Water Tanks: Everything You Need To Know

Water–we drink it and use it for cooking, showering, laundry, and washing the dishes, among other things. And as one of the most important resources, having a continuous supply of water is necessary for our daily lives. 

Most homeowners get their water from the municipal reservoir. However, even the most reliable water reservoirs experience water interruption every now and then. In that case, a water tank is a good alternative water source. 

If you’re thinking of getting a water tank for your home or commercial property, this article will teach you the fundamentals of water storage tanks.

What Is A Water Tank?

A water tank is exactly what it says in its name–it’s a tank that stores water. It’s simply a specially designed container that collects and stores water for later use. In general, you’ll find all sorts of water tanks today. Manufacturers and suppliers like The Tank Factory offer water tanks in all shapes, colors, sizes, forms, and configurations. If you’d like to look at their product selection, you can do so here

From huge well-pressurized tanks that are commonly used by local municipal reservoirs to small tanks that can be installed under your sinks, water tanks are a vital part of most home water systems. 

Uses Of Water Tank

Water storage tanks offer a range of uses in residential, commercial, and industrial applications. A water tank can be used in any situation that calls for water storage.

Below are the most common uses of water tanks:

  • Household water storage
  • Agriculture
  • Fire suppression
  • Commercial beverage and food preparation
  • Industrial manufacturing
  • Irrigation

Generally, the tank’s materials, size, and specs will be tailored to fit its intended use and water requirements. 

4 Water Tank Materials

Depending on their use, water tanks may have different materials, each having its own pros and cons. The following are the most common materials found in water tanks:

1. Plastic

Plastic water tanks are durable and light. Typically made from polyethylene, plastic water tanks are long-lasting and resistant to sunlight exposure. Plastic is also the cheapest material type since it’s the easiest to construct into a water tank. 

Unfortunately, plastic tanks tend to release toxins as the material wears down. This is particularly harmful if you use it for your drinking or irrigation. Even new plastic water tanks are considered unhealthy for drinking and cooking purposes, especially when water is stored for a long time. 

2. Concrete

Concrete is another traditional material used in water tanks. Concrete water tanks are heavy and sturdy and can be installed either below or above ground. Concrete water tanks also have a thermal mass that keeps the water temperature stable during extreme outdoor temperatures. 

That said, concrete is porous, so they are often lined with plastic to prevent water from leaking out. Also, concrete tanks often leach lime, increasing water pH and creates a distinct taste. 

3. Stainless Steel 

Stainless steel water tanks are more durable than plastic and concrete water tanks. It has high resistance to chemical contamination and corrosion. Plus, it can also survive in high pressure, so there’s no risk of rusting, cracking, or freezing. 

Furthermore, stainless steel water tanks are not prone to oxidation by water and other biocides. Thus, it assures pure and safe water, unlike plastic and concrete water tanks. 

That said, while stainless steel on its own is durable, how it has been manufactured can reduce its lifespan. Incorrect welding during manufacturing and even installation can neutralize the protective element in stainless steel, allowing corrosion and rust to occur. Plus, it also reduces its longevity and durability. 

4. Fiberglass

Fiberglass is considered one of the best types of material for a water tank. It is known for its long lifespan and is generally used for storing drinking water. Fiberglass water tanks are rigid and stiff, making them relatively thin and lightweight. This makes it ideal for transporting and is great at managing water pressure. Plus, it can withstand highly aggressive weather and has high corrosion resistance. 

That said, because of its thin outer layer, more light passes through and can promote the growth of algae. Also, fiberglass water tanks may not be as durable as stainless steel tanks due to their rigidity. 


We can’t live without water. And having a dependable water tank can help you meet the daily water demand of your household. Installing a water tank is a financially wise investment, ensuring a stable water supply all year round for your family. We truly hope that this article has given you basic knowledge about water tanks to make well-informed decisions.
