Managing Non-Sewered Sanitation for Achieving Sustainable Development Goal 6 in India

Abstract

The challenge of ensuring clean water and safely managed sanitation towards meeting the Sustainable Development Goal 6 is made more complex by unplanned urbanisation in South Asia. Nearly 50% of all toilet-owning households globally and 83% in South Asia depend on non-networked sanitation, with a multi-step service chain comprising containment, collection, conveyance, and treatment of faecal waste. Over the last few years, South Asian governments have begun to eschew the long-enduring preference for centralised sewerage infrastructure in favour of better management of non-networked sanitation as part of city-level wastewater management systems. However, these interventions have largely excluded the household-level containment systems that hold the potential to create both adverse localised and diffuse public health and environmental outcomes if dysfunctional. The present Chapter discusses evidence from a multi-state household survey in India to assess the nature and quality of containment systems in use by urban Indian households. Secondly, it reviews approaches to their governance under more evolved paradigms to inform an ecosystem-wide strategy for managing these systems in India and countries with similar contexts.
