Project : Taunton River Gas Distribution Main Replacement

Liberty Utilities Massachusetts -- Fall River and Somerset, Massachusetts

CHA is providing engineering and permitting services to abandon, remove and replace two natural gas distribution mains along the bottom of the Taunton River between Fall River and Somerset, with one 12-inch steel pipe. Horizontal direction drilling (HDD) was selected for the installation of the new pipe to limit environmental impacts. The 1,900-foot HDD alignment also considered the surrounding community and included limited work space for construction to reduce impacts to nearby businesses and traffic.

Services provided by CHA:
  • Design
  • Permitting
  • Topographic, Geophysical and Hydrographic Surveys
  • Environmental Assessments (Wetlands and Habitat)
  • Diver Observation of Pipe Conditions
  • Geotechnical Investigation and Laboratory Testing
  • HDD Alignment and Route Assessment, Including Stress Analysis
