How engineers in the 1960s had ignored local monsoon patterns, designing tanks based on Western textbooks. The result? Every July, untreated sewage flooded a village well. A cholera outbreak. A child’s death. The revised manual, Punmia wrote, was born from that tragedy. The 2-hour rule wasn’t an equation—it was a promise.
