Individual raft size is 1.2 x 1.0 m. The NativeAwa Floating Wetland Rafts are robust and feature a unique dog-bone hinging system, which allows for overall flexibility, accommodates water movement and enables each project to be custom-made to suit specific requirements.

Developed and manufactured by experts, NativeAwa’s Floating Wetland system is also aesthetically pleasing and can be used in ponds (including effluent ponds), treatment plants (stormwater and wastewater) and small lakes.

Benefits of NativeAwa’s Floating Wetlands:

  • High-density planting increases nitrate uptake and provides a support habitat for microorganisms that break down waste products (nitrates, fine sediments, metals and pollutants) in our ponds.
  • The large custom-made surface area creates a large surface area for the microbes to attach to.
  • Nature does all the work in the floating wetland plant growth, however NativeAwa’s Floating Wetland rafts provide a robust support system for plant growth as well as a habitat for bird and fish life.
  • The rafts provide erosion and sediment control.
  • NativeAwa’s artifical floating wetlands system is easily adapted to suit the particular environmental requirements.
  • NativeAwa’s system is environmentally conscious, using no resins or polystyrenes.  They are manufactured locally. The compact raft size reduces transport requirements – approximately 700 rafts fit into one truck and trailer unit, reducing the carbon footprint.

Over time, a natural ecosystem evolves providing a sustainable solution that requires minimal maintenance.

Besides accelerated settlement of sediment from influent wastewaters, floating treatment wetlands have several other treatment benefits.  The wetlands can result in a significant reduction (up to 99%) in faecal coliform load, the BOD load (up to 75% reduction) and ammonia.  Provided that conditions in influent wastewater allow, conversion of ammonia species to nitrate species occurs beneath the wetland, and nitrate species are then converted by denitrifying bacteria within the root mass.  As a result, up to 75% of nitrogen removal can be achieved.  Accelerated settlement of sediment also contributes to removal of phosphorus and metals loads within the wastewater. Further, the sludge volume is typically significantly less than in conventional pond systems due to the microbial digestion of organic solids that occurs in the settled warm conditions beneath the wetland.
