It was brought to the attention of the committee that about 9 wastewater treatment works discharge their 620 million liters per day of purified effluent into the Crocodile River, with very high loads of waste water effluents. These intensify the occurrence of blue-green algae or cyanobacteria. There is however, a remediation programme of the Hartbeespoort Dam in place. It focuses on management of phosphate through natural uptake in a food chain and re-establishing a biological balance within the dam waters using among other things, floating islands and removal of certain fish types.
