The water stored in water storage tanks is used for various purposes. Therefore, there should not be any compromise with the quality of the water tank as it may directly affect our family’s health. In general, plastic water tanks are mostly preferred for all domestic purposes, especially in India. On the other hand, steel water storage tanks are also a popular choice amongst many people for domestic use. Before choosing among the two, we should know the difference between them –

Easy installation

A firm foundation is very important for a plastic tank as well as for steel tanks. However, the foundation required for steel tanks has to be more firm than plastic tanks. We should also see if the foundation is protected from erosion or not. Once the tank is installed nobody would like to move it again until and unless it is really necessary. Steel tanks are heavy and hence it is difficult to move, once installed. It might develop cracks on its surface, whereas a plastic water tank is comparatively easy to relocate owing to its lightweight.

Corrosion Resistant

Steel tanks are prone to corrosion with continuous use in the long run. Although good quality stainless steel can run for a longer time without getting corroded. However, it will at a later date. Steel tanks should be kept away from chlorine and salty seawater. On the other hand, we know that plastic cannot rust simply because it does not contain any iron and is non-metallic.

UV Stabilized

Steel water tanks do not protect the water from the growth of algae as they are not UV-stabilized. On the other hand, good quality plastic water tanks in India have the capacity to withstand the harsh effects of the ultraviolet rays of the sun, especially during the summer season due to UV stabilizers present in the molding mix while manufacturing them.

Size

The capacity of a steel tank is much more than a poly tank. A steel tank can hold up to 2, 50,000 liters of water whereas a poly tank can hold up to only 50,000 liters of water. Poly tanks are mainly used for household purposes so a capacity of 50000 liters is enough to serve the purpose.

Maintenance

Taking care of a steel tank is much more difficult than maintaining a poly tank in both the short and long run. Steel tanks have to be wiped and washed with freshwater very frequently to protect it from rust. On the other hand, poly tanks have a self-cleaning system that keeps the inner tank clean. It is also less expensive to maintain a poly tank over a steel tank.

Therefore, it is highly recommended to use the best quality plastic water tank over steel tanks as the former has many advantages over the latter.
