Steel Liner Tanks vs Concrete Tanks for Fire, Potable and Raw Water

Steel Liner Tanks vs Concrete Tanks for Fire, Potable and Raw Water

Climate change poses a massive threat to water security, with the occurrence of droughts likely to continue to rise. The importance of reliable water tanks is therefore paramount. The climate council predicts that rainfall in Australia will decline further, potentially by 50 percent throughout the next 80 years. The question of how to reliably store water is an age-old one, whether in reservoirs for fire-fighting, or storage containers for potable and raw water. Whether to provide a complete water supply or to supplement an existing one, the question remains: what material should be used to offer a long-term, sustainable water supply?

Benefits of Using Concrete Tanks

Concrete or cast in-situ tanks have been proven for over 100 years to keep water cool and free from algae and disease. They offer a range of uses and can be placed underground, providing stable water temperatures and naturally reducing rainwater acidity.

Disadvantages of Concrete Tanks

Installation:

Concrete tanks of over 5,000 gallons (a relativity small tank) must be built on-site, where heavy work is required. Concrete must be supplied to the site or mixed there. Poor site access can impede construction, which is also weather dependent. There are safety concerns: installation of the tank roof requires a great deal of scaffold as ladder heights would exceed Australian Standards. Site costs, transport of materials, labour and accommodation for workers all add up to expensive construction costs, project delays, and negative impacts on the environment.

Maintenance:

Concrete tanks can be damaged by vibration from nearby traffic or ground movement. They have a tendency to crack, allowing water to gain access to the steel reinforcement.

Disposal:

Concrete is non-recyclable. This is due to variation in concrete quality, which causes uncertainty in the strength of recycled concrete structures.

Advantages of steel panel liner tanks

Installation:

Steel lined tanks pack down to manageable sizes, making transport easy. Tanks can be constructed in a circular or square shape, with endless configurations to suit site restrictions. Assembly is quick and easy with the jacking system, which allows installation to build upwards. This makes it a viable system for remote sites or small spaces where the storage container is required inside. Ladders are supplied to relevant Australian standards, meaning no need for a scaffold. All this saves hassle and expense.

Maintenance:

These tanks require minimum maintenance for long-lasting service. They are constructed from steel, which is considered to be a safe material even for drink bottles, catering and surgical equipment. Our liners are made from high-grade PVC material, resulting in a soft, world-class product. The tanks can be installed with an air vent to keep air moving in the roof void, and side wall access hatches for ease of maintenance.

Disposal:

Steel is 100% recyclable.

The steel liner panel tank was engineered and manufactured for ease of transport, delivery and assembly. For this reason, the steel panel liner tank is the firm favourite in the rural community around Australia and in commercial industries around the world.
