Safe storage of chemicals, acids, solvents, and industrial liquids requires more than a primary storage tank. Even a small leak, overflow, or accidental discharge can create serious handling and environmental challenges. A Bund Containment Tank provides an additional layer of protection by collecting leaked or spilled liquid around the primary storage tank.

Designed for secondary containment applications, bund tanks help reduce the risk of uncontrolled chemical spills and make liquid storage areas easier to manage. They are commonly used around chemical storage tanks, process tanks, dosing systems, and other industrial liquid-handling equipment. Petron Thermoplast offers industrial plastic tank and containment solutions for chemical processing, water treatment, manufacturing, and other demanding applications.

What Is a Bund Containment Tank?

A Bund Containment Tank, also called a secondary containment tank or bunded containment system, is a protective structure designed to collect liquid released from a primary tank.

The primary tank stores the chemical or liquid, while the bund surrounds or sits beneath the tank. If leakage or overflow occurs, the bund provides a controlled area for collecting the released material.

This arrangement can help prevent spilled liquids from spreading across floors, entering drainage systems, or reaching surrounding equipment.

A bund containment system can be designed according to the dimensions of the primary tank, required containment volume, chemical compatibility, available installation space, and project requirements.

Why Is Secondary Containment Important?

Industrial facilities frequently store liquids that can be corrosive, hazardous, or difficult to clean. A damaged tank, loose connection, overflowing vessel, or accidental hose failure can release liquid into the surrounding area.

Without secondary containment, the spill can spread quickly.

A properly designed bund can provide:

• Controlled collection of leaked liquids
• Protection for surrounding areas
• Reduced risk of uncontrolled chemical spreading
• Easier spill inspection and recovery
• Additional protection for floors and equipment
• Better organization of chemical storage areas
• Improved housekeeping around storage tanks

Key Features of Bund Containment Tanks

The design of a bund containment tank depends on its intended application and construction material. Industrial systems can include several useful features.

Chemical-Resistant Construction

Plastic containment systems can be manufactured from materials selected for resistance to specific chemicals. Depending on the application, materials such as PP, HDPE, PVC, or other compatible thermoplastics may be considered.

Chemical compatibility should always be checked against the actual liquid, concentration, temperature, and exposure conditions.

Strong Structural Design

A bund must withstand the weight and forces associated with the stored tank and contained liquid. Reinforced walls, support structures, ribs, bases, or fabricated sections can be incorporated according to the design.

Leak Collection

The containment area provides a defined space where leaked material can accumulate rather than spreading across the surrounding floor.

Custom Dimensions

Industrial storage installations often have different tank sizes and site layouts. Bund containment systems can therefore be designed according to specific length, width, height, and tank dimensions.

Easy Inspection

A visible containment area can make it easier for operators to identify leakage, accumulated liquid, or other problems around the primary tank.

Applications of Bund Containment Tanks

Bund containment systems can be used in many industries where liquid storage and spill control are important.

Chemical Storage

Chemical manufacturing facilities may use bunded areas around storage tanks to contain accidental leaks and spills.

Acid Storage

Storage systems for compatible acids can be installed within suitable secondary containment arrangements. The bund material must be selected according to the particular acid and operating conditions.

Water Treatment

Water treatment facilities often use chemicals for pH adjustment, disinfection, coagulation, and other processes. Bund containment can provide additional protection around chemical storage areas.

Effluent Treatment Plants

ETP facilities handle different process chemicals and wastewater streams. Secondary containment can help manage accidental liquid releases around chemical storage and dosing systems.

Pharmaceutical Industries

Pharmaceutical manufacturing facilities may require controlled chemical storage and handling arrangements. Bunded containment can be incorporated into suitable storage areas.

Metal Finishing and Electroplating

Chemical solutions used for surface treatment, pickling, and electroplating require careful handling. A suitable containment system can help control accidental spills around storage equipment.

Industrial Manufacturing

Factories using process chemicals, cleaning solutions, oils, or other industrial liquids can use secondary containment systems as part of their spill-management setup.

How to Select the Right Bund Containment Tank?

Several factors should be considered before purchasing a bund containment system.

1. Primary Tank Dimensions

Measure the length, width, diameter, and overall height of the primary storage tank and consider the available installation space.

2. Required Containment Capacity

The containment capacity should be determined according to the applicable project requirements, regulations, risk assessment, and engineering design.

3. Chemical Compatibility

Identify the exact chemical, concentration, temperature, and expected exposure duration before selecting the construction material.

4. Operating Environment

Indoor and outdoor installations may have different requirements related to weather, UV exposure, temperature, drainage, and structural support.

5. Tank Weight

The bund structure must be designed to safely support the primary tank and its contents where the tank sits directly within or above the containment system.

6. Access and Maintenance

Allow sufficient space for inspection, cleaning, transfer connections, valves, pumps, and routine maintenance.
