Western Cape dam levels fall below 50% – how to avoid another Day Zero

As dam levels in the Western Cape drop below the 50% mark, residents are being urged to step up water-saving efforts. While there is no immediate crisis, it is worth taking action now to help avoid a repeat of the dreaded “Day Zero” scenario.

According to the Department of Water and Sanitation, combined dam levels in the province have dipped to just under half capacity following weeks of below-normal rainfall.

According to the reading for March 25 2026, major dams are sitting at just 48.3% of total storage capacity. The largest reservoir, Theewaterskloof Dam, is at 47.0%, while Berg River Dam is slightly lower at 43.7%.

The Steenbras system shows variation, with Upper Steenbras at a healthier 58.8% but Lower Steenbras lagging at 41.5%.

Meanwhile, Voëlvlei and Wemmershoek dams are just above the halfway mark at 53.3% and 53.5% respectively.

While authorities say supply remains stable for now, the situation is being closely monitored, with further assessments expected in the coming weeks.

For households, this means now is the time to ease pressure on the system through simple, everyday changes.

Cutting down daily water use

One of the most effective ways to save water is by reducing consumption during routine activities. Keeping showers under five minutes, turning off taps while brushing teeth, and only running dishwashers or washing machines with full loads can collectively reduce household usage.

Fixing leaks is also critical. Even a slow drip can waste litres of water over time, adding unnecessary strain to already declining dam levels.

Reusing water where possible

Greywater reuse remains a practical option for many households. Water collected from rinsing vegetables or from washing machines can be reused for flushing toilets or watering gardens.

Residents are also encouraged to water plants during cooler parts of the day, such as early morning or evening, to minimise evaporation.

Outdoor water use under scrutiny

Outdoor consumption, particularly garden irrigation and car washing, usually accounts for a large portion of household water use. Limit these activities or switching to more efficient methods, such as using a bucket instead of a hose.
