Table Mountain Group Aquifers Explained

🌍 Understanding the Table Mountain Group Aquifer

The Table Mountain Group Aquifer (TMG) is a massive underground water system found deep within the sandstone mountains of the Western Cape — stretching beneath areas like Table Mountain, Stellenbosch, Hermanus, Worcester, and the Cederberg.

It’s made up of hard quartzitic sandstone and other layers of ancient rock that have cracks and fractures. Rainwater seeps into these cracks high up in the mountains, slowly filtering down until it gathers deep underground. This naturally filtered water becomes a clean and sustainable source of groundwater that can be accessed through a borehole.

In simple terms:
🌧️ Rainwater falls on the mountain → 💧 filters through the rock → 🪨 collects in cracks → 🚰 is pumped out via boreholes for use.
