Lehighton River Crossing Water Main Replacement

The Lehighton Water Authority is requesting bids for installation of a water main replacement crossing the Lehigh River in Carbon County, Pennsylvania, with bids due August 26, 2026.

The project scope includes approximately 375 linear feet of 12-inch ductile iron pipe (DIP) water main installed via open excavation (including 65 linear feet crossing a levee) and approximately 775 linear feet of 20-inch high-density polyethylene (HDPE) water main installed via horizontal directional drilling. Work also encompasses water appurtenances, easement clearing, and abandonment of the existing 6-inch water main. The main extends from Lehigh Drive in Lehighton Borough across the Lehigh River to an existing connection near Bridge Street in Weissport Borough.

The contractor must comply with Pennsylvania Department of Environmental Protection regulations, including notification 15 to 30 days prior to construction commencement, and submit flood response and inadvertent return response plans for HDD operations. Excavation within the levee must follow OSHA requirements with no shoring permitted; excavated levee material must be stockpiled separately with Standard Proctor and compaction testing required for reuse. Erosion and sedimentation control measures are mandated, including rock construction entrances, filter sock barriers, trench plugs in stream crossings, and permanent vegetative stabilization with minimum 70 percent uniform perennial cover. The contractor must verify existing utility locations, maintain minimum 18-inch vertical separation between the water main and sanitary/storm sewer lines, notify One Call System at least three working days before excavation near utilities, and coordinate with Weissport Borough regarding inspections. Restoration must return conditions to pre-construction state, with as-built drawings required upon completion.
