10 Factors to Consider When Buying a Water Storage Tank
Updated: Jun 25
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 that they can depend on in times of need.
Of course, you'll need a place to store all of that water, and that's where water storage tanks come in. If you're thinking about purchasing a water storage tank for your AWG, there are a few factors you'll need to take into account before making your decision.
#1 What is the Water Going to 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.
What Materials are Used in Water Storage Tanks?
There are 9 common types of materials that water storage tanks can be made out of:
Above-Ground Fiberglass - Fiberglass is often used in residential applications because it is lightweight and easy to install. It is renowned for its durability and resistance to UV damage, cracking, dents, and corrosion.
Bolted Steel - These tanks are made from sections of steel that are bolted together. They're often used in commercial and industrial applications because the construction allows for a watertight seal for storing millions of gallons of water.
Carbon Welded Steel - These tanks are made from sections of steel that are welded together. They have a variety of customizable options, including being able to choose which interior lining you would like to have, depending on the use.
Corrugated Steel - Not only are these tanks affordable, but they're also very versatile. They're often used in agricultural applications but can also be used for residential and commercial purposes.
Folding Tanks - If you need a portable solution, folding tanks are a good option. They're often used in agricultural and military applications because they can be easily transported and set up.
Pillow Tanks - Super flexible and adaptable to any situation, pillow tanks are often used in a variety of applications, including agricultural, industrial, and commercial.
Polyethylene - Polyethylene plastic is often used in water storage tanks because it is durable and resistant to chemicals. It's a good choice for both above-ground and underground storage.
Stainless Steel - If you're looking for a material that is corrosion-resistant, stainless steel might be the right choice for you. These tanks are often used in commercial applications because of their durability.
Underground Fiberglass - If you need to save space, fiberglass underground tanks are a good option. They're often used in residential applications because they're easy to install and don't take up a lot of space.
#2 How Much Water do You Need to Store?
The next thing you'll need to think about is how much water you need to be able to store. This will largely be determined by the intended use of the water.
For example, if you're looking for a water storage tank to use in case of an emergency, you'll likely want to choose a tank that has a storage capacity of at least 1,000 gallons. On the other hand, if you're just looking for a way to store water for watering your 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 family uses between 80 and 100 gallons of water per day. Of course, this number will vary depending on the size of your family and how much water you use for things like bathing, laundry, dishwashing, and other incidentals.
It's a good idea to have a water storage tank that can hold at least a few days' worth of water, just in case you experience a power outage or other emergency that prevents you from being able to access clean water.
#3 What are the Dimensions of the Tank?
The size of the tank you'll need will also be determined by how much water you need to store and where you plan on storing it. For example, if you need to store a large amount of water but don't have a lot of space to work with, you may want to choose a slimline water tank.
These types of tanks are often used in underground applications where space is limited. On the other hand, if you have plenty of space but don't need to store a lot of water, a round or square tank may be a better option.
How Do I Measure Tank Size?
The size of the tank is usually measured in gallons. For example, a common size for a round water storage tank is 500 gallons. This means that the tank can hold up to 500 gallons of water at a time.
To find out how many gallons a particular tank can hold, you'll need to know the dimensions of the tank. The dimensions are usually listed in the form of Diameter x Height, such as 30"D x 60"H.
To calculate the storage capacity in gallons, you'll need to multiply the diameter by the height and then by 0.0043. This will give you the approximate capacity in gallons.
For example, a tank with dimensions of 30"D x 60"H has a capacity of approximately 1,000 gallons (30 x 60 x 0.0043 = 1,000).
What is the Shape of the Tank?
Water storage tanks come in a variety of shapes, including round, square, and slimline. The shape of the tank you choose will largely be determined by where you plan on storing it and how much water you need to store.
For example, round tanks are often used in above-ground applications because they're easy to transport and can be placed just about anywhere. Square tanks are also popular for above-ground storage, but they're not as easy to transport as round tanks. And, slimline tanks are often used in underground applications because they don't take up a lot of space.
#4 What is the Climate Like Where You Live?
The climate in your area will also play a role in choosing the right water storage tank. If you live in an area with very cold winters, you'll want to make sure you choose a tank that's made from materials that can withstand the cold temperatures. Similarly, if you live in a hot region, you will want a material that can keep the water cool.
What Tanks Work Best in Cold Climates?
