It combines desktop research from databases like WARMS and the National Groundwater Archive with field-based 'groundtruthing' via hydrocensus surveys of private borehole owners. The project identifies the geological characteristics of the Table Mountain Group and Cape Flats aquifers and deploys Solinst Leveloggers to track water levels. The findings highlight a significant increase in private borehole drilling between 2015 and 2019 and note concerns among users regarding water quality and the sustainability of abstraction levels.","ai_generated":true,"unit":"wwfza-000153#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"A severe drought between 2015 and 2019 led to a sudden and unquantifiable increase in the number of boreholes and well points created, as well as the volume of groundwater abstracted within the City of Cape Town.","ai_generated":true,"unit":"wwfza-000153#insight-1","date_modified":"2026-10-23"},{"text":"The City of Cape Town relies on three primary aquifers for groundwater: the Table Mountain Group Aquifer, the Cape Flats Aquifer (stretching over 400 km2), and the Atlantis Aquifer (approximately 130 km2).","ai_generated":true,"unit":"wwfza-000153#insight-2","date_modified":"2026-10-23"},{"text":"In the Newlands study area, a hydrocensus of 105 visited properties found that 29% of residents were available to provide data.
