Johannesburg Water Crisis: Aged Infrastructure, Governance Uncertainty, and Daily Struggles for Citizens

Johannesburg, the largest city in South Africa, is facing a severe water crisis, impacting millions of its inhabitants scattered throughout its sprawling urban area. Water shortages are the result of a number of interconnected factors: aging infrastructure, neglected maintenance, externalities like climate change, and bureaucratic governance matters. This article explores the root causes of Johannesburg’s worsening water crisis, examines its impact on residents, and highlights the initiatives underway to address the issue.

The Crisis: A Deteriorating Infrastructure

Johannesburg’s water infrastructure has been long out of date and no longer capable of supporting the demands of its fast-growing population, which is now over 5 million. The city’s water infrastructure is not just inefficient but overloaded, according to Cliffe Dekker-Hofmeyr’s 2025 report. Johannesburg’s failure to invest in infrastructure has left its water delivery system unable to keep pace with urban growth. New homes and industrial developments often arise without the necessary expansion of supporting infrastructure.

Principal problems are:

Over 2,300 burst pipes across the city.
22 leaking reservoirs above tolerable limits.
A staggering 6,724 leaking pipes, 2,396 burst pipes, 442 defective valves, and 259 leaking hydrants.
A surprising 46% of treated water is lost from treatment to consumers.

This failure of infrastructure means that enormous quantities of treated water get lost in transit, adding to the crisis.

Sustained water supply disruptions have become a normal part of life in Johannesburg. A key cause of these disruptions is the city’s dependence on energy-intensive water treatment and pumping plants, which struggle to operate consistently amid South Africa’s ongoing energy crisis.

Rand Water, the city’s supplier of bulk water, has been forced to conduct prolonged shutdowns for priority maintenance works. For instance, in late June 2025, a 21-day upgrade program resulted in huge water cuts in areas like Soweto, Randburg, and Roodepoort. During these periods:

Low water pressure or complete water outages affect entire neighborhoods.
Recovery times last up to two weeks.
Logistical delays typically afflict emergency water tanker deliveries.

Load shedding, which results in electricity outages across the city, also aggravates the situation because pump stations are closed down, further interfering with water supply, particularly to high-altitude settlements served by gravity-fed networks.

The Everyday Life of Residents

Shortages of water are an everyday thing for the majority of Johannesburg residents. Residents have countered by:

Filling buckets during periods of supply to store water in advance.
Installing water storage tanks to absorb spasmodic water supply.
Relying on tanker supplies during supply disruptions.

The impact is felt most acutely in hospitals and schools, where clean water is essential for hygiene and disease prevention. Without reliable access, the risk of waterborne illnesses (such as cholera and typhoid) rises sharply, particularly in vulnerable communities. The crisis is no longer just about inconvenience – it is a full-scale public health emergency. [Greenpeace, 2025]

This crisis is particularly burdensome for slum communities, where clean, consistent water was already in short supply. In these areas, daily contention over clean drinking water is compounded by the lack of resources and infrastructure.

Governance Capacity and Institutional Constraints

Uncertainty of governance has been a primary impediment to ending the water crisis in Johannesburg. The city has had seven different mayors since the past three years, thus being deprived of strong leadership and policy uncertainty. This has hindered urgent infrastructure projects and exacerbated the problem.

Other operational impediments are:

Unless there is sustained and stable leadership, and targeted investment in the city’s water infrastructure, things are unlikely to improve quickly.
As important as public acceptance is the adoption of new technologies to increase the production of useable water from wastewater streams.“The future of water re-use needs to be integrated, with the use of AI and other advanced technologies becoming part of the implementation plan and critical strategy in addressing global water scarcity,” says Nonhlanhla Kalebaila.

The repair fleet of vehicles operating at just 55% capacity.
Johannesburg Water staff shortages, which have limited the city’s ability to deal with water-related issues efficiently.
Almost 50% of non-revenue water losses are due to leaks, illegal connections, and unbilled consumption.

What’s Being Done, and What Residents Can Do

The Gauteng Provincial Government has implemented Level 1 water restrictions and revised tariffs to encourage wiser usage of water. Johannesburg Water has also called upon residents to:

Report burst pipes or leaks immediately in order to prevent wastage of water.
Limit non-essential use of water to save supply.
Store clean drinking water safely wherever there is a supply.
Obtain information on water matters through the Johannesburg Water website and social media platforms.

Progress

The Johannesburg water crisis is a stark reminder of the dangers of underinvestment in key infrastructure. Instability in governance and climate change have doubled the risks for the city, but if action is taken quickly, a solution is achievable.

To address this crisis, the city will require:

Massive investment in fixing and renovating pipes.
Transparency and stable governance to ensure policy consistency and efficient service provision.
Public participation to promote water conservation and efficient utilization.

With climate change increasing, Johannesburg needs more than ever before to future-proof its water infrastructure and build resilience to be able to weather future shocks. Long-term, detailed planning by itself can make the city have a stable and sustainable water supply for all its residents.
