A plant room bund is a critical component in the design of industrial and commercial buildings where mechanical and electrical services are housed. These rooms often contain fuel tanks, oil containers, chemicals, or equipment that can leak harmful substances. The bund serves as a containment system that prevents hazardous spills from escaping into the environment, thereby ensuring environmental protection, regulatory compliance, and workplace safety.

In this guide, we will explore everything you need to know about plant room bunds, including their purpose, design standards, materials, legal requirements, and maintenance.

What is a Plant Room Bund?

A plant room bund is a secondary containment system designed to capture and contain leaks, spills, or drainage from tanks or equipment within plant rooms. It is typically a raised structure or enclosure made of concrete, steel, or masonry, surrounding equipment such as diesel generators, fuel tanks, and boilers.

The primary purpose of a bund is to prevent environmental contamination, particularly in the event of a major equipment failure or fluid leakage. By containing spills within the bunded area, facility managers can avoid potential breaches of environmental legislation and mitigate health and safety risks.

Why Are Plant Room Bunds Necessary?

There are several important reasons for installing a plant room bund in a commercial or industrial setting:

• Environmental risk management: Containing harmful substances like fuel or chemicals protects nearby soil and water systems. 
• Fire hazard prevention: Many fluids used in plant rooms are flammable liquids, and containment minimizes fire risk. 
• Legal compliance: Building and environmental codes often mandate bunding in specific scenarios, especially where hazardous material storage is involved. 
• Asset protection: Preventing damage from leaks safeguards expensive infrastructure and equipment. 

Design and Construction Standards

To ensure effectiveness, plant room bunds must be designed and constructed in line with established industry standards. Key elements include:

• Capacity: Bunds should typically hold at least 110% of the largest tank’s volume, or 25% of the combined volume of multiple tanks. 
• Impermeability: The bund must be made of materials resistant to the stored liquid, often sealed with a chemical-resistant coating. 
• Freeboard allowance: Extra capacity should be considered for rainwater ingress or potential foam/firefighting discharge. 
• Accessibility and maintenance: Bunds should allow for easy inspection, leak detection, and cleaning. 

Proper drainage management within the bund is also crucial. Any drainage system must be fitted with valves or isolation mechanisms to prevent the escape of harmful substances.

Maintenance and Inspection of Plant Room Bunds

Over time, wear and tear can compromise a bund’s effectiveness. Regular inspection and maintenance are vital to ensure the bund continues to function properly. Key maintenance tasks include:

• Visual inspection for cracks or sealant degradation 
• Clearing debris and ensuring drainage outlets are not blocked 
• Testing impermeability of surfaces 
• Checking for signs of leakage or corrosion 

It’s also important to maintain a record of inspections, especially for compliance audits or insurance purposes.

Compliance with Legal and Environmental Standards

Installing a plant room bund isn’t just best practice—it’s often required by law. Regulations such as the Environmental Protection Act, Control of Pollution Regulations, and Building Services compliance standards may mandate bunding depending on the location, industry, and stored materials.

Failure to comply can result in fines, legal action, or environmental damage that could tarnish a company’s reputation. Consulting with environmental engineers or compliance consultants can ensure that your bund design and operation meet current legislation.

Conclusion

A well-designed and maintained plant room bund plays a crucial role in ensuring environmental protection, workplace safety, and legal compliance. From containing accidental spills to managing routine drainage, bunds are essential in any plant room that stores hazardous liquids or fuel-based systems.

By understanding the fundamentals of bund construction, adhering to proper inspection routines, and staying compliant with legal standards, businesses can avoid costly environmental damage and maintain operational efficiency. Investing in the right containment solution is not only a smart safety measure but also a long-term financial safeguard.

FAQs

1. What is the minimum capacity a plant room bund should have?
   A bund should hold at least 110% of the largest tank’s capacity or 25% of the total volume if multiple containers are used.
2. Can rainwater affect the efficiency of a bund?
   Yes. Bunds should be designed with rainwater ingress in mind and include proper drainage solutions with controlled valves.
3. Are bunds mandatory for all plant rooms?
   Not all plant rooms require bunds, but if hazardous substances are stored, most regulations will mandate bunding for safety and compliance.
4. How often should a plant room bund be inspected?
   It’s recommended to inspect bunds quarterly and after any incident involving spills, leaks, or major weather events.
5. What materials are commonly used to construct bunds?
   Bunds are usually made from concrete, masonry, or steel, often lined with chemical-resistant membranes for added protection.
