Investigation into the long-term stormwater pollution removal efficiency of bioretention systems

Water Sci Technol. 2017 Oct;76(7-8):2133-2139. doi: 10.2166/wst.2017.382.


In recent years, there has been a steady increase in the number of bioretention systems installed worldwide. However, there has only been limited research on the long-term effectiveness of these sustainable urban drainage system devices. This paper presents the results of a series of controlled field experiments investigating the pollutant removal efficiency of three, 10-year-old, bio-filtration systems that have been in service in the Sunshine Coast in Australia. The results of this study suggest that the long-term pollution removal performance of these systems may not be as effective as previously thought and further research is needed.
