Urbanisation is the predominant global phenomenon of our time, and groundwater from springs and wells has been a vital source of urban water-supply since the first settlements. In the modern era, groundwater capture using deep waterwells with submersible electric pumps has enabled major growth for urban use worldwide. Factors influencing groundwater use are resource reliability for municipal supply, resource accessibility for private supply, reducing river-intake security with pollution, and relatively low waterwell construction costs. The large natural storage of most aquifer systems has made them a vital resource for assuring water-supply security during past droughts and will be particularly critical in future climate-change adaptation.
