It happened near 1070 West Walden Meadows Drive in Murray.
River Ricord and Jonah Large, both ten years say they were just feet away from the blast when it happened.
“We ducked our heads on the ground and rocks just flew at us,” said Large. “Terrifying, what just happened right now? What should I do?”
“I thought it was the apocalypse,” said Ricord.
They say rock and cement rained down on top of them.
“If I didn't put my hands on my head I would have gotten hit on my head by a rock,” said Large.
Another eye witness who took pictures of the water main break is thankful he was more at a distance.
“I started taking pictures and videos and it was small and it kept getting bigger and bigger as it went on,” said Johnathan Richards.
Murray city crews were out all afternoon and evening cleaning up the mess and repairing the break which the city says was caused by typical deterioration.
The city says about 10-12 homes were without water, but it was expected to be restored by Monday night.
Repairs on the water main will continue Tuesday.
As for the boys, they walked away without any major injuries, but with one heck of a story to tell.
