Abstract
Urbanisation has created many issues in Australian environments (Skwirk, 2005). Urban stormwater increases flash flooding and affects water chemistry by changing levels of heavy metals and nutrients such as nitrogen and phosphorus (Morse et al., 2003). Water Sensitive Urban Design (WSUD) was introduced as a stormwater management strategy that has evolved in response to increasing urban development and decreasing water quality. The general aim of WSUD is to protect and improve the health of waterways by imitating the natural water cycle as closely as possible (Melbourne Water, 2015). There are a range of stormwater treatment devices used under WSUD; these include gross pollutant traps (GPTs), bioretention systems for streetscapes, swales and buffer strips, sedimentation basins and constructed wetlands (DPLG, 2010). This project evaluated the effectiveness of a new type of WSUD treatment device, the Floating Treatment Wetland (FTW). FTWs are described as as cultivated plants growing on floating mats in open water, which can be used to remove pollutants from runoff (Wang et al., 2015). The purpose of this study was to evaluate the effectiveness of the FTW in treating the urban runoff from the development site at Bribie Lakes, Bribie Island. The project entailed the collection of water samples from the FTW to enable the treatment efficiency to be evaluated. The water samples were delivered to the USC NATA accredited laboratory and analysed by Analytical Chemists, as well as, by the project investigator. The three main parameters which the study focused on were total suspended solids (TSS), total nitrogen (TN) and (TP) total phosphorus.
