Systems Update
The demand across Johannesburg Water systems is currently significantly higher, and this is impacting the overall bulk supply.
South Hills tower
Over the past three days, the tower has gradually improved and continues to supply normally.
List of affected areas: /south-hills-tower/
Midrand Systems
Most Midrand systems are currently stable. Although the Rabie Ridge reservoir improved slightly overnight, it is experiencing high demand and low water levels. The reservoir is currently supplying at 30% while the tower remains on bypass mode. Poor pressure to no water can be expected in parts of the supply zone, including Klipfonteinview. Johannesburg Water is monitoring the system for improvements.

Alexander Park reservoir
The reservoir improved overnight and is supplying normally. However, there is high demand on the system. The outlet will be closed overnight to build capacity for the next day.
List of affected areas: /alexander-park/
Eagles Nest reservoir
The reservoir continues to be critically low due to increasing demand and poor supply pressure. Low pressure is expected in the supply zone, especially high-lying areas; however, the system has been reconfigured to boost supply.
List of affected areas: /eagle-nest-reservoir/
Linden 1 reservoir and tower
The reservoir continues to be stable and is supplying normally, while the tower is critically low and is expected to improve overnight. Customers in the tower supply zone may experience poor pressure in high-lying areas.
List of affected areas: /linden-tower/
Soweto Systems
The Soweto systems remained stable overnight and throughout the day, however, they will be affected by overnight throttling (reducing pressure and flow). The bulk supply remains restricted as a Water Demand management strategy. The Zondi reservoir supply is currently at 60%, while the Power Park reservoir supply is at 50%. Areas fed by the Zondi, Doornkop and Power Park reservoirs are affected by low pressure, while high-lying areas are affected by no water. Bramfischerville is supplying at 50%, and poor pressure to no water is expected most parts of the area. Customers in phases 7 and 9 will experience poor pressure to no water. Certain areas supplied by Protea Glen tower and direct feeds are experiencing poor pressure to no water.
List of affected areas:
Zondi reservoir: /zondi-reservoir/
Doornkop reservoir: /doornkop-reservoir/
Power Park reservoir: /power-park-reservoir/
Commando System
• Brixton reservoir: The reservoir is stable and is currently supplying normally.
• Brixton tower: The tower is stable and is currently supplying normally.
• Hursthill 1 and 2 reservoirs: Both reservoirs improved overnight, however, the levels are low and poor pressure to no water is expected in the supply zones. The outlets to both reservoirs are fully opened. Hursthill 1 reservoir has been configured to boost supply while Hursthill reservoir will be closed overnight to build capacity for tomorrow.
• Crosby reservoir: The reservoir is stable and is currently supplying normally.
List of affected areas:
Brixton reservoir: /brixton-reservoir/
Brixton tower: /brixton-tower/
Hursthill 1 and 2 reservoirs: /hursthill-1-and-2/
Crosby reservoir: /crosby-reservoir/
The following reservoirs will either be closed or throttled to 90% overnight to retain water and build capacity.
• Sandton: Illovo, Bryanston, and Morningside
• Soweto: Freedom Park, Doornkop West, Power Park, Orlando East, and Zondi
• Commando: Brixton, Hursthill 2
• Crown Gardens
• Alexandra Park (closed)
• Midrand: Rabie Ridge, Grand Central, President Park, Erand, and Diepsloot
The Randjieslaagte and Berea reservoirs may be throttled overnight if necessary due to high demand.
Customers supplied by these reservoirs may experience poor pressure to no flow. Alternative water supply has been arranged through water tankers for the affected areas. Johannesburg Water continues to monitor the above systems.
Residents are requested to observe level-1 water restrictions which are implemented from 1 September to 31 March. These restrictions prohibit the use of hosepipes to water gardens, wash cars, clean driveways, as well as fill up swimming pools and water features between 06:00 and 18:00. Instead, the use of greywater is encouraged.
