Residents across Durban may soon see relief after days of severe water disruptions.
Repairs to a critical control valve at Nagle Dam, which supplies the
Durban Heights Water Treatment Works, are nearing completion following
a major interruption to the city’s water infrastructure.
Emergency stabilisation measures, including water rationing, pumping restrictions,
and aqueduct supply reconfiguration, were implemented to prevent further strain on
the system while repair teams worked to restore operations.
Major Valve Failure Disrupts Durban Water Supply
The disruption began when a control valve at Nagle Dam seized in a closed position,
cutting off a large portion of raw water flowing to the Durban Heights Water Treatment Works.
This failure reduced the plant’s capacity by roughly 150 megalitres of water per day,
leaving several communities across Durban with extremely low pressure or no water at all.
The incident prompted urgent meetings between municipal leadership and water utility officials
to address the crisis and implement emergency supply measures.
Durban Water Supply Expected to Improve
According to Durban Mayor Cyril Xaba, the seized valve has now been successfully lifted,
allowing water to once again flow from Nagle Dam to the treatment facility.
This repair marks a critical step in restoring the water supply to Durban residents.
However, officials caution that it may take up to two weeks for the entire
water distribution system to stabilise.
During this period, reservoirs must refill, and pressure levels across the network
must gradually return to normal.
Water Rationing Plan Implemented
To protect remaining water reserves while the system recovers,
the eThekwini Municipality, together with uMngeni-uThukela Water, implemented a temporary Water Rationing Plan.
Under this arrangement:
- Some consumers will receive water only during the morning.
- Other areas will receive supplies in both the morning and afternoon.
- Restrictions will remain in place until the system fully stabilises.
These measures aim to balance supply across the network and prevent further outages.
Water Tanker Distribution Points Activated
To assist communities most affected by the shortages, several tanker filling
points have been activated across the city.
- Mobeni Depot
- Jeffels Road Depot
- Pinetown Depot
- Canelands
- Alverstone Nek Reservoir
A coordinated deployment schedule has been prepared to distribute water
to affected neighbourhoods as efficiently as possible.
Aqueduct Reconfiguration to Speed Up System Recovery
Engineers have also reconfigured the supply network so that both the
Northern and Southern aqueducts now draw water from Durban Heights Reservoir 2,
which has a smaller capacity.
By focusing on filling one reservoir instead of two, officials expect the
system to stabilise faster.
Durban Heights Reservoir 3, the larger reservoir, will remain temporarily isolated
until repairs to Aqueducts 3 and 4 are completed and raw water flows improve.
Residents Urged to Use Water Sparingly
Municipal leaders have urged Durban residents to conserve water wherever possible
during the recovery period.
Limiting unnecessary water use, such as garden irrigation or excessive household
consumption, will help speed up reservoir recovery and ensure a quicker return
to normal supply levels across the city.
While the valve repair marks a major breakthrough, responsible water use will
play an important role in helping Durban’s water system fully recover in the
coming weeks.
