Expert Insights
Frequently Asked Questions
650-Gal. Flexible Secondary Containment Tank NO Drain
How many IBC totes or drums fit in the 650-gallon containment?
The 102" x 72" footprint accommodates two standard 275-gallon IBC totes side by side, or up to twelve 55-gallon drums arranged in two rows of six. The 650-gallon capacity exceeds 110% containment for the largest single container.
Why choose the 650-gallon over the 400-gallon model?
The 650-gallon model is 24 inches wider (72" vs 48"), providing more floor area for larger equipment or multiple containers. Choose the 650-gallon when your equipment footprint exceeds 48 inches in width or you need containment for multiple IBC totes.
Can this tank be used on gravel or uneven surfaces?
Yes, the flexible PVC material conforms to minor surface irregularities. For gravel surfaces, place a protective liner or geotextile fabric underneath to prevent puncture from sharp stones. Level the surface as much as possible for maximum containment volume.
How do I remove accumulated rainwater without a drain?
Use a portable sump pump or manual hand pump to remove water. Always inspect collected water for contamination before disposal. If a sheen or discoloration is present, the water must be disposed of as contaminated waste per EPA regulations.
What is the expected service life of the 18 oz PVC material?
With proper care, 18 oz PVC flexible containment typically lasts 5-10 years in outdoor applications. UV exposure, chemical contact, and mechanical abrasion affect lifespan. Regular inspection for cracks, tears, or degradation is recommended.
