Bund Containment Tank with Custom Size and Capacity

Chemical storage and handling require more than a primary storage tank. Industrial facilities also need a reliable secondary containment system to help manage accidental leaks, spills, and overflow. A Bund Containment Tank provides an additional layer of protection around a chemical storage or process tank.

With a custom size and capacity, a bund containment tank can be designed according to the dimensions of the primary tank, available installation space, chemical requirements, and site conditions. This makes it suitable for different industrial applications where standard containment systems may not provide the required fit.

Petron Thermoplast provides custom-fabricated thermoplastic containment solutions for chemical storage and industrial applications, with options based on tank dimensions, capacity, material, fittings, and project requirements.

What Is a Bund Containment Tank?

A Bund Containment Tank is a secondary containment structure designed to collect liquid that may escape from a primary storage tank, process tank, chemical container, or connected piping system. The primary tank stores the chemical or process liquid. The bund acts as a protective containment area around or beneath the primary tank.

Its main purpose is to help:

• Control accidental chemical spills
• Reduce the spread of leaked liquids
• Protect surrounding floors and equipment
• Support safer chemical handling
• Simplify spill management
• Reduce the risk of contamination around storage areas

Why Is Secondary Containment Important?

Even a properly designed storage tank can experience leakage because of damaged fittings, piping failures, accidental impact, overfilling, connection problems, or other unforeseen events.

Without secondary containment, a chemical spill can spread across the plant floor and potentially reach drains, equipment, soil, or other sensitive areas. A properly designed bund provides an additional barrier between the stored liquid and the surrounding environment.

For industrial chemical storage areas, secondary containment can therefore be an important part of the overall safety and spill-management strategy.

Custom Size and Capacity

Every industrial facility has different storage requirements. A standard bund may not fit a particular tank or installation area.

A custom Bund Containment Tank can be designed according to:

• Primary tank length
• Primary tank width
• Primary tank height
• Required containment capacity
• Available floor space
• Tank support arrangement
• Chemical type
• Number of tanks
• Piping connections
• Drain requirements
• Installation conditions

Materials Used for Bund Containment Tanks

Material selection is an important consideration when handling chemicals. Thermoplastic materials can offer good corrosion resistance for many chemical applications.

Common materials may include:

Material	Typical Characteristics
PP	Good chemical resistance and fabrication flexibility
PPH	Suitable for demanding chemical applications
HDPE	Good chemical and impact resistance
PVC	Suitable for many compatible chemical services
CPVC	Useful where higher temperature capability is required
PVDF	Excellent resistance for demanding chemical environments

How Does a Bund Containment System Work?

A typical arrangement consists of a primary storage tank positioned within or above a secondary containment area.

Under normal operating conditions, the primary tank holds the chemical. The bund remains available to collect liquid if a leak or spill occurs.

If the primary tank develops a leak, the released liquid is directed into the containment area rather than spreading across the surrounding plant floor.

Depending on the design, the containment system can include:

• Drain arrangements
• Sump areas
• Inspection access
• Removable covers
• Level indication
• Tank supports
• Custom nozzles
• Pump-out arrangements

Applications of Bund Containment Tanks

Bund containment systems are used in several industries where liquids need controlled storage and handling.

1. Chemical Storage

Chemical plants may use secondary containment around tanks storing acids, alkalis, solvents, and other compatible chemicals.

2. Acid Storage

Acid storage areas can benefit from secondary containment to help manage accidental leakage and prevent uncontrolled spread.

3. Water Treatment

Chemical dosing and treatment facilities often store chemicals in dedicated tanks. A bund can provide additional protection around these storage systems.

4. Electroplating and Metal Finishing

Plating plants may handle several aggressive chemicals. Bunded containment can be incorporated into chemical storage and process areas.

5. Pickling Operations

Pickling processes involve corrosive chemical solutions. Secondary containment can help protect the surrounding work area in case of leakage.

6. Manufacturing Plants

Industrial manufacturing facilities may use chemicals, oils, cleaning agents, and process fluids that require controlled containment.

7. Chemical Distribution and Storage Facilities

Bulk storage facilities can use containment systems around chemical tanks to support safer storage operations.

Key Features of a Custom Bund Containment Tank

A properly designed bund can include several application-specific features.

Custom Dimensions

The length, width, and height can be designed according to the primary tank and available installation space.

Chemical-Resistant Construction

The selected thermoplastic material can be chosen based on the chemical being contained.

Reinforced Construction

Large containment systems may require additional reinforcement to maintain structural stability.

Easy Inspection

The design can provide access for inspection and cleaning.

Drain or Sump Arrangement

A controlled drainage or sump system can help manage collected liquid, subject to the site’s operating and safety procedures.

Tank Support Integration

The bund can be designed around the support arrangement of the primary storage tank.

Custom Connections

Pipe, drain, overflow, and other connections can be incorporated where required.

Benefits of a Custom Bund Containment Tank

Choosing a custom solution can provide several practical advantages.

• Better use of available installation space
• Application-specific containment capacity
• Improved compatibility with the primary tank
• Reduced risk of uncontrolled liquid spread
• Chemical-resistant material options
• Easier integration with existing systems
• Flexible drain and piping arrangements
• Suitable for different tank configurations
• Simplified inspection and maintenance

Bund Containment Tank Capacity

Containment capacity is one of the most important design considerations.

The required capacity should not be selected simply by looking at the physical dimensions of the primary tank. Engineers may need to consider:

• Primary tank volume
• Number of tanks inside the bund
• Freeboard requirements
• Potential rainfall for outdoor installations
• Displacement from tank supports and equipment
• Applicable local regulations
• Chemical properties
• Emergency response procedures

Technical Factors to Consider Before Ordering

Before requesting a quotation, buyers should provide complete project information.

Requirement	Details
Primary Tank Size	Length, width, height
Tank Capacity	Total and working volume
Chemical	Chemical name and concentration
Temperature	Normal and maximum operating temperature
Bund Dimensions	Required length, width, and height
Installation	Indoor or outdoor
Tank Quantity	Number of tanks to be contained
Drainage	Drain or sump requirements
Connections	Required piping and fittings
Material	Preferred thermoplastic or application requirements

Providing these details helps the manufacturer understand the application and develop an appropriate design.

Custom Bund vs. Standard Bund

Standard containment systems can work well for common tank sizes. However, custom fabrication provides greater flexibility when the installation has special requirements.

Feature	Custom Bund Containment Tank	Standard Bund
Dimensions	Application-specific	Predetermined
Capacity	Customizable	Fixed
Tank compatibility	Designed around project requirements	Limited to standard sizes
Connections	Custom options	Standard options
Space utilization	Optimized	May require additional space
Project flexibility	High	Moderate
