Key Takeaways
- Gauteng residents face years of stricter water rationing due to unsustainable water consumption patterns.
- The province’s metropolitan municipalities are exceeding their water allocation limits, with Johannesburg, Tshwane, and Ekurhuleni being the main culprits.
- The Department of Water and Sanitation has warned that relief will not come until multiple critical conditions are met, including reducing non-revenue water, expanding municipal storage capacity, implementing water rationing, and increasing supply from the Lesotho Highlands Project.
- Residents are urged to slash their water use, with the average consumption per person per day needing to be reduced from 279 liters to around 164 liters.
Introduction to the Water Crisis
The Department of Water and Sanitation has issued a warning to Gauteng residents, stating that they face years of stricter water rationing despite recent good rains. The warning comes as the province’s metropolitan municipalities, including Johannesburg, Tshwane, and Ekurhuleni, continue to exceed their water allocation limits. According to Rand Water consumption data, the combined weekly consumption for the three metropolitan municipalities reached 3,664 megaliters (ML) per day on January 12, 2026, far exceeding both the permanent agreement of 3,045 ML per day and the temporary target of 3,431 ML per day.
Water Consumption Patterns
The data reveals alarming overuse across Gauteng’s metropolitan municipalities. The green line in the graph indicates the sustainable supply target that municipalities should be working towards, while the blue line represents actual consumption and the red line shows the agreed consumption limit. Recent figures show that Johannesburg Water led the overuse, consuming 1,763 ML per day on January 12, 2026, surpassing its permanent allocation of 1,356 ML per day by a significant margin and exceeding even the temporary target of 1,528 ML per day by 15.4%. Tshwane municipality consumed 864 ML per day against a permanent target of 667 ML, while Ekurhuleni municipality used 1,037 ML per day, just above its permanent limit of 1,022 ML per day.
Warning from the Department of Water and Sanitation
After these figures were released, Sean Phillips, director-general of the department of water and sanitation, issued a warning about the province’s unsustainable water consumption patterns. He stated that Gauteng needs to bring its per capita consumption down significantly, from an average of 279 liters of water per day per person to around 164 liters per person per day, which is the average consumption in the Western Cape. Phillips attributed the core issue to a combination of overconsumption, lack of municipal storage facilities, water lost through leaking pipes, and uncollected revenue.
Conditions for Relief
Phillips outlined the conditions that must be met before Gauteng residents will see an improved water supply. These include reducing non-revenue water, expanding municipal storage capacity, implementing water rationing, and increasing supply from the Lesotho Highlands Project II, which is expected to become operational in 2028 or 2029. He stressed that all of these conditions need to be met together, and that one or two of them is not enough. Phillips also clarified that only municipalities have the authority to implement water restrictions, placing responsibility for enforcement squarely at the local government level.
No Quick Relief in Sight
The warning comes as the Vaal Dam experienced a slight decline from 101.26% capacity to 100.88% capacity. The Reservoir, a water resource information centre, recommended closing the last gate at the Vaal Dam and operating on valve discharge only. With no quick relief in sight, residents are urged to slash their water use and work towards reducing their consumption to sustainable levels. The Department of Water and Sanitation has emphasized the need for a collective effort to address the water crisis, and for residents to take responsibility for their water usage.
Conclusion and Recommendations
In conclusion, the water crisis in Gauteng is a complex issue that requires a multifaceted approach to resolve. The Department of Water and Sanitation has warned that relief will not come until multiple critical conditions are met, including reducing non-revenue water, expanding municipal storage capacity, implementing water rationing, and increasing supply from the Lesotho Highlands Project. Residents are urged to take responsibility for their water usage and work towards reducing their consumption to sustainable levels. By working together, it is possible to address the water crisis and ensure a sustainable water supply for future generations.
