Choosing a polyethylene secondary containment sump starts with the spill scenario: a large tank skid needs a very different footprint and capacity from a drum station or a workbench. I rank the Enpac 550-Gallon Polyethylene Tank Containment Sump first for large skid tanks, while the Enpac 275-Gallon model is the more space-conscious tank option. For drum storage, the Global Industrial sump holds four 55-gallon drums; the compact Eagle tray is aimed at drips and small spills, not bulk containment.

The central tradeoff is capacity versus fit. Larger sumps provide a containment basin for bigger equipment or more containers, but take up more floor space and may require optional accessories. Smaller trays are easier to place and store, yet cannot substitute for a tank or drum sump. I compare these four by matching their documented use, dimensions, material, and limitations to the buyer’s likely application.

Key Takeaways
- For one 550-gallon skid tank, the Enpac 550-Gallon model offers the largest listed containment capacity, but its 113 × 71-inch footprint demands substantial space.
- The Enpac 275-Gallon sump is the more compact of the two tank-specific Enpac options and is designed for one 275-gallon obround tank.
- The Global Industrial sump is the lineup’s drum-storage choice: it holds four 55-gallon drums and has an 85-gallon sump capacity.
- The Eagle tray weighs six pounds and stacks for storage, but its five-gallon sump capacity suits minor drips rather than tank or drum spill containment.
- Optional drains, trickle filters, and tarps are not included as standard features on the Enpac tank sumps; verify accessory needs before choosing.

Enpac 550-Gallon Polyethylene Tank Containment Sump, Black
I put the Enpac 550-Gallon sump first because it is the clearest match for a large tank-skid containment job. It is designed for one 550-gallon skid tank, or 150- and 300-gallon elevated skid tanks, and its 550-gallon capacity makes it the largest stated tank sump in this group. The roomy interior also leaves space for hoses and related equipment, which is useful where a tank setup includes more than the tank alone.
Compared with the 275-gallon Enpac, this unit suits larger tanks and brings a much bigger footprint: 113 × 71 inches rather than 78.5 × 41.5 inches. That is a meaningful difference for a farm, marine area, or construction site with room to dedicate to containment, but it makes this a poor default for cramped indoor layouts. At 171 pounds, it is also a substantial piece of equipment to plan around during placement.
The polyethylene construction resists rust and corrosion, and the supplied product information cites EPA 40 CFR 264.175, SPCC, and NPDES. Those references do not replace checking the requirements for a specific site or use. A drain is optional, and a trickle-filter retrofit needs support underneath, so buyers who want either feature should plan for the added parts and installation details. Against the Global drum sump, this is the better fit for a single large skid tank, not a four-drum station.
Pros:- Designed for one 550-gallon skid tank or specified elevated skid tanks
- 550-gallon stated containment capacity
- Large interior accommodates hoses and related equipment
- Polyethylene resists rust and corrosion
Cons:- Large 113 × 71-inch footprint needs substantial space
- Drain is optional
- Trickle-filter retrofit requires support underneath
Best for: Sites containing one 550-gallon skid tank, or specified smaller elevated skid tanks, with enough floor space for a large basin.
Not ideal for: Buyers with limited installation space, drum-only storage, or a need for a drain or trickle filter included as standard.
- Capacity:550 gallons
- Material:Polyethylene (PE)
- Compatible tanks:One 550-gallon skid tank or 150- and 300-gallon elevated skid tanks
- Dimensions:113 × 71 × 32 in.
- Weight:171 lb
- Color:Black
- Model:5550-BK
- Warranty:1-year limited
- Regulations listed:EPA 40 CFR 264.175, SPCC, NPDES
Our verdict“I recommend this as the strongest tank-specific choice when a large skid tank and its associated equipment need a dedicated containment basin.”
