Choosing a Water Storage Tank: 10 Essential Factors to Consider

May 15, 2022 | 4 minute read

Water is a basic need for human beings and many other forms of life. In some parts of the world, clean water may be hard to come by. That’s why people often turn to atmospheric water generators as a way to have a reliable source of water they can depend on in times of need.

Of course, you’ll need a place to store all of that water from air, and that’s where water storage tanks come in. If you’re thinking about buying a water storage tank for your atmospheric water generator, there are a few factors you’ll need to take into account before making your decision.

1. What Will the Water Be Used For?

The first thing you’ll need to consider is what the water is going to be used for. If you’re looking for a water storage tank for drinking water, you’ll want to make sure that it’s made from food-grade materials. Look for tanks that are free of BPAs, phthalates, and other harmful chemicals. You’ll also want to make sure that the tank is designed for potable water storage.

On the other hand, if you’re looking for a water tank to store water for irrigation or other non-drinking uses, you won’t need to worry about finding a food-grade tank. However, you’ll still want to make sure that the tank is made from materials that won’t corrode or leach harmful chemicals into the water.

2. What Materials Are Used in Water Storage Tanks?

Water storage tanks can be made from various materials. Here are some common options:

  • Above-Ground Fiberglass: Lightweight, easy to install, durable, and resistant to UV damage, cracking, dents, and corrosion.
  • Bolted Steel: Often used in commercial and industrial applications for watertight storage.
  • Carbon Welded Steel: Customizable with various interior linings.
  • Corrugated Steel: Affordable and versatile, often used in agriculture.
  • Folding Tanks: Portable solutions for agricultural and military uses.
  • Pillow Tanks: Flexible and adaptable for various applications.
  • Polyethylene: Durable and chemical-resistant for both above-ground and underground storage.
  • Stainless Steel: Corrosion-resistant and durable, often used in commercial settings.
  • Underground Fiberglass: Space-saving option for residential applications.

3. How Much Water From Air Do You Need to Store?

Consider how much water you need to store for your air-to-water system. This will largely be determined by the intended use of the water. For emergency use, a tank with a storage capacity of at least 1,000 gallons is advisable. For watering a garden, a smaller tank with a capacity of around 50 gallons may be sufficient.

How Much Water Does an Average US Home Need?

According to the US Geological Survey, the average American uses between 80 and 100 gallons of water per day, with a family of four averaging 250 gallons. Having a water storage tank that can hold at least a few days’ worth of water is advisable for emergencies.

4. What Are the Dimensions of the Tank?

The size of the tank you need will depend on how much water you need to store and where you plan to store it. Slimline tanks are ideal for underground applications where space is limited, while round or square tanks are better for above-ground storage with more space.

How Do I Measure Tank Size?

Tank size is usually measured in gallons. For example, a 500-gallon round water storage tank can hold up to 500 gallons of water. To find out how many gallons a tank can hold, multiply the diameter by the height and then by 0.0043.

5. What is the Climate Like Where You Live?

The climate in your area will influence your choice of water storage tank. In cold climates, choose materials that can withstand freezing temperatures. In hot climates, choose materials that can keep the water cool.

What Tanks Work Best in Cold Climates?

Polyethylene and fiberglass tanks are good choices for cold climates because they resist cracking and damage from freezing water. Insulate the tank or place it in a heated area to prevent freezing.

What Tanks Work Best in Hot Climates?

Concrete, fiberglass, and metal tanks are good choices for hot climates as they help keep water cool. Fiberglass offers excellent UV protection, preventing algae growth.

6. What is Your Budget?

Water storage tanks can range in price from a few hundred to several thousand dollars. Your budget will help determine which tank is right for you.

How Much Does a Water Storage Tank Cost?

  • Above-Ground Fiberglass Tanks: $500 to $3,000 or more.
  • Underground Fiberglass Tanks: $1,000 to $10,000 or more.
  • Stainless Steel Tanks: $2,000 to $20,000 or more.
  • Polyethylene Tanks: $500 to $5,000 or more.
  • Pillow Tanks: $200 to $2,000 or more.
  • Folding Tanks: $1,000 to $5,000 or more.

7. Where Will the Tank be Located?

Consider whether you need an above-ground or underground tank. Above-ground tanks are easier to install and maintain but can be less aesthetically pleasing. Underground tanks are more durable and less likely to be damaged by severe weather but are more difficult to install and maintain.

8. Do You Need a Pump?

If you need to move water from the tank to another location, a pump will be required. Pumps can range in price from a few hundred to several thousand dollars.

    Gravity-Fed Systems

    Gravity-fed systems rely on gravity to move water from the tank to the point of use. They are less expensive but less efficient and best suited for small-scale water needs.

    Pump-Based Systems

    Pump-based systems use pumps to move water from the tank to the point of use. They are more expensive but more efficient and best suited for large-scale water needs.

    9. How Often Will the Tank Need to be Cleaned?

    Regular cleaning is important to prevent contamination with algae, bacteria, and other microorganisms. Above-ground tanks should be cleaned every two years, and underground tanks every four years.

    10. What is the Cost of Maintenance?

    Water storage tanks require regular cleaning and inspection. The cost of maintenance will depend on the size of the tank, the frequency of cleaning, and the cost of labor, ranging from $100 to $500 per year.

    Is the Tank Covered by a Warranty?

    Most water storage tanks come with a one-year warranty, but some manufacturers offer extended warranties of up to five years. Extended warranties typically cost between 10% and 20% of the purchase price of the tank.

    There are many factors to consider when choosing a water storage tank. By understanding your needs and doing some research, you can find the perfect tank for your property.
