Cape Town residents are being urged to save water as declining dam levels and rising summer demand increase the possibility of restrictions returning.
Official City of Cape Town figures show the Western Cape Water Supply System at 73.8% capacity on 21 October, with storage continuing to decline as the rainy season comes to an end.
According to Cape {town} Etc, restrictions could be considered from around 1 December following discussions involving the City and the national Department of Water and Sanitation. No final decision has been made.
Dams Remain Below 80% Benchmark
The City says dams generally need to be at 80% or higher by the end of the rainy season to reduce the likelihood of restrictions across the shared water system.
Current levels remain well below that mark.
Theewaterskloof, the system’s largest dam, stood at 73.7% on 21 October. Voëlvlei was at 56.1%, while Wemmershoek stood at 81.5%.
The City’s 2026 Water Outlook does not indicate an immediate threat to supply, but officials say the risk of restrictions has increased compared with previous years if demand continues climbing and rainfall disappoints.
Cape Town Using More Water
Consumption is another concern heading into the hotter months.
The City reported usage of 895 million litres a day on 1 October, exceeding its target of 860 million litres. Officials estimate households need to reduce consumption by at least 10% during summer and into next winter.
About 70% of high-volume water consumption occurs in homes, making household savings an important part of the City’s response.
Restrictions Have Not Been Confirmed
Cape Town is not currently under water restrictions. The City confirms that restrictions have not been in effect since November 2020, although permanent water-saving regulations remain in place.
Officials are continuing to assess dam storage, demand and rainfall forecasts while awaiting further analysis of the wider water supply system.
Residents are being encouraged to fix leaks, reduce unnecessary water use and monitor household consumption before summer demand reaches its peak.
