History

A&A Drilling has been serving the Pacific Northwest for more than 50 years, building a reputation for dependable flow control solutions and practical problem-solving. Our services include hot tapping, line stopping, valve inserting, and other specialized techniques that allow critical systems to remain in operation while work is performed.

The company was founded in 1972 by Warren E. Anderson, Sr., with a commitment to doing the job right and earning long-term trust through quality workmanship. That foundation still guides A&A Drilling today as a locally owned and operated family business.

Over the decades, A&A Drilling has worked across a wide range of industries, including chemical, commercial, fire protection, high-tech, industrial, medical, institutional, military, municipal, nuclear, petroleum, power generation, pulp and paper, refining, and water and wastewater treatment. Our experience across these sectors allows us to deliver pragmatic, proven solutions tailored to each project’s unique demands.

We are proud members of UA Local 290, the Association of General Contractors (AGC), the American Water Works Association (AWWA), and the Oregon Association of Water Utilities (OAWU), reinforcing our commitment to safety, craftsmanship, and industry standards.
