The time to sort it all out is now. Efforts to improve wastewater treatment are gaining momentum. The Sustainable Development Goals (SDGs) are likely to address the lack of treatment around the globe (up to 90 percent of wastewater in developing countries does not undergo treatment.) Current targets under the SDGs
call for halving the proportion of wastewater that goes untreated worldwide. As the SDG process is finalized and as we ready the 2016 version of the EPI report, we are looking to you to help us refine the signal we send policymakers.
We have created an interactive map
that visualizes our metrics on wastewater treatment performance: the percentage of wastewater that receives at least primary treatment, the percentage of the population connected, each country’s final wastewater treatment score (the product of these two percentages), and the source of each country’s data.
We are asking you to check out your country — or any country you may be familiar with. Does the data and the score seem consistent with your experiences or your knowledge? Is it somehow incomplete? Do you think the data source is valid or problematic? Could you point us in the direction of better or more recent sources of data, or tell us how we can improve?
We want to hear from you! With your help, we can enhance our understanding of wastewater treatment efforts, an important part of encouraging sustainable development around the globe.
