Understanding the Critical Role of Underground Chemical Storage Tanks
The global market for underground chemical storage tanks
will grow at 5.8% CAGR through 2030 (Grand View Research), driven by tightening EPA regulations mandating secondary containment systems. Recent data reveals:
- 34% reduction in soil contamination incidents since 2018 through improved tank standards
- Single-wall fiberglass underground storage tanks show 99.97% structural integrity over 15-year deployments
- 0.002% annual leakage rate for double-contained systems vs. 1.7% for steel alternatives
Engineering Breakthroughs in Tank Fabrication
Modern underground fiberglass fuel storage tanks utilize vacuum-assisted resin transfer molding (VARTM) for:
- 72-hour continuous corrosion resistance testing (ASTM G152)
- 1.5x greater impact resistance vs. rotational molding
- 0.0005 in/hr hydrocarbon permeation rate (EPA 910-R-10-001)

FAQS on underground chemical storage tanks
Q: What are the key considerations when installing underground fiberglass fuel storage tanks?
A: Ensure compliance with local EPA/API regulations, verify soil conditions to prevent corrosion, and use proper backfill materials to avoid structural damage.
Q: How do single-wall fiberglass underground storage tanks differ from double-wall tanks?
A: Single-wall tanks lack a secondary containment layer, making them less leak-resistant, while double-wall tanks provide added protection through an outer shell and leak-detection systems.
Q: What are common risks associated with underground chemical storage tanks?
A: Risks include corrosion, leaks contaminating soil/water, and regulatory violations if tanks are not monitored or maintained regularly.
Q: How often should underground fiberglass fuel storage tanks be inspected?
A: Inspect annually for cracks/leaks, test integrity every 3-5 years, and follow manufacturer or regulatory guidelines for specific timelines.
Q: Can single-wall fiberglass tanks safely store corrosive chemicals?
A: Yes, but only if chemically resistant coatings are applied, leaks are monitored rigorously, and local regulations permit their use for hazardous substances.
