The water outage is due to the repairs and maintenance to the reverse-osmosis water-purification plant in Karon, the PWA explained in its announcement.
The water supply from the plant will be shut-off 9am until 4:30pm.
People are urged to collect any water they may require during the period beforehand.
“We apologise for any inconvenience caused,” the PWA statement said.
