The report describes the creation of a groundwater monitoring network in Constantia and Bergvliet, Western Cape, commissioned by WWF South Africa. Following a significant increase in borehole drilling during the 2015-2019 drought, GEOSS South Africa conducted a desktop study and hydrocensus of 309 properties. The project resulted in the installation of five Solinst Leveloggers in private boreholes, with data fed into a public Groundwater Dashboard for the Table Mountain Water Source Area. Findings indicate that most boreholes target the Springfontyn and Peninsula Formations, with water levels ranging from 7 to 16 mbgl and quality classified as "good" to "marginal".

The document describes the selection of four new groundwater monitoring areas—Brackenfell, Constantia/Bergvliet, Noordhoek, and Scarborough/Kommetjie—to support the City of Cape Town's water diversification efforts. Selection was based on borehole density, drilling activity during the 'Day Zero' period, equipment accessibility, and potential points of concern. These sites supplement existing monitoring in Newlands and Epping Industria to manage risks associated with unregulated groundwater abstraction under a changing climate.
