Overview of the Drought Status
Cape Town is heavily dependent on surface water which is contained within 6 major dams (Wemmershoek, Voelvlei, Steenbras, Theewaterskloof and Berg River Dams).
Below is a breakdown of the state of the Western Cape dams as on 22 February 2021.
The City of Cape Town has released its Water Outlook for 2018, which is regularly updated as conditions change. For access to the interactive Dam Level Model, click here to download. For the Dam Level Model User Guide, click here. Although some dam levels are increasing with rainfall , the Western Cape is still at risk and therefore the South African Weather Service (SAWS) has recommended that drought measures continue for the foreseeable future. As such businesses need to plan for a new normal.
While many businesses are based in Cape Town, operations and supply chains may be located in other parts of the Western Cape. Thus it is critical for businesses to be aware of the water situation across the province.
Below you can find the latest Western Cape Municipal Drought Status issued by the Disaster Management Division of the Department of Local Government.
