Deputy President calls for urgent, coordinated action as treatment works remains shut, private water tankers face scrutiny, while Pretoria CBD’s boil water advisory is lifted and Hammanskraal’s deadly cholera outbreak remains a warning about failing water infrastructure
South Africa’s Deputy President, Shipokosa Paulus Mashatile, visited Bronkhorstspruit on Monday to assess a water contamination crisis that has left hundreds of residents ill, as authorities reported a sharp increase in gastrointestinal illness cases and intensified efforts to restore a safe and reliable water supply.
Mashatile, who chairs the Inter Ministerial Committee on Water and Sanitation, visited the Bronkhorstspruit Water Treatment Works and Bronkhorstspruit District Hospital, where he received updates on the condition of hospitalised patients and the response by health authorities. His visit brought senior national, provincial and municipal officials together at a time when the treatment works remains closed and emergency water deliveries have become essential for affected communities.
The crisis has grown substantially since the government initially reported 408 cases of gastrointestinal illness between 7 and 18 October. By 26 October, news reports citing officials put the number at 833, with Water and Sanitation Minister Pemmy Majodina reporting 27 new cases in the preceding 24 hours. Children accounted for about 40% of patients, according to reports from the ministerial briefing.
The outbreak has been linked to water supplied by the City of Tshwane’s Bronkhorstspruit Water Treatment Works, which operated without chlorination for an extended period while drawing raw water from a river affected by sewage pollution. The treatment works was subsequently shut down as authorities investigated the contamination, provided alternative water supplies and worked to restore the plant’s ability to produce safe drinking water.
The safety of our communities must come first. Every intervention must be guided by the protection of human life, accountability and the urgent restoration of access to safe and reliable water.
The Deputy President’s visit came amid mounting scrutiny of the municipality’s water management systems, the failure to maintain disinfection, the speed of public warnings and the condition of wastewater infrastructure upstream of the affected treatment plant.
Accompanied by Water and Sanitation Minister Pemmy Majodina, Deputy Minister David Mahlobo, Gauteng MEC for Infrastructure Development and Cooperative Governance and Traditional Affairs Jacob Mamabolo, and Tshwane Executive Mayor Dr Nasiphi Moya, Mashatile visited the treatment works to assess the situation and engage officials on the interventions required to restore a safe supply.
He also visited Bronkhorstspruit District Hospital to receive updates on patients and the healthcare response to the reported outbreak.
The visit was conducted under the mandate of the Inter Ministerial Committee on Water and Sanitation, which coordinates government interventions relating to water and sanitation challenges, service delivery and accountability.
The scale of the reported illness has made the crisis a matter of national concern rather than a problem confined to municipal water operations. It has required coordination between the City of Tshwane, the Gauteng provincial government and national departments responsible for water, sanitation and public health.
The immediate priorities are to provide communities with safe water, ensure that people who develop symptoms receive medical attention, establish the extent of contamination, and determine when the treatment works can safely return to service.
The Bronkhorstspruit Water Treatment Works has remained shut down while authorities undertake cleaning, disinfection and water quality testing. The shutdown has forced the City to rely on alternative supplies, including tankers transporting water from the Cullinan Water Treatment Works.
The municipality has increased its emergency water delivery capacity, with the government’s visit programme highlighting the addition of a 34,000 litre tanker. Coca Cola Beverages South Africa also donated a water tanker to support emergency deliveries to affected communities. The tanker was received by Majodina, Mahlobo, Mamabolo and Moya following the meeting.
The donation provides additional logistical support at a time when households need dependable access to drinking water.
Authorities have said that water supplied to residents, including water transported by private tanker operators, must meet the required safety standards before being distributed for consumption.
Mashatile has expressed concern about private suppliers whose water sources may not be adequately documented or independently verified. He said government intervention would be needed to check these supplies, while the City continued providing water to residents.
The concern is significant because an emergency tanker can protect public health only if the water it carries is safe at the source, handled hygienically during transport and delivered in a way that prevents contamination. Residents should follow official instructions on approved collection points and avoid assuming that all water sold or delivered privately is safe to drink.
The City has said the alternative water supplied through its emergency arrangements has been tested and is safe to drink. Monitoring and oversight remain necessary as the number of deliveries increases and more providers may be involved.
