Background: A lack of safe water, sanitation and hygiene (WASH) is particularly a problem in India, which is responsible for the majority of world’s open defecation. The Government of India’s response to the country’s WASH challenges, which includes campaigns focused on improving sanitation coverage, has been inadequate. To fill the gaps of the government-led sanitation campaigns, Gram Vikas, a nonprofit organization in Odisha, India developed the Movement and Action Network for Transformation of Rural Areas (MANTRA) program. MANTRA facilitates the establishment of a community-wide water distribution system that provides household-level piped water that is contingent on full village-level toilet coverage.

Methods: This cost analysis used a prospective costing approach to enumerate intervention inputs, estimate base year costs from a broad societal perspective, and extrapolate intervention costs over a 10-year time period, with 2015 as the base year. Costs were incurred or constructed, in the costing model, on three levels – the program implementer (i.e., Gram Vikas), village and household. The fixed capital and recurring costs for each of the three levels were summed together per year and discounted to 2015 using a 3% discount rate. The discounted, per annum costs were totaled to determine the total cost of MANTRA over the 10-year period and allocated per household based on the number of households projected to participate in the intervention during the 10-year analytical period. Data were collected from village and household level surveys, which were supplemented with inputs from Gram Vikas collected through an enumeration exercise, interviews and by examining Gram Vikas’ financial records. 

Findings: The total cost of the MANTRA program over the 10-year analytical period was approximately $1,240 per household. The fixed capital cost of the village water system ($327 per household) and the household sanitary unit ($747 per household) accounted for the majority (85%) of the total cost. Approximately 30% of the household sanitary unit fixed capital cost was attributed to unpaid labor contributed by the household members. The Government of India played a major role in reimbursing the cost of the village water system and providing households with an incentive ($180) for their sanitary unit.
