It is important to treat pathogens in stormwater and wastewater before release into downstream recreational waters or harvesting. Using plants in water treatment improves the removal of pollutants of concern to human and ecosystem health. However, the exact mechanisms which generate this improvement remain unknown, and this is especially true for faecal pathogen removal. This project will enhance our understanding of the interactive role that roots, their exudates, plant debris and soil microbes play in faecal pathogen removal in urban water treatment systems. Through this understanding, this project will lead to optimised low-energy, low-tech and low-maintenance treatment systems.

在释放到下游娱乐水域或收获之前，必须先处理雨水和废水中的病原体。在水处理中使用植物可以改善对人类和生态系统健康有影响的污染物的去除。然而，产生这种改善的确切机制仍不清楚，尤其是在清除粪便病原体方面。这个项目将加深我们对根部、其分泌物、植物残渣和土壤微生物在城市水处理系统中清除粪便病原体方面所起的相互作用的理解。通过这一理解，该项目将导致优化的低能源、低技术和低维护的处理系统。
