Quarterly groundwater monitoring of the Cape Flats Aquifer (CFA) is undertaken by Umvoto geologists and hydrogeologists to build up a baseline prior to any large-scale abstraction and managed aquifer recharge (MAR).

Wellfields are spread across the CFA targeting the thickest portion of the aquifer within the paleochannel (old river channel). Some wellfields are located in areas with high crime rates which result in an ongoing battle of protecting the boreholes from vandalism and related contamination of the aquifer.
