Reducing your business's overall water consumption is one of the most effective ways to keep utility bills and running costs down, and is also an environmentally conscious move in a country that frequently falls victim to persistent droughts and water shortages. Consequently, more and more commercial and industrial buildings are being fitted with rainwater collection systems, with the collected water being used for everything from flushing toilets to cooling industrial machinery.

However, a rainwater collection system is pretty useless without one or more tanks to store the collected water in, and the material your tank is made from can dramatically affect how it performs, particularly over the long term. While concrete and plastic water tanks are more commonly used (especially in residential properties), many businesses that use rainwater collection systems are investing in stainless steel tanks. This unique metal is ideal for rainwater tanks, and offers a number of advantages over other potential tank materials:


Stainless steel water tanks are immensely durable and generally come away from heavy impacts and other accidental damage with little more than a minor dent. They are extremely difficult to pierce, especially if the tank is a high-capacity model with thicker steel walls, and do not have a tendency to crack when damaged (unlike concrete and plastic tanks). As such, you do not need to worry about leaks causing damage to your business premises.


Stainless steel is also immensely strong, and a stainless steel tank can hold immense quantities of water without buckling or bulging. This makes stainless steel ideal for constructing large, high-capacity collection tanks, and can save valuable space that would ordinarily be taken up by multiple, smaller tanks.


Stainless steel is famous for its immunity to rust, and a stainless steel water tank can last for decades with minimal maintenance while maintaining its strength and structural integrity. This rust resistance also means your tanks do not require rustproof internal liners, which can add to the cost of tanks made from other metals and may alter the taste of rainwater collected for potable purposes.

Easy maintenance

Stainless steel tanks are very simple to maintain, and their smooth internal and external surfaces make them particularly easy to keep clean. This is a particularly useful quality if you are collecting unfiltered rainwater, which can contain algae and other organic contaminants that can be very difficult to remove and neutralise.


While concrete tanks are practically impossible to recycle, and tanks made of plastic or conventional steel tend to degrade too quickly to recycle effectively, a stainless steel tank can be recycled easily. In many cases, the value of the metal they are made from means that scrap metal recyclers will pay you to take the tank off your hands, so a stainless steel tank is definitely the best option if you only intend to operate your business from a building for a limited time.