Enpac Poly Tank Containment Sump, 275-Gallon
For a 275-gallon obround tank, I prefer this Enpac over the larger model because its tank-specific fit comes in a substantially smaller footprint. The 78.5 × 41.5-inch basin is still a dedicated installation, but it uses less floor area than the 550-gallon Enpac and is described as allowing access to both the tank and pump. That can make routine operation less awkward than a basin that simply surrounds equipment without attention to access.
Its 275-gallon capacity and one-tank compatibility give it a narrower role than the top-ranked Enpac. Buyers with a 550-gallon skid tank should not treat it as a smaller version that will fit any tank; the stated match is one 275-gallon obround tank. Compared with the Global Industrial model, this is a better fit for the specified tank shape, while the Global unit is designed around four 55-gallon drums.
Like its larger sibling, the sump is made from corrosion-resistant polyethylene, and the listed regulatory references include EPA 40 CFR 264.175, SPCC, and NPDES. A drain, trickle filter, and tarp are optional, not standard inclusions. The trickle filter also needs support underneath. I would choose this when tank fit and a more manageable footprint matter more than the extra capacity of the 550-gallon unit, but I would skip it if accessory requirements have not been priced and planned separately.
Pros:- Designed for one 275-gallon obround tank
- Smaller footprint than the 550-gallon Enpac
- Allows access to the tank and pump
- Polyethylene construction resists rust and corrosion
Cons:- Compatibility is specified for a 275-gallon obround tank
- Drain, filter, and tarp are optional
- Trickle filter requires support underneath
Best for: A buyer containing one 275-gallon obround tank who wants a tank-and-pump-accessible basin with a smaller footprint than the 550-gallon Enpac.
Not ideal for: Owners of larger skid tanks, drum-storage operations, or buyers who need optional drainage or filtration included.
- Capacity:275 gallons
- Material:Polyethylene
- Tank compatibility:One 275-gallon obround tank
- Dimensions:78.5 × 41.5 × 33 in.
- Weight:98 lb
- Color:Black
- Model:5275-BK
- Optional features:Drain, trickle filter, and tarp
- Regulations listed:EPA 40 CFR 264.175, SPCC, NPDES
Our verdict“I would choose this over the larger Enpac when the tank is a 275-gallon obround model and saved floor space matters.”
Global Industrial Spill Containment Sump with Wire Deck
The Global Industrial sump is the lineup’s dedicated drum-storage option. It holds four 55-gallon drums and has an 85-gallon sump capacity, making it a more relevant comparison for a drum station than either Enpac tank basin. Its 50.5-inch-square footprint is also much smaller than the 550-gallon Enpac’s long rectangular basin, although it serves a different arrangement rather than replacing a tank-specific sump.
The unit is made from chemical-resistant HDPE and fits common 48 × 48-inch or 40 × 48-inch pallet sizes. It nests for more compact storage when not in use, a practical distinction from the large Enpac models. The stated static load capacity is 4,000 pounds, but buyers should match the actual loaded setup to the product’s limits and installation instructions rather than infer suitability from the number alone.
There are handling constraints that matter in a working facility: forklift pockets are for transporting the empty sump only, and the sump must not be stacked while drums are in it. That makes it less convenient for moving a loaded station than its pockets might suggest. Compared with the Eagle tray, it is built around multiple full-size drums and far greater spill capacity; compared with the Enpac units, it is not the right shape or stated application for a skid tank.
Pros:- Designed to hold four 55-gallon drums
- 85-gallon sump capacity
- Nests for compact storage
- Fits listed common pallet sizes
Cons:- Forklift pockets are for empty-sump transport only
- Must not be stacked while in use with drums
- Not designed as a tank-skid containment basin
Best for: Facilities storing four 55-gallon drums in a compact, nestable polyethylene containment sump.
Not ideal for: Tank-skid owners, anyone needing to forklift the sump while loaded, or operations that plan to stack units in use.
- Sump capacity:85 gallons
- Drum capacity:Four 55-gallon drums
- Material:High-density polyethylene
- Dimensions:50.5 × 50.5 × 15.88 in.
