Systems Update
Johannesburg Water has observed a high demand across the system, which has affected the bulk supply. Rand Water reservoirs remain low, although they are pumping normally.
Sandton systems
The Sandton system remains under pressure, with most reservoirs being at low levels. The Illovo reservoir is critically low, while the tower is empty. Residents in this supply zone have poor pressure to no water and water tankers have been deployed to the affected areas. As a mitigation strategy, Johannesburg Water has closed the outlet of the reservoir to build capacity. The Morningside, Linbro Park, Bryanston, and Marlboro reservoirs are currently low but supplying normally. High-lying areas in the Bryanston supply zone may experience low pressure to no water. Alternative water supply through water tanker services is ongoing. Johannesburg Water is monitoring the situation.
Soweto Systems
The Soweto systems remained stable during the day under the heatwave conditions but will be affected by overnight throttling (reducing pressure and flow). The bulk supply from Rand Water is also currently 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 currently have no water supply. Alternative water supply is being provided to affected areas.
Midrand Systems
Most Midrand systems are currently stable; however, the Rabie Ridge reservoir is experiencing high demand and water levels are currently low 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. As a mitigation strategy, Midrand reservoirs will be throttled overnight to build capacity for tomorrow.
Alexander Park reservoir
There were some overnight improvements at the reservoir, however, due to high demand, the levels have dropped and are currently low. The outlet was closed overnight to build capacity and was reopened this morning. However, customers in this supply zone will have poor pressure to no water supply, particularly in high-lying areas. Alternative water supply will be provided to affected areas.
Crown Gardens reservoir
The reservoir is currently stable but experiencing high demand, which is placing strain on the incoming supply. Johannesburg Water will continue to throttle the reservoir outlet overnight to build capacity for tomorrow.
Eagles Nest reservoir
The reservoir is critically low due to increasing demand and poor supply pressure. Poor pressure is expected in high-lying areas; however, system has been reconfigured to boost the supply. Johannesburg Water is also monitoring the impact on the Alan Manor and Naturena reservoirs (which are supplied by the Eagles Nest reservoir).
South Hills tower
The tower is critically low due to poor supply pressure and there is currently one pump operating. Poor pressure to no water is expected in the supply zone, especially in high-lying areas. Johannesburg Water will monitor the system closely throughout the day.
Linden 1 reservoir and tower
The reservoir level remains low but is supplying normally. While the outlet is fully opened, poor pressure can be expected in high-lying areas of the supply zone. The tower improved overnight, and supply is normally, however the levels are low due to high demand and poor supply. Johannesburg Water will monitor the situation.
Commando System
• Brixton reservoir: The reservoir improved overnight and is supplying normally.
• Brixton tower: The tower is stable and is supplying normally.
• Hursthill 1 and 2 reservoirs: Both reservoirs are critically low and poor pressure to no water is expected in the supply zones. However, the outlets to both reservoirs are fully opened. Hursthill 1 reservoir has been configured to boost supply, while Hursthill 2 reservoir outlet will be closed overnight to build capacity for tomorrow.
• Crosby reservoir: The reservoir is critically low, however the outlets are fully open and supplying normally, while the outlets are fully opened. Poor pressure to no water is expected in the supply zone.

Systems Update
Johannesburg Water systems under severe strain due to high demand and recent heatwave
High demand due to the hot weather temperatures in the past week has led to some of Johannesburg Water’s systems coming under severe strain: the South Hills tower, the Alexander Park reservoir, as well as two Sandton direct feeds. This has also had a negative impact on bulk supplier, Rand Water’s reservoir levels, which are currently low. Although Rand Water is pumping and supplying, the increased demand on the entire system has resulted in reservoirs being unable to maintain capacity.
Daleside pumpstation
Following the power trip at Rand Water’s Daleside pumpstation which occurred on Tuesday, 5 December, Johannesburg Water systems were left at critically low levels. Although pumping was restored on Tuesday night, both the Ennerdale and Orange Farm reservoirs are low, while the Lawley reservoir is critically low. Customers in these supply zones will experience poor supply pressure.
