The Southern African Development Community (SADC) hydrogeological map and atlas provides an overview of the groundwater resources of the SADC region by means of an interactive web-based regional map. The map and atlas is a general hydrogeological map providing information on the extent and geometry of regional aquifer systems. The map is intended to serve as a base map for hydrogeologists and water resource planners, whilst at the same time presenting information to non-specialists.

The compilation of the SADC hydrogeological map took place during the period 1 June 2009 to 31 March 2010. The consultancy was awarded to a consortium consisting of Sweco International (Sweden), Council for Geoscience (South Africa), Water Geosciences Consulting (South Africa) and Water Resources Consultants (Botswana). Sweco was the lead consultant. The project implementation agent (PIA) was the Department of Geological Survey (DGS), Botswana. The overall objective of the project was to improve the understanding of groundwater occurrence within the SADC region and to promote cooperation and better understanding of water resource planning and management.

 The project had to produce the following two main priority results:

• Comprehensive, interactive web-based hydrogeological map of the SADC region;
• Enhanced institutional capacity for producing and using hydrogeological maps in water resources planning, development and management
