The project to repair a water main serving portions of the Dutch Hill section of Tamaqua is proving to be an extensive operation.
The 30-inch main is located in a steeply-sloped, wooded mountainside alongside a section of Elm Street commonly called Snake Hill.
According to workers on scene, the borough first had to cut down large trees and then build a temporary but substantial road to access the site with heavy equipment.
Work has been underway since the middle of July.
On Tuesday, the Tamaqua Area Water Authority issued a water boil advisory for parts of Dutch Hill.
The advisory will remain in place until the work is completed and tests have indicated that the water is safe to use.
