Water storage tanks are a frequent requirement for storing potable water (and even rainwater) for everyday use. With water scarcity issues becoming more prevalent with each passing year, having a storage option for any form of residential or business structure is essential. 

Furthermore, with the Department of Irrigation and Drainage in Malaysia emphasizing rainwater harvesting, the demand for a water storage tank on one's property has grown. The recent water supply interruption in Selangor is proof of this. 

All things considered, it's crucial to remember that not all water tanks are created and used in the same way. Choosing the correct water tank is therefore difficult because there are numerous aspects to consider.

This post will explain the distinctions between several types of water tanks and assist you in selecting the one that best meets your needs. Let's take a look at five of the most typical water tanks in Malaysia.

#1 FRP/GRP Sectional Water Tank

Glass Reinforced Plastics (GRP) Water Tanks are also known as Fiberglass Reinforced Plastic (FRP) Sectional Panel Water Tanks. These are manufactured from a combination of resins, glass fibers, and hardeners. The interior surface of these water tanks is normally coated with a food-grade coating, making the material safe to keep drinking water. 

They are one of the greatest solutions for storing drinking water because of their non-cytotoxic coating. Overall, FRP/GRP Sectional Water Tanks are cost-effective, customizable, versatile, and durable, with a long lifespan. As a result, they're perfect for industrial, commercial, and residential applications.

#2 Pressed Steel Sectional Water Tank

Pressed Steel Sectional Water Tank is made of pressed steel (Q235 Pressed Steel) and has a thick zinc alloy coating on the outside. A zinc coating is applied to the interior surface of the tank to prevent rust and corrosion. This makes the tanks extremely long-lasting, with a minimum lifespan of ten years.

Depending on the thickness of the coating required, a variety of panel sizes are available. The cost of the tanks varies based on their size and coating thickness. A more expensive price will be associated with a thicker layer of coating.

An inner food-grade polyethylene lining is often included with a Pressed Steel Sectional Water Tank to provide further protection against rust and corrosion caused by the water kept inside. The inner lining also prevents zinc from leaking into the water, which could give a metallic taste to your drinking water.

#3 Polyethylene (Plastic) Water Tanks

Polyethylene tanks are low-cost, high-capacity water storage tanks that can be used for both household and industrial applications. Non-toxic, high-density linear polyethylene is typically used to make them. These tanks are also made of food-grade plastic that has been UV treated. 

This makes them durable and resistant to chemical attacks, temperature changes, inclement weather, and even UV rays. Even though the tanks are composed of polyethylene, they are opaque. As a result, they do not allow sunlight to pass through, making them an excellent choice for reducing algae development on the tank walls. 

#4 Stainless Steel Water Tanks

These tanks, as you might expect, are built of stainless steel plates, which give the construction a lot of strength. The stainless steel material has stable physical and chemical qualities, does not affect water quality, and provides safe and sanitary drinking water.

High strength, lightweight, clean look, gorgeous appearance, and elegance are all features of the water tank. Steel's texture is firm and polished, easy to clean, and attractive to the eye.

The material is corrosion-resistant and high-temperature resistant, making it ideal for use in the factory, houses, schools, hospitals, restaurants, and dobby, as well as major hotels, institutions, flats, research and teaching structures, and the food, medical, and health industries.

#5 Concrete Water Tanks

Concrete tanks are a common alternative for both above and below-ground applications. Steel reinforcement is used in most tanks to add strength to the structure. Concrete tanks are divided into two categories:

1. Concrete tanks that have already been built
2. Concrete tanks were constructed on-site
