Water tanks are essential for storing and supplying water for various purposes. However, these tanks can develop leaks, rust, and other issues over time, compromising their integrity. When faced with such problems, homeowners and business owners have two options: water tank lining or replacement.

In this blog, we will explore the pros and cons of each option to help you make an informed decision.

Water Tank Lining

Water tank lining is the process of applying a protective coating to the interior of the tank to prevent leaks and corrosion. The lining can be made of various materials, including epoxy, polyurethane, and fiberglass. Here are some of the advantages and disadvantages of water tank lining.


1. Cost-Effective

Water tank lining is generally much cheaper than replacing the entire tank. The cost of lining depends on the size of the tank, the type of lining material used, and the tank’s condition.

2. Quick Turnaround Time

Water tank lining can be completed in a matter of days, depending on the tank size and the lining process’s complexity. This means that you can have your tank back in operation quickly.

3. Minimal Disruption

Since water tank lining is done on the interior of the tank, there is minimal disruption to the surrounding area. This is especially important for business owners who cannot afford to shut down their operations for an extended period.


1. Not Suitable for All Tanks

Water tank lining is not suitable for all types of tanks. For example, if the tank is structurally unsound or has extensive rust damage, lining may not be a viable option.

2. Limited Lifespan

While water tank lining can extend the life of your tank, it is not a permanent solution. Over time, the lining material may deteriorate and require replacement.

3. Preparation Is Crucial

To ensure that the lining material adheres properly to the tank’s interior, the surface must be cleaned and prepared thoroughly. This can be a time-consuming and labour-intensive process.

Water Tank Replacement

Water tank replacement involves removing the old tank and installing a new one. This option is usually recommended when the tank is beyond repair or when a larger or more durable tank is needed. Here are some of the advantages and disadvantages of water tank replacement.


1. Long Lifespan

A new water tank can last for many years, depending on the type of material used and the quality of installation. This means you won’t have to worry about leaks or other issues for long.

2. Customizable

When replacing your water tank, you can choose a tank that suits your specific needs. This includes tanks of different sizes, materials, and shapes.

3. Warranty

Most new water tanks have a warranty covering manufacturing defects and other issues. This provides peace of mind and protects you from unexpected repair costs.


1. Expensive

Water tank replacement is generally much more expensive than water tank lining. The replacement cost depends on the tank’s size, the type of material used, and the complexity of the installation process.

2. Time-Consuming

Water tank replacement can take several days or even weeks, depending on the tank’s size and the installation process’s complexity. This means you will be without a water supply for an extended period.

3. Disruptive

Water tank replacement can be disruptive to your home or business operations. This is especially true if the tank is located in a hard-to-reach area or if the replacement process requires significant excavation or other disruptive activities.


Both water tank lining and water tank replacement have their advantages and disadvantages. The choice between the two options depends on various factors, including the condition of the tank, the size of the tank, and the budget available. 

If your tank is in good condition and only requires minor repairs, water tank lining may be a cost-effective solution. However, if the tank is beyond repair or needs a larger or more durable tank, water tank replacement may be the better option. Whatever your choice, it is essential to work with a reputable and experienced water tank specialist to ensure the best possible outcome.
