A water tank is a long-term investment. Ideally, you would want to just buy one. However, like any other investment, you’ll want to know how long a water tank will last. When it comes to water tanks, how long one lasts will depend on several factors. This includes the material used to make the tank, the usage, and the location of the tank. According to Water Online, there are storage tanks that are still in use that are 100 years old! Here’s what you may want to know to extend the service life of your tanks.


The majority of water tanks are either made using plastic or metal. You’ll find that plastic tanks are a lot less expensive than metal ones. However, these require less maintenance. Plastic water tanks are usually made using UV-stabilized polymer and are non-biodegradable. This simply means that they should not break down over time. In general, a plastic water tank should serve you for up to 20 years. Metal water tanks are quite strong and durable, as you would expect, and have a life expectancy of more than 30 years.


Where your water tank is located is another factor that contributes to life expectancy. One of the issues you have to consider when you have a metal water tank is rust. This means you need to avoid areas where the water tank will be exposed to wind or salt water. This can be a problem if you live near the sea. The best way to preserve your metal water tank if you live near salt water is to add sheeting on the outside. You can also apply a treatment to help protect the tank. You must also think about where the tank is placed. Water tanks can be damaged by standing water, so you should try to ensure that the tank is on a solid surface. When dealing with plastic water tanks, you should try to avoid too much exposure to direct sunlight, as UV treatment can be affected if the tank is in arid areas.

Tank Use

You can use water tanks for several things. However, the general rule of thumb is that tanks generally last for longer with clean and pure water. Tanks with salt water will generally not last long because they’re more prone to corrosion. If you have tanks that you use for drinking water, you must put a liner in them. This is a great way to extend the service life of your tanks. A liner will not only protect the tank but will also stop oxidized zinc from ending up in the water. If you have a plastic water tank that you can use for portable water, there’s no need to use lining since it’s already made using food-safe material.

Water tanks last considerably longer if you take good care of them. It’s important to figure out what needs to be done to extend the service life of your tanks. Get in touch with us if you need more tips for maintaining your water tank.
