Findings from the Demon of Defeca
Some 70% of urban India's sewage is untreated. Learn how our research shaped a campaign to counter this health risk.

Vast amounts of India's sewage goes untreated, presenting a major health hazard.
Yet our research showed that some 78% of people believe a septic tank should be as large as possible; 78% of people also believed the government is responsible for desludging their tanks, and 63% did not know where their sludge was dumped.
