South Africa’s worsening water infrastructure crisis now requires an estimated R400 billion to repair and modernise, despite major gains in access to water services since the end of apartheid.
While official figures show that access to basic water services has improved from 55% in1994 to around90% in2026, millions of households continue to experience unreliable supply, frequent outages and concerns over water quality.
The Department of Water and Sanitation has acknowledged that the crisis is no longer simply about access, but about the failure of ageing infrastructure and weak municipal service delivery.
Infrastructure access improved, but reliability worsened
Government officials say the country’s water challenge reflects two contrasting realities.
On paper, national coverage has expanded significantly over the past three decades.
In practice, however, many households connected to municipal networks still face dry taps, low pressure, contamination risks and repeated supply interruptions.
According to the department, more than 100 water services authorities have been identified as poor-performing through the Blue Drop and Green Drop monitoring systems.
Over the past five years, roughly R30 billion has already been directed to the worst-affected municipalities in an effort to restore infrastructure reliability.
Yet this remains far below what is required.
The current infrastructure backlog is estimated at R400 billion nationally, while available funding through grants remains only a fraction of that amount.
Private sector and accountability measures introduced
With public finances under pressure, government has increasingly turned to blended finance and private-sector partnerships.
The Department of Water and Sanitation, together with the Development Bank of Southern Africa and South African Local Government Association, has established a Water Partnerships Office to help municipalities prepare investment-ready infrastructure projects.
The goal is to attract private capital into water and sanitation upgrades, particularly in provinces such as Limpopo and the Northern Cape where pilot projects are already underway.
National Treasury has also introduced a new R54 billion performance-based grant incentive for metropolitan municipalities.
Access to these funds will depend on measurable progress in reducing water losses, improving governance and ring-fencing water revenues for infrastructure maintenance.
Government data continues to show that non-revenue water — largely lost through leaks, illegal connections and poor billing systems — remains one of the biggest contributors to the crisis.
At the same time, Parliament is considering amendments to water services legislation aimed at addressing long-standing governance failures at municipal level.
For rural and unserved communities, additional interventions include boreholes, protected springs and household rainwater harvesting systems.
Officials say these programmes form part of a broader five-year national plan to restore reliable water and sanitation services across South Africa.
