Water started bubbling up from the street around 9 p.m. Tuesday night and then started flowing, according to a resident on the block near 48th and Paulina.
The water department arrived at midnight. According to the department, the snow is making it more difficult to handle the situation. The water main was capped and water was shut off from Paulina to Wood Street on 48th Street, the department added.
The cleanup and repair process is still underway while crews work in difficult conditions.
The cause may have been weather-related, but it is not confirmed. It is also unclear how many people in the neighborhood have been impacted by the water shutdown.
