Durban experiences water disruptions due to increase in algae volumes
An increased volume of algae has been found at the Albert Falls, Nagle and Inanda dams.
THE excess algae in water dams has led to a negative effect on the amount of water that can be treated at the Durban Heights Waterworks.
This has been confirmed by uMngeni-uThukela Water today, Monday afternoon. Siyabonga Maphumulo of uMngeni-uThukela Water says they have noted an increased volume of algae at the Albert Falls, Nagle and Inanda Dams.

“As a result, some areas of eThekwini that are supplied by the Durban Heights Water Treatment Works are experiencing water disruptions. While the Waterworks is still producing potable water of excellent quality standards, the production capacity has decreased due to increased desludging and the frequent need to backwash filters to get rid of the algae,” says Maphumulo.
He highlighted that the organisation is continuing with efforts to optimise its treatment processes. Maphumulo adds, “This includes using advanced chemical treatment methods to unclog its filters. Our water quality monitoring has also been increased in order to detect and act against the presence of algae in raw water from the Albert Falls-Nagle Dam system.”
He says they are continuing to monitor the raw water. “We anticipate that the problem will be resolved once the algal count from Albert Falls-Nagle Dam subsides,” Maphumulo concludes.
