Securing groundwater resources in South Africa is of critical importance, as it acts as a strategic, often underutilized buffer against climate change and surface water shortages, supporting the livelihoods of millions of people. With two-thirds of the country largely dependent on groundwater and 320 towns relying on it as a primary source, protecting these underground aquifers is crucial for national water security, particularly in rural and semi-arid areas. As surface water resources become more scares (strict enforcement being applied by the Government) and water infrastructure not able to keep up with an ever growing demand, more and more areas will start to become water critical. MVW Geohydrologists aims to alleviate this pressure for the private user as well as larger scale water supply by sustainably using and managing these resources, by specifically working with the client and the environments needs, to deliver a working relationship benefiting both parties.
Key Reasons for Securing Groundwater in South Africa
Drought Resilience and Climate Adaptation: Groundwater is less sensitive to annual rainfall fluctuations than surface water, making it a critical "insurance policy" during severe droughts (e.g., Cape Town, 2015-2018).
Here we secure and manage water resources for a variety of activities.
Essential Source for Rural Communities: Over 90% of rural communities rely on groundwater for daily survival, making its protection crucial for health and poverty eradication.
MVW Geohydrologist have multi-disciplinary skills in this area and have provided groundwater resources ranging for one borehole to in excess of 20 boreholes for larger well-field development.
Agricultural and Industrial Use: Groundwater is vital for irrigation, particularly in the drier, sparsely populated regions, where it drives local economies.
As farming becomes more challenging and restrictive methods employed in terms of the water quantities that can be legally used, MVWG aim to successfully integrate current water uses with groundwater resources for an optimal working agricultural sector.
Environmental Sustainability: Groundwater helps sustain wetlands, rivers, and ecosystems during dry periods.
This is where MVWG ensures, with years of experience and knowledge, that both the client and environment sustainably benefit from groundwater resources.
Major Threats to Groundwater
Pollution: Due to failing, unlined wastewater treatment sites, mining, agricultural chemicals and animal waste products as well as industrial activities, groundwater is increasingly at risk of contamination by harmful bacteria (e.g., E. coli) and heavy metals.
MVW Geohydrologist have extensive experience working with all these sectors and the challenges facing them and have successfully mitigated contamination on projects in the past.
Over-abstraction: If too much water is extracted faster than it can be recharged, it leads to depletion and, in coastal areas, causes irreversible saltwater intrusion.
These issues have been observed and MVWG has helped municipalities as well as private clients to better manage a resource which can supply a reliable quantity of water over many years.
Poor Management and Knowledge Gaps: A lack of consistent monitoring and management, combined with under-capacity at local municipality levels, threatens the long-term sustainability of aquifers.
MVWG aims to fill this gap with years of experience and knowledge to deliver a service which seamlessly integrates human needs with environment requirements.
