The City of Cape Town’s ambitious R5 billion desalination project, set to bolster the city’s water supply, has drawn both praise and scepticism, Cape {town} Etc reports.
The proposed plant in Paarden Eiland aims to produce up to 70 million litres of potable water per day, supporting Cape Town’s growing demand as part of the New Water Programme.
While the City assures the plant will follow the latest scientific research and environmental guidelines, some experts question the project’s viability, particularly regarding its environmental impact and the high cost of desalinated water. Critics argue that desalination, being one of the most expensive methods to provide drinking water, could strain the City’s resources.
Concerns have also been raised about the site’s proximity to a polluted harbour and contaminated rivers, which could affect the quality of water input and lead to further ecological harm.
Additionally, the disposal of concentrated brine from the desalination process could exacerbate marine pollution.
Despite these worries, proponents like Professor Anthony Turton emphasise that Cape Town must secure reliable water sources to ensure long-term sustainability, suggesting that desalination could play a crucial role in achieving this goal.
The City is currently conducting a feasibility study and has opened the floor for public comments until 3 March.
While the project promises a new source of water in an uncertain climate, the debate over its costs and potential environmental risks is far from settled.
