Industry-Leading Fiberglass Storage Tanks
The future is here
Currently, we are the only manufacturer of underground fiberglass fuel tanks in the U.S. in compliance with the Third Edition of UL 1316. In addition, no other fiberglass tank company provides UL 2447-approved sumps which are built to a higher standard. In 2021, to meet our continued growth and introduction to the C-Store Industry, we acquired our newest manufacturing plant in Marion, SC and rebranded to Nationwide Tanks. Our vision is to provide the best products and services centered around the needs of the underground fuel and water market. Being the best means providing an outstanding engineered design, comprehensive quality control program, exceptional customer service, and delivering our products on schedule.

Standard Features



Potable Water Storage
Designed with corrosion-resistant materials of construction as the primary ingredient, our underground fiberglass water tanks provide an expansive range of benefits. Our premium resin and fiberglass, combined with our industry-leading, helically wound structure, provide the perfect combination for lasting product storage of critical fluids maintained underground and are the ideal blend for any water or wastewater application.

Petroleum Fuel Tanks
There is no doubt about it – fiberglass outperforms steel tanks, which are vulnerable to corrosive fuels and soil environments. Unlike a steel tank’s UL 58 listing that does not require ethanol compatibility testing, our UL 1316 approved fuel tanks are compatible with highly corrosive fuels such as all ethanol blends, DEF, Bio-Diesel, and ULSD. Nationwide Tanks provides a corrosion-free solution that holds up to the ever-changing fuel qualities, backed by a 30-year limited warranty.

Fire Suppression Tanks
The versatility of fiberglass tanks makes them ideal for commercial fire protection applications. As concerns continue to grow about water shortages in many parts of the United States, municipalities and facility owners continue to search for ways to better manage their water resources.
