The Inkomati-Usuthu Catchment Management Agency appointed GeoAfrika Technologies to manage and carry out the Validation and Verification of Existing Lawful Water Use, in terms of Section 35 of the National Water Act, in the Usuthu Catchment area. This project involved the generation and manipulation of various spatial and non-spatial datasets to build a per property water use activity profile for both current and defined historic periods.

The process covered water use for urban and industrial use, commercial forestry, irrigation and water storage.
