Kabul, a city of over six million people, could become the first modern city to run out of water in the next five years, a new report has warned.

Groundwater levels in the Afghan capital have dropped drastically due to over-extraction and the effects of climate change, according to a report published by nonprofit Mercy Corps.

Several years ago I heads that Capetown South Africa would be the first major city without water...

Cape Town apparently decided to use desalination.

https://resource.capetown.gov.za/documentcentre/Documents/Graphics%20and%20educational%20material/Desalination_Booklet_English.pdf

Permanent desalination is planned because seawater is available all the time, whether it rains or not, so it’s more reliable than any other water source. About 97% of water on Earth is in our oceans. We can make use of this huge resource through the process of desalination, which makes it drinkable and usable for us. Although desalination is the most expensive supply option and there are environmental issues that need to be well-managed (such as the salty ‘brine’ it produces as a waste product), it is an important part of the diversified water supply ‘mix’ going forward.

Says they start construction in 2026 and expect production starting in 2030.

Does desalination also get rid of microplastics and other chemicals like mercury?

[–] GreyEyedGhost@lemmy.ca 2 points 3 hours ago

Both distillation and reverse osmosis should get rid of microplastics. Reverse osmosis should get rid of mercury in any form, while it would depend on other chemical properties (evaporation rate, temperature source water is heated to, etc.) on whether distillation would remove chemicals like mercury.

Some further reading.

Thanks for the info. The link isnt loading for me, but I hope they are able to leverage renewables to power the desalination, as I've heard it is an energy-intensive process.
