The Groundwater Hydrology Committee (GWHC) of ORASECOM undertook a basin wide groundwater survey from the 9th to the 16th of September 2018.

The objective of the Survey was to contribute towards the improved understanding of the groundwater systems in the Orange-Senqu River Basin, by the GWHC Members, through among others, field observations and peer-to-peer discussions on the issues, parameters, characteristics and features in these systems.
For background information on the Survey, as well as on selected visited transboundary groundwater systems in the basin, and pictures click here.
