Is Plastic Water Tank Safe?

Plastic water tank is a rapid progress making product which are made of impact-modified, UV- treated, food grade polyethylene. This refers to the fact that they are long-lasting, durable and appropriate for reserving  potable or quality drinking water.

The most commonly used plastic resin, polyethylene is a applied and real plastic that will not crash down in the sun for minimum 25 years. This very reason supports why plastic water tanks exist.

As one of the few specialities of plastic water tank is that they last for a long period of time such as upto 20 years or more. These water tanks are rotary moulded.

As a result, they can withstand the severe effects of the sun because of the UV-stabilisers which are put to the moulding mix.


A plastic water tank is an enormous capacity liquid that is designed to store different gallons of various substances for an extended period of time without experiencing weathering,  deterioration and erode. Plastic tanks work as a means of saving and shifting materials for later use by farmers, manufacturers and fuel companies.

These huge water storage units can be vertical, horizontal, above or below the ground and they can portable as well. Although the shapes and sizes vary according to the producer but from an engineer's point of view the potent profile design is very much corrugated. As such designs represent the look of a conventional tank, they can be used for a positive selling point.

Generally polyethylene and polypropylene work as the common raw materials for the making of plastic water tanks.  Plastic water tanks are found in a range of colors and they are comparatively light-weight. Hence it makes them  easier to install and transit.

The tank walls can range from. 20 inches thick to 1.5 inches thick , varying on its geometry. Plastic water tanks are corrosion resistant and offer inexpensive options while purchasing.

Kinds of Plastic Water Tanks

Plastic Water Tank

Classification of plastic tanks vary depending on the materials that are used for making them, their usage as to which ones are produced for storing solid and grains and which are produced for fuel and chemical applications.

An another method of classifying is on the basis of how they are positioned. Let us know the classification of plastic water tanks on basis of their placements.


These plastic tanks are resistant to corrosion, rust, specific chemicals and UV rays. They are ideal for use in liquid storage facilities, mixing plants, pharmaceutical industry because of their stability and strength.

Double Wall

They are structured in such a way that a tank is placed within another tank in order to provide  secondary containment for contents. They are made to work as a safety measure and for meeting environmental protection standards against perilous chemical spills.


They are specialized tanks that have stands so that the contents can be obtained from their cone shaped neb at the bottom of the tank.


These are the most commonly found form of tanks as they are used for general purposes and are more ductile and easier to access. They are placed in an underground chamber of brick or concrete since they limited to above ground applications.


They are lighter than other form of tanks which makes them easier to place, relocate and transport. They are used for both underground and above ground applications since they are corrosion resistant, viable and do not deteriorate.

Usage of Plastic Water Tanks

Plastic Water Tank uses

Primarily plastic tanks were used to store water for crops, livestock and irrigation. Along with time,  plastic water tanks were used for other purposes. Starting from the storage of all forms of water like ground water, salt water, distilled water and so on to storing fertilisers, pesticides and other forms of acid like nitric acid, hydrochloric acid etc can be preserved. They are also used to store fuel, grain like materials such as corn, soyabeans.

Points to note

Apart from the fact that plastic water tanks last for 20 years or more it should be noted that plastic will be ruined for the sun's radiation with UV- rays.  And as such they may not be of use for 15 to 20 years. And as to answer of the very question ‘ Is plastic water tank safe? ‘.

They are 100% safe for reserving drinking water since they are manufactured from food-grade safe , BPA-free polyethylene plastic. This is what a certain research says. However scientists have said BPA- free plastic products can be as harmful as to destroy a developing human brain.

To wrap it all up

Plastic water tanks are recently risen in popularity because of affordable and flexible they are. With opportunities in residential, commercial, industrial sectors the future of plastic water storage tanks market look promising. Remember to choose a plastic water tank or any other tank on basis of your needs and property.
