South Africa stands at a critical crossroads in its water journey. Ranked the 33rd driest country in the world, it receives just half the global average rainfall. Amidst this, Gauteng, South Africa’s economic hub, relies on strategic water source areas for 67% of its supply.
These areas now face threats from invasive species, poor land management, and pollution, according to the World Wildlife Fund (WWF). This crisis worsens with mounting pressures from climate variability and rapid urbanisation. Systemic inefficiencies also exacerbate the problem: nearly half (47%) of the country’s clean, treated water is lost through leaks, bursts, faulty meters or illegal connections. Addressing these challenges requires a renewed focus on building water resilience across the entire sector.
Securing future water resources is no small feat. The Department of Water and Sanitation estimates that over R90 billion per year will be needed for the next decade to repair and upgrade the country’s water infrastructure. Short-term fixes alone will not suffice. We must build long-term resilience, reimagining how water is valued, governed and managed across every sector of society.
From reactivity to future preparedness
South Africa’s water sector has long operated in reactive mode, responding to droughts, floods and pollution events as they arise. However, this approach is no longer viable. Increasingly erratic rainfall and intensifying extreme weather require a shift toward proactive, climate-resilient planning.
The main challenge in water resource planning lies in adapting to climate variability and changing rainfall patterns. Predictable wet and dry seasons once allowed straightforward storage strategies. Today, intense rainfall occurs over shorter periods, making it difficult to capture and store water efficiently.
Much water is lost to runoff or discharged into the sea. This pattern disrupts short-, medium- and long-term water management. Climate variability and extended drought cycles make it harder to predict and secure reliable water supplies for users. To navigate this complexity, integrated catchment management and proactive risk assessment must take centre stage in water governance.
Future readiness requires moving beyond reactive crisis response. Policymakers must adopt a risk-based, anticipatory mindset. This approach identifies emerging threats, unlocks opportunities and evolves policies and regulations with a sharper focus on implementation and enforcement. Such steps are essential for building water resilience in South Africa’s systems.
Decoupling to unlock collective accountability
South Africa’s water governance follows the progressive and comprehensive National Water Act (1998). Yet the challenge lies not in policy design but in implementation, compliance and enforcement. Encouragingly, renewed focus is emerging. Notably, the National Water Resource Infrastructure Agency now manages bulk water infrastructure, including dams and pipelines.
Water management is divided across three core functions: infrastructure, water services and regulation. To make meaningful progress, greater integration and interoperability between these branches is essential.
Additionally, decentralisation and collaboration across the public sector, private sector, civil society and communities are critical. Water must be embedded in all levels of planning, from mining and agriculture to the consistent delivery of safe, drinkable water. This collective approach strengthens shared responsibility while building water resilience in communities and ecosystems.
Changing culture and perception
A cultural shift in how water is perceived is essential. Stewardship and collective ownership must replace commodification. Water is not just a resource; it is an intrinsic and living part of our ecosystem.
Water quality deterioration is a growing concern. Quantity alone is insufficient; water must sustain life. Wastewater treatment capacity and technical competency at the municipal level, combined with rapid urbanisation, threaten supply reliability. Industrial and mining pollutants further degrade water quality, raising treatment costs and harming ecosystems. Land use changes and habitat loss also erode biodiversity and river system integrity.
Another critical barrier is the undervaluation of water. In South Africa, water is generally underpriced, especially in agriculture, which consumes 60 – 65% of available resources. The gap between price and true cost, including transfer, treatment and environmental impact, undermines incentives for conservation and infrastructure investment.
Addressing this imbalance requires growing public awareness. Transparent communication about water’s finite nature and true value builds trust, supports behavioural change and lays the foundation for building resilience across the country’s water infrastructure.
Shared responsibility is imperative
Despite complexity and challenges, there is cause for hope. South Africa has a robust regulatory foundation and a committed community of professionals working to safeguard our future water resources. While implementation hurdles remain, recent updates to the Water Act and growing engagement from corporates and civil society indicate a positive shift.
Sustaining this progress requires investment in technical capacity and cultivation of a culture of stewardship. Policies must prioritise sustainability not only in design but also in practice.
A guiding principle to embrace is simple: we all live downstream. Water connects us across sectors, communities and ecosystems. Its sustainability is non-negotiable. A collective focus on building resilience ensures water security for future generations.
