Alliance Tank Service was founded in March of 2008. At our core are several highly motivated, energetic management team members with decades of Above Ground Storage Tank and Manufacturing Industry experience. From our humble beginnings to our strong well respected position within the industry, we have increased our revenue and customer base for ten consecutive years. ATS has grown to employ over seventy highly trained and experienced employees. Our staff includes health and safety, engineering, sales, marketing, operations, accounting, and our most valuable asset field and shop personnel.
The services offered by Alliance Tank Service have expanded. As of January 2018 ATS Group LLC (ATS) acquired Willbros Tank Services from Houston-based Willbros Group Inc. The expanded company will operate as ATS Group, LLC dba Alliance Tank Service. The acquisition allows ATS to offer expanded resources for steel tank construction and tank repair. Now ATS offers turn-key projects, building not only above ground storage tanks, but also offering consulting services, full engineering services, logistical services, piping, automation, building construction, concrete construction (buildings, truck, rail load outs, & tank foundations). Along with API 650 we now build API 12F and AWWA Storage Tanks.
ATS’s dedication to continuous improvement, diversification of products and services, implementation of new technologies both in business administration and field operations, and the desire to think outside of the box, have led us down a path of tremendous growth and success. ATS has great customers, employees, and suppliers that we have built long lasting relationships with and we are very excited about the future growth together.
