✓ Flexible, Collapsible Site Storage

Bladder Tanks

A bladder tank, also known as a pillow tank, is a flexible, collapsible fabric tank built for liquid storage without permanent infrastructure. It ships flat, deploys on a prepared ground surface, and collapses again when empty, making it the practical choice for site water storage, temporary holding, and remote or rotating locations.

Bladder tanks are available for potable water, non-potable water, gray water, and food-grade liquids, with capacities ranging from small portable units to large-scale site installations. Fabric type, capacity, and fittings are all specified to the application and stored liquid.

Bladder Tank Details

Bladder tanks are built from engineered coated fabrics matched to the stored liquid. PVC is standard for non-potable water and general site storage. Polyurethane-coated fabrics are used for potable water and more demanding applications. Every tank ships 100% tested.

Placement requires a level, stable surface clear of rocks and debris. Ground cloths and protective liners can be used beneath the tank where the substrate is abrasive or uneven. Fitting locations and sizes are customizable, with common options including inlet, outlet, vent, and overflow in FNPT configurations.

Configurations are available to rent or purchase depending on project duration. Lead times vary by manufacturer and tank size and are confirmed as part of the quote process.

Frequently Asked Questions

Common questions about bladder tanks. If your question isn't covered here, reach out and a Sales Specialist will help.

What is a Bladder Tank? Is it the same as a Pillow Tank?

Yes. A bladder tank and a pillow tank are the same product. "Pillow tank" refers to the low, rounded shape the tank takes when filled. "Bladder tank" is the broader industry term for the product category. Both names are used interchangeably by manufacturers and buyers. The right configuration, including fabric material, capacity, and fittings, is determined by the stored liquid and intended use, not by which name is used.

What surface does a Bladder Tank need to be placed on?

A level, stable surface clear of sharp objects, rocks, and debris is the standard requirement. A protective ground cloth or liner can be placed beneath the tank to protect the fabric from abrasive substrate. Larger installations may require minor grading or a prepared pad depending on tank size and deployment duration. Share your site conditions when requesting a quote and we will factor that into the recommendation.

What liquids can a bladder tank store?

Bladder tanks are available for fuel, potable water, non-potable water, gray water, and food-grade liquids. The fabric material is selected based on the stored liquid. PVC is common for non-potable and general site storage; polyurethane-coated fabrics are used for potable water and more demanding applications. Material compatibility must be confirmed before ordering. Share your liquid details when requesting a quote and we will confirm the right configuration.

Are Bladder Tanks available to rent or to only rent?

Both options are available depending on the manufacturer and configuration. Rental suits short-term or one-time projects. Purchase makes more sense for recurring use or longer deployments. Let us know your project duration and use case when requesting a quote and we will advise on the right approach.
