A water tank is a long-term investment. Ideally, you should buy one for the long haul. However, like any other significant purchase, it’s important to consider how long a water tank will last…

Buying a water storage tank for a home or business is a significant investment. However, as with any important decision, installing a reliable tank requires a considerable commitment.

Although there is no exact answer, understanding the factors that affect the lifespan of a water tank will help you choose the type that best meets your needs and preferences.

Materials

Most water tanks are made from either plastic or metal. Plastic tanks tend to be much more affordable than metal ones…

However, you don’t want a tank that will only last for a few years, so it’s best to avoid water storage tanks made from plastic barrels…

A polyethylene water storage tank is a great option, as it is made from UV-treated, food-grade, non-biodegradable plastic, ensuring long-lasting durability and safety.

Location

Another factor that influences life expectancy is the location of your water tank.

The geophysical characteristics of the location where you’ll install the unit also influence the water tank’s life expectancy.

Usage

Water tanks can be used for a variety of purposes. However, the general rule of thumb is that tanks last longer when filled with clean, pure water.

If you take good care of your water tanks, they will last much longer.

A tank’s service life is also determined by how it is used. A unit containing clean and fresh water for human consumption will typically have a much longer lifespan than a unit containing harsh chemicals or salt.

It is strongly advised to use a food-grade tank liner when storing potable water in a stainless steel tank.
