Comparison: Plastic Water Tank vs. Concrete Water Tank

plastic tank vs concrete water tank

Plastic and concrete storage tanks are often used to store drinking water. When it comes to choosing between plastic and concrete, you should know more about the fundamental distinctions with the help of water tank manufacturers.

With that in mind, below, we’ll go through the pros and cons of both plastic and concrete water storage tanks to help you make an informed choice.

Pros of Plastic Tanks

  • Sturdy 

Plastic tanks are made of sturdy material, perfect for harsh weather conditions. 

  • Durable

As the tanks are made of good quality plastic, they are highly durable and are built to last.

  • Non-corrosive

Plastic storage water tanks contain no seams, beams, or sealed components since they are molded from a single piece of plastic. Additionally, they are impervious to water-based damage. Besides, plastic tanks are resistant to corrosion and rust, whether positioned in moist soil or above ground in a humid area. 

  • UV Stabilized 

Plastic Tanks are specifically UV stabilized, making them perfect to be kept outside in the open conditions. 

  • Easy to see water inside 

Plastic tanks are blue from the inside, to maintain easy visibility. This coating makes it easy to see the water level. Built in a way that allows you to gauge the tank’s water level by looking inside the tank, Sheetal’s water tank checks all the right boxes for domestic & industrial use.

  • Easy maintenance 

Plastic water tanks are much easier to maintain than concrete ones since they are lighter and don’t need heavy gear to lift and carry them. In isolated places where transportation expenses are exorbitant, they are suitable for septic treatment and water storage alternatives.

  •  Food grade safe

Drinking water should be safe and free of toxins. A food-grade safe plastic tank can help keep the drinking water safe from toxins, making these tanks perfect for drinking water. 

Cons of Plastic Tank

  • Prone to Breaking 

Under extreme pressure, plastic is more prone to breaking than concrete, which is more rigid. Above Ground plastic tanks are more susceptible to cracking than concrete under harsh weather. This is an essential consideration if your home is located in a region prone to hurricanes, tornadoes, or wildfires.

  • Less Durable 

Owners must exercise caution while loading their plastic tanks since it lacks the level of strength and durability that concrete offers.  A poly tank may be dented, warped, or crushed if overloaded. 

Pros of Concrete Tanks

  • Durability

Concrete has been used in building for hundreds of years and is very durable. Construction workers use concrete to create tanks, foundations, and other buildings that can withstand geological and environmental forces since they can be formed into almost any shape.

  • Resiliency 

Due to their resiliency, concrete tanks do not need a lot of upkeep. (However, the tank’s location and design have a big role in the complexity and frequency of repairs.) Concrete’s high thermal mass makes it an excellent choice for storing drinking water since it helps maintain consistent temperatures whether the water is kept above or below ground.

Cons of Concrete Tanks

  • Difficult to Transport 

Transporting and installing this weight is difficult, and the associated expenditures may add up quickly. The tank cannot be lifted out of the ground and sealed with a fast sealant; therefore, installers must employ heavy gear to move it to the appropriate place. 

  • Leakage Problems

Concrete deteriorates with time, making it more prone to fractures and erosion, leading to leakage. Again, these leaks are difficult to mend, particularly if the tank is located underground, and they’re not cheap. In concrete septic tanks, fractures may enable untreated sewage or wastewater to seep into the surrounding soil or even rise to the surface if they’re large enough.


Although both the plastic and concrete water storage tanks have their unique advantages and disadvantages, the former seems to be the superior option if purchased from a trustworthy water tanker supplier, ensuring both the quality and safety of your family.
