Tshwane Faces Criminal Charges After Water Contamination Causes Widespread Illness
The South African Department of Water and Sanitation has initiated a criminal case against the City of Tshwane for providing misleading information regarding water quality. This follows a severe contamination crisis in Bronkhorstspruit, where the local water treatment plant operated without chlorination for 21 days, leading to nearly 600 reported cases of acute gastrointestinal illness. While chlorination was restored on 16 October 2026, independent testing indicates that tap water in affected areas remains unsafe for human consumption. The city is currently relying on water tankers while investigations by the Public Protector and the South African Human Rights Commission proceed.
Key points
- The Department of Water and Sanitation opened a criminal case against the City of Tshwane on 18 October 2026.
- Nearly 600 cases of acute gastrointestinal illness were recorded in Bronkhorstspruit and surrounding areas between 7 and 19 October 2026.
- The Bronkhorstspruit water treatment works operated without chlorination for 21 days, from 23 September to 14 October 2026.
- Tests at the Fountains water treatment works in Pretoria also revealed E. coli levels exceeding national standards due to a lack of disinfection.
- Residents are advised to boil tap water until further notice, though current testing suggests it remains unsafe for consumption.
What happened
The Department of Water and Sanitation (DWS) has launched a criminal investigation into the City of Tshwane for failing to provide accurate information regarding the safety of its water supply. Deputy Minister David Mahlobo confirmed the legal action on 18 October 2026, citing the city's failure to maintain essential chlorination processes at its treatment facilities.
The crisis reached a peak in Bronkhorstspruit, where the local water treatment works operated without chlorination for 21 days. Health Minister Aaron Motsoaledi reported that 595 cases of acute gastrointestinal illness were recorded in the area between 7 and 19 October 2026, including 262 children under the age of five. Pathogens identified in stool tests include Norovirus, Campylobacter, Shigella, and Sapovirus.
Context
The contamination issues extend beyond Bronkhorstspruit. An inspection of the Findlay Reservoir at the Fountains water treatment works in Pretoria on 21 October 2026 found that water was not being disinfected, with E. coli levels exceeding national standards. The reservoir has since been emptied, and the city is sourcing water from Rand Water.
City officials attributed the chlorination failure to a shortage of chemicals, with Mayor Nasiphi Moya describing the situation as indefensible. While the city initially cited a 40% price increase for chlorine, the mayor later noted that costs had increased fourfold. The plant manager has been suspended, and the city is currently seeking alternative suppliers to address the ongoing supply chain challenges.
What's next
Residents and businesses in affected areas are advised to continue boiling tap water until further notice. Independent testing by the Water Research Commission across 40 sampling sites indicates that while water quality is showing signs of improvement, it remains unsafe for human consumption and should be restricted to tasks such as flushing toilets.
The DWS is continuing its engagement with the National Prosecuting Authority regarding potential additional charges. Furthermore, the Public Protector has launched an investigation into the crisis, and the department is coordinating with the South African Human Rights Commission to address the systemic failures in water management.
Why it matters
The crisis highlights a critical failure in municipal water infrastructure, leaving nearly 600 people ill and prompting criminal charges against the city.
