Clarity Aquatic partnered with Unitywater and Covey Associates to conduct a leading-edge constructed floating wetlands (CFW) trial and pilot study at Kenilworth Sewage Treatment Plant in South East Queensland. The trial demonstrated how CFWs can be used as a sustainable low- technology approach to enhance treatment capacity of existing infrastructure and reduce the amount of nutrient discharged from the treatment plant.

This trial investigated the performance of a range of plant species and the results demonstrated some of the most significant plant growth and pollution removal rates of any floating wetland project we have worked on. Unitywater was awarded AWA Queensland’s Infrastructure Project Innovation Award (Servicing over 250,000 end users) for this pilot study in 2019.

We look forward to our continued collaboration with Unitywater and Covey Associates to further investigate and develop nature-based solutions in sewage treatment.
