Rainwater tanks are available in a wide range of sizes and materials. So which material is best. Well it all depends on what you need your water tank transport for. Where you plan to install your tank, how much water capacity you need and your geographic location all play a part in what material you should look for in a rainwater tank.
Here are some of the options available when it comes to rainwater tanks:
Concrete – Concrete tanks are most likely used in beneath ground tank installations. A concrete unit has a long life, it is one of the most durable materials. Water is kept cooler and in effect less susceptible to algae or other bacterial growth. A concrete tank is strong enough to be held underground beneath a driveway, pergola or shed.
Polyethylene – Also known as poly, or poly plastic. These are one of the most popular choices of rainwater tanks. They are light weight, cheaper to produce than other tanks and easy to transport and install. They can be used above or below ground. They do not have the same strength and durability as a concrete one.
Fibreglass- A very durable material which is suited to above ground installation. Fibreglass won’t rust or be corrupted by chemicals. While it is very durable at the same time it does not have the same strength as other materials. A fiberglass tank will be more costly than other options.
Metal – these tanks are made of steel which is usually carbon lined. Colourbond rainwater tanks are also available and can look great if you have a roof or fence in the same material. Metal tanks are surprisingly light and also quite strong. truck transport and installing these tanks is easier than with other materials. Metal tanks are best suited to above ground installations.
The material that you choose will effect the longevity of your tank. There are many factors to consider, for instance if you live close to the ocean you do not want to choose a material prone to rust. Those in urban areas may be limited by space as to the kind of tank that they can install. Those in new homes may need to have a below ground tank installed, which again will dictate the materials used.
When deciding on what rainwater tank to install at your home, think about what will suit your property and lifestyle best, not just what promises to last the longest or look the best. By focusing on your needs you will be assured to get the best rainwater tank to suit you.
