Most likely due to the reckless expansion of AI datacenters that is consuming all the water supply.
The same is also happening to the southwest part of Johor where some of my family lives. Of course these politicians are in denial, they are clearly exporting water to Singapore where many resource hungry datacenters are located, at much higher prices than what locals are paying.
It may be true in your country but here, this is happening for over past 20 years or even more.
Sometimes, I think that other countries are doing better & think of relocating but escaping isn't a correct solution.
