Collapsible Water Tank Sizing
These collapsible water tanks are available in numerous capacities ranging from 25 gallons up to a possible 210,000 gallons. If you require a larger size and have the available space, we can help you create a bladder system to store essentially an infinite amount of water. This requires very little additional equipment and installation effort.
The dimensions listed below are accurate based on a bladder filled to capacity. The bags can be easily folded to a extremely compact size for convenient storage when emptied out. Depending on the fittings/valves installed, usually the tanks can reduce down to as little as 4% of the total capacity size.

Technical Specifications
Fabric: The variety of fabrics used to construct these collapsible water tanks is designed specifically for potable water and contains NSF 61 and FDA approved materials. Typical fabrics include polyurethane, polymer alloy and PVC constructed materials. If you have specs that call for a particular material to be used for the collapsible tanks construction, let us know. We may be able to custom design a collapsible tank specifically for your needs.
Tank Lifespan: The contact time for these collapsible water tanks can vary depending on the material type selected as well as the usage and environment in which it is installed. Lifespan is commonly up to a maximum of 7 years. At this time the material will begin to degrade and is no longer appropriate for storage. The low cost and biodegradable/recyclable design make purchasing a replacement bladder an ideal solution for longer period storage.
Fittings: Standard fittings for these collapsible water tanks are made from an aluminum, stainless steel or polypropylene (plastic). The sizes typically range from 3/4" through 2". Fittings include ball valves, pressure relief vents and caps to accommodate various hoses and pumps. Custom sized fittings are also available upon request.
Optional Accessories Also Available:
- Emergency Plugs
- Repair Kits
- Pressure Relief Valves
- Ports (drain and floor available)
- Additional Fittings, Valves, etc.
