GAUTENG — Authorities have linked more than 400 illness cases in and around Bronkhorstspruit to a chlorination failure at the City of Tshwane's Bronkhorstspruit Water Treatment Works.
The outbreak has affected five communities and raised serious questions about municipal accountability. eNCA reported on 19 October 2026 that 408 cases of gastrointestinal illness were recorded between 7 and 18 October in the areas of Zithobeni, Bronkhorstspruit, Dark City, Rethabiseng and Sokhulumi.
Children under four years old make up the majority of those affected. No deaths have been confirmed.
What went wrong at the treatment plant?
Investigators found that the plant stopped chlorinating its water supply between 24 September and 14 October due to problems with the chlorine supplier.
The water source is also affected by ongoing sewage pollution. Laboratory analysis of patient samples detected Norovirus, Campylobacter and Shigella, though no cholera bacteria were found. Water tests returned extremely high levels of E. coli and total coliforms.
The City shut the plant down on 14 October, restored chlorine supplies, and brought it back online on 16 October. Despite this, authorities say the water remains unsafe for human use.
Warning issued to affected communities
Residents supplied by the plant have been instructed not to use tap water for drinking, cooking, bathing, brushing teeth, washing food or clothes, even after boiling.
Tap water may only be used for flushing toilets. The City is deploying a total of 36 water tankers to the affected areas, and residents have been urged to collect water from these tankers and store it in clean, covered containers.
The Water Research Commission is conducting independent tests, with initial results expected from Wednesday, 22 October. A full investigation into the cause of the contamination is due by 28 October, while health teams continue monitoring cases and running community education efforts.
South Africans reacted sharply to the news
