A damaged control valve has disrupted the supply of raw water to the Durban Heights Water Treatment Works, resulting in a significant shortfall in water supply to eThekwini Municipality.
According to uMngeni-uThukela Water, the damage occurred during routine maintenance at Nagle Dam, which supplies raw water to the treatment plant.
The incident has prevented the facility from receiving its normal inflow of raw water, creating a supply deficit of about 150 megalitres per day — equivalent to 150 million litres — within the municipal water system.
Technical teams from uMngeni-uThukela Water are currently on site conducting a detailed assessment to determine the extent of the damage and the repairs required to restore normal operations.
The utility says the matter is being treated as a priority, with engineers working urgently to identify the most effective solution.
At this stage, officials have not confirmed how long the interruption will last. Further updates are expected once the assessment is completed and a repair plan is finalised.
uMngeni-uThukela Water has apologised for the inconvenience caused and assured residents and stakeholders that every effort is being made to resolve the issue as quickly and safely as possible.
The public will be informed of any significant developments as the situation progresses.
