Borehole Drilling in the Western Cape
Cape Granite, Table Mountain Sandstone, and river alluvium make the Western Cape one of South Africa's most productive borehole regions. Discover local experts who know your area's geology.
Western Cape Geology at a Glance
The Western Cape sits on three main geological formations, each with distinct drilling characteristics. Cape Granite (dominant around Cape Town, Constantia, and Stellenbosch) is a hard, fractured rock that requires percussion drilling but delivers consistent low-to-moderate yields. Table Mountain Sandstone forms the iconic mountain aquifers and is moderately productive. River valley alluvium — particularly in the Berg River (Paarl), Breede River (Worcester), and Hex River valleys — offers the region's best yields and shallowest depths.

Western Cape Water Context
Following the 2018 Day Zero crisis, borehole demand in the Western Cape has remained elevated. The City of Cape Town now provides a streamlined process for registering water use from boreholes. All boreholes must be registered with DWS under Schedule 1 of the National Water Act. Yield tests and water quality certificates are required before municipal greywater substitution is permitted.
