Rand Water will affect Johannesburg residents with a water outage starting on 30 June 2025 as it begins a critical 21-day maintenance program. This large-scale infrastructure upgrade will improve the city’s long-term water supply reliability but will cause significant short-term interruptions that impact millions across multiple regions. The Joburg water outage will disrupt several key areas, so residents must prepare for reduced water availability during this period.

Scope and Impact of the 21-Day Water Disruptions
The maintenance will affect several major water systems, including the Commando System (Hursthill, Brixton, Crosby), Lenasia Systems, Randburg, Roodepoort, Soweto, Crown Gardens Reservoir, Eagles Nest Reservoir, and Aeroton Reservoir. During the initial six hours of the outage, no water pumping will occur. This will be followed by 50% pumping capacity for 42 hours, and then 80% capacity for the remaining 19 days. Residents in these areas can expect either complete water outages or significantly reduced pressure throughout the period.
Recent Emergency Repairs and Their Aftermath
This planned maintenance follows emergency repairs completed on 21 May 2025 to the F12/F39 bulk pipeline, which had severely depleted Johannesburg Water’s reserves. Although the emergency work restored critical infrastructure, the system still requires time to rebuild capacity. The upcoming maintenance is essential to ensure the continued reliability and efficiency of the water supply network.
Additional Scheduled Maintenance and Its Effects
Besides the 21-day outage, Rand Water has scheduled other maintenance activities that will impact water supply in various parts of Johannesburg. For example, meter replacements and pressure valve installations are planned in areas such as Cosmo City, Forest Hill, Newlands, Albertville, and Whiteridge North. These maintenance windows typically last between 10 and 14 hours and may cause temporary outages or low water pressure.
How Residents Can Prepare for Water Disruptions
Johannesburg Water strongly urges residents and businesses to store sufficient water ahead of the maintenance period. Using water sparingly during the disruptions will help stabilize the system and speed up recovery. Additionally, residents should report leaks promptly to minimize water loss. Being prepared will reduce inconvenience and help the city manage this critical infrastructure upgrade smoothly.
Joburg Water Outage: Strategic Timing to Minimize Impact
Rand Water chose the cooler months of May to July 2025 for this maintenance to avoid peak water demand periods, which usually begin in August. This timing aims to reduce the overall impact on residents and businesses while ensuring vital infrastructure improvements proceed efficiently.
Essential Upgrades for a Reliable Water Future
Although the 21-day water disruptions will pose challenges for Johannesburg residents, these maintenance activities are crucial for securing the city’s water supply in the long term. By upgrading meters, valves, and pipelines, Rand Water and Johannesburg Water aim to enhance system flexibility, reliability, and capacity. Residents are encouraged to prepare accordingly and support efforts to conserve water during this period.
