People in south suburban Robbins are being told to boil their water after a construction crew broke a water main.
Thousands of people were without water for much of the day Thursday.
The construction workers, who were putting in light poles, say their map did not show a water main was underneath them.
The village gave out jugs of water to anyone who came to pick them up.
The water was restored late Thursday night, but now a boil order is in effect through tonight as a precaution.
