in the islands, trees and plants at the side of our roads and car parks…..?
