Crews remain busy with site activities eight months into our construction schedule, with approximately 90 percent of the pipe stringing and welding for the construction portion of the project complete.

Through May, pipeline construction personnel reported they continued to make safe, steady and environmentally responsible progress, working installation and maintenance of erosion control devices, pipe installation, backfilling, welding, trenching, fabrication and more. Many contractors are preparing to bring in materials and equipment to begin restoration. The company also continues with activities related to two horizontal directional drills (HDD) for specialized stream crossing across the project area, with the majority of HDD activities completed.


Asked and Answered:

What is Hydrostatic testing?

Williams hydrostatically tests all pipelines prior to placing them in service. Hydrostatic testing involves filling the pipeline with water and pressuring the line to 1.5 times the maximum allowable operating pressure. This testing allows operators to discover and repair any flaws that may have occurred during transportation or construction.

Initial inspection and hydrostatic testing allow Williams to validate the integrity of the pipeline before it goes into service and ensure the safe and reliable operation of the line once it is placed into service.

Welding is essential to creating a strong, functional pipeline. This skill leads to solid careers, and Williams is making sure student welders get the experience and education they need. A $17,500 Atlantic Sunrise Community Grant went to Thaddeus Stevens College of Technology for a welding technology program and scholarship, now in its second year. Students are trained in a variety of welding processes, including aluminum.



The grant money was used to purchase three welding guns. Welding instructor Leroy Begay said this equipment makes it possible for him to train students and puts them at an advantage when they are looking for jobs.

“It will put them above anybody else in this state,” Begay said. “We want to get them highly trained and get them a job anywhere in the industry.”

Williams recently announced $264,300 in community grants for 41 organizations, including first responders, schools and townships, across Pennsylvania. Since 2015, Williams has given out more than $2.2 million in grants to 309 organizations across the Atlantic Sunrise project area.



Community Engagement

Williams was pleased to be the lead sponsor at the recent Pennsylvania Parks and Forests Foundation (PPFF) annual awards banquet. PPFF is a nonprofit organization that works for the betterment and promotion of Pennsylvania’s state parks and forest system.
