The metro recently conducted an investigation to determine the source of an unnatural bluish-green substance that was spotted flowing into the dam at the intersection of Rondebult and Yaldwyn roads last month.
According to metro spokesperson Themba Gadebe, the source of the pollution was identified as a sewer pump station that had failed.
“The contractors were on site working around the clock to fix the pump station,” said Gadebe.
On August 2, the pump station was fixed. Monitoring of the pump stations is an ongoing exercise, said Gadebe.
“Furthermore, it must be noted that factories within the jurisdiction of the City of Ekurhuleni are subjected to the City’s by-laws, which require that they have a permit in order to discharge industrial effluent into the sewer system,” Gadebe said.
Gadebe said the metro would take samples to evaluate the extent of the pollution and its effects.
