HAYWARDS BAY CONSTRUCTED WETLANDS

摘要

Four hectares of wetlands were incorporated into the overall urban design of Wollongong's newest suburb, Haywards Bay, which comprises 400 homes and a commercial precinct overlooking Lake IllawarrarnThe wetlands were designed to drain freely into the groundwater table. This unconventional interaction between surface and groundwater was designed to increase the supply of freshwater to the endangered saltmarsh community on the foreshore of Lake Illawarra.rnDuring the design, nitrogen migration modelling and possible bio-accumulation of toxic sediments was conducted and suitable measures incorporated. Detailed water quality and biological monitoring programs are to be conducted over a significantly longer term than conventional monitoring.