Tanks made from materials like polyethylene or fiberglass are good choices for storing water in cold climates. These materials are resistant to cracking and other damage that can occur if the water freezes.
To keep a tank from freezing in very cold weather, you may need to take some extra steps, such as insulating the tank or placing it in a heated area.
What Tanks Work Best in Hot Climates?
Tanks made from materials like concrete, fiberglass, or metal are good choices for hot climates. These materials can help keep the water inside the tank cool, even in direct sunlight.
Fiberglass offers excellent UV protection, so it's a good choice if you're looking for a material that can withstand direct sunlight. This can also help prevent algae growth in the tank.
To keep a tank from overheating in very warm weather, you may need to take some extra steps, such as placing it in a shady area or adding a water cooler to the system.
#5 What is Your Budget?
Of course, you'll also need to consider your budget when choosing a water storage tank. Water storage tanks can range in price from a few hundred dollars to several thousand dollars, so it's important to choose one that fits within your budget.
How Much Does a Water Storage Tank Cost?
Water storage tanks can range in price from a few hundred dollars to several thousand dollars, depending on the size and material of the tank. Some ballpark figures for common tank sizes are:
Above-ground fiberglass tanks start at around $500 to $3,000 or more for larger sizes.
Underground fiberglass tanks start at around $1,000 to $10,000 or more for larger sizes.
Stainless steel tanks start at around $2,000 to $20,000 or more for larger sizes.
Polyethylene tanks start at around $500 to $5,000 or more for larger sizes.
Pillow tanks start at around $200 to $2,000 or more for larger sizes.
Folding tanks start at around $1,000 to $5,000 or more for larger sizes.
#6 Where Will the Tank be Located?
The location of the tank is also an important consideration. Water storage tanks can be placed above-ground or underground, depending on your needs.
Above-Ground Water Storage Tanks
Above-ground water storage tanks are typically less expensive than underground tanks and can be placed just about anywhere on your property. They're also easy to install and maintain.
The main downside of above-ground tanks is that they're not as aesthetically pleasing as underground tanks and they can be more vulnerable to damage from severe weather.
Underground Water Storage Tanks
Underground water storage tanks are more expensive than above-ground tanks, but they're also more durable and less likely to be damaged by severe weather.
The main downside of underground tanks is that they're more difficult to install and maintain. They also take up more space than above-ground tanks.
#7 Do You Need a Pump?
Another important consideration is whether or not you need a pump. If your goal is simply to store water for future use, then a pump may not be necessary. However, if you need to move water from the tank to another location (for irrigation or other purposes), then a pump will be required. Pumps can range in price from a few hundred dollars to several thousand dollars, so be sure to factor this into your budget.
If you have the space for it, then you can opt for a gravity-fed system. These systems rely on gravity to move water from the tank to the point of use. Gravity-fed systems are typically less expensive than pump-based systems, but they're also less efficient. Gravity-fed systems are best suited for small-scale water needs.
If you need to move water over a long distance or to a height greater than the tank, then you'll need a pump-based system. These systems use pumps to move water from the tank to the point of use. Pump-based systems are more expensive than gravity-fed systems, but they're also more efficient. Pump-based systems are best suited for large-scale water needs.
#8 How Often Will the Tank Need to be Cleaned?
Another important consideration is how often the tank will need to be cleaned. Water storage tanks can become contaminated with algae, bacteria, and other microorganisms over time. These contaminants can make the water unsafe to drink.
To keep the water safe, it's important to clean the tank on a regular basis. The frequency of cleaning will depend on the size of the tank, the amount of use, and the quality of the water.
As a general rule of thumb, above-ground tanks should be cleaned every two years and underground tanks should be cleaned every four years.
#9 What is the Cost of Maintenance?
In addition to the initial cost of the tank, you'll also need to budget for the cost of maintenance. Water storage tanks require regular cleaning and inspection to ensure that they're in good working condition.
The cost of maintenance will depend on the size of the tank, the frequency of cleaning, and the cost of labor. As a general rule of thumb, you can expect to spend between $100 and $500 per year on maintenance.
#10 Is the Tank Covered by a Warranty?
Finally, be sure to ask if the tank is 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.
Be sure to read the fine print before you purchase a warranty. Some warranties only cover defects in materials and workmanship, while others also cover damage from weather, insects, and other causes.
