The Department of Public Works has announced that a boil advisory has been issued for residents of Shasta County near Cragview.
The department said its due to "lost positive pressure."
It announced Saturday that on Friday a car hit a fire hydrant, causing a large leak.
The leak then drained the tank and a portion of the distribution system.
Repairs have since been made.
The pressure has since been restored, but it will be necessary to boil water until further notice.
The boiling requirement will remain until officials indicate that it is safe to drink.
Testing of the water could take as long as Jan. 5.
For more information regarding the advisory, call (530)-225-5571.
