Constructed Wetlands for Wastewater Treatment in Hot and Arid Climates,
Springer Cham, part of the book series: Wetlands: Ecology, Conservation and Management (WECM, volume 7), 2022.15 Oct 2022. Nelson M., Cattin F., Tocchetto D., Hafouda L.; chapter N° 20/21 "Wastewater Gardens Systems in Yucatan, Mexico; Northwest Australia; Northern Algeria and Southern Iraq", an overview and follow-up of systems built by our team in Mexico, Australia, Algeria and upcoming southern Irak. From the publisher: "This edited book presents the first collection of case studies and research projects on the sustainable technology of constructed wetlands for wastewater management under hot and arid climates. It is the first such work that summarizes in a single reference the current international experiences and knowledge on the implementation of this nature-based solution under these diverse and often harsh climatic conditions. It covers the relevant gap in the fragmented and limited literature by providing integrated information and documentation on the feasibility of this green technology. The book presents the treatment efficiency of constructed wetland facilities and the research output from 29 different countries across South America, Africa, Asia and Oceania, while it covers various applications such as domestic and municipal wastewater, various industrial effluents and municipal sludge. Many examples and case studies further demonstrate the potential of  this technology to contribute to better address the issues of water scarcity and limited fresh water resources through circular management of treated effluents e.g. reuse in irrigation. ... (It) demonstrates the sustainable character and benefits wetland technology can bring to low-income regions with hot/dry climates. ...".

*Due to reasons outside of our control, some errors feature on the technical specifications given on the wetland which served as the basis for this study; they however don't have any impact on the experimental results presented. For instance the system built has a 0% slope inside the system; 2.5 plants minimum per m2 (square meter) with roughly 1/3 deep rooted, 1/3 medium and 1/3 light rooted (as initially planted; it doesn't mean that it is maintained that way) - about 10% of these plants can be and were chosen in this case as test plants, meaning they may not survive initial plantation and must be replaced if they die ; adapted plant species diversity can be significantly further increased.