- Static load capacity:4,000 lb
- Compatible pallet sizes:48 × 48 in. or 40 × 48 in.
- Weight:54.5 lb
- Model:298441
Our verdict“I rank this as the best match for a four-drum station, but its empty-only forklift guidance rules out loaded transport.”
Eagle Spill Containment Utility Tray, 5-Gallon Sump
The Eagle is the easiest option here to place and store, but it is also the one with the narrowest containment role. This five-gallon utility tray is intended for everyday drips and small spills under containers or equipment, not for a large tank or a row of drums. Its ribbed bottom elevates containers above collected liquid, helping keep them out of the pooled spill while the tray catches minor leakage.
At 36.25 × 18.25 × 2.38 inches and six pounds, it is far more manageable than either Enpac basin or the Global drum sump. The tray is lightweight and stackable, so it can suit a workshop, laboratory, or maintenance area that needs movable protection at individual work points. Its HDPE construction is described as resistant to many chemicals, corrosion, and impacts; buyers still need to verify compatibility for the specific liquid being handled.
Compared with the Global Industrial model, the Eagle is a small-spill tray rather than a four-drum containment station. It is not a budget-sized substitute for the 275- or 550-gallon Enpac sumps, because the stated capacities and intended applications differ dramatically. I would select it for localized drips and easy storage, and skip it anywhere the plan depends on containing a substantial release.
Pros:- Lightweight at six pounds and stackable for storage
- Ribbed bottom raises containers above collected liquid
- HDPE construction resists many chemicals, corrosion, and impacts
- Compact footprint suits localized drip protection
Cons:- Five-gallon capacity is limited to small spills
- Not a substitute for tank or drum containment
- Chemical compatibility must be checked for the liquid in use
Best for: Workshops, laboratories, and maintenance areas needing a lightweight tray beneath equipment or containers that may produce minor drips.
Not ideal for: Tank-skid or multi-drum containment, or any application that requires a large-volume secondary containment basin.
- Sump capacity:5 gallons
- Material:High-density polyethylene (HDPE)
- Dimensions:36.25 × 18.25 × 2.38 in.
- Weight:6 lb
- Color:Yellow
- Model:1677
- Country of origin:USA
Our verdict“I recommend this only for localized drips where portability and storage matter more than spill capacity.”
How We Picked
I ranked these products by how clearly their capacity and form factor match a containment job, not by treating every polyethylene tray as interchangeable. The Enpac models are purpose-built around particular skid tanks, the Global Industrial unit is configured for drums, and the Eagle tray addresses small, routine drips. That distinction drives the order: the 550-gallon Enpac is the strongest fit for a large tank application, followed by the smaller tank-specific Enpac, the drum sump, and finally the utility tray.
I also compared the listed dimensions, material, access, and handling limits. High-density polyethylene and polyethylene construction are relevant for corrosion resistance, but material alone does not prove compatibility with every chemical. Buyers should check the manufacturer’s chemical-compatibility guidance and the rules that apply to their site and liquid. Where regulatory references are supplied, I report them as product information rather than treating them as a guarantee that a particular installation complies.
Finally, I weighed practical drawbacks alongside the intended use. A large basin can be a poor fit where floor space is tight; a low-profile tray cannot contain the same scale of release as a tank sump; and accessories listed as optional should not be assumed to come in the box. The product descriptions do not provide enough information to compare every installation detail or chemical rating, so I avoid filling those gaps with assumptions.

Factors to Consider When Choosing Polyethylene Secondary Containment Sump
I would begin with the item the sump must contain, then check capacity, available floor space, and accessory requirements. These products serve different scales, so comparing them as if they were interchangeable trays can lead to a poor fit.
