Bioretention
Generally located within a shallow surface depression, at or below the level of the adjacent surfaces being drained, bioretention systems are able to employ a wide variety of planting (including trees and shrubs) to create vegetation cover across the system. They are designed to intercept and treat surface water run-off, which is distributed across the whole system surface, as it vertically flows through the system structure.
