Rand Water is experiencing water supply challenges due to power failures and high water consumption during the heatwave.

Maximum water treatment capacity of its purification plants in Zuikerbosch and Vereeniging is 5 000 Mega litres of water a day.

Water reservoir storage declining

Rand Water pumps purified water from its purification works to their pump stations that then pumps water to 59 water storage reservoirs.

Municipalities then receive water to distribute to residents.

On 8 January the total reservoir storage level was 76%.

Due to high water abstraction by municipalities in the reservoirs, this level began to decline significantly on 9 January.

Power outages affect water supply

On 13 January, power outages at the Zuikerbosch purification plant and the Eikenhof pump station exacerbated the situation.

The power outage lasted six hours and affected the Zuikerbosch pumping station at Engine Room 4.

This station supplies nearly 40% of capacity.

This impacted pumping to pump stations, which feed water into reservoirs.

For three hours, the system could not feed water into the reservoirs due to a power outage at the Eikenhof booster station.

Rand Water’s system is susceptible to power outages and can take up to four hours to recover after one.

When the system recovered, the reservoir storage level had dropped to 63%.

Municipalities asked to reduce consumption

The drop in reservoir water storage level prompted Rand Water to request that municipalities reduce their consumption to keep as much water in the reservoirs as possible.

 This is to prevent the system from collapsing and becoming nearly impossible to recover from.

This, however, did not help because high-water abstraction continued to deplete reservoir storage levels.

The Eikenhof booster station experienced yet another power outage on Sunday, 29 January at 4:30.

This affected water pumping from this station.

This incident resulted in further depletion of Rand Water’s reservoir levels, with some reservoirs reaching 0% storage capacity.

Rand water completing generation installation project

Rand Water is nearing the end of a generator installation project aimed at reducing power outages.

However, generator capacity will not be sufficient to cover all Rand Water sites.

Power outages continue to be one of the most serious threats to the stability of Rand Water’s networks, affecting continuous water supply to municipalities.

Rand Water systems have begun to stabilise pumping at full capacity.

Full recovery will be dependent on less frequent power outages.

All customers are encouraged to use water wisely in order to help the system fully recover.
