Abstract:
This report aims 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 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. Broad findings and trends emerging from the survey were discussed in details in the report – Sanitation in Large and Dense Villages of India: The Last Mile and Beyond. In this report we discuss targeted questions on the preference patterns for on-site containment systems that 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 deviations from prescribed design and 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.

Abstract:
As per the National Sample Survey 2018, nearly 60% of urban India relies on On-Site Sanitation (OSS) systems, like septic tanks and leaching pits, for the management of faecal waste. Augmentation of toilet access over the last five years under the Swachh Bharat Mission has only served to entrench this dependence, despite a push for centralized sewerage systems underwritten by schemes like AMRUT in Class I cities during the same period. Notwithstanding their scale and criticality to public health outcomes, OSS systems are poorly regulated and consequently ill-constructed in India. Therefore, it is vital to address the deficiencies in the downstream sanitation service chain beyond the toilet – beginning with the OSS system - to ensure that India meets its targets toward providing ‘Safely Managed Sanitation Services’ under the Sustainable Development Goal 6. The present study is a novel attempt to systematically analyse the state of OSS in urban India through a sample survey of 3000 households and more than 50 key informant-interviews across ten cities in four states. It shows that septic tanks, confused in common parlance and practice for a septic tank system, comprise the majority of all OSS systems at over 90%. However, in meeting household-level preferences, these systems exhibit variations along each of the principal design parameters, which cumulatively result in less than 2% of all surveyed septic tanks meeting the major requirements of the national governing standards. It finds OSS fraught with several compelling needs, including the inefficacy of septic tanks as primary treatment units, the lack of secondary treatment and safe disposal of pathogenic effluent, their delayed maintenance, and the lack of greywater management. In systematically identifying these issues, the report also recommends interventions in design, planning, and governance for safer and more sustainable on-site sanitation.
