Preamble added to clarify purpose of Adoption Guidelines for Stormwater Biofiltration Systems

The research and development of biofilter technology over the last 15 years has facilitated the widespread adoption in policy and implementation of biofiltration for stormwater quality improvement.

It has helped seed industry growth with a number of innovative variations to, and adaptation of, the biofiltration system being configured and tested.

So as to not unintentionally restrict ongoing industry innovation in this technology, the following preamble has been incorporated into the inside cover of the recently published Adoption Guidelines for Stormwater Biofiltration Systems to clearly articulate their purpose.

“These guidelines are based on extensive testing and development of biofiltration system designs that use readily sourced soil-based filter media and mainly Australian native plants. Other biofiltration systems with alternative design specifications to those listed in these guidelines can also be considered as effective stormwater treatment systems, provided they have been demonstrated under realistic conditions to achieve an acceptable pollutant removal and operational performance.”
