Planned work on Rand Water’s Palmiet and Zuikerbosch systems from 29 May to 2 June will affect 69 Tshwane reservoirs. The city has activated an emergency plan and is asking residents to cut their water use sharply.
Residents across large parts of Tshwane should prepare for low water pressure and interruptions from Friday 29 May to Tuesday 2 June 2026. Rand Water and Eskom will carry out planned maintenance on the Palmiet and Zuikerbosch water systems, two key parts of the bulk network that supplies Gauteng. The City of Tshwane says the work will affect supply to 69 reservoirs in Regions 1, 2, 3, 4 and 6, and has activated an emergency coordinated response plan to limit the impact.
Why the shutdown is happening
Rand Water’s system moves water from the Vaal Dam through treatment works and booster pump stations to municipal reservoirs across the province. Zuikerbosch, near Vereeniging, is one of its largest treatment works, and Palmiet is a key pumping station in the system that carries water north. Like any large infrastructure, these facilities need regular maintenance, and some of that work can only be done when parts of the system are taken out of service. Eskom’s involvement reflects the fact that the pump stations depend on reliable high-voltage electricity supply.
The city describes the shutdown as part of broader efforts to strengthen long-term water security and infrastructure resilience. Planned maintenance is far preferable to the unplanned failures that have caused so many outages elsewhere in Gauteng. But in a system already running close to its limits, even a planned shutdown can push reservoirs to empty.
What the city is doing
Utility Services MMC Frans Boshielo announced the city’s plan in a statement this week. Reservoirs are being filled to maximum capacity before the shutdown begins. Outlet valves in selected areas are being throttled to limit consumption and stretch the stored water further. Demand management measures will be stepped up as the system comes under pressure.
The city has also set up an Emergency Shutdown Operations Centre to monitor reservoir levels in real time and send water tankers to high-demand and affected areas. It is procuring 181 additional tankers to supplement its own fleet of 36. Teams will remain on the ground throughout the maintenance period, and the city has thanked residents in advance for their patience and cooperation.
The University of Pretoria has also warned students and staff of possible disruptions across its campuses and residences from 29 May to 3 June.
Recovery takes time
The city has warned that some areas may take longer to recover after the work ends, and that some reservoirs will need extra time to return to normal levels. This matches what Rand Water’s chief executive, Sipho Mosai, told the Human Rights Commission’s water inquiry only last week: high-lying areas often take longest to recover after maintenance, because water must be pumped uphill and reservoirs at the top of the system are the last to refill.
That is why the period after the shutdown can be as difficult as the shutdown itself. If demand surges as soon as supply returns, reservoirs that are trying to refill can be drained again before they recover, prolonging the disruption.
What residents can do
The city’s main request is that residents drastically reduce their water use during the shutdown, to help stabilise supply and avoid system collapse in vulnerable areas. In practice, that means storing enough drinking water for a few days before Friday, postponing laundry, car washing and garden watering, taking short showers instead of baths and fixing any leaks at home. Households with boreholes or rainwater tanks can ease the pressure by using those for non-drinking purposes.
Residents should also keep an eye on the city’s official channels for updates on affected areas and tanker locations, and report burst pipes or empty reservoirs promptly.
A test of planning
The shutdown is an important test of how well Gauteng’s municipalities can manage planned disruptions. Tshwane appears to have prepared seriously, with filled reservoirs, a dedicated operations centre and a large tanker fleet on standby. The city’s non-revenue water, at around 44 percent, means that a great deal of its water is still lost through leaks and illegal connections, which reduces the buffer it has during events like this.
If the plan works and supply recovers quickly, it will show that careful coordination between Rand Water, Eskom and the municipality can keep disruption to a minimum. If reservoirs run dry and recovery drags on for days, it will add to the case that Gauteng’s water network has too little margin to absorb even routine maintenance. Either way, the next five days will reveal a great deal about the resilience of the system Tshwane depends on.
