Bunded pallets are purpose-built spill containment platforms that keep drums, small containers and IBCs raised above a bund (sump) so leaks and drips are captured before they reach floors, walkways, soil or drains. They are widely used across utilities, water and wastewater sites, engineering workshops, chemical storage areas and distribution yards where controlling liquids is essential for safety, housekeeping and environmental compliance.
Question: What problem do bunded pallets solve on real sites?
Solution: They provide a controlled, compliant way to store liquids so that minor leaks do not become major incidents. Day-to-day operations often include transferring, dispensing, sampling, and moving containers with forklifts. Those routine actions can cause small spills which, if uncontrolled, spread into pedestrian routes and drainage systems. Bunded pallets contain those spills at source, reducing slip hazards, clean-up time, and the risk of pollution events.
On water and wastewater facilities, for example, common liquids include treatment chemicals (such as coagulants and dosing reagents), oils, lubricants and cleaning fluids. Containment is particularly important where areas drain to surface water systems, interceptors, or treatment works where contamination may cause process disruption or environmental harm.
Question: What is a bunded pallet, and how does it work?
Solution: A bunded pallet combines a load-bearing top deck with an integrated sump below. Containers sit on the deck; any leak drains into the sump rather than onto the floor. Many designs include removable grates to make inspection and clean-out easier. Models are available to suit:
- Single drum storage and dispensing
- Two or four drum storage units for small chemical stores
- IBC bunded pallets designed for the footprint and weight of 1000L containers
- Low-profile bunds for manual handling areas
- Forkliftable bunded pallets for yard storage and logistics operations
Question: How do I choose the right bunded pallet for drums or IBCs?
Solution: Match the bunded pallet to your liquid type, storage volume, handling method and site conditions. In practice, selection usually comes down to the following checks:
- Container type and quantity: confirm whether you are storing 205L drums, smaller containers, or 1000L IBCs, and how many at once.
- Compatibility: ensure the pallet material is compatible with the liquids stored (for example, many aggressive chemicals require high chemical resistance).
- Load rating: confirm safe working load for full containers, including any dynamic loads if moved by forklift.
- Bund capacity: confirm the sump volume is suitable for your storage arrangement and internal standards.
- Handling and access: decide whether you need forklift pockets, a ramp, or a low step height for manual dispensing.
- Location: consider whether the unit will be indoors, outdoors, in a dosing kiosk, or in a yard exposed to rainfall.
If you are unsure, it is often safer to select a bunded pallet with higher capacity and better chemical resistance, then control rainfall ingress outdoors using covers or by relocating to sheltered storage.
Question: Do bunded pallets help with environmental compliance in the UK?
Solution: Yes. Bunded pallets support good practice for preventing pollution by keeping potential contaminants away from drainage. Many UK sites must demonstrate that they have taken all reasonable precautions to prevent releases to the environment and to manage foreseeable leaks from stored liquids. On utilities and industrial sites, bunded storage is also frequently required by internal environmental management systems, insurer expectations and permit conditions.

Question: What is the difference between bunded pallets, drip trays, and full bunded areas?
Solution: These controls do different jobs, and often work best together:
- Bunded pallets: storage containment for drums and IBCs with an integrated sump.
- Drip trays: localised capture under small leaks (often under valves, pumps, or during decanting). Useful where a full pallet is not needed.
- Bunded areas (bunding): larger fixed containment for multiple containers, tanks or plant. Better for high volumes, mixed storage and higher consequence areas.
Where chemicals are dispensed, consider adding drain protection at nearby gullies and keeping spill kits close to the point of use. This layered approach helps you respond quickly if a spill escapes primary containment.
Question: How should bunded pallets be used on site day to day?
Solution: Treat bunded pallets as a working control, not just a storage accessory. Practical steps that improve performance include:
- Positioning: place pallets away from vehicle routes where possible, and keep them clear of drains and doorways.
- Dispensing controls: use tap lock devices, closed transfer systems, and drip trays under taps and connectors.
- Inspection: check containers, valves and bund sumps routinely. Look for weeping fittings, damaged drums, and chemical attack on the pallet.
- Emptying the sump: remove accumulated liquid promptly using safe methods and dispose of it correctly. Do not allow bunds to overflow.
- Housekeeping: label stored liquids, separate incompatibles, and keep access clear for emergency response.
Question: What about outdoor storage and rainwater in the bund?
Solution: Outdoor bunded pallets need a plan for rainfall. Rainwater can reduce available capacity and can become contaminated. Control options include:
- Use covers or locate pallets under a canopy
- Implement a routine pump-out and inspection regime
- Keep drain covers available in case contaminated water needs to be contained during an incident
Always assess the liquid in the sump before disposal. If it is contaminated, it may need handling as controlled waste in line with site procedures.
Question: Can bunded pallets reduce downtime and clean-up costs?
Solution: Yes. Capturing leaks at source prevents spread across floors and into hard-to-clean areas, reducing labour, absorbent use and disruption. It also improves safety by reducing slip risk and helps keep chemical stores audit-ready. Many sites find bunded pallets pay back through fewer incidents and faster routine handling.

For stronger spill prevention, bunded pallets are commonly paired with:
- Spill kits for rapid response near storage and dispensing points
- Drip trays for taps, connectors and small plant leaks
- Drain covers and drain protection to prevent pollution reaching the drainage system
- Bunding and larger secondary containment for higher volume storage
Summary: When should I use bunded pallets?
Solution: Use bunded pallets whenever you store or dispense liquids from drums or IBCs and there is a foreseeable risk of leaks, overfilling or connection failures. They are a practical, scalable way to improve spill control, support environmental compliance expectations, and keep operations cleaner and safer in workshops, yards, chemical stores, and water and wastewater facilities.
