A Global Estimate of Sewerage Connections Without Treatment
The Joint Monitoring Programme (JMP) definition of improved sanitation does not yet account for sewage treatment. In Environmental Science & Technology, we developed an empirical model to reassess the water and Millennium Development Goal (MDG) sanitation target. Our study shows that 1.5 billion people use sewage connections without treatment, highlighting the need to include sewage treatment as an indicator in the post-2015 Sustainable Development Goals (SDGs) to account for public health and environmental protection in assessing sanitation.
