Following a significant increase in borehole drilling during the 2015-2019 drought, the project conducted desktop assessments and a hydrocensus of 111 properties to identify groundwater use patterns. The study found that most boreholes were drilled between 2016 and 2020, targeting the Tygerberg Formation. Four Solinst Leveloggers were deployed in private and public boreholes to track water levels, with data integrated into the Table Mountain Water Source Area Groundwater Dashboard.
