for guaranteed 5-year storage life¹:

CONTAINER DESCRIPTION

1. Standard Water Storage Containers.

1. CONSTRUCTION: New (unused, or used only for food or water storage since new), blow molded, rigid, all plastic container made of virgin polyethylene resin.

2. Food Grade Materials: Containers must meet the requirements of the Food and Drug Administration (FDA) for items intended for use in contact with food.

3. Closure: Container closures must be heavy-duty threaded plugs or caps sufficient to prevent leakage. Important: The closure must not be vented, and must use a gasket of FDA-approved material to form an air-tight seal. CAUTION: Use only solid caps, plugs or bungs. Do not use pumps, faucets, spigots, etc. as closures--they are NOT airtight.
2. UN & DOT-34 Type Containers.

1. Look for a 'DOT-34' or 'UN' marking. The manufacturer will permanently emboss the container bottom, or side, with these specification markings. These are heavy-duty containers that can withstand abuse and outside storage.
2. In addition to specifications for a standard water container (1A, 1B and 1C above), the DOT-34 or UN specification requires that the containers are tested by the manufacturer, and meet or exceed requirements for the following: Impact, Vibration, Leakage, Static Pressure, and Compression. The containers must also provide ultraviolet (UV) light protection for their contents for the life of the container.

3. WaterCube^TM Containers.

WaterCube^TM Containers are a unique 2-part container of a different design and construction than the common UN or DOT-34 type container or drum. WaterCube^TM complies with a different set rigid specifications designed specifically for 2-part containers, and are designed and approved for 5-year water storage.
