Pipeline Construction Update

Construction Methods

Energy Transfer continues to construct the Mariner East 2 and 2X pipelines in West Whiteland Township through their contractor, Michels. Construction is not expected to be completed until some time in 2021. 

Where you see large sound walls around pipeline construction sites, Energy Transfer is installing pipes deep underground via horizontal directional drilling (HDD). 

Where HDD does not work because of geology or other factors, Energy Transfer is opening trenches and installing the pipe where they can and boring underneath other areas, such as roads and streams, where they cannot.
