Systems Update
Alexander Park reservoir
There is currently high demand on the reservoir, which has decreased the storage levels. As an intervention, the reservoir is being throttled overnight to build capacity. As a result, poor pressure can be expected during this time.
Eagles Nest reservoir
The reservoir levels have declined compared to the previous week. However, mitigation strategies are ongoing to try augment and retain capacity. Customers in this supply zone may be affected by low pressure, especially in high-lying areas.
Soweto system
Although interventions are in place to curb the high demand and build capacity, the Doornkop reservoir is still low. Customers in this supply zone may experience poor pressure, particularly in high-lying areas. The Jabulani reservoir continues to supply on bypass, while the rest of the Soweto systems are stable.
However, demand is still on high on the overall Meredale system, specifically in Soweto areas. Customers are requested to lower consumption and repair leaks in their properties as these also contribute to high demand. Areas supplied by the following reservoirs will have low water pressure: Doornkop West, Protea Glen, parts of Meadowlands, and Zondi reservoirs.
Midrand
The water levels at the Development Bank reservoir have declined compared to last week. This may result in poor pressure, particularly in high-lying areas. The other reservoirs in the Midrand system are stable.
Commando System
Although supply has increased between yesterday and today, demand on the system is still high. The Crosby reservoir declined compared to last week. The Hursthill 1 reservoir is critically low, while Hursthill 2 remains low. Poor pressure to no water can be expected in parts of the supply zone. As part of Johannesburg Water’s intervention, Hursthill 1 reservoir has been reconfigured to boost supply. Hursthill 2 will be closed overnight to build capacity.
The following reservoirs will either be closed or throttled to 90% overnight (between 21:00 and 04:00) to retain water and build capacity for the next day:
• Soweto: Doornkop West
• Commando: Brixton and Hursthill 2
• Alexandra Park
• Deep South: Orange Farm reservoir 2, Lenasia high-level, Lenasia Hospital Hill, Lawley
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.
