Yes, indeed. That's how 95% of water is supplied in all of the islands. It is desalinated water drawn from the ocean. Those plants are very expensive. There are some private plants in Sal and Boavista that were installed by the big hotels to ensure 24x7 supply to their international tourist guests.
In addition, there is drip irrigation from desal plants (not potable), several massive dams for collecting rainwater and distributing by drip, as well as well-water (delivered in trucks), all for the agricultural regions of the country (Santiago, Fogo, Santo António and São Nicolau (which are the regions which supply food into the food supply chain).
In essence, they've been implementing various solutions for decades. The lowest priority would of course be for water uses which are not sustainable, like showers on the beach.
Hope this helps your understanding of the water infrastructure in CV.
Cheers,
