Sanitation in large and dense villages of India: the last mile and beyond

The aim of this white paper is to explore the nuances of the prevalence of on-site sanitation systems in large and dense villages of India. Villages which have a population of 1000 persons or more and a density of greater than or equal to 400 persons per square kilometre were classified as large and dense villages in an earlier research – Towards a New Research and Policy Paradigm: An Analysis of the Sanitation Situation in Large Dense Villages. Stimulated by the findings revealing a preferential pattern for selection of on-site sanitation systems in these settlements, a primary household survey was conducted in large and dense villages from five Indian states - Himachal Pradesh, Punjab, West Bengal, Madhya Pradesh and Tamil Nadu. The survey also included qualitative components – stakeholder interviews and transect walks. In this study the survey data has been canvassed to explore the preference patterns of households and the factors guiding them in their decision making for the construction and maintenance of on-site sanitation systems. We find that these large and dense villages exhibit a higher preference for septic tanks over pits in all states except West Bengal where pits are preferred. A majority of households have reported their toilets were private constructions. We find the preference patterns are manifested not only by the choices of building septic tanks or pits but also through the large variations in their design and sizes which are influenced by socio-economic, technical and behavioural factors. We also find specific trends in demand for desludging services by households which are influenced by internal factors such as their social status and economic well-being and by external factors such as availability of mechanised operators or continued reliance on manual cleaning and their costs which cumulatively constitute the supply side of sanitation services.
