Work is underway Thursday morning to repair a second water main break from Wednesday.

The most recent break happened in the afternoon and is affecting residents on the 600 block of 13th Street in Humboldt.

That was coupled with a larger break that occurred on Wednesday morning. That break, which had users on 10th Street without water, has since been repaired.

If you were issued a yellow door hanger, that means you are in the zone of a drinking water advisory. The city will then place a green door hanger when levels are tested and water is once again safe to consume.

In the meantime, the city is advising those affected residents that they can use a clean water supply at the Uniplex if needed.
