Urban water supply and wastewater on a shallow aquifer

Year: 2005
From collection: Vital Water Graphics
Author: Delphine Digout, UNEP/GRID-Arendal
This graphic shows the changes in water supply and wastewater disposal that occur through four stages of growth of a settlement: early settlement; the town becomes a city; the city expands and the city expands further. The changes include increased groundwater pollution and changes in pluvial drainage, the water table and wellfields.
