Nature’s Water Treatment: Floating Wetlands


Floating wetlands are not only among the most productive ecosystems, they also naturally remove pollutants, trap sediment, and improve water quality. Is it possible to mimic this biological treatment process in the urban setting? How can the combination of man-made technology and natural systems provide a platform for nature to take over stormwater treatment?

Join Australian researcher Andy Hornbuckle for a live and on-demand webinar exploring the principles by which floating wetlands treat stormwater and sewage, as well as the design, validation, and application of floating wetlands for stormwater treatment and storage. A hot spot for nutrient and sediment mitigation, we’ll learn how floating wetlands are a resilient solution to improve water quality, and carry minimal capital expenditures and operating expenses.

We’ll kick off this online training webinar with an overview of the history and application of floating wetlands. Next, we’ll examine how floating wetlands use a combination of man-made technology and natural systems to biomimic natural floating islands. This biomimicry creates a concentrated wetland effect, or a complex, living ecosystem that enables the capture and removal of nutrients (nitrogen, phosphorous), as well as fine and coarse sediments including clay, metals, algae, and other toxins from both point and non-source pollutant loadings. We’ll then jump into the design and manufacturing of floating wetlands and the design constraints that need to be considered to ensure maximum treatment efficiency. Referencing field research to date and implementation of floating treatment wetlands in Australia throughout the webinar (e.g. detention basins with floating wetlands), Hornbuckle will describe: how floating wetlands can be custom designed to suit project constraints; different ways to successfully install, anchor, and maintain them; how flow-weighted field research has been successfully conducted and applied to subsequent projects; and the design, validation, and assessment of floating wetlands throughout case study development. Before wrapping up, we’ll take a look at illustrations of floating wetlands in stormwater, as well as examine modifications to cope with the dry season, variable velocities, and hydraulic grades within residential and urban development. Within this examination, we’ll explore how floating wetlands are a sustainable solution to turbidity issues, wind and wave action, and habitat decline. We’ll conclude with a discussion of the costs and suggestions for next steps.
