What remains unanswered still is the cause of the water main's rupture.
"There was no indication that the section of pipe was being stressed," said Bouchart, noting the pipe is approximately 49 years into its 100-year lifespan.
"The feeder main operated well within its pressure limits."
He also said the city installed acoustic monitoring equipment in early 2024, and that technology provided no indication the water main was experiencing any issues.
Bouchart said it appears metal wires within the pipe suddenly "snapped," affecting its structural integrity, and resulting in water gushing out "as one big event."

Suddenly snapped is wierd for a cabal that is under essentially a constant load and pressure.
