As long as the water bottlers aren’t price gouging, they are providing an emergency supply of water to a region that needs it.
As long as it's emergency... then again, some temporary policies may become permanent, but let's see
Edit:
I say this, because, if you look into the article, this sort of policy was de facto in Uruguay and Mexico
And it seems not only are they circumstantially restricted to bottled water, but a lot of the water seems to be directed to industries, rather than direct consumers
Here's the source of saying that in GMA news, a Filipino news site and channel:

She also "theoretically" threatened to throw president Bongbong's father's corpse into the sea
Why is she doing stuff like this, you ask?
Cuz Bongbong's making an China-hawk policy, regarding the West Philippine Sea claims
