Water tanks are an essential part of many businesses, used to store clean, safe water for industrial and commercial purposes. Over time, however, the tank is exposed to various factors that can cause corrosion, leaks and potentially water contamination.

The water tank lining is one of the measures that offer protection against these faults. The lining extends the lifespan of the tank, but it also protects the contents inside, keeping it safe for use.

In this article, we’ll talk through the purpose of water tank lining systems and how you can maintain them.

What is a Water Tank Lining?

The water tank lining is a protective layer inside of the water storage tank, tailor-made to suit the dimensions of the tank. It is there to help prevent damage from internal and external factors. The lining, which can be made from butyl rubber, EPDM, or PVC materials, acts as a barrier between the contents of the tank and the shell of the tank itself.

Apart from increasing the life-expectancy of the tank, if you have drinking water in the tank, for example, it won’t become contaminated by the metal tank structure as the tank ages.  

The Benefits of Water Tank Lining

The main benefit of water tank lining systems is that they prevent corrosion. Metal tanks are especially susceptible to rust, particularly if they have been storing water for long periods of time. Proper tank lining protects the walls of the tank from direct contact with the water, which helps maintain the structural integrity of the tank and the cleanliness of the water.

Tank linings ensure:

• Fewer repairs and replacements in the long run, saving time and money
• Reduced risk of contamination from bacteria, algae and rust
• Easy repair, if the membrane is punctured it can quickly be fixed with minimal business disruption
• The water tank itself lasts longer, as reinforcing the interior can add years of functionality to the tank itself

Health and Safety Considerations

As a business, there are also certain health and safety regulations you need to be aware of. If you are storing potable or drinking water, it must be held within a container that has been tested to BS6920 standards and that is approved under the UK Water Regulations Advisory Scheme.

Other Ways to Maintain Your Business’s Water Tank

As well as tank lining, there are other ways to extend the longevity of your water tank.

• Water tank lining paint: Specialised tank lining paint is usually made from epoxy or polyurethane-based chemicals. When applied inside your tank, it can fortify the tank against chemical exposure, temperature changes and constant water contact.
• Regular inspection: You should schedule routine checks of the tank, looking for signs of corrosion, leaks or damage. Early detection can help prevent small problems from becoming major ones. You could arrange for a professional tank survey service to inspect the inside of the tank.
• Water quality: Regularly check the water’s pH level, to help prevent internal corrosion.
