Water Sensitive Urban Design 6.4 Filter Media Specifications The Facility for Advancing Water Biofiltration (FAWB), a joint collaboration between Monash University and Ecological Engineering Holdings recently updated the original filter media specifications produced in 2006. Specifications are given for the three main layers defined for a bioretention basin as described in the table below. Further details relating to the testing of hydraulic conductivity, the specific filter media specifications (for example, organic matter content, pH, electrical conductivity and phosphorus content), and particle size distribution can be found in the FAWB document Guidelines For Soil Filter Media In Bioretention Systems (version 2.01). http://www.clearwater.asn. au/resources/658_1.FAWB%20Filter%20 media%20guidelines_revised_March%20 2008.pdf Recently, bioretention basin design has evolved to include an anoxic zone. In 2008, FAWB conducted a series of workshops on biofiltration systems, which included the design requirements and performance of biofiltration systems with submerged zones. The workshop material made the following specifications: 1. Depth of submerged zone – approximately 450 mm. 2. Media specifications – sand or gravel, containing a carbon source such as hardwood chips or sugar cane. The carbon source is to account for 5 percent of the volume of the submerged zone media. The workshop manual produced by FAWB can be downloaded from the following url: h t t p: // w w w.m o n a s h.e d u.au/ f a w b/ products/index.html Filter Media (typically 400 to 600 millimetres in depth) Loamy sand, with an appropriate hydraulic conductivity (100 to 300 millimetres per hour) and soil properties given in AS4419 – 2003 (Soils for Landscaping and Garden Use) Drainage Layer (typically 150 millimetres in depth) Clean, well graded sand / coarse sand material (containing no/little fines) Transition Layer (typically 100 millimetres in depth, or sufficient to provide 50 millimetres of cover to drainage network) Clean fine gravel 48 <strong>Book</strong> 4 | MAINTENANCE
