Water Files: Desalination as a viable option for Cape Town's water problems

The construction of desalination plants has been put forward as one of the options to help the Western Cape province deal with the water crisis it currently faces.

The World Wildlife Fund (WWF) Wednesday Water File looks at desalination and its potential to put the rest of Cape Town out of its water shortage woes.

Senior Manager Freshwater Progamme for WWF, Christine Colvin unpacks some of the constraints around the idea that's been sold as the best option because Cape Town is surrounded by seawater.

Christine Colvin, Senior Manager Freshwater Programme at WWF SA

To get a big scale desalination plant is going to take several years to build and construct.
