Rand Water Maintenance: Eikenhof Pump Station
Maintenance at the Eikenhof Pump Station continues according to the planned schedule until 12 July 2024. Currently, pumping has been increased to approximately 92% to assist with recovery. While the majority of Johannesburg Water systems are steadily restoring, high levels of consumption that exceed the available supply still present problems for some systems.
Commando system
There is not enough supply to meet the demand, which is putting strain on the system. Reconfigurations are in progress for equitable distribution of available capacity.
Crosby Reservoir
The reservoir was critically low this morning but expected to improve during the day and overnight. Pumping to the Brixton Reservoir continues between 50% and 70%, depending on available inflows.
Brixton Reservoir and Tower
The reservoir is low but supplying fairly due to poor supply and high demand. The outlet will be closed overnight to build capacity. While the Brixton Tower is supplying normally, it will be affected by reservoir levels.
Hursthill 1 and 2 Reservoirs
The Hursthill 1 and 2 Reservoirs experienced improvement overnight but remain low. Currently, both reservoirs are supplying fairly but experiencing high demand. Poor pressure is expected in high-lying areas, to some extent no water maybe experienced.
As part of interventions, the Hursthill 1 Reservoir has been reconfigured to boost supply, while the outlet of Hursthill 2 Reservoir improved overnight. Hursthill 2 has also been reconfigured to augment supply and is supplying fairly.
Randburg systems
All systems have improved and supplying fairly. Intermittent supply is still expected as the maintenance programme continues. Pumping to the Waterval and Quellerina towers commenced this morning, and both are supplying fairly. However, intermittent supply is still expected as the supplying reservoir is still low.
Johannesburg Water will closely monitor all systems and continue to provide alternative water supply to systems affected customers.

Rand Water Maintenance: Hursthill 1 and 2 supply zones
Maintenance at Eikenhof is set to continue according to the planned schedule until 12 July 2024. During this time, some areas will continue to have water supply, but at a reduced level.
While water supply has improved in most systems, Johannesburg Water is aware that there are areas within the Hursthill 1 and 2 Reservoir supply zones that are experiencing intermittent supply, while some are without water.
This is due to airlocks in the system, which the entity’s team are currently on the ground flushing out the network to improve supply pressure and to protect the infrastructure against multiple pipe bursts that can result from airlocks.
Air prevents water flow and can lead to reduced supply pressure (poor pressure to no water for residents). If not removed or flushed out of the system, air can also cause water hammer in a system, which in turn can cause instantaneous pressure surges and this causes bursts, especially in older infrastructure pipes and connection points.
The following are some of the areas within the Hursthill 1 and 2 supply zones that are affected (this includes surrounding areas):
•Claremont
•Newclare
•Westdene
•Newlands
•Coronationville
•Westbury
•Sophia Town

Systems Update
Palmiet Pump Station Maintenance
The first phase (part 1 of 3) of the Palmiet Pump Station maintenance is in progress. Pumping was decreased to 60% capacity for eight hours (until around 16:00). This will then be followed by a gradual increase to 100% capacity.
Johannesburg Water systems supplied from Palmiet will experience disruptions, impacting all direct feeds.
South Hills Tower
The tower is supplying normally but is declining due to poor incoming supply.
Alexander Park Reservoir
The reservoir was closed overnight to build capacity. The water levels are currently sitting at 62% and is currently declining due to reduced incoming supply.
Randjieslaagte Reservoir
The reservoir is currently at 62% capacity and is currently declining due to reduced incoming supply.
Linksfield Reservoir
The reservoir is at 68% capacity and is currently declining due to reduced incoming supply.
Midrand systems
Overall, the Midrand systems dropped slightly in water levels, but continue to supply normally. The following systems are affected:
- Diepsloot and Steyn City Reservoirs
- Erand Reservoir and Tower
- Grand Central Reservoir and Tower
- President Park Reservoir and Tower
- Rabie Ridge Reservoir and Tower
- Development Bank Reservoir and Tower
- andjesfontein ReservoirAll direct feeds (Sandton systems)
Overall, the Sandton system is supplying normally, although water levels dropped slightly. As and when it is required, supply in some systems is closed to build capacity, or water is diverted from one reservoir to another to balance the system.
The following systems are affected:
- Linbro Park 1 and 2 Reservoirs:
- Marlboro Reservoir
- Morningside Reservoir
- Bryanston Reservoir and Tower
- Illovo Reservoir and Tower
- Direct feeds (Linbro and Marlboro direct feeds)
The systems will demonstrate varying responses to the decreased pumping, with some showing poor pressure, while others may have a combination of poor pressure to no water.
Johannesburg Water continues to monitor all systems and provide alternative water supply to systems affected by prolonged outages.

Rand Water Maintenance Update
The Zwartkopjes Pump Station is currently running at 100% maximum capacity. However, due to the interconnected nature of the systems, they mutually augment and affect each other. There is a gradual improvement in the performance of the systems that are being supplied by the Zwartkopjes Pump Station.
Crown Gardens Reservoir and Tower
- Crown Gardens Reservoir made gains overnight and is now at 79% capacity. The outlet has been opened at 50% to gradually charge the system and supply the area. Residents residing in low-lying areas within the reservoir zone are receiving water; while those in higher-lying areas will experience a combination of poor pressure to no water while the system Johannesburg Water will be monitoring the charging of lines and any potential airlocks and bursts.
- Crown Gardens Tower: pumping continues, and the tower is supplying It is currently sitting at 45% and continues to gradually improve. Residents in the tower zone are receiving normal water supply as the system undergoes recovery.
- Eagles Nest Reservoir is currently at 29% capacity and maintained some stability overnight. It is supplying fairly, including the Alan Manor and Naturena
reservoirs.
- Parktown and Berea reservoirs
− Parktown 2 Reservoir is currently at 41% capacity, with a slight improvement overnight and is supplying normally.
− Berea Reservoir improved overnight and is currently sitting at 41% capacity. It is supplying fairly.
Daleside Pump Station
The pump station is currently running at maximum capacity of 100%, Johannesburg Water’s systems are in the process of recovering.
Orange Farm Reservoir is currently at 28% capacity, showing improvement overnight. However, it remains low due to ongoing high demand on the system. Poor pressure may be experienced, especially in high-lying areas.
Ennerdale Reservoir improved overnight but remains low due to ongoing high demand on the system. Despite efforts to restore the reservoir, high demand for water is affecting the recovery process. Poor pressure may be experienced, especially in high-lying areas.
The Lawley Reservoir is currently at 16% capacity, showing improvement overnight. However, it remains low due to ongoing high demand on the system. Poor pressure may be experienced in the supply zone, particularly in high-lying areas.
Johannesburg Water is monitoring improvements of all systems and will provide updates.
