Following our successful installation of two floating wetlands for Blacktown City Council (at Blacktown International Sports Centre and at William Lawson Wetland) we were commissioned to design and install a new floating wetland at Ropes Crossing.
The water quality in the stormwater pond was clearly being affected by sediment and nutrient runoff from the developing urban catchment. We were asked to design a floating wetlands solution to mitigate these issues in an ecologically sound fashion.
The floating wetland we installed is 168m2 within a 5000m2 pond. We installed 3 x 56m2 rectangle floating wetlands parallel to one another, positioned to intercept the flow of stormwater flowing through the pond.
We did not install our bird protection cage because there are not many waterfowl apart from a few brown ducks. However, we did mitigate the risk of bird predation by installing our pre-planted coir mats, which we planted 18 months ago. These mats are the ideal way to colonise the floating wetland with the bacteria and microorganisms required to the establish the wetland processes on the constructed floating wetland.
