Collapsible Drinking Water Tanks
Collapsible Tanks for drinking water are the easiest and most economical way to contain potable water. Constructed from a flexible fabric material, our collapsible tanks can fit in the most hard to reach spaces and when filled, will stay low in profile. These collapsible water tanks fold flat for storage and are lightweight for easy shipping. Their versatility and easy installation has made them perfect for industrial, commercial and residential areas. Standard sizes and capacities for the tank can be seen below. Custom sizes and dimensions may also be available on request. All collapsible water tanks are made in the USA, with NSF and FDA approved liners.
Small Capacity Pillow Tanks range in size from 25 gallons to 5,000 gallons and are ideal for small storage requirements including:
- Emergency Drinking Water Storage
- Home Storage
- Hospital Drinking Water Supply
- Construction Site Water Storage
- Smaller Military Operations
- Remote Area Storage

Large Capacity Tanks start in a 5,500 gallon size and go up in size to 210,000 gallons. Due to the large volume of many of these units, fabrics used on the tank are typically heavier in weight and rated to handle higher water amounts. Uses include:
- Industrial Water Storage
- Large Military Applications
- Facility Water Supply
- Commercial Businesses
- Recreational Facilities (Hotels, RV Locations, Motels, Complexes)
- Aqua Farming
- Agricultural Facilities
Technical Specifications
Fabric: Collapsible tanks are made using first-grade materials and are built to match the specific liquid you are intending to store. Collapsible tanks storing drinking water are built to FDA and NSF 61 standards to ensure that your potable water is safe for consumption.
Contact Time: When choosing a drinking water pillow tank, different fabrics can be used to meet your specific requirements. Tanks will typically be offered with a contact time within the range of 1 to 7 years. It should be noted that the contact time is rated by the fabric chosen to make your tank for weathering or chemical processes. This has no bearing on the longevity of the tank.
Fittings: Standard fittings for our pillow tanks are a 2" bulkhead with cap and nipple. Adapters may be added to the fittings to match hoses and other water sources. Larger size fittings are additionally available upon request, so please ask!
