As Eskom ramps up to stage 6 loadshedding, it puts a strain on the City’s contingency plans, limiting its capacity to protect customers from loadshedding stages.
The City said that its service providers remain vigilant, monitoring potential impacts on infrastructure and public safety.

Traffic signal management
The City operates 1 641 traffic signals, with 1 087 equipped with Uninterruptible Power Supply (UPS) systems. Of these, 360 use lithium-ion batteries, offering extended operation during loadshedding at critical intersections.
However, the remaining UPS systems may fail under continuous high-stage loadshedding. Residents are reminded to treat non-functional signals as four-way stops and report prolonged outages to the Transport Information Centre (0800 65 64 63).
Sewer system challenges
Extended loadshedding risks sewer overflows. The City tackles this with a swift sewage spill protocol, coordinating various departments. Priority measures include prompt containment, repairs and, if necessary, temporary closures until the water quality is deemed safe.
Key sewer pump stations have permanent generators, enhancing sanitation resilience. Maintenance staff remain on high alert, with all stations equipped with telemetry for monitoring.
Electricity infrastructure
Cape Town’s electricity infrastructure, though robust, faces risks from prolonged loadshedding. This includes secondary tripping when power returns simultaneously in an area, causing further outages.
Residents are advised to switch off appliances ahead of loadshedding to minimise this risk.
Risks from illegal activities
Non-stop high-stage loadshedding increases the vulnerability of infrastructure to illegal connections and cable theft.
The City encourages reporting such activities, offering a R5 000 reward for information leading to arrests or the recovery of illegal goods.
Swimming pool operations
Electricity is vital for maintaining pool water quality. During loadshedding, pools might close unexpectedly if standards decline. Patrons within the facility can stay, avoiding water, without additional charges.
Extended shutdowns causing mechanical failures may lead to temporary pool closures.
Public safety and preparedness
Residents can report electrical infrastructure damage via the following channels:
- SMS 31220
- Email [email protected]
- Call the Public Emergency Centre at 021 480 7700
