What is the status of wastewater treatment performance at the national level?

We’d like your help!

In 2014, the Yale Center for Environmental Law & Policy created a first-of-kind indicator on national-level wastewater treatment. We devoted a ton of resources and staff time to sifting through a wide variety of data sources, but we know it was just a start. A new interactive map will crowdsource your feedback to help us refine and improve this important indicator of both ecosystem and human health.  

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.
