Slum Sanitation Program (SSP) was conceptualized with the objective of improving health and hygiene conditions of slums in Mumbai through better sanitation services. The approach to build only demand based community toilets and active involvement of the community based organization for maintenance demonstrated consistent achievement of objectives resulting in Reduction of open defecation and improved health and hygiene conditions. The implementation of “ONLY WOMEN” community organization demonstrated accrual of other social benefits. The Program through its approach over years has demonstrated its sustainability and potential to be deployed in other cities of India. The program has deployed various innovative technical solutions viz. Bio Digester, Bio Culture, incinerator and solar panel to overcome hurdles in providing sustainable sanitation services in remote and geographically impossible slums. The use of GIS based platform has enhanced transparency and cleanliness. The program emphasizes success of mission, Swatch Bharat Mission, if rightly implemented.
