Where Does the Tap Water in Cape Town Come From?
Cape Town’s tap water primarily comes from rainwater collected by the Western Cape Water Supply System. The majority of the water, about 95%, comes from a regional, integrated surface water system managed by the national Department of Water and Sanitation. The city is also supplied by six major dams: Theewaterskloof, Voëlvlei, Berg River, Wemmershoek, and Steenbras Lower and Upper. Capetown has suffered from major droughts which also negatively impacted the water quality sources.

Is the Tap Water in Cape Town and the Western Cape Safe to Drink?
The tap water in Cape Town is safe to drink after treatment according to international standards. The city complies with strict water quality checks as prescribed by the national government’s Department of Water and Sanitation (DWS). The City of Cape Town’s Scientific Services Laboratory tests almost 6000 samples of water each year, ensuring the municipal water supply remains safe to drink. Download the 2024 water quality report.
However, this doesn't mean that the tap water that comes out of your tap is healthy to drink. Old pipes, chlorine by-products and unregulated substances such as PFAS and microplastics may negatively impact the water quality.
Furthermore the chlorine level is high compared to tap water in other parts of the world which means it may have a chemical taste and smell.
For tasty and purer water it's a good idea to use a water filter. See more information below.
What are the Common Issues with Tap Water in Cape Town?
While Cape Town’s tap water is generally safe to drink, it has faced challenges, particularly during periods of drought. During these times, residents have reported a change in water taste due to the presence of geosmin, a natural organic compound that grows in the water when new rainfalls break a dry spell. However, this does not pose a significant health risk.
More recently microplastics and PFAS have been reported to be found in tap water in Cape Town.
