A 40ft Raised Bunded Store is a fully enclosed, heavy-duty steel container with an integrated secondary containment sump (a “bund”) that is raised off the ground. This specialized design provides the ultimate safe and compliant storage solution for hazardous liquids, oils, fuels, or chemicals, preventing any spillage from reaching the ground.
What Makes It Different?
This is a highly engineered unit, not a standard shipping container.
1. The “Raised” Design
The entire container is mounted on a steel frame or legs, lifting the floor above ground level. This provides critical advantages:
-
Easy Leak Detection: You can visually inspect the entire bunded base from the outside for any signs of a spill.
-
Corrosion Prevention: Lifting the steel floor away from ground moisture and standing water drastically reduces rust.
-
Cleaner Access: The working area underneath is clear of debris.
2. The “Bunded” Sump
A liquid-tight sump is built into the base of the container. Its capacity is at least 110% of the largest drum or tank stored inside (as per regulations). This captures any leaks or spills from the primary storage vessels.
Think of it as a secure, elevated garage with a built-in safety bathtub.
Key Specifications & Safety Features
| Feature | Details & Purpose |
|---|---|
| External Dimensions | 40′ L x 8′ W (Height varies with raising frame) |
| Primary Structure | 40ft shipping container, modified. |
| Key Safety Feature | Integrated Bunded Sump (e.g., 2,500+ litre capacity). |
| Construction | Often includes a chemical-resistant liner (e.g., epoxy-coated steel) inside the bund. |
| Access | Standard container doors, often with ramped access for drum handling. |
| Compliance | Designed to meet EPA and COMAH regulations for secondary containment. |
Who Needs This? (Critical Applications)
This unit is for mandatory safety and environmental compliance.
-
Industrial Facilities: Storing large quantities of waste oil, solvents, or chemicals prior to disposal.
-
Fuel Depots & Transport Companies: Safe bulk storage for diesel, AdBlue, or other fuels.
-
Farming & Agriculture: Centralized, safe storage for agrochemicals, pesticides, or fuel.
-
Construction Sites: Compliant storage for fuels, lubricants, and chemicals on major projects.
-
Utilities & Manufacturing: Any site with a large volume of hazardous liquids requiring failsafe containment.
Top Benefits
-
Regulatory Compliance: Provides clear evidence of meeting environmental protection laws for liquid storage.
-
Spill Prevention & Environmental Protection: The bund contains 100% of potential spills, protecting soil and groundwater.
-
Safety & Risk Reduction: Minimizes fire risk and slip hazards by containing leaks.
-
Security: All hazardous materials are locked inside a robust steel enclosure.
-
Long-Term Value: Prevents huge potential fines and cleanup costs from a single spill event.
Critical Considerations Before Purchase
-
Not “Off-the-Shelf”: This is a custom fabrication. Work with a specialist manufacturer.
-
Exact Sump Capacity: You must calculate the required capacity based on what you will store. 110% of the largest vessel is the legal minimum.
-
Site Preparation & Access: Requires a solid, level base (e.g., concrete). The raised design may need a ramp for drum access.
-
Higher Cost: Significantly more expensive than a standard container due to engineering, modifications, and certification.
-
Professional Installation: Should be sited and often assembled by experts.
Essential Questions to Ask the Manufacturer
-
“What is the exact certified capacity of the bunded sump?”
-
“What inner liner material is used, and what chemicals is it resistant to?”
-
“Can you provide structural calculations or engineering certification for the raised frame?”
-
“What regulatory standards does the design meet (e.g., BS EN 14015)?”
-
“Does the price include delivery, installation, and site-specific risk assessment?”
Raised Bunded Store vs. Standard Storage
| Need | Raised Bunded Store | Standard Container |
|---|---|---|
| Storing Hazardous Liquids | Required. The only compliant choice. | Illegal & Dangerous. No spill protection. |
| Environmental Compliance | Yes. Designed for it. | No. High risk of violation. |
| Leak Detection | Easy. Visual inspection underneath. | Impossible until damage is done. |
| Cost | High (but offsets massive liability). | Low. |
Final Warning & Recommendation
Storing bulk hazardous liquids is a major environmental responsibility. A standard container is never an acceptable solution.
Consult with an environmental health & safety (EHS) advisor to define your exact legal requirements. Then, procure your Raised Bunded Store only from a reputable manufacturer with proven experience and certification capabilities. The integrity of this unit is your primary defense against catastrophic environmental damage and unlimited liability.
40ft Raised Bunded Store
A 40ft Raised Bunded Store is a safe steel box for hazardous liquids. It is lifted off the ground and has a built-in spill tray (“bund”). This stops any leaks from reaching the soil. It is the right choice for safe, legal storage of oils, fuels, and chemicals.
Key Features Explained
1. Raised Off the Ground
The whole container sits on a strong frame. This lift has big benefits:
-
See Leaks Easily: You can check under the container for spills.
-
Less Rust: The floor stays dry, away from wet ground.
-
Clean Space: The area underneath is easy to keep clear.
2. Built-In Spill Tray (Bund)
A strong, leak-proof tray is part of the floor. It holds 110% of the largest drum inside. If a drum leaks, the spill is safely caught in this tray.
Think of it as a secure, lifted shed with a built-in safety basin.
