Double-Walled Tank

Definition

A tank constructed with two walls, designed for leak protection and to increase strength and stability.

Purpose

Double-walled tanks provide an added layer of security against leaks and environmental contamination, often used for storing hazardous or sensitive materials. The design enhances the tank’s structural integrity, making it suitable for both aboveground and underground installations.

Examples of Use

1. Fuel Storage: Used at gas stations to store gasoline and diesel, preventing leaks and spills.
2. Chemical Storage: Employed in industrial settings to safely store chemicals and hazardous materials.
3. Water Storage: Utilized for potable water storage, ensuring protection against contamination.

Related Terms

• Tank Liner: A protective layer inside a tank that prevents corrosion and leaks.
• Aboveground Storage Tank (AST): A tank placed above the ground, often with secondary containment measures.

Notes

• Regular inspections and maintenance are essential to ensure the integrity of double-walled tanks.
• They comply with stringent environmental regulations for storing hazardous materials.
