Expert Insights

The 1150-gallon model provides containment for the largest portable applications — multiple IBC totes, transformer pads, or large generator sets. At 162" x 78", it offers over 87 square feet of containment area. The no-drain design eliminates any risk of accidental contaminated discharge, which is critical for facilities near waterways or with strict environmental permits. Despite the large capacity, at 80 lbs it remains transportable by two workers and folds flat for storage. For large containment areas exposed to rain, plan for regular pump-out scheduling to maintain full capacity. Use ground-level dunnage or grating inside to protect the PVC floor from heavy equipment.

Frequently Asked Questions

What is the footprint of the 1150-gallon containment?

The outside dimensions are 162" L x 78" W x 24" H, which is approximately 13.5 feet by 6.5 feet. This provides over 87 square feet of containment area for large equipment, multiple IBC totes, or drum storage configurations.

How many containers can fit inside the 1150-gallon model?

The footprint accommodates up to four 275-gallon IBC totes or approximately twenty 55-gallon drums. At 1150 gallons, it provides 110% containment for the largest single container placed inside, meeting EPA SPCC requirements.

Can two workers set up this tank?

Yes. Despite its large size, the tank weighs 80 lbs and uses the same L-bracket corner system as smaller models. Two workers can unfold and assemble it in approximately 10-15 minutes without tools.

How do I manage rainwater in the no-drain model?

Use a portable electric or manual pump to remove accumulated rainwater. Schedule regular pump-outs during rainy seasons. Always inspect water for oil sheens before disposal. Contaminated water must be properly disposed of per EPA regulations.

Is this suitable for transformer containment?

Yes. The 1150-gallon capacity and 13.5 ft x 6.5 ft footprint accommodate most pad-mounted transformers. Many facilities use flexible containment tanks as an economical alternative to poured concrete containment berms for transformer secondary containment.
