Why do you assume mainland tap water and tap water on a tiny island far out in the ocean have the same quality?
In spain mainland tap water is generally considered drinkable.
I’m sorry, re-reading my comment it comes across very harsh. I didn’t mean that.
The government certainly regulates the requirements for water to be considered drinkable. However it is probably not feasible to make all tap water on an island drinkable. Most of the water running through the tap is not consumed (like shower, laundry, flushing, etc.) so it might be smarter to make the water clean enough for those jobs and then advise to consume only bottled water.

I drank tap water all over mainland Spain without issue and my stomach is weak for this sort of thing.
Because the tap water is subject to the same legal framework, that’s why you assume it has the same quality standards.
