Thompson Tank Inc.

Thompson Tank offers DOT inspections, vac tank repair services, and custom vac tank and trailer design and manufacturing for our worldwide clients. From simple beginnings to more than 80 years of excellent service, our family-owned, California-based company continues to help businesses succeed. We took root in the mid-1930s when C.S. `Tommy` Thompson coordinated with Jop Chancellor to design a vacuum pump in order to empty a shaker pit on Signal Hill. Tommy continued to build on that industry-changing idea to develop the first vacuum-loading portable cargo tank. He established the Thompson Tank & Manufacturing Company after returning from WWII in 1946. The company, which was renamed Thompson Tank Inc. in 1994, is now owned and operated by David B. Thompson, Tommy`s grandson.
