The Sustainable Development Goal indicator 6.2.1 calls for safely managed sanitation systems that protect health at all steps of the sanitation chain. Moving towards a sustainable circular economy requires us to rethink the role and reuse of wastewater, greywater and faecal sludge.

Sanitation Safety Planning (SSP) is a newly-launched World Health Organization tool, which helps optimize reuse of wastewater, greywater and excreta in low-income countries, ensuring the increasing reuse of wastewater is safe. The approach takes into account all relevant stakeholders from the entire sanitation service chain, and uses a health-based risk assessment to better manage and finance improved sanitation.
