Sustainable Development Goal (SDG) 6 seeks to improve water quality by decreasing the amount of untreated wastewater and increasing recycling and safe reuse of wastewater globally. To effectively monitor progress towards this goal, government buy-in and robust data gathering and monitoring are crucial.
The project aims to develop, pilot test, and validate a monitoring methodology for SDG target 6.3. The resulting tool, called the Wastewater Reuse Effectiveness Index (WREI), seeks to facilitate governance processes by providing scientific results that are useful for policymaking. WREI also recognises the interconnections between a range of sectors and environmental resources, and so gathers holistic data to better meet the needs of decision-makers at global, regional, and national levels.
This project is a joint effort between UNU and UN-HABITAT, custodian agency for SDG target 6.3. The WREI tool is endorsed by 11 countries and supported by two regional consultation workshops. Other initiative partners include the Ministry of Construction, Government of Vietnam; Arab Countries Water Utilities Association (ACWUA), Jordan; University of Minho, Portugal; Livelihoods and Natural Resources Management Institute, India; Institute of Global Environmental Strategies (IGES), Japan; and University of Sao Paulo, Brazil.
