JOHANNESBURG, Gauteng — As Johannesburg water outages continue to disrupt thousands of residents, Gugulethu Guma, Operations Manager at Johannesburg Water, has outlined a comprehensive multi-billion rand infrastructure overhaul to address the city’s aging pipelines and systemic pressure failures. The widespread disruptions have sparked urgent questions regarding the state of the metro’s water infrastructure, prompting the utility to accelerate both short-term repairs and long-term capital investments.
According to Guma, recent pipe bursts in several heavily affected suburbs are actively being resolved. In Alexandra, a major burst was repaired, allowing for the gradual restoration of supply, prioritizing lower-lying areas first. Similarly, Weltevreden Park has seen supply resumes following the successful repair of localized burst pipes.
The situation in South Hills, which experienced prolonged disruptions, was largely tied to challenges faced by the metro’s bulk water supplier. Once the bulk supplier repaired its own infrastructure constraints, the flow into the Johannesburg Water system improved. Guma confirmed that capacity has stabilized, and gradual water restoration is actively reaching South Hills and surrounding southern suburbs.
A Multi-Billion Rand Turnaround Strategy
The ongoing crisis has triggered a massive financial intervention involving the National Minister of Water and Sanitation and the City of Johannesburg. Following severe supply disruptions over the past two years, a 10-year turnaround strategy was launched in the 2024 financial year.
Guma revealed that approximately R1.5 billion was injected into capital projects last year alone to stabilize the network. Looking ahead, the utility plans to invest upwards of R10 billion over the next five years to transform the network into a more resilient and sustainable system. Addressing historical underinvestment, Guma noted that the utility ideally requires close to R3 billion per financial year to effectively manage current infrastructure demands and clear the massive maintenance backlog accumulated over many years of delayed investment.
Tactical Interventions: Controlling the Pressure
To mitigate the immediate crisis, Johannesburg Water is deploying short-term tactical interventions. These include targeted spot repairs, localized pipe replacements, and the critical installation of Pressure Reducing Valves (PRVs). Guma explained that uncontrolled pressure is a primary driver of multiple simultaneous pipe bursts, making PRVs essential for stabilizing the network.
Long-term strategies focus heavily on expanding storage capacity through the construction of additional reservoirs to meet the city’s growing demand and prevent future system collapses.
Upgrading the City’s Most Vulnerable Zones
When identifying the most vulnerable segments of the water value chain, Guma pointed to the older, central suburbs stretching from the Johannesburg CBD toward Brixton and Auckland Park. Because these areas rely on heavily constrained and aged infrastructure, they are currently receiving concentrated investment.
To provide immediate relief to these central zones, new infrastructure—including a newly commissioned Brixton reservoir and tower—has been brought online to cushion local residents, businesses, and hospitals.
Furthermore, the utility has identified 43 reservoirs across the network that require urgent attention. Of these, 23 have been prioritized for short-to-medium-term rehabilitation to maximize water retention and storage times, ensuring a more reliable supply for the city’s future.
