Residents in a six-block area of University Park were without natural gas for much of Sunday, said a spokesman for Atmos Energy.

Except for a few customers who couldn't be reached, such as people out of town, all have had their gas service restored, said Ray Granado of Atmos.

Checking homes and re-lighting pilot lights is "a house-by-house process, so it took a while,” he said.

Excessive moisture in gas lines was believed to have caused the outage.

The area affected was between Preston Road and Hillcrest Avenue, just south of Northwest Highway.