The Department of Water and Sanitation’s investigation found that the Bronkhorstspruit Water Treatment Works operated without chlorination from late September until its shutdown in October. Parliament was told that disruptions involving the chlorine supplier contributed to the interruption in disinfection. The plant continued drawing water from the Bronkhorstspruit River during this period, despite pollution concerns.
Chlorination is a key barrier against harmful microorganisms in drinking water. Where raw water is affected by sewage, inadequate disinfection can allow disease causing organisms to survive treatment and enter distribution networks.
The government’s investigation also identified serious contamination in water samples taken from the treatment works and reservoirs serving the affected communities. E. coli and total coliform bacteria were found at very high levels in samples collected during the crisis. These findings supported the assessment that contaminated water was a likely common source of exposure for the reported illnesses.
Laboratory analysis of patient samples identified several gastrointestinal pathogens, including norovirus, Campylobacter and Shigella. No cholera bacteria were detected in the stool specimens analysed in the initial government report. The current Bronkhorstspruit outbreak should therefore not be described as a cholera outbreak unless health authorities provide evidence establishing that diagnosis.
The case total has risen as additional patients have been identified and reported. The 408 cases announced for the period from 7 to 18 October were an earlier snapshot of the investigation.
On 26 October, reporting from the National Water Crisis Committee briefing indicated that Tshwane had secured sufficient chlorine for the immediate period ahead, with the available supply expected to last approximately six to seven weeks. The treatment works, however, remained closed while the authorities continued the work required to restore safe operations.
The reported restoration of chlorine availability is an important operational development, but obtaining a disinfectant supply is not the same as certifying the entire treatment system as safe. Before the plant can resume normal distribution, authorities must be satisfied that the infrastructure is functioning properly, the treatment process is effective and the water meets the required quality standards.
Officials must also establish why the supply interruption was not resolved before inadequately disinfected water reached households, what procedures were followed when the chlorine supply became uncertain, and why residents were not warned sooner.
The City has launched an investigation into the incident, and the manager of the treatment works has been suspended pending further inquiry. The suspension is an interim administrative measure, not a finding of guilt. Responsibility for the failure must be determined through evidence, including the procurement arrangements, operational records, escalation procedures and communication between the plant and municipal management.
The crisis cannot be understood solely as a shortage of chlorine. The Bronkhorstspruit Water Treatment Works draws raw water from the Bronkhorstspruit River, which official investigations have identified as being affected by pollution.
The Department of Water and Sanitation linked the contamination concerns to dysfunctional wastewater treatment infrastructure in the neighbouring Victor Khanye Municipality, including problems at treatment works serving Delmas and Botleng. Investigators also identified malfunctioning sewage pump stations in Tshwane, alongside other possible sources of pollution.
Such failures can place additional pressure on a drinkingbwater treatment plant, especially when raw water quality is poor. A functioning treatment system must be able to manage the quality of the water entering it, apply the required treatment processes and verify the quality of the water leaving the plant.
The wider picture also raises questions about maintenance, wastewater compliance and the condition of municipal infrastructure across administrative boundaries. Pollution originating upstream may affect communities supplied downstream, requiring coordination between municipalities and water authorities.
The Department of Water and Sanitation has previously raised concerns about water and sanitation compliance in municipalities. The 2026 crisis has renewed attention on the consequences of delayed maintenance and inadequate coordination between water treatment, wastewater management and public health systems.
The Bronkhorstspruit incident has placed Tshwane’s water management procedures under intense scrutiny. Moya has acknowledged that the treatment works should not have continued supplying water without adequate chlorination and has accepted overall political responsibility for the City’s response, while insisting that administrative accountability must also be established.
The investigation is expected to examine procurement, operational and management processes, including the handling of the chlorine supply interruption and the communication of risks to residents.
A central question is whether the City had effective contingency arrangements to prevent a supply dispute or delivery problem from interrupting a critical water treatment process. Another is whether the risks were escalated quickly enough and whether the public was given timely and sufficiently clear instructions.
The Deputy President’s visit adds national level oversight to an investigation that must still establish the facts. Public confidence will depend on the transparency of the findings and on whether corrective measures are implemented, rather than on official visits and announcements alone.
