Choosing the Right Size Water Storage Tank for Your Needs

Having access to a plentiful, reliable supply of water is an essential for any home or business. Whether it’s for drinking, gardening, or other uses, having a reliable water supply is essential. One of the best ways to ensure an adequate water supply is to install a water storage tank. But, how big should your water storage tank be?

No matter what your water storage needs are, this guide will provide the knowledge needed to make the right decision. So, let’s get started!

How Many Gallons of Water Storage Do I Need?

When it comes to determining the size of a water storage tank you need, the first step is to calculate the total amount of water you will need to store. This can be done by calculating the number of people you are storing water for and the length of time you need to be prepared for.


According to the Federal Emergency Management Agency (FEMA), you should have at least one gallon of water per person, per day for minimum survival. For example, if you are storing water for four people you will need a minimum of 4 gallons of water a day, and say you need to store it for 10 days, you would need a tank that can hold at least 40 gallons.


Once you have determined the total amount of water you need to store, you can then look at the different types of water tanks available to find one that can hold the required amount of water. Water tanks come in a range of sizes, from small tanks that hold around 35 gallons, to large tanks that can hold thousands of gallons.


When selecting a water tank, it’s important to take into account the space you have available for a tank, as well as the cost of the tank and any accessories that may be required. It’s also important to consider the environmental impact of the tank, as some tanks may be more energy-efficient than others. Once you have all this information, you can then make an informed decision on the size of the tank you need.

Where's the Best Place to Put Your Water Storage Tank?


The best place to put your water storage tank depends on the size of the tank and the space you have available. Generally, it is best to place the tank in an area that is out of the way, such as a basement or garage. You also want to store it in a cool dark environment out of direct sunlight. This will help to reduce the visual impact of the tank, provide protection from the elements and prevent any microbial growth.


If you do not have an area that is suitable for a water tank, you may need to consider other options, such as installing a tank outdoors. When installing a tank outdoors, it is important to ensure that the tank is placed on a level, solid surface and is well-secured to prevent it from moving or tipping over. It is also important to make sure that the tank is placed in an area that is safe from flooding and other weather hazards.

What's the Ideal Water Storage Tank Material?


The ideal material for a water storage tank will depend on the purpose of the tank and the environment in which it will be placed. Generally, tanks made from plastic, concrete, or fiberglass are the most common materials used for water storage.


Plastic tanks are lightweight, durable, and easy to install, making them a popular choice for most applications. Concrete tanks are more expensive, but they are also very durable and can last for many years. Fiberglass tanks are the most expensive option, but they are also the most resistant to corrosion, making them a good choice for areas prone to harsh weather.




Determining the size of your water storage tank is an important decision that should be made with careful consideration. Factors such as the size of your home, the number of people living in your household, the type of water supply, and the purpose of the tank should all be taken into account when selecting the size of your water storage tank. By understanding how much water your household uses and how much water the CDC recommends, you can make an informed decision about the size of the tank that will meet your household’s water needs. With the right size tank, you can be sure that your water supply will remain secure, reliable, and safe.

Thank you for mentioning that figuring out how much water you will need to store overall is the first step in figuring out what size water storage tank you require. I’ll be sure to share this with my cousin, who has been preparing to get a water tank for her house. I’ll also look into experts who can assist her with installing one. I appreciate you sharing!
