Johannesburg is currently grappling with a severe water crisis. Reservoir levels across the city have dropped to critically low points. This situation is compounded by ageing infrastructure, extensive maintenance work, and high water demand. Consequently, millions of residents are vulnerable to water shortages and intermittent supply.

Critical Infrastructure Challenges
The city’s water system is under immense strain due to decades of underinvestment. Additionally, a growing maintenance backlog is estimated at R27 billion. Johannesburg Water has revealed that nearly half of its reservoirs — 42 in total — are leaking. Unfortunately, only limited funds are available to repair 20 of them. This has resulted in a staggering 46% loss of water through leaks, burst pipes, and failing valves, severely impacting supply reliability.
The vehicle fleet responsible for urgent repairs operates at just 55% capacity, further hampering maintenance efforts. These challenges have led to widespread water outages, affecting approximately 60% of Johannesburg’s population at various points in 2025.
Impact of Rand Water Maintenance
From 30 June to 2 July 2025, Rand Water, the bulk water supplier, conducted major maintenance on critical infrastructure at the Eikenhof and Zwartkopjes systems. This maintenance caused reduced water pressure and temporary outages in several Johannesburg Water systems, including areas such as Soweto, Randburg, Roodepoort, and Lenasia.
The maintenance is part of a broader programme running from June 30 to July 21. It aims at increasing plant capacity, improving reliability, and preparing for higher supply volumes expected from August 2025. Residents were advised to store water in advance. They were provided with alternative water supplies at strategic points during outages.
Water Restrictions and Community Impact
In response to the crisis, Gauteng Province imposed Level 1 water restrictions, urging residents to conserve water. Johannesburg Water also introduced new tariffs to manage demand and fund essential repairs.
Communities across the city have experienced “watershedding,” a term coined to describe scheduled water outages similar to electricity loadshedding. This has forced residents to queue for water and rely on municipal tanker trucks for basic needs such as cooking and hygiene.
The crisis affects all socioeconomic areas, including affluent neighbourhoods, highlighting the widespread nature of the problem.
Government and Expert Responses
City officials, including Johannesburg Mayor Dada Morero, have acknowledged the severity of the crisis. Emergency measures, such as deploying water tankers, are in place, but the scale of the problem exceeds current capacity.
Water experts have called for urgent intervention from provincial and national governments. Carin Bosman, a specialist in water infrastructure, warned that Johannesburg Water requires serious scrutiny and support to avoid further deterioration.
Outlook and Recovery Efforts
Following the completion of Rand Water’s maintenance, full recovery of water systems is expected to take up to 14 days. Meanwhile, Johannesburg Water continues to prioritise repairs on leaking reservoirs and pipes.
The city is also tackling illegal water connections and leakages to improve overall system efficiency. However, with a vast network of over 12,000 kilometres of pipelines and thousands of leaks and bursts recorded annually, the recovery will be gradual.

Water Crisis
Johannesburg’s ongoing water crisis is a complex challenge driven by ageing infrastructure, maintenance backlogs, and rising demand. While planned maintenance and emergency responses offer some relief, sustainable solutions require significant investment and coordinated government action. Residents are urged to continue conserving water and stay informed through official Johannesburg Water updates.