The Bronkhorstspruit crisis has coincided with a separate water safety incident in Pretoria’s central business district. On 24 October, Moya announced that the City had lifted a boil water advisory affecting Pretoria CBD and surrounding areas supplied through Findlay Reservoir after laboratory testing found no detectable E. coli or total coliform bacteria.
The contamination had been identified in groundwater supplied by the Fountains springs. The City said a damaged sewer pipe in Groenkloof was associated with the contamination of the groundwater source feeding the affected supply system.
Municipal teams isolated the affected source, switched the area to an alternative supply from Salvokop Reservoir, cleaned Findlay Reservoir, applied chlorine shock treatment to the distribution network and carried out further tests. The latest satisfactory results allowed the precautionary advisory to be withdrawn.
“Residents may therefore resume normal use of their tap water without boiling it,” Moya said in the City’s statement.
The mayor also acknowledged that the initial warning had been communicated too late. “The delay in communicating the initial boil-water advisory was unacceptable, and I sincerely apologise to affected residents,” she said.
Repairs to the damaged sewer pipe remain outstanding. The groundwater source is to remain isolated until testing confirms that the contamination has been eliminated, after which the pipeline will be flushed before the source is restored.
The City has stated that the Pretoria incident is unrelated to the Bronkhorstspruit crisis. Although both cases raise questions about municipal water safety, their causes and circumstances must be examined separately. The Pretoria case concerns groundwater contamination associated with a damaged sewer pipe; the Bronkhorstspruit case involves an extended interruption in chlorination, polluted raw water and a wider treatment-system failure.
Moya has said the Pretoria incident will be included in the broader independent investigation into municipal water management, particularly the delayed public warning.
The current events have revived memories of the deadly cholera outbreak that affected Hammanskraal in 2023. That crisis exposed serious deficiencies in water and sanitation infrastructure and raised questions about the reliability of drinking water treatment and municipal oversight.
During the outbreak, the Department of Water and Sanitation raised concerns about water quality supplied to Hammanskraal and linked longstanding problems in the area to pollution associated with the Rooiwal Wastewater Treatment Works. Treated wastewater from Rooiwal enters the Apies River, which flows towards Leeukraal Dam. The City’s Temba Water Treatment Works draws raw water from the dam for treatment before distribution.
Government investigations found serious shortcomings at both Rooiwal and Temba. The wastewater treatment works was failing to meet the required standards for treated wastewater discharged into the environment, while testing during the crisis found that drinking water supplied from Temba did not meet the applicable quality requirements.
The City was instructed to stop supplying the affected water for human consumption and to provide safe alternatives, including water delivered by tankers.
The outbreak caused deaths and hospitalisations. The figures reported at different stages varied according to the dates and geographical areas covered. The World Health Organization’s retrospective account recorded 1,290 suspected cases, 199 confirmed cases and 47 deaths nationally by August 2023. These were national figures and should not be confused with totals for Hammanskraal alone.
The independent Water Research Commission investigation documented serious faecal pollution and non compliance at the Rooiwal and Temba facilities. It did not, however, conclusively establish the precise source of the cholera outbreak. The presence of polluted water and failing treatment infrastructure demonstrated substantial public-health risks, but did not by itself prove the exact route through which the cholera bacteria reached infected people.
Mashatile’s visit signals the seriousness with which the national government is treating the Bronkhorstspruit crisis. His call for urgent and coordinated action places public health, reliable water access and accountability at the centre of the response.
Yet the central challenges remain operational. The treatment works must be safely restored, alternative water must continue to reach affected households, private suppliers must be checked, and the investigations must determine how a critical disinfection process was allowed to fail.
In Pretoria CBD, the lifting of the boil water advisory is a positive immediate development, but repairs to the sewer pipe and testing of the affected groundwater source remain necessary. In Hammanskraal, the history of cholera and infrastructure failure illustrates why short term interventions must be matched by sustained investment and independent monitoring.
The three incidents are not evidence of one common cause. They do, however, raise a shared question about the ability of public institutions to maintain essential infrastructure, detect hazards, communicate risks and protect residents before a technical failure becomes a public health emergency.
For communities that depend on municipal water, the measure of success will not be the number of official visits or the volume of emergency tankers delivered. It will be whether safe water flows consistently from the tap, whether failures are disclosed promptly and whether those responsible for preventing and managing the crisis are held accountable on the basis of established evidence.
