Humboldt city crews are working on a watermain break Wednesday afternoon.

The "large" rupture is affecting both the 700 and 800 blocks of 10th Street as well as St. Augustine Church and the Prairie Ridge apartment complex located at the corner of 10th Street and 8th Avenue.

Crews have isolated the break and are preparing to make repairs.

Affected residences will be notified with a yellow door hanger as a drinking water advisory will need to be issued.

There is no word on how long the repairs will take.
