Greater Cape Town Water Fund (2020). Fact Sheet, September 2020.
The fund’s own summary: a target of about 54,300 hectares in seven mountain sub-catchments plus 5,000 hectares on the Atlantis Aquifer, 55 billion liters a year within six years and 100 billion by 2050, and a reported 4.8 billion liters a year from the first 10,000 hectares cleared. The wiki uses the delivered figure, about 480 cubic meters per hectare, as the clearing benchmark against which retention yields are compared.
