Reusing resources is a central dimension of the Sustainable Development Goals (SDGs). This can be seen, for example, in the emphasis on wastewater use in SDG 6 (“Ensure availability and sustainable management of water and sanitation for all”), and Target 6.3 in particular.
The Wastewater Reuse Effectiveness Index (WREI) has been developed to encourage wastewater use in line with SDG Target 6.3, and to monitor countries’ abilities to meet this target.
At the 2017 Arab Water Week in Amman, Jordan, the UNU Institute for Integrated Management of Material Fluxes and of Resources (UNU-FLORES), together with the UN Human Settlements Programme (UN-Habitat) and the Arab Countries Water Utilities Association (ACWUA), organised a pilot testing and validation workshop on this new monitoring methodology.
The two-day workshop (22–23 March) discussed the challenges of effective wastewater monitoring, and sought feedback on the WREI prototype methodology. On Day 1, participants discussed key issues and opportunities with regard to monitoring SDG Target 6.3, the choice of indicators for an index, and lessons emerging from development of the WREI prototype in Brazil and Indonesia. Day 2 of the workshop was devoted to discussing the potential of key capacity development opportunities and, cognizant of the need to build robust national systems as a precursor to establishing a global monitoring system, the role of national and regional universities, research and training institutes, and think tanks.
