An option to trenchless construction

Trench boxes shore up excavation for sewer pipeline relocation across Saucon Creek in Bethlehem, Pa.

Excavator backfilling trench after pipeline placement.

The 48-inch steel carrier pipe was installed in two phases, each spanning half the creek at a time. A Portadam cofferdam temporarily redirected the flow of water, while the Monroeville, N.J., branch of Rain for Rent dewatered and maintained inflow infiltration. The process was repeated from the opposite side of the stream.
