Groundwater Offices

Data Management



Groundwater Dictionary





At National Office the Directorate: National Hydrological Services, in terms of groundwater, is responsible for directing the assessment of groundwater resources, data acquisition and data management for capacity building and the development and maintenance of information systems in this regard. This is done to ensure the sustainable development of groundwater countrywide through the establishment of monitoring infrastructure and network management.

The Groundwater Offices are the main implementers of the National Water Act. In order to fulfil this mandate they execute the following functions: technical advice and support; regional monitoring; groundwater resource assessments and exploration including drilling for collecting sub-surface information; evaluation and recommendations for licensing; data management and information extension.  


Registration of Water Drilling Contractors of South Africa

An estimated 80 000 to 100 000 boreholes are being drilled annually. The data generated through the drilling of this number of boreholes can enhance the knowledge of the occurrences and utilisation of groundwater tremendously and thus it is imperative to get the data onto the Department databases. At the same time, it will enhance the Department's ability to execute its mandate to protect, manage and control the groundwater resources of the country.  

An international search has shown that it is common practice to register drilling contractors thus the Department has successfully created a platform on the National Groundwater Archive (NGA) since the inception of the NGA system and has recently enhanced this platform.

NGA enables the registration and updating of drilling companies and other stakeholder information and hereby encourage all stakeholders to register their drilling and hydrogeological related data to enable the Department in having a database of contractors.

The benefit of registering includes opportunities to receive training as part of the Southern African Development Community – Groundwater Management Institute (SADC GMI) capacity building on borehole drilling activities, continuous information sharing and distribution among others.

In addition, the Department has noticed that currently there are no legal and licensing requirements for borehole drilling companies in South Africa. The Department is at an early stage of planning the development of the framework for regulating drilling activities in South Africa. The Department’s intention is not to license borehole drilling companies but rather regulate borehole drilling activities.

The Review and Update of the Hydrogeological Map Series and Information Brochure of Polokwane, South Africa

The Department of Water and Sanitation in collaboration with South African Development Community – Groundwater Management Institute (SADC-GMI) is currently running a project on the Review and Update of the Hydrogeological Map series and information brochure of Polokwane, South Africa.

The project is financed through a Grant from the Global Environment Facility (GEF) and multi donor trust fund Cooperation in International Waters in Africa (CIWA). The total Grant for the implementation of the project is about R2 million (125 000 USD). Anticipated project implementation period is 20 calendar months, between September 2023 to March 2025.

The main objective of the proposed project is to update the Hydrogeological Map series and information brochure of South Africa within the Limpopo Province and reduce the scale from
1: 500 000 to at least 1: 250 000 or 1: 100 000 or smaller where possible.

The targeted map series is for Polokwane 2326 (Pietersburg). The other objective is to develop methodology on updating existing Hydrogeological Maps of South Africa. The map will be an interactive map digitized and uploaded on the Ministry database and systems.
