New Water Treatment System
Published on by Water Network Research, Official research team of The Water Network in Technology
A NEW floating wetland water treatment system at a Bli Bli subdivision will be the subject of a four-year research project
The floating water treatment system at Parklakes II is the first time such a system has been used on a greenfield development of such size.
The system will involve the installation of 230 "living" pontoons to filter man-made lakes which will tackle the stormwater from 436 residential lots, a school, and a 226 unit retirement village in the subdivision.
Doctor Chris Walker, environmental manager of engineering consultancy Covey and Associates said the living pontoons would be planted with reeds which would draw sediment and nutrients from the water through their roots.
The pontoons will eventually cover 2100sq m of a 2.5ha lake, one of three in the subdivision.
The first two of the pontoons were launched on Wednesday at a function attended by representatives from the Sunshine Coast Council, the University of the Sunshine Coast, and Parklakes II developers and contractors.
A PhD student will study the efficiency of the floating wetlands system over the next four years in collaboration with the University of the Sunshine Coast.
Dr Walker said the FWTS had been installed in existing catchments but the Parklakes II installation offered an opportunity to truly test it.
"The new FWTS approach has huge potential and we have been working with USC over the past five years to optimise the system and to develop a strong research partnership that ensures research results are independently verified," Dr Walker said.
