Abstract

Civil Engineering

constructed floating wetlands

stormwater pollution

nutrient removal

sampling protocol

This paper presents the results of an ongoing investigation into the pollution removal performance of a Constructed Floating Wetland (CFW) receiving stormwater runoff from an urban residential catchment on Bribie Island, Australia. Bribie Island is dominated by a sandy substrate, with high hydraulic conductivity. The CFW (101 m2) was sized at approximately 0.14% of a contributing catchment area of 7.46 ha. The study found that TSS and TP outflow concentrations were significantly (p<0.05) reduced after CFW treatment. However, the reduction in TN was not significant. It is believed that this was due to very low and highly variable inflow concentrations at the test site.
