Long heralded as a crucial technological input for the successes of the Green Revolution in South Asia, for over half a century tubewell technologies have played a decisive, yet unacknowledged role in sustaining cities and towns as well as farms and factories across India. Drawing on a decade of fieldwork and archival research, this chapter recounts the biography of this fantastic technology and its importance to farmers and urbanites as well as its shifting position within larger geopolitical debates and technology transfers. As cities and towns continue to compete with industry and agriculture for groundwater, distribution and access to tubewells will become central to landscape and urban development within the region.
