Crews are working to repair a water line in Blair County.

The Altoona Water Authority is making the repair behind the Holy Rosary Church on North 4th Street in the Juniata section of the City.

About two dozen customers will be without water until the repair is made.  The water authority expect that to take a few hours.

After the repair is made customers will be under a boil water advisory until further notice.  Click here for a link to the advisory.
