Cape Town’s 2015–2018 drought crisis exposed the city’s vulnerability to extreme water scarcity. This episode explores whether desalination - specifically reverse osmosis - could be a viable solution to meet the city’s future drinking water needs. Based on literature review, stakeholder analysis, and a multi-criteria assessment, the feasibility of supplying 300 million litres per day through desalination is evaluated. Technical options, energy demands, environmental concerns, and the financial implications are discussed, ultimately concluding that while desalination could help diversify Cape Town’s water sources, it must be part of a broader, integrated strategy supported by robust energy infrastructure and inclusive governance.
