Our most frequently asked questions
How much water do I need to store?
FEMA recommends that "you should store at least one gallon of per person per day."
Example: 4 people for 1 month is 120 gallons. (4 x 30 = 120) This is a bare minimum recommendation.
Consider the following to determine your water needs:
- The number of people you're storing water for.
- If water is required to re-hydrate and cook your food in an emergency.
- Children, nursing mothers and sick people may need more water.
- A medical emergency might require additional water.
- Water needs increase in warmer climates; in very hot temperatures, water needs can double.

How long can I store water?
The American Red Cross recommends rotating water every 6 months for all climates. In a dryer climate, such as Utah or Nevada, fresh water may be stored for 9 to 12 months before rotating. It's best, however, to rotate water more frequently.

Will my water tank freeze?
Water freezes at 32° F or 0° C. If you're worried about your water freezing, drain 10 inches of water from your tank as water expands about 10% when frozen. It's not common for Sure Water tanks to freeze all the way through unless conditions are cold enough for a long time. Many of our water tanks are stored in unheated garages during the winter and rarely have a problem with freezing.
Do I need to treat my water before storing it?
Fresh treated municipal water typically does not need to be treated before storing. However, if your water is from other sources such as wells, streams, rivers, and springs it should be treated before storing. Treating your water properly is important; it helps prevent the growth of bacteria, algae, mold, mildew, and other contaminants from thriving in your water.

Do I need to clean my water tank before filling it?
It's not necessary, but it can be a good idea to clean your tank before using it. Depending on storage conditions and water quality, you may want to wash the tank out again every few seasons.
We have done our best to vacuum out any leftover shavings or other material. Your tank was made at 700° F, thus the likelihood of any living bacteria is very remote.
What are your water tanks made out of?
All our tanks are molded from BPA-free, food-safe, polyethylene composite independently certified by the National Sanitation Foundation (NSF).
Do your tanks have seams?
No. Our water tanks are molded as a one-piece composite and have no seams.
Some ask if there is a seam around the top, there is not. The line that appears to be a seam around the top is a seam in the metal tank mold, not the plastic tank.
What are your water tank dimensions?
260 gallon tank is: 33" L x 28" W x 82" H
525 gallon tank is: 45" diameter x 82" H
How are your tanks made?
Our water tanks are made as one composite piece at 700° F by rotational molding, or rotomolding.
Can I store my water tank outside?
Yes, our tanks are made to be out in the sun. However, shade is preferred; material life and water quality is improved if not stored in direct sunlight.
How are your tanks packaged and shipped?
Our water tanks are cleaned, shrink wrapped, cardboard wrapped, and strapped to a pallet to ship. We use large freight carriers to ship to residential and commercial locations nationwide. For residential destinations, please expect a phone call from the freight carrier for delivery confirmation.
Can I install this water tank in-line with my home water system?
Sure Water storage tanks cannot be pressurized by any water system. Our tanks simply aren't designed to be pressurized. Tanks of this type are for water storage only.
