Hansen Drilling, founded in 1917 by Pete Hansen in Minnesota, began with hand-dug water wells before evolving to horse-driven rigs, cable tool rigs, and eventually rotary drilling equipment. In 1942, Pete moved the business to Vancouver, WA, where it expanded over 72 years from a 10-acre family property to a well-established operation. Specializing in water well drilling, well decommissioning, chlorinations, and more, Hansen Drilling became a trusted name in the industry. In 2018, the company joined ONEMESA but continues to deliver the same high-quality service customers rely on.
