Reservoirs Struggle with High Demand: Joburg and Tswhane To Experience Water Outages
As Johannesburg and Tshwane grapple with a water outage, both cities are facing critical challenges in ensuring a consistent water supply for their residents. These shortages are primarily caused by strained reservoir capacities. The reservoirs stretched to their limits due to an increase in water consumption and fluctuating weather conditions. The situation has sparked widespread concern, with officials working to implement measures aimed at regulating water usage and stabilizing the supply.

The Root Cause of Water Outages
Water outages in Johannesburg and Tshwane are not a new issue, but recent developments have escalated the problem. Johannesburg Water implemented stringent water throttling measures across various parts of the city. This is in response to the surging demand and to protect its reservoir systems. The main goal of these measures is to regulate water usage, ensuring that the city’s reservoirs do not run dry.
The impact of these throttling measures has been most noticeable in areas where water usage has reached unsustainable levels. Johannesburg Water, in an official statement, highlighted that throttling efforts will help regulate demand during peak hours. This will give the reservoirs a chance to replenish and maintain their vital role in the city’s water supply system.
Affected Areas in Johannesburg
From Sunday, May 11, 2025, multiple reservoirs across Johannesburg began throttling their water flow for up to 24 hours a day. The President Park Reservoir in Region A, for example, has been throttled from 6:00 am to 6:00 pm to alleviate pressure. In other areas, such as Cosmo City and Diepkloof, a complete 24-hour throttling has been implemented. The throttling was implemented from 8:00 pm on Sunday until 8:00 pm on May 12. There was full closure of the reservoirs during that time.
Johannesburg Water clarified that households might still see some water flow shortly after the reservoirs are closed. Full water supply could take between one to three hours after the throttling periods end.
Infrastructure Maintenance to Address Water Outages
In addition to throttling, Johannesburg Water is using the opportunity to carry out necessary repairs and maintenance on local infrastructure, which could have contributed to the irregularities in the water supply. Officials have emphasized that while the maintenance work may cause temporary inconvenience, it is essential for long-term sustainability.
The water utility further urged residents to use water sparingly and report any visible leaks to reduce unnecessary consumption during these challenging times. By ensuring that all infrastructure is in optimal condition, Johannesburg Water hopes to minimize the risk of future disruptions.
Tshwane’s Water Management Efforts
Meanwhile, in Tshwane, similar water management challenges are unfolding. The City of Tshwane has announced scheduled maintenance on the Montana Reservoir from Monday, May 12 to Wednesday, May 14, in response to reports of discolored water. During this maintenance period, residents in areas served by the Montana Reservoir, including Magalieskruin, Sinoville, and several surrounding extensions, will experience reduced water pressure, especially during peak demand times.
Tshwane is making efforts to ensure that water is still available to residents by using a temporary bypass pipeline to supply water. However, this bypass has a lower capacity than the main reservoir, leading to noticeable pressure reductions. Residents are being urged to conserve water during this period to prevent further strain on the temporary system.
Water-Saving Tips for Residents
With both cities facing significant water challenges, residents are urged to minimize their water usage. The City of Tshwane has provided several tips to help residents save water during this critical period, including:
- Avoid watering gardens: With limited water resources, postponing gardening activities can significantly reduce consumption.
- Do not wash vehicles or pavements: Using a hose to clean vehicles or pavements can waste large amounts of water.
- Postpone filling swimming pools: Filling pools during water shortages exacerbates the strain on the system.
- Flush toilets only when necessary: Reducing toilet flushes helps minimize water usage.
- Close taps while brushing teeth: Small daily habits can collectively make a significant impact.
The Way Forward: A Call for Cooperation
Both Johannesburg and Tshwane officials have called for public cooperation as they work to address water shortages and improve the reliability of the water supply systems. By encouraging responsible usage and maintaining critical infrastructure, the cities hope to stabilize water flow and ensure a more sustainable future for their residents.
While the water outages currently affecting Johannesburg and Tshwane may cause inconvenience, these measures are essential to safeguard the long-term water security of the regions. In the face of rising water demand and environmental challenges, collaboration between local authorities and residents is critical to navigating this crisis effectively.
Water outages in Johannesburg and Tshwane are becoming increasingly severe, with demand outpacing the capacity of city reservoirs. As both cities continue to implement throttling and maintenance measures, the responsibility falls on residents to conserve water and support the efforts made by authorities to ensure a reliable water supply. By working together, both cities can overcome this challenge and secure sustainable water systems for future generations.
