Nine protesters appeared in the Bushbuckridge Magistrate's Court on Wednesday on charges of public violence and arson, Mpumalanga police said.
Lieutenant-Colonel Leonard Hlathi said they each received R1000 bail and the matter was postponed to May 31.
“Two minors were also arrested on Monday, but they have since been released into the custody of their parents,” he said.
On Monday, protesters in Lilydale burnt municipal offices and a grader. They were unhappy that drinking water in the area had been found unfit for human consumption.
According to the 2012 Blue Drop Report, the water of 14 municipalities, including Bushbuckridge, did not meet government standards.
Residents were advised to treat the water by boiling it or adding bleach before drinking it.
Hlathi said the situation on Wednesday was quiet and no incidents of violence had been reported. - Sapa
