Burlington tries to find cause of water main break

Story Topics

BURLINGTON, Iowa (AP) - Officials in Burlington are trying to figure out the cause of a water main break that’s led to a boil advisory in the area.

The break Sunday afternoon came from one of two water transmission lines leading from the Burlington Municipal Waterworks, the Burlington Hawk Eye reported (http://bit.ly/O5H0Pt ). It’s prompted a boil advisory in Burlington and West Burlington until at least Tuesday night.

Burlington Municipal Waterworks Director Alan Borden said the broken pipe, placed in the 1960s, should not have been compromised because of its age.

“It’s not an old pipe. They can last up to 100 years, depending how well they are maintained and what environment they are in,” he said. “It’s 30 inches in diameter, thick-walled concrete - thicker than steel. So it’s unusual that it broke. They usually last longer.”

He added that fixing the break won’t be easy, since the city doesn’t have all the necessary equipment for procedural work that’s required before the pipe can be excavated. The emergency repair will cost about $100,000.

Water was shut off from the broken line shortly after the leak was discovered. Still, an estimated 1.5 million to 2 million gallons went into Flint Creek. The line goes under the creek.

In the meantime, the city will use an extra water transmission line built parallel to the broken one. It was added in the 1970s as a safeguard.

The state Department of Natural Resources is monitoring the case. People are encouraged to boil their water or use bottled water until the advisory is lifted.
