The systems commonly used include bioretention basins, raingardens, kerbside bioretention pits, and bioretention swales. Stormwater is directed to these systems via piped systems or overland with breaks in kerbs or swales directing water to enter the treatment system. Treated stormwater is collected at the base of the system via perforated pipeswhich are located in a gravel drainage layer. The treated stormwater is discharged to the local waterways or collected for reuse. Figure 1 below shows a concept illustration of a raingarden or bioretention tree pit illustrating stormwater flow pathways and subsurface infrastructure requiring maintenance.
