Where does water come from?

Water evaporates from the surface of oceans into the atmosphere, forms clouds, falls onto the land as rain, travels through wetlands, rivers, lakes and underground, before returning to the ocean. The water you drink from a tap comes from lakes, rivers or ground water such as boreholes or wells.

More than half of the water we drink in the Western Cape comes from mountain catchment areas – these are areas of land that are “natural sponges”, which catch water when it rains and feed it to rivers.

These mountain catchment areas are threatened by fires and invasive alien vegetation – plants from other countries that do not naturally grow in South Africa.
