Guide to Different Types of Liquid Storage Tanks

Liquid storage tanks are an important part of everyday life, even if we don’t always notice them. They help store water, fuel, chemicals, and other liquids in homes, farms, businesses, and factories. These tanks come in different shapes, sizes, and materials—each designed for a specific purpose.

In this guide, we’ll walk you through the most common types of liquid storage tanks, how they are used, and how to choose the right one. We’ll also talk about GRP Water Tanks and Commercial Rainwater Tanks, two popular options used by many people and businesses today.

Why Liquid Storage Tanks Matter

Storage tanks help in many ways. They ensure we have clean water when needed, help us collect rainwater, and safely store fuels or chemicals. Without these tanks, it would be harder to manage water during dry seasons or emergencies.

Some reasons to use liquid storage tanks include:

• Storing drinking water

• Collecting rainwater for gardens or toilets

• Storing diesel or fuel for machines or generators

• Holding chemicals safely in industrial areas

• Providing backup supply during water shortages

Now let’s look at the main types of tanks available.

Types of Liquid Storage Tanks and Their Uses

Understanding the different types of liquid storage tanks can help you choose the right one for your needs. Below is a quick breakdown of the most common options, including their features, advantages, and best-use scenarios.

1. Plastic Water Tanks

Plastic water tanks are very common, especially in homes and small farms. These tanks are made from strong polyethylene and are used to store clean water. They’re lightweight, low-cost, and come in many shapes—round, slimline, and square.

Pros:

• Easy to install and move

• Rust-proof and UV-resistant

• Available in many sizes

Best for: Households, small gardens, or areas with limited space.

2. GRP Water Tanks

GRP water tanks are made from glass-reinforced plastic. They are strong, durable, and lightweight. GRP tanks are perfect for storing clean water in commercial buildings like offices, hotels, hospitals, and schools.

Pros:

• Corrosion-resistant (won’t rust)

• Long-lasting and easy to clean

• Hygienic – ideal for drinking water

• Strong yet lightweight

Best for: Clean water storage in commercial and industrial settings, and places where hygiene is important.

These tanks are often used indoors or outdoors and can handle extreme temperatures. Many businesses choose GRP Water Tanks because they offer both strength and safety.

3. Steel Tanks

Steel tanks are known for their toughness. These tanks can be used to store water, fuel, or chemicals. They are heavy-duty and often used on farms, mining sites, and factories.

Pros:

• Very strong and secure

• Can hold large volumes of liquid

• Good for both above-ground and underground use

Best for: Industrial use, fuel storage, or places where tanks may get knocked or damaged.

However, steel tanks may need special coatings to prevent rust and corrosion, especially if used for storing water.

4. Concrete Tanks

Concrete tanks are solid and usually installed underground. They are used for long-term water storage and can last for many years. These tanks are great for people who want a permanent solution that’s out of sight.

Pros:

• Strong and durable

• Great for underground use

• Can handle high water pressure

Best for: Long-term water storage, stormwater management, or large-scale projects.

One downside is that concrete tanks are heavy and more expensive to install compared to other types.

5. Commercial Rainwater Tanks

Commercial Rainwater Tanks are used to collect and store rainwater on a large scale. Businesses, schools, factories, and farms use these tanks to reduce their dependence on mains water. They’re perfect for irrigation, flushing toilets, cleaning, or even cooling systems.

Pros:

• Helps save water and reduce water bills

• Can hold thousands of litres of rainwater

• Strong materials like GRP, plastic, or steel

• Great for eco-friendly businesses

Best for: Commercial properties, farms, schools, and factories wanting to harvest and reuse rainwater.

Commercial rainwater tanks can also be part of a full water management system that includes filters, pumps, and overflow outlets.

6. Fibreglass Tanks

Fibreglass tanks are another strong and lightweight option. These tanks are corrosion-resistant and are often used in industrial settings to store chemicals or saltwater.

Pros:

• Strong and weather-resistant

• Long lifespan

• Can handle harsh chemicals

Best for: Chemical storage, marine use, or salty environments.

How to Choose the Right Tank

Here are a few things to think about before buying a storage tank:

1. What will you store? – Water, fuel, or chemicals?

2. How much space do you have? – Slimline or underground tanks may be better for small areas.

3. How much liquid do you need to store? – Tank sizes range from a few hundred litres to tens of thousands.

4. Where will you install it? – Indoors, outdoors, above or below ground?

5. What material suits your needs best? – Plastic, GRP, steel, or concrete?

Making the right choice depends on your specific needs, budget, and usage.

Final Thoughts

Liquid storage tanks are essential for both homes and businesses. From storing drinking water to collecting rainwater or holding fuel and chemicals, the right tank can help save money, reduce waste, and improve efficiency.

GRP Water Tanks are a smart, modern solution for clean water storage — strong, lightweight, and perfect for both homes and large buildings. Commercial rainwater tanks help businesses go green by collecting and reusing rainwater on a big scale.

Choosing the right tank means you’ll have a safe, reliable way to manage your water or liquid needs — today and for years to come.
