More than 400 people, most of them children under four, have fallen ill with stomach cramps and diarrhoea after drinking contaminated water in townships east of Pretoria, prompting authorities to declare the local tap water unfit for human consumption and to dispatch tankers with clean drinking water.

Residents in several townships east of Pretoria have been warned not to drink or cook with tap water after more than 400 people, mostly children under four, fell ill with stomach cramps and diarrhoea over a two-week period.

In a joint statement on Monday, South Africa's departments of water and health said 408 cases had been detected between 7 and 18 October across about five townships in Tshwane, the municipality that includes the capital. Lab tests indicate the illness was caused by residents being exposed to contaminated water from a local water treatment facility supplying several communities east of Pretoria, officials said. Samples tested positive for E. coli, norovirus, campylobacter, shigella and other pathogens that cause stomach cramps and diarrhoea. No deaths have been reported and no cholera bacteria has been found.

The water supplied to the area has been declared unfit for human consumption, and authorities urged residents to use it only to flush toilets. Tankers have been dispatched to supply clean drinking water. "Previously stored water should be discarded, and water containers must be disinfected using household bleach," officials said.

Early investigations found that local authorities had failed to warn residents about the contaminated water, according to the investigating team. The source of the outbreak remains unclear.

Tshwane has faced numerous outbreaks of waterborne disease in recent years. In 2023, 29 people were killed by a cholera outbreak in Hammanskraal, a township just outside Pretoria, linked to substandard water purification practices. In 2025, officials confirmed 48 cases of typhoid in the same area east of Pretoria.

Analysis

Why This Matters

The outbreak affects families with very young children, the group most vulnerable to dehydration from diarrhoeal illness, in communities east of Pretoria.
It is the latest in a string of waterborne disease outbreaks in Tshwane, pointing to ongoing problems with water treatment and municipal service delivery.
The finding that residents were not warned raises questions about how contamination alerts are communicated in future.

Background

Tshwane, the municipality around Pretoria, has experienced recurring outbreaks of waterborne disease. In 2023 a cholera outbreak in the Hammanskraal township outside Pretoria killed 29 people and was linked to substandard water purification practices. In 2025 officials confirmed 48 cases of typhoid in the same area. The current outbreak, with hundreds of cases across about five townships east of Pretoria, has been traced by lab tests to a local water treatment facility, but the specific source of contamination has not yet been identified. South African municipalities have faced longstanding difficulties maintaining aging water infrastructure and treatment plants, a broader context that has repeatedly featured in public debate over service delivery.

Key Perspectives

Health and water officials: They say lab tests show the illness came from contaminated water supplied by a local treatment facility. They have declared the supply unfit for human consumption, urged residents to use tap water only for flushing toilets, and dispatched tankers with clean drinking water. Residents: Hundreds of families, mostly with children under four, have reported stomach cramps and diarrhoea to local hospitals. They are being told to discard stored water and disinfect containers with household bleach while relying on tankers for drinking water. Critics and investigators: Early findings indicate local authorities failed to alert residents about the contaminated water before people fell sick. The source of the contamination remains unknown, and the pattern follows previous outbreaks in the same region linked to substandard purification.

What to Watch

Whether the contamination source at the treatment facility is identified and contained.
Whether case numbers rise beyond 408 or the first deaths are reported.
The findings of the investigation into why residents were not warned, and any action taken against the authorities responsible.
