About Cape Town's Water Supply
Cape Town's water supply comes from six major dams in the Western Cape. After the 2017-2018 water crisis — when dam levels dropped below 20% and the city nearly reached 'Day Zero' — monitoring dam levels became critical for residents and visitors alike.
Did you know?
Theewaterskloof Dam holds over 50% of Cape Town's total water supply capacity at 479.3 million cubic metres. During the 2018 crisis, it dropped to just 10% capacity.
This water supply tracker provides current levels from the Department of Water and Sanitation's weekly reports, automatically updated every Monday.
