Northern Directional Drilling, Inc. is a directional boring contractor serving the San Francisco Bay area for the installation of pipelines and utilities. NDDI was started in June of 2008. Northern's primary purpose is to provide HDD services to the underground industry for the installation of pipeline and utilities.

Tommy Demus and Chad Morgensen have been in the underground utility and directional boring industry for 20 years each. Tommy Demus started in the natural gas pipeline on the east coast but moved back to the west coast in 1999 to work for a directional boring company working for various fiber optics companies during the internet boom in 1999. Chad Morgensen had worked for a directional boring company in the northwest and moved to California for the same company. Since then Chad and Tommy have worked for a couple of companies prior to starting Northern Directional Drilling, Inc in 2008.

Northern typically works for utility owners, government agencies, municipalities, and large general engineering contractors for the installation of pipelines and conduit by horizontal directional drilling. Projects are typically pipeline projects for water, recycled water, natural gas, sewer, electrical and communications. Projects are typically crossing of wetlands, waterways, highways and freeways, or other sensitive areas.

Northern owns 5 Ditch Witch (Ditch Witch is the manufacturer) with the largest being a Ditch Witch JT100 with 100,000 pounds of pullback. Northern only employs experienced and skilled workers with experience ranging from 5 years to 18 years and employment at Northern from 5 years to 10 years.
The owners of Northern Directional Drilling are directly involved in each project from estimating to design and planning to directional boring and installing the pipeline. Northern's employees use their experience to provide an HDD design that is not only beneficial for the drilling operation but also considers the general contractors and owners needs after the pipeline is installed. Northern owns some of the largest drilling equipment in the bay area for any HDD project. Northern has the correct drill rig for any situation including drilling in rock or installing large diameter pipeline.