Match the sump to the container
Tank shape and listed compatibility come first. The 550-gallon Enpac is specified for one 550-gallon skid tank or certain elevated skid tanks; the 275-gallon Enpac is specified for one 275-gallon obround tank. The Global unit is designed for four 55-gallon drums. The Eagle tray is for localized drips and small spills, not full-size tank or drum storage. Check the equipment dimensions and support arrangement against the manufacturer’s information before ordering.
Read capacity in context
A stated sump capacity is useful, but it does not answer every compliance or site-planning question on its own. The Enpac options list 550 and 275 gallons, the Global sump lists 85 gallons, and the Eagle tray lists five gallons. Choose capacity for the release scenario and applicable rules, not simply the biggest number that fits the budget or floor plan. Ask a qualified environmental or safety professional about requirements for the liquids and site involved.
Measure the installation area
The 550-gallon Enpac needs a 113 × 71-inch area, far more than the 78.5 × 41.5-inch footprint of its 275-gallon sibling. The Global unit is 50.5 inches square, while the Eagle is a low-profile 36.25 × 18.25-inch tray. Leave room for access and normal operation, not only the basin’s outside dimensions. Tank and pump access is specifically described for the 275-gallon Enpac, while the large model offers interior room for hoses and related equipment.
Check accessories and handling limits
Neither Enpac tank sump should be assumed to include every accessory: drains are optional, and the 275-gallon model also lists a tarp and trickle filter as optional. The trickle-filter retrofit requires support underneath. On the Global unit, forklift pockets are for moving the empty sump, and the unit must not be stacked while in use with drums. Plan these details before installation, especially if drainage, filtration, or material handling is part of the workflow.
Verify material compatibility and site rules
Polyethylene or HDPE construction offers corrosion resistance, but that does not establish compatibility with every chemical. Check manufacturer guidance for the exact liquid, concentration, and operating conditions. The Enpac descriptions list EPA 40 CFR 264.175, SPCC, and NPDES; those references are product details, not a promise that an installation meets every applicable requirement. Confirm local and site-specific obligations before putting a sump into service.
Frequently Asked Questions
Which product is best for a 550-gallon skid tank?
The Enpac 550-Gallon Polyethylene Tank Containment Sump is the direct match in this lineup. It is specified for one 550-gallon skid tank and has a 550-gallon capacity. Its large 113 × 71-inch footprint is the tradeoff, so measure the installation area and verify the tank arrangement before selecting it.
Can the Enpac 275-gallon sump hold any 275-gallon tank?
The supplied description specifies compatibility with one 275-gallon obround tank, not every tank of that capacity or shape. I would compare the tank’s dimensions and configuration with the manufacturer’s fit information before purchase. Its smaller footprint than the 550-gallon Enpac is useful only if the specific tank fits as intended.
Is the Eagle utility tray suitable for drum storage?
The Eagle tray is described for everyday drips and small spills and has a five-gallon sump capacity. It is not presented as a four-drum station or a tank-skid basin. For four 55-gallon drums, the Global Industrial sump is the option in this comparison designed for that arrangement.
Are drains and trickle filters included with the Enpac sumps?
The product information lists drains as optional, and the 275-gallon model also lists a trickle filter and tarp as optional features. A trickle-filter retrofit requires support underneath. Check the exact configuration and included components before ordering rather than assuming these additions come with the basic sump.
Can I move the Global Industrial sump with drums inside using a forklift?
No. The listed handling guidance says the forklift pockets are intended for transporting the empty sump only. It also says the sump must not be stacked while in use with drums. Plan movement and storage around those limits, and follow the product instructions for the loaded setup.
Conclusion
For a large skid tank, I would choose the Enpac 550-Gallon sump if the installation area can accommodate its footprint. For a compatible 275-gallon obround tank, the smaller Enpac is the more space-conscious tank-specific pick. Drum operators should look to the Global Industrial sump for its four-drum layout, while workshops that need only a tray for minor drips can choose the lightweight Eagle. I would not use the Eagle as a substitute for bulk containment, and I would confirm chemical compatibility, site rules, and any accessory needs before putting any of these options into service.
