1. Secondary Containment Through Double‑Wall Design
- Double‑wall construction with primary inner tank and protective outer shell.
- Interstitial space acts as a secure buffer zone between walls.
- If inner tank leaks, diesel is safely captured within the gap.
- Prevents fuel from escaping into the surrounding soil.
2. Continuous Interstitial Leak Monitoring
- Advanced sensors installed in the interstitial space detect liquid, vapor, or pressure changes.
- Proactive monitoring instantly alerts operators to breaches.
- Early detection allows immediate maintenance before fuel reaches the environment.
- Prevents widespread soil contamination.
3. Corrosion‑Resistant Outer Shell Protection
- Underground environments are highly corrosive to traditional steel.
- Modern tanks use durable, non‑corrosive materials like FRP for the outer wall.
- Excellent resistance to chemical and electrochemical degradation.
- Ensures structural integrity for decades.
4. Comprehensive Site‑Wide Soil Barriers
- Dispenser area and tank sump lined with impermeable concrete or membrane isolation.
- Secondary site barriers contain spills during the refueling process.
- Prevents diesel from seeping into underlying soil or groundwater.
- Complete containment at the installation site.
