Making the decision to have a rain water tank installed on a property is an exciting one, but this isn’t the only choice that people will be required to make when they take this step. These days, there are a range of materials that can be used in the construction of rain water tanks, including polyethylene and cement, and it’s up to each buyer to decide which one suits their needs best.
The Pros and Cons of the Poly Tank
Poly (polyethylene) tanks, the same products that are made by Quality Tanks, are manufactured from the same substance that people throughout the world have become very familiar with – plastic – although it is considered to be the safer form of this material. Since these tanks are going to be exposed to the elements, including the sun (which is now known to have disastrous effects on plastic), the material is equipped with UV stabilisers so that the plastic doesn’t end up breaking down on the outside.
These specific types of tanks usually don’t have as high a shelf life as the concrete options, for instance, although they do tend to be the more cost effective option out of all of them. It should also be noted that within Australia, because of the UV degradation that occurs over the course of time, people might not have the option to recycle the tank when it has exceeded its shelf life.
Due to the easy nature of the installation, these tanks can be installed very quickly, as long as it is placed on a flat area of ground. The manner in which the material moves makes it a more flexible option during installation, and individuals shouldn’t have a hard time finding tanks in a range of shapes and sizes to fit in just about any space.
The Pros and Cons of Concrete Water Tanks
When it comes to installing in a rainwater tank, individuals have another option available to them; concrete. These tanks tend to be cast on an off-site location and then transported to your property for installation.
Water tanks manufactured from concrete generally have a steel reinforcement, although the material itself is generally made from a combination of sand, lime, gravel and water. In terms of water quality levels, many people are turning to alternatives to polyethylene simply because concrete is more natural, as well as the fact that it is able to keep the water temperature a lot more stable. Basically, by keeping stable temperature levels and preventing hot spots from occurring within the tank, this material is actually able to prevent algal blooms.
Concrete tanks tend to be a bit more expensive than poly tanks, although they do end up lasting a lot longer and so many people consider this to be worth the added expense. In terms of setting up the tank, concrete tanks are able to be installed above ground, partically buried or fully buried underground, which means you won’t see them taking up valuable space on your property. In terms of recyclability, concrete gives you extended life span meaning that people won’t have to worry about replacing the tank for years to come.
Ultimately, understanding the pros and cons of poly vs. cement rainwater tanks can go a long way in helping individuals make a decision concerning the best option for them. Keep in mind that in some instances, this choice will rely greatly on a person’s unique circumstances and so it is sometimes worthwhile contacting the professionals to ask them for some advice on the matter.
