Highly congested urban utility corridors present some of the most difficult conditions for construction of new underground pipelines, especially when subsurface conditions are also very challenging. The difficulties presented in constructing a new sewer pipeline approximately 2,287 m (7,500 ft) long and 915 mm (36 in) in diameter through a utility corridor in the busiest part of downtown Honolulu were successfully resolved by specifying microtunneling methods for construction of the pipeline.
