I started my PhD life the 1st November 2021.
Past and current water management practices will not meet future water needs. Water supply (pipelines) and wastewater treatment (sewage plants) infrastructures are ageing and need to be upgraded. In addition, raw material scarcity, water stress, population growth, climate change and biodiversity erosion pose new challenges.
Decentralised urban water management to promote the circular economy (reuse of treated water) and make cities more resilient to climate change through Nature-based Solutions (NBS) appears to be an interesting alternative. NBS are actions or infrastructures that protect, restore and sustainably manage ecosystems to mimic and optimise natural processes, while promoting biodiversity and ensuring human well-being.
One NBS for wastewater treatment that is widespread in France is planted filters, constructed wetlands designed to exploit natural processes to improve water quality.
My subject concerns the elimination of microorganism (virus, bacteria, protozoa, etc), that are harmful for humans, by a planted filter (wetland) for reusing the treated water in urban area.
