Cape Townâs first desalination plant – South Africa Mother City residents could be drinking seawater by as early as August of this year. Great news, seeing as the recent rains â as heavy as they were â barely made a dent in the dam levels of the resources supplying the city, pushing them up to just over 23%. Officials are hopeful that, as of August, Capetonians wonât be completely reliant on existing dams and reservoirs, what with an additional 500 million litres of desalinated water being pushed out per day.
