South Africa’s R400 billion water crisis: fixing leaking pipes before it’s too late
By Adrian Ephraim
WHEN President Cyril Ramaphosa stood at Cape Town City Hall in February to deliver his 2026 State of the Nation Address, he did not mince words. Water, he told the nation, was now “the single most important issue” for millions of South Africans. The money followed: R156 billion committed to water and sanitation infrastructure over three years, part of a historic R1 trillion public infrastructure allocation.
But engineers are making a pointed argument – the money, however large, will achieve little if the fundamental failure at the heart of the crisis is not addressed first.
The leak before the dam
South Africa’s No Drop report found that close to half (47%) of municipal water is lost as “non-revenue water” – because of leaking pipes, unreliable or non-existent water meters, illegal connections and poor billing and revenue collection. Auditor-General findings put the cost of those losses at R14.89 billion in a single year. Government estimates suggest more than R400 billion is required to rehabilitate municipal water and sanitation infrastructure nationwide.
The maintenance picture is equally damning. While 8% of the budget should go to infrastructure maintenance, the actual figure is often just 2%, leading to expensive breakdowns. By the end of the second quarter of 2025/26, the country’s eight metros had collectively spent only 31.5% of their R5.8 billion water infrastructure budget, against a benchmark that should have been above 50%. Nelson Mandela Bay reported spending just 3.4% of its capital budget for water in that period.
It is a crisis of managed neglect; a system not failing suddenly, but decaying for decades under the weight of deferred decisions.
“Failure rates reach disastrous levels”
Professor Kobus du Plessis, Professor of Hydrology and Environmental Engineering at Stellenbosch University, has been direct about what is at stake when infrastructure is left without care. Commenting on Stellenbosch’s Level 2 water restrictions in February, he emphasised that “if not maintained appropriately, failure rates [of water distribution] significantly increase and reach disastrous levels which are extremely difficult to stop and turn around, replacing at a significant cost frequently being the only option.”
He also contextualised the population pressure dimension: “If no extra resources are added, then the risk of failure increases significantly.”
The observation is not specific to Stellenbosch; it describes the national condition. Ramaphosa acknowledged this in SONA: the real challenge facing South Africa is not a lack of water, but the struggle to get water from dams to people’s taps.
The engineering toolkit
The engineering sector is not waiting for policy to catch up. Specialists in flow measurement, pipe rehabilitation, pressure management, decentralised water systems and storage point to technologies already delivering measurable results, and argue that the government’s R156 billion commitment must flow into these solutions, not simply into new bulk infrastructure.
Smart metering and flow measurement allow municipalities to see in real time where water is entering and leaving distribution networks, detecting leaks, identifying illegal connections, and generating accurate billing data.
Pipe lining and rehabilitation technologies such as cured-in-place pipe (CIPP) lining can extend the lifespan of deteriorated mains without excavation, providing a faster and more affordable fix than full replacement.
Pressure management, controlling pressure within distribution networks, remains one of the most cost-effective non-revenue water interventions available, with municipalities that have implemented district metered areas recording significant reductions in both burst frequency and volumetric loss.
Funding the fix
A performance-based conditional grant introduced in 2025, allocated R27.7 billion over the medium term, requires metropolitan service entities to reinvest revenues from services into infrastructure. A further R54 billion in incentives has been directed at metros to reform water and sanitation services, with the explicit goal of ringfencing water revenue for reinvestment. PPP regulations have also been revised, with municipal amendments expected by June 2026.
Melanie Humphries of Investec Sustainable Solutions put it plainly: “Water is the crisis that has been building quietly in the background. Too often, it only becomes urgent once systems are already under strain.”
The R400 billion problem is not solved by R156 billion in commitments alone. But targeted investment in technologies that reduce losses, rehabilitate pipes and build measurement intelligence into municipal networks could stabilise a system currently losing nearly half of what it produces. The engineering solutions exist. What is needed now is the institutional will, the ring-fenced funding and the technical capacity to deploy them at scale – before the window for intervention closes.
