Clearing, Chipping, & Grading


The pipeline right of way is cleared of vegetation by the clearing and grading crew. This crew is responsible for removing trees, boulders and debris from the construction right-of-way and preparing a level working surface for the heavy construction equipment that follows.

Stringing & Setup


Individual joints of pipe are strung along the right-of-way and arranged so they are accessible to construction personnel.

Steady and consistent trenching is the key to staying on schedule. For this reason, Pumpco has invested in 27 of the most technologically advanced trenchers available. Three Trencor 1760 Trenchers are capable of cutting 6 ft wide, 20 ft deep, and weigh 315,000 lbs. each. This level of commitment to the fundamentals of pipeline construction keep projects moving forward.

Mainline Welding


Once the stringing and bending are complete, the pipe sections are aligned, welded together, placed on temporary supports, and x-rayed. A coating crew then powder coats the pipe along the welded joints, inspects the coating, and lowers the pipe into the trench.

The ditch will be excavated in harmony with the lowering in crew using a series of sidebooms, which allow the operators to simultaneously lift and carefully lower the welded pipe sections into the trench. With the pipeline successfully laid in the trench, crews begin backfilling the trench.

The pipeline industry has shifted to an increased number of horizontal directional drills per project. To meet this demand, Pumpco has invested in a fleet of 22 horizontal directional drill rigs. A successful drill incorporates a variety of support equipment from cleaning units, water tanks, mud pumps, vacuum trucks, generators, drill strings, and many others. The Pumpco team leverages this equipment to make certain each project is on schedule and completed in a timely manner.

The Tie-in Crews will make the welds required to connect all of the previously installed sections of pipe together into one continuous pipeline. Tie-in Crews will begin to tie-in immediately after the pipe is lowered in.

In rocky conditions, Padding Machines are required to cover newly laid pipe, operating along the trench to ensure the pipe’s coating is protected before backfill. Pumpco owns 6 of these late model Superior and EZ Padding padding machines and 24 shaker buckets with crushers.
