Samuel Ariaratnam is an expert in trenchless technology, which uses surface-monitored, underground excavation tools to replace and install utility lines for oil, natural gas, water, sewer, electrical, and telecommunications without disrupting neighborhoods, roadways, railways, riverbeds.

Ariaratnam has been appointed by United States Secretary of Transportation Pete Buttigieg to the Technical Pipeline Safety Standards Committee, also known as the Gas Pipeline Advisory Committee, or GPAC.
