A massive water main break has sent a geyser of water shooting into the sky in northwest suburban Norwood Park Township.

CBS Skywatch was over the scene in a residential area at the intersection of Bryn Mawr and Courtland avenues.

The Norwood Park Protection District said an engineering firm was drilling for soil in the area when it hit the water main and caused the eruption.

The main feeds parts of DuPage County, the fire protection district said.

The Chicago Department of Water Management, which serves the unincorporated area, said its crews rushed to scene to shut down the gushing 48-inch water main early Monday evening.

Neighbors stopped by to see the spectacle as crews worked to get it under control.

"I could see the street was flooded, I noticed the water — and when I saw this, it was like the Bellagio from Las Vegas here," said Anthony Marchetti. "I said, oh, this isn't good."

Crews successfully shut down the valves, and said they will begin repairs as soon as the break is evaluated. They said no customers lost water service.

A water main break will typically call for a boil order for homes in the immediate area, but no such order has been announced.  

Unincorporated Norwood Park Township is a residential area surrounded on all sides by the city of Chicago. The enclave uses Chicago street names for its east-west streets and Park Ridge street names for its north-south streets. 

The unincorporated enclave is most infamously known as the home of serial killer John Wayne Gacy, who lived — and murdered dozens of boys and young men — in a house at 8213 W. Summerdale Ave.
