PPL Electric Utilities of Allentown is conducting surveys and mapping its underground facilities in seven cities.
The project on the company's low tension networks is now in Allentown and will proceed in about two weeks to Bethlehem.
The program should run up to eight months and also include portions of Harrisburg, Lancaster, Wilkes-Barre, Scranton and Williamsport, said Rich Muza, manager, underground facilities and damage prevention, in a prepared statement.
Work will be done by electricians and surveyors for Aldridge Electrical Inc. The work began in Allentown in the vicinity of Front and Linden streets and will move from east to west across the center city district.
Crews will conduct inspections of the underground manholes and vaults that contain fiber optic cables, power lines, lines that feed local street lights, and other electrical equipment to identify any maintenance issues that need to be addressed.
Additionally, they will take panoramic photographs of the inside of the manholes or vaults and paint pink dots and other markings. The photos will be used to delineate the underground lines to allow survey crews to follow separately and gather information needed to develop detailed maps.
PPL Electric Utilities will use this data as it moves forward with projects to replace older equipment for improved system reliability and quality of service.
