According to the City of Johannesburg and Tshwane, the lengthy power outages have put a strain on their water towers, and the sweltering heat have boosted demand for water.
Reservoirs, according to both metros, are not filling up quickly enough.
Eskom has instituted power outages in order to prevent a potential collapse of the energy system, but these outages have had an impact on services, notably water supplies.
To feed the water towers in the metropolis, several water pump stations in Johannesburg and Tshwane require a steady supply of energy.
Sipho Stuurman, a spokesman for the City of Tshwane, stated that households must abide by level 1 limitations and cut back on usage in order to ensure a constant water supply.
In especially in high-lying regions, “continuous load shedding is harming us and is going to undermine our capacity to ensure that water is supplied,” Stuurman added.
As more people turn to fans and air conditioners to stay cool during the hot weather, pressure is also likely to build up on the grid.
