Double-walled Tank

A: A double wall tank is an aboveground storage tank with an inner tank that holds your product and an outer shell that provides secondary containment around the inner tank. This integrated containment eliminates the need for an external containment basin and helps prevent environmental spills.

A: Double wall tanks offer enhanced safety and compliance advantages:
Built-in secondary containment reduces risk of leaks/ spills.
Helps meet regulatory requirements without separate berms or trays.
Often required for sensitive applications or locations with strict codes.
Compared with single wall tanks, double wall designs give added peace of mind, especially where environmental protection or compliance is critical.

A: When choosing a double wall tank, consider:
Capacity requirement (gallons)
Orientation (horizontal or vertical)
Product being stored (fuel, chemical, etc.)
Site requirements and regulations
Space or footprint constraints

A: You can request a custom quote by submitting your specifications through Request for Quote form on their website or by contacting their sales team directly. Their experts can guide you through tank selection based on your needs.

A: A double wall tank has an inner tank inside an outer one. This creates a space between them. It's a key part of keeping spills contained.
If the inner tank leaks, the outer one catches the spill. This stops harmful leaks from reaching the ground or water.

A: Double wall tanks are safer and save space. They don't need big concrete dikes or remote areas like single-wall tanks do. This makes them more efficient and environmentally friendly.

A: Regulations like the EPA's SPCC rule are strict. They aim to prevent spills. Choosing double wall tanks can meet these rules without extra costs.

A: Leak detection in double wall tanks is a big plus. Sensors in the gap between the tanks can spot leaks early. This helps catch problems before they get worse.

A: The choice of material depends on what's stored. Steel is good for oils, while plastic or fiberglass is better for corrosive chemicals. The right material helps the tank last longer.

A: Yes, proper installation and maintenance are key. Tanks need to be levelled and backfilled correctly. Regular checks on sensors and the tank's condition are also important. This keeps the tank safe and compliant.

A: While double wall tanks cost more upfront, they save money in the long run. They avoid the need for extra containment structures and prevent costly spills. This investment protects the environment and saves money on fines.
