As parts of Johannesburg endure water outages and low pressure, residents want clear answers: who is actually responsible for the taps running dry? In Gauteng’s complex water network, two key players dominate – Rand Water and Johannesburg Water – each with distinct roles. Understanding this division is not just technical; it’s critical for accountability and solutions.

Two Key Players in Gauteng’s Water Supply
Gauteng’s water reaches homes and businesses through a chain that starts with Rand Water, the bulk supplier, and ends with Johannesburg Water, the city distributor.
- Rand Water handles the wholesale side. It draws raw water from rivers and dams, purifies it to drinking standards, and pumps it in bulk to municipalities and industries.
- Johannesburg Water takes over within the city. It buys treated water from Rand Water, stores it in local reservoirs and towers, and distributes it through thousands of kilometers of pipes to households and businesses.
In short: Rand Water purifies and supplies; Joburg Water delivers and maintains. As a joint government release explained, “Johannesburg Water purchases treated water from Rand Water and distributes it to residents. Rand Water procures raw water from the Department of Water and Sanitation, treats it, and pumps it into the municipality’s reservoirs.”
Rand Water: Bulk Supplier to Millions
Founded more than a century ago, Rand Water has grown into one of the world’s largest bulk water utilities and the biggest in Africa. It pumps an estimated 4.5 billion litres daily to 17 municipalities, 27 mines, two railways, 937 industries, and about 18 million people. Johannesburg is its biggest client.
Rand Water’s infrastructure spans thousands of kilometers of pipelines, huge pumping stations, and 60 bulk reservoirs. These facilities move water uphill from the Vaal River System to Gauteng’s high-altitude metros.
The utility operates under a license from the Department of Water and Sanitation (DWS), currently allowing 1.802 billion cubic meters per year. But with Gauteng’s soaring demand, Rand Water has often pumped at full capacity. “We are now pumping at full capacity,” Rand Water spokesperson Makenosi Maroo admitted during the 2025 outages, stressing that the utility works “in close liaison with our customers to achieve sustainable supply.”
Rand Water cannot increase supply overnight; its capacity depends on dam levels, national allocations, and massive infrastructure projects such as the Lesotho Highlands Water Project Phase II, due to add half a billion cubic meters by 2028.
Johannesburg Water: City Distributor and Caretaker
Once Rand Water delivers treated water, Johannesburg Water (JW) takes responsibility. This municipal-owned utility supplies about 1.6 billion litres daily across the metro, while also treating nearly 900 million litres of wastewater. It manages local infrastructure – pipes, pumps, reservoirs, towers, and meters – and responds to leaks, bursts, and pump failures.
JW’s challenge is formidable. Ageing pipes and underinvestment have left the city losing around 35% of its water to leaks and bursts – more than double the international norm of 15%. Every burst pipe not only wastes water but can cut supply to whole neighbourhoods for days.
Johannesburg Water has plans on the table – new reservoirs, pumping stations, and pipe replacements – but progress has been slow. Civil society activist Ferrial Adam of WaterCAN criticised: “The solutions are well-known and urgent. What is missing is leadership and accountability from the City of Johannesburg.”
Why Knowing the Difference Matters
Confusion about “who’s to blame” fuels frustration whenever taps run dry. City officials often accuse Rand Water of under-supplying, while Rand Water points to Johannesburg Water’s failing infrastructure and high demand. The truth is more complex: both sides play a role.
For example, in September 2025, Rand Water’s Eikenhof pumping station tripped due to a power failure, cutting the bulk supply. Even after restoration, Joburg Water’s reservoirs took days to recover. Meanwhile, chronic leaks and illegal connections within the city drained precious reserves.
As the DA in Johannesburg noted in a statement, “The city can no longer blame municipality alone. It must take accountability for its collapsing infrastructure.”
Collaboration and Solutions in the Pipeline
Recognising the crisis, the Minister of Water and Sanitation, Gauteng Premier, Johannesburg mayor, and Rand Water leadership convened urgent talks in late 2024. The outcome was a joint plan:
- Johannesburg Water is committed to fixing leaks, refurbishing infrastructure, and ring-fencing water revenue for reinvestment.
- Rand Water pledged to rehabilitate bulk infrastructure while preparing for new supply sources by 2028.
The City of Johannesburg also introduced a “turnaround strategy” for Johannesburg Water, centralising accountability and reinvesting in reservoirs and pipe replacement.
On the bulk side, Rand Water is expanding treatment plants and building new reservoirs, while warning that Gauteng must learn to live within current water allocations until new projects come online.
The Role of Citizens: Why Every Drop Counts
Gauteng consumes an average of 279 litres per person per day – about 60% higher than the global average for a water-scarce country. This overuse strains both Rand Water and Johannesburg Water.
To address this, the DWS, Rand Water, and Gauteng municipalities launched the Platform for a Water Secure Gauteng, a public campaign encouraging smarter water use. Residents can now access real-time data through the Water Security Dashboard, tracking dam and reservoir levels to understand the system’s pressures.
Rand Water CEO Sipho Mosai insists: “Water is a public good. How the system works should be public knowledge.”
Final Word: Shared Responsibility, Shared Solutions
So, who does what? Rand Water supplies in bulk. Johannesburg Water delivers locally. Both must work seamlessly for taps to run.
For residents, the takeaway is clear: water security depends on both infrastructure investment and responsible consumption. Solutions require cooperation across government, utilities, civil society, and households.
Here’s what you can do in Gauteng:
- Conserve water every day – every litre saved eases pressure on the system.
- Follow water restrictions when they’re in place.
- Report leaks and bursts to Johannesburg Water immediately.
- Stay informed through official updates like the DWS dashboard.
- Hold leaders accountable for infrastructure upgrades and delivery.
With collaboration and accountability, Johannesburg can turn its water troubles around. Water security is everyone’s business — and every drop saved brings the city one step closer to a sustainable future.
