Dam Levels Drop – Cape Town, once celebrated for overcoming the 2018 Day Zero scare, now finds itself on the edge of another water catastrophe. With dam levels plummeting to a dangerous 34.8% as of August 2025, the Western Cape government has sounded an emergency “Day Zero” warning. This development comes amid a broader national water crisis that is affecting multiple provinces, placing millions of South Africans at risk of water shortages, rationing, and severe restrictions. The Department of Water and Sanitation (DWS) issued an urgent appeal to all municipalities and households to reduce water consumption immediately. Despite consistent warnings since early winter, consumption has remained above sustainable levels, exacerbated by reduced rainfall, population growth, and under-maintained infrastructure. The current situation is particularly worrying for agriculture, hospitals, schools, and informal settlements that already suffer from limited access to clean water. Government departments have escalated their response plans, deploying emergency water trucks, accelerating borehole projects, and launching national awareness campaigns to urge residents to conserve every drop. The looming “Day Zero” scenario, where taps in households and businesses may be turned off entirely, is now no longer a distant threat but a very real possibility if consumption doesn’t decline.

What Is Day Zero and What Does It Mean for Cape Town?

- Triggered if dam levels fall below 13.5%
- Residents limited to 25 litres of water per day
