MARIETTA — Cobb Parkway just north of Roswell Road was closed for more than five hours Saturday night while emergency crews from the Cobb County-Marietta Water Authority cleared the road after a water main break.
“We believe that there was a failure of a weld on the pipe,” said Glenn Page, the authority’s general manager. “So, we’re replacing that piece of pipe (Sunday).”
Page said the 36-inch water line is about 11 years old and broke sometime about 8:30 p.m. Saturday.
“I’m not sure where the call came from, but our plant noticed a pressure drop instantaneously,” he said.
By 9:15 p.m., crews were on site and attempting to close the valves, which were eventually turned off sometime around 10 p.m.
Officer David Baldwin with Marietta Police said they received multiple phone calls to 911 from individuals in the area who were reporting the break Saturday night.
“There were about 10,000 gallons of water per minute that was spewing out,” he said. “I think that was one of the biggest breaks we’ve ever had in the city.”
Marietta Police assisted with the closure of the road.
“We’re just glad it happened during the night hours and not during rush hour or anything like that,” Baldwin added.
Cobb Parkway was closed off to all traffic until about 1:45 a.m. Sunday, Page said.
“We brought in our safety barrels, cones and had all that in place,” Page continued. “We had full cooperation from fire and police to make sure when the water was flowing, the roads were closed.”
On Sunday, they closed the northbound, right turn lane between Roswell and Gresham roads for repairs and on Monday, Page expected the lane to be closed in the morning hours but not to have an effect on afternoon traffic.
In the meantime, Water Authority officials are still trying to determine how much water was lost, but they believe it was between 1 and 2 million gallons.
“That’s how much the water in our tanks dropped,” Page said. “We’ll determine exactly how much once we get everything cleaned up.”
He also said they don’t believe any residents’ water use was affected by the break.
“We never lost any pressure in the system, so we did not need a boil water notice,” Page said. “No one was ever out of water service to our knowledge.”
