UTILITY INSTALLATIONS
Ellingson Companies has the ability, expertise and experience needed to install a variety of different utilities from sewer and water to gas pipelines. With over 35 years experience in the design and construction industry you can be confident Ellingson Companies will provide you with a cost effective solution custom designed to fit the specific needs of your project.
Ellingson Companies can install sewer, water and other infrastructure utilities through conventional open cut and trenching methods. We have the equipment and safety measures needed to get your project done quickly, correctly and keep personnel safe.
Ellingson Companies has the ability to install up to 14” HDPE pipe, sewer force main, water main, gas lines through static plowing. We also have the ability to install Dual Wall HDPE tile for sanitary or storm sewer using static plowing. Compared to traditional open cut and trenching methods restoration and disturbance is minimized significantly.
Compared to conventional trenching and excavation methods, directional boring minimizes restoration and allows access to areas that were previously inaccessible. Ellingson Companies has utilized horizontal directional boring to install thousands of feet of gravity sewer mains, water mains, storm sewer, casing pipes, and gas pipeline, ranging in size from 1” to 42” under parking lots, driveways, roads, streams and lakes. We also have the capability of installing over 3,500’ of pipe in one shot. Ellingson Companies has the capability and experience needed to install materials on >1% grade for sanitary sewers, storm sewers, drainage crossings and other “gravity” needs.
When project constraints will not allow for Horizontal Directional Boring, Pipe Ramming is an effective trenchless method for installing steel casing. Pipe Ramming utilizes a pneumatic hammer that attaches to the new steel casing. The new pipe is set on grade and works its way through the ground as it is pushed into place by the pneumatic hammer. Ellingson Companies can install up to 36” steel casing utilizing the Pipe Ramming Process. Ellingson Companies can also utilize the same pneumatic hammer when pull force requirements or soil conditions require additional assistance to the Horizontal Directional Boring process.
Vacuum Excavation allows Ellingson Companies to expose existing utilities without “digging” for them. We know that utility strikes and damages are dangerous and costly, as well as inconvenient for our customers. We take every precaution to protect our customers and employees by utilizing vacuum excavation to help expose utilities and to clean out structures and pits that are full of dirt and other debris.
Perhaps most importantly, the Ellingson Companies HDD crew has gone through extensive training and certification on the use of bentonite, OQ certification for installing, handling, fusing and testing pipe used in gas installations and proper use of installation and excavation equipment.

In the fall of 2008 Ellingson Companies partnered with the City of Sioux Falls, SD for a gas line installation project. The project allows the City of Sioux Falls to sell methane gas, generated at a local landfill, to POET Energy helping fuel the boilers at POET’s Chancellor, SD ethanol plant.

Ribbon cutting was held on March, 27 2009 to officially open the facility. A variety of leaders from the City of Sioux Falls, POET Energy and the Environmental Protection Agency spoke about this exciting project and numerous local media outlets were on hand to cover the grand opening.
