Johannesburg Water systems: evening update
Most of Johannesburg Water’s reservoirs and towers were affected by the power failure at Zuikerbosch Water Treatment Plant. As a result, most of the systems lost storage capacity and are currently critically low to empty. Johannesburg Water is monitoring the situation.
The below systems are affected:
South Hills tower
Tower is critically low due to high demand. Low pressure to no water expected in parts of the supply zone. Tower expected to recover overnight. Johannesburg Water is monitoring the situation.
Commando System
- Brixton reservoir: Critically low due to high demand and low supply. Low pressure to no water expected in the supply zone. Outlet will be throttled (flow and pressure reduced) to 70% overnight to build capacity.
- Brixton tower: pumping as normal but remains critical due to high demand and low reservoir level. Poor pressure to no water is expected in high-lying areas.
- Hursthill 1 reservoir: Despite attempts to augment the supply, the reservoir remains critically low to empty. The supply zone will have low pressure to no water.
- Hursthill 2 reservoir: Critically low due to poor supply. Low pressure to no water is expected in high-lying areas. Outlet will be closed overnight to build capacity.
- Crosby reservoir: Critically low due to erratic supply and high demand. Poor pressure to no water is expected in parts of the supply zone.
Crown Gardens reservoir and towers
The reservoir levels are critically low, and the outlet is opened at 50%. Poor pressure to no water should be expected in high-lying areas of the reservoir zone. Both towers are pumping, however, levels may decrease as demand increases during peak hours. Poor pressure to no water is experienced in the supply zone.
Eagles Nest reservoir
Remains critically low due to poor supply. Customers in this supply zone should expect low pressure to no water.
Naturena reservoir
Reservoir levels decreased during the day due to high demands during peak hours. Low pressure to no water is experienced in the supply zone.
Alexander Park reservoir
Critically low due to poor supply and high demand. Poor pressure to no water is expected in high-lying areas.
Berea reservoir
Critically low and on bypass mode. Low pressure to no water expected in the supply zone.
Linden 1 reservoir and tower
Critically low due to high demand and poor supply. Low pressure to no water expected in the supply zone.
Sandton reservoirs and direct feeds
The following reservoirs and towers have improved slightly; however, they remain low:
- Linbro Park
- Marlboro
- Morningside
- Bryanston reservoir and Bryanston tower
Illovo reservoir and Illovo tower remain critically low.
Midrand systems update
Grand Central reservoir
The reservoir levels remained stable throughout the day and is supplying normally. However, this could decrease as demand increases during peak hours.
Grand Central tower
Pump resumed during the day and supplied to the tower zone. However, Johannesburg Water is monitoring closely.
Errand reservoir 1 and 2
Both reservoirs are critically low. Poor pressure to no water is expected in the supply zone.
Errand tower
Tower is critically low. Poor pressure to no water is expected in the supply zone. Johannesburg Water is monitoring closely.
President Park reservoir and tower
Critically low and poor pressure to no water is expected in the supply zone. The tower is empty and on bypass mode. Low pressure to no water is expected in the supply zone.
Alternative water supply has been arranged for the affected customers and will be placed at strategic locations.
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. This is to ensure that systems are kept stable throughout the coming months. We urge residents to report any form of vandalism and theft of water infrastructure to 0800 00 25 87.
