Poly water tanks are more than just water storage tanks – they are truly poly-functional when it comes to helping you cut costs. Many Australians are catching on to their benefits over steel for water storage. Here’s why they’re becoming so popular in the cities as well as in rural areas.
They are tougher than steel. Poly tanks are built to last long, so it’s likely that you won’t have to spend hundreds of dollars on maintenance during your tank’s long lifetime. Traditional steel tanks are weak relatives compared to these tanks made of polyethylene. Old steel tanks develop rust almost invariably like a pond growing algae. On the other hand poly tanks are so strong they can be used to store corrosive liquids like sulphuric acids and vinegar in industrial settings.
While some people claim that poly tanks are weakened by sunlight, there are plenty of UV-stabilized tanks available today to take care of that issue at the root.
You can bash them with a baseball bat. Well, perhaps not. But the point is that poly tanks are highly resistant to impact. Poly tanks are also elastic – they can expand like balloons with excess water pressure, which stops them from developing cracks. This gives them an edge over steel tanks, which are not as elastic, and develop cracks over time.
There are plenty of sizes available. You can find poly tanks to suit almost any kind of water storage requirement. You can store anywhere between a hundred litres to more than 45,000 litres in poly tanks. Of course if you live in rainy Sydney you may need a large tank, while in Melbourne, you could do with a small one. You can save hundreds of dollars in a year simply by using the rainwater you’ve harvested rather than drawing from your municipal supply.
