Bottled water is being handed out to vulnerable Islanders who have been affected by a burst water main.
Hundreds of homes in the Arreton, Winford and Newchurch area are either without water or are experiencing low pressure.
A burst water man is to blame, according to Southern Water.
The issue was first reported at around 6pm last night (Friday).
Southern Water says it's been working through the night to locate the burst.
