Much of the oil flowed into the Baynespruit River, downstream into the uMsunduzi and uMgeni rivers all the way down to Inanda Dam.
The spill resulted in thousands of dead fish as far as 40km downstream from the factory.
Willowton Group said that the river and banks were cleared of visible product and that there was only a skeleton clean-up team on the river doing routine maintenance.
The company said Dr Mark Graham from GroundTruth was deployed to assist, and that a drone was used along the river specifically targeting inaccessible areas which clean-up teams could not get to.
