Emergency Water Storage at Home

A bathtub water bladder is a liner you fill in the tub when a storm or outage is on the way. We don't sell bathtub bladders. For drinking water you can store ahead of time, we carry SITE TANKS potable Pillow Water Tanks: flat, rectangular bladders that fold flat when empty and fill where they sit. A 100 gallon pillow tank is longer than a standard bathtub, so set it on a level floor, garage slab or patio instead.

Pillow tanks are a practical backup for natural disasters, power outages, or unexpected water shortages. Fill one with treated tap water before storm season and keep it on a clean, level surface away from sharp edges.

Collapsible Bladder Tank Design

The design of a collapsible tank has helped to increase flexibility and storage use for emergency situations. Collapsible tanks are designed to lie flat when empty, allowing them to be folded until their necessary storage time. Once in place, these tanks can be filled for safe water storage in their required locations.

Our pillow tanks range from 25 to 250,000 gallons. For household emergency storage, smaller capacities, typically between 80 and 100 gallons, meet the water needs of most individual households. The 100 Gallon SITE TANKS Potable Water Pillow Tank fits that range, and potable models also come in 25, 50, 150 and 200 gallons.

For drinking water, choose a potable model: its resin is certified to NSF 61. Non-potable models are for wash water, irrigation and firefighting supply. The 100 gallon potable tank has two 4" fill ports, a 2" vent port and a 4" drain.

There are several advantages to using a pillow tank as an emergency storage vessel. Compare all sizes on our Pillow Water Tanks page. Some of the benefits most enjoyed by customers using this type of storage include the following:

  • Easily Moved: Tanks lie completely flat when they are empty, so they can be rolled or folded and carried to a new location.
  • Easily Stored: Folded tanks fit in a box or on a shelf until the emergency need arises.
  • High in Strength: The fabric holds water on any flat, level surface, indoors or outdoors.
  • Filled in Place: Put the tank where it will stay before you fill it. A full tank is not meant to be moved, and it should never be filled past its maximum fill height.
