The report by Carewater INREM Foundation draws inferences from studies across the Indo-Gangetic Basin on using local well driller knowledge to construct digital groundwater databases. The low density of current groundwater instrumentation networks in the region is both cost and management intensive, contrary to local knowledge, which has greater spatial coverage and can be obtained at a relatively lower cost. An efficient way to tap such local groundwater knowledge is through well drillers. 

In the absence of groundwater instrumentation networks in India, the knowledge of local well drillers about the location, quality, etc of groundwater aquifers is invaluable.
