Due to the intense heat over the last week, Johannesburg Water says there has been a significant demand on several supply systems.
JOHANNESBURG WATER EXPLAINS SUPPLY CRISIS
“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 increase on the entire system has resulted in reservoirs being unable to maintain capacity.”
Johannesburg Water elaborates on the current state of its systems:
Most reservoirs are currently low, while the Illovo reservoir and tower are empty. Residents in the 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 downward trend with low levels while the Marlboro reservoir levels are also declining.
The Soweto systems remained stable during the day under the heat wave 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.
Most Midrand systems are currently stable; however, they are on a downward 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.
Alexander Park reservoir
The 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 Garden reservoir
The reservoir is currently stable but on a downward trend due to high demand which is placing strain on the incoming supply.
Eagle Nest reservoir
The reservoir is critically low due to increasing demand. Poor pressure is expected in high-lying areas. Johannesburg Water is monitoring the impact on the Alan Manor and Naturena reservoirs.
South Hills tower
Due to poor incoming supply caused by high demand, the South Hills tow did not pump overnight. However, pumping resumed in the morning and low flows are coming from the tower.
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.
The reservoir is currently stable but on a downward trend due to increasing demand. Johannesburg Water is monitoring the impact on the supply zone, including the Orlando East reservoir.
