Traditionally steel tanks have been the first choice for water
storage, but they have limitations. For one thing, steel tanks are at the mercy
of the elements and corrosion is a common issue.
With the variety of rotomoulded
polyethylene tanks available on the market it means that you can avoid
corrosion and have a tank with a longer life. We look at 7 practical benefits
of using plastic tanks over steel tanks.
1. Plastic tanks weigh less
Steel tanks weigh a lot more than
plastic tanks and usually need the help of a crane to move them onto your
property. In comparison, plastic tanks are lightweight and can be moved into
position by hand, which is an advantage if there is hilly or rough terrain on
your property.
2. Easier to position
The surface upon which steel tanks
sit need significant preparation before the tank is installed. This can involve
expensive steel rings and a concrete base to keep the bottom from rusting.
Plastic tanks can sit on any flat surface as long as there’s nothing sharp
underneath, some can also be positioned underground away from sight.
3. A wider variety
Steel tanks are circular with a
coned roof. They may change in diameter but the basic shape is the same.
Plastic tanks on the other hand, come in a wider variety of shapes and sizes.
From rounded and slim line there is sure to be a plastic tank to suit your
needs.
4. Blend better with the landscape
Plastic tanks come in a greater
variety of colors than steel tanks. They can stand out or blend in with your
home and landscape depending on the look you’re going for. They are
suitable for both rural and urban use.
5. They won’t rust
As mentioned, the biggest advantage
of plastic tanks over steel tanks is that they don’t rust over time and need to
be replaced. Their longevity is also due to the fact that they are made to
withstand the Australian climate. UV-inhibitors protect the tanks from
degradation from sunlight.
6. Strong and durable
Steel tanks are hardy, but as their
parts are welded or bolted together, side seams, joints and weld lines can
become weakened over time. The rotomoduling process bonds plastic through speed and heat, with the use of
a mould, so the final product is more durable and less likely to fall apart.
7. Better for drinking water
Steel tanks are galvanized with a
zinc wall which, while not a health risk, can affect the taste of drinking
water. Studies on some steel tanks have also shown a harmful level of lead.
Many people are not comfortable in taking this risk with their drinking water.
Plastic tanks are manufactured from food-grade safe, BPA-free polyethylene
plastic so they’re 100% safe for storing drinking water.
