20+ U.S. states
Operating Locations
Today, Seneca operates its services across more than 20 U.S. states.
Originally focused on petroleum systems—tanks, pumps, fuel-site builds—the company expanded in the 1970s into fuel transport and by the 1980s opened its first branch in Iowa.
Over the decades it added divisions in environmental and remediation (1990s), waste solutions (2003), and general contracting (2015), crafting a broad service portfolio.
Today Seneca operates in 20+ U.S. states via multiple offices and remote service techs, delivering design-to-maintenance solutions for fueling, environmental cleanup, energy systems and more.
Typical projects range from fueling-site construction and automotive/marine fueling systems to groundwater remediation, industrial electrical builds and hydro-blasting waste removal.
It brings its own crews, equipment and parts distribution—truly a turnkey ‘complete solution’ spanning fuel systems, environmental work, energy infrastructure and automotive service.
Despite being rooted in petroleum, it offers unusual cross-division collaboration—like building remediation systems in a trailer, then installing monitoring controls through its electrical arm.
A standout fact: Seneca constructs custom groundwater remediation units in its Iowa facility, ships them nationwide in skids, containers or trailers, then handles startup and operations on-site.
