Businesses across Gauteng face renewed uncertainty over water supply after Rand Water warned that rising consumption was putting pressure on its bulk water network, increasing the risk of disruptions if demand is not brought under control.
On 20 October 2026, Rand Water said it was pumping at maximum capacity, but consumption continued to rise. The utility urged municipalities to reduce usage in line with their allocated volumes and warned that supplies could be curtailed to customers exceeding their limits.
Rand Water spokesperson Makenosi Maroo said immediate action was needed to protect the system.
“Immediate compliance is essential to avert the risk of system failure and protect continuity of supply,” Maroo said.
The warning raises concerns for businesses that rely on consistent water supplies to maintain production, hygiene and customer service. Restaurants, laundries, manufacturers and other water-intensive enterprises can face additional expenses or interruptions when supply becomes unreliable.
The extent of the impact depends on each business’s water requirements, the duration of interruptions and whether alternative storage or supply arrangements are available.
Johannesburg Water urges conservation
Johannesburg Water issued a further appeal on 21 October, saying high consumption was putting pressure on the bulk supply system and affecting reservoirs and water towers.
The utility urged residents and businesses to reduce consumption, avoid using drinking water for non-essential activities and comply with Level 1 water restrictions.
The measures include restrictions on garden watering and swimming pool filling between 06:00 and 18:00, as well as requirements to wash cars with buckets rather than hosepipes.
Johannesburg Water also announced targeted supply restrictions in areas experiencing high water losses, excessive wastage and low payment levels. Affected areas would be communicated through ward councillors and the utility’s communication channels.
The measures could require some businesses to adjust water use and operating practices, although the utility has not quantified their likely financial impact on commercial customers.
Reported losses highlight business risks
DA Gauteng infrastructure spokesperson Nico De Jager said one business in Founders View had suffered losses exceeding R1 million over three months because of recurring water interruptions.
He also described a business that reportedly went without water for at least 48 hours despite logging and escalating service requests.
The business was not identified, and the reported losses have not been independently verified for this article.
“For businesses, a dry tap is not only an inconvenience,” De Jager said. “It costs money.”
He called for a funded infrastructure recovery plan prioritising maintenance, infrastructure renewal and capital investment.
The reported losses illustrate the potential financial exposure businesses face when water interruptions affect trading hours or operations. However, available information does not establish how widespread such losses are across Gauteng.
Businesses may use storage tanks, alternative supplies or changes to operating schedules to manage interruptions, but these measures can involve additional costs and may not be practical for every operator.
Rand Water has urged municipalities to bring consumption within allocated volumes, while Johannesburg Water has called for conservation and targeted measures to reduce pressure on its network.
