1. Chemical Compatibility & Material Integrity
- Select corrosion‑resistant materials – specialized metals or polymers that won't pit or degrade with harsh chemicals.
- Prevents gradual internal deterioration of the primary structural shell.
- Essential for long‑term leak prevention.
2. Robust External Secondary Containment
- Concrete bund, earthen berm, or containment basin – vital safety net for primary tank failure.
- Captures and isolates escaping liquid from soil and groundwater.
- Critical environmental protection measure.
3. Rigorous Internal Inspections
- Regular internal inspections – check for corrosion, weld degradation, or sediment buildup.
- Use ultrasonic thickness gauging for non‑destructive wall integrity measurement.
- Detects hidden weaknesses without emptying the tank.
4. Protective Linings & Coatings
- Epoxy or polymer coatings – create seamless impermeable barrier against corrosive liquids.
- Shields base material from direct chemical contact.
- Regular maintenance extends tank lifespan and reduces leak risk.
