The AJC digs and gets some answers as to why a DeKalb County Water and Sewer crew accidentally cut an “incorrectly installed” gas line on Coventry Road yesterday.

The damage was caused by a county Water and Sewer crew that was repairing a damaged sewer main.

A remote television device spotted intrusion from tree roots. The workers were cutting into the sewer main to repair it when they damaged the gas line.

The gas line had been incorrectly installed, county spokeswoman Shelia Edwards said. She said it had been “bored” into the sewer main.

That can happen with all kinds of new lines, including cable and gas, Edwards said. “They don’t realize it until we have this kind of situation,” she said.
