It has been announced by CAPA., the local governments water utility, that no water service will be available on the island from 8AM to approx. 8PM Tuesday ,while maintenance is done to the water supply system.
This should not impact visitors since most hotels have their own adequate water storage facilities. Also, most local residences have water storage tanks so it should not impact most residents. But might be good to know about this in the unlikely case you do encounter places without water on Tuesday.
