A Guide to Choosing Between The Different Water Tank Types

Which type of water storage tank is right for you?

When it comes to selecting between the different types of water tanks for your needs, understanding the characteristics and advantages of each type is essential. Here, we'll explore various water tank types, their specific features, benefits, and ideal applications.

1. Plastic tanks

Plastic tanks, particularly those made of polyethene, are popular due to their versatility, affordability, and ease of installation. These are types of water tanks for homes and come in various shapes and sizes to accommodate different storage capacities. Some key characteristics, advantages, and ideal usages of plastic tanks include:

• Lightweight and easy to install

• Resistant to corrosion and rust

• Low maintenance requirements

• Available in various sizes and shapes

• Ideal for both above-ground and underground installation

a)  Polyethylene tanks

Polyethene tanks are lightweight yet durable, making them resistant to corrosion and rust. They are also UV-stabilised, ensuring longevity even when exposed to sunlight. Polyethene tanks are suitable for both above-ground and underground installations, making them an excellent choice for residential, agricultural, and small-scale commercial applications. These are types of water tanks, commonly used for rainwater harvesting, irrigation, and water storage in areas where portability and flexibility are important.

2. Concrete tanks

Concrete tanks are renowned for their strength and durability. These tanks are typically constructed on-site using reinforced concrete, providing a solid and long-lasting storage solution. They are commonly used for large-scale commercial or industrial applications, including water storage for agriculture, firefighting, and municipal use.

Here are some key characteristics and advantages of concrete tanks:

• Longevity and durability, with a lifespan of several decades

• Excellent fire resistance and stability

• Can be customised to fit specific dimensions

• Provide insulation against temperature changes

• Ideal for large-scale commercial or industrial water storage

3. Steel tanks

Steel tanks are known for their strength, reliability, and versatility. They can be constructed using different steel materials and techniques, each with its own set of characteristics. Let's explore some different types of water tanks made of steel:

a) Carbon welded steel tanks

Carbon welded steel tanks are fabricated by welding steel plates together. They are highly durable, resistant to corrosion, and can be customised to suit specific storage requirements. They offer versatility in size and shape, accommodating various storage capacities. Carbon welded steel tanks find extensive use in storing potable water, wastewater, chemicals, and petroleum products, ensuring safe and reliable containment. 

b) Bolted steel tanks

Bolted steel tanks are constructed by bolting together prefabricated steel panels. They offer flexibility in terms of size and can be easily expanded or relocated. These tanks are heavy-duty and capable of handling substantial capacities, making them suitable for demanding industrial or commercial applications. They are often used for commercial and industrial water storage needs, including rainwater harvesting, wastewater treatment, and potable water storag.

c) Corrugated steel tanks

Corrugated steel tanks are made of galvanised steel panels with a corrugated design. They provide structural strength, and resistance to external forces, and are suitable for above-ground installations. Corrugated steel tanks are commonly used for agricultural purposes, such as livestock watering and irrigation, as well as for fire protection systems.

d) Stainless steel water storage tanks

Stainless steel tanks offer exceptional durability and corrosion resistance. They find extensive use in storing potable water, food and beverage products, pharmaceuticals, chemicals, and various liquids requiring a high level of sanitation. Additionally, stainless steel tanks are well-suited for aggressive environments, such as marine applications or wastewater treatment facilities. Their ability to maintain water quality, resist external forces, and ensure long-term reliability makes them a great choice for industries demanding high-quality storage solutions.

4. Fibreglass tanks

Fibreglass tanks are lightweight, yet strong and durable. They are constructed using layers of fibreglass and resin, providing excellent resistance to corrosion and chemical damage. Here are two common types of water tanks made of fibreglass:

a) Underground fibreglass tanks

Underground fibreglass tanks are engineered for discreet water storage beneath the surface, offering unobtrusive solutions. With exceptional non-corrosive properties and resistance to soil chemicals, they ensure long-lasting durability and water quality maintenance. Ideal for residential, commercial, and agricultural needs, these tanks excel in rainwater harvesting, irrigation, and septic systems, catering to sustainable water practices.

b) Above ground fibreglass storage tanks

Above-ground fibreglass tanks provide unmatched versatility, easily tailored to specific requirements. Their lightweight construction facilitates effortless installation and transportation. These tanks find extensive use in industrial processes, chemical storage, and water treatment applications, emphasising reliability and structural integrity. The superior corrosion resistance and ability to withstand diverse weather conditions make them a preferred choice for above-ground storage needs, ensuring optimal protection for valuable contents.