South Hills tower
The South Hills tower did not pump overnight due to low tower levels, leading to the tower becoming low. However, pumping resumed in the morning and low flows are coming from the tower. Customers in this supply zone may experience poor pressure to no water, particularly in the high-lying areas.
Alexander Park reservoir
Alexander Park reservoir is critically low. Supply pressure is low, due to poor incoming supply. The outlet was closed overnight to build capacity and has been reopened this morning. However, customers in this supply zone will have poor pressure to no water supply, particularly in high-lying areas.
Sandton systems
As part of a water demand management strategy, Rand Water closed the Sandton supply, impacting the Marlboro and Linbro Park direct feeds, which may cause reduced pressure for the customers in the supply zones. However, Johannesburg Water closed the outlets overnight in order to retain some capacity. The bypass will also be opened in order to mitigate the strain on the systems. Alternative water supply will be arranged should the need arise. Please note that it can take several hours for systems to fully recover after being reopened.
Eagles Nest reservoir
The reservoir is critically low due to poor supply. Poor pressure is expected in high-lying areas. Johannesburg Water is also monitoring the impact on the Alan Manor and Naturena reservoirs (which are supplied by the Eagles Nest reservoir).
Alternative water supply is being arranged through water tankers for the affected areas.
Johannesburg Water will monitor the above systems throughout the day.
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.

Systems Update
Johannesburg Water systems still under immense pressure due to demand outstripping supply
Due to the intense heat over the last week, there has been a significant demand on several of Johannesburg Water’s systems. This has also had a negative impact on bulk supplier, Rand Water’s reservoir levels, which are currently low. Although Rand Water is pumping and supplying, the increased demand on the entire system has resulted in reservoirs being unable to maintain capacity.
Sandton systems
Most reservoirs are currently low, while the Illovo reservoir and tower are empty. Residents in this supply zone have no water supply and water tankers have been deployed to the affected areas. The Morningside, Linbro Park and Bryanston reservoirs are also on a downwards trend with low levels while the Marlboro reservoir levels are also declining. Although the bypass mode has been activated, it is not delivering enough to replenish the Sandton systems as required. There is currently no estimated time for recovery and Johannesburg Water continues to monitor the situation.
Soweto Systems
The Soweto systems remained stable during the day under the heatwave conditions but will be affected by overnight throttling (reducing pressure and flow). The bulk supply from Rand Water is also currently 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.
Midrand Systems
Most Midrand systems are currently stable; however, they are on a downwards trend due to increasing demand. The Rabie Ridge reservoir is experiencing high demand and water levels are low. The reservoir is currently supplying at 30% while the tower remains on bypass mode. Poor pressure can be expected in parts of the supply zone. As a mitigation strategy, Midrand reservoirs will be throttled overnight to build capacity for Thursday.
Alexander Park reservoir
Alexander Park reservoir is critically low due to increasing demand. The outlet was closed overnight to build capacity and was reopened this morning. However, customers in this supply zone will have poor pressure to no water supply, particularly in high-lying areas.
Crown Gardens reservoir
The reservoir is currently stable but on a downwards trend due to high demand, which is placing strain on the incoming supply. Johannesburg Water will throttle the reservoir overnight to build capacity for Thursday.
Eagles Nest reservoir
The reservoir is critically low due to increasing demand. Poor pressure is expected in high-lying areas. Johannesburg Water is also monitoring the impact on the Alan Manor and Naturena reservoirs (which are supplied by the Eagles Nest reservoir).
South Hills tower
Due to poor incoming supply caused by high demand, the South Hills tower did not pump overnight. However, pumping resumed in the morning and low flows are coming from the tower. Customers in this supply zone may experience poor pressure to no water, particularly in the high-lying areas.
Linden 1 reservoir and tower
The reservoir is critically low. While the outlet is fully opened, poor pressure can be expected in high-lying areas of the supply zone. Johannesburg Water is also monitoring the impact at the Blairgowrie reservoir. The tower is critically low to empty and poor pressure is expected in the supply zone.
Aeroton reservoir
The reservoir is currently stable but on a downwards trend due to increasing demand. Johannesburg Water is monitoring the impact on the supply zone, including the Orlando East reservoir (Aeroton reservoir feeds into the Orlando East reservoir).
