The Role Of Materials In Underground Rainwater Harvesting 

The Role Of Materials In Underground Rainwater Harvesting 

Rainwater tanks are used to utilise and harvest the pouring rainwater that falls on the rooftops or hard surfaces above the ground so this could be utilized later on in the times of need specifically during the water shortages. This permaculturist approach has been gaining a lot of momentum in Australia as many Aussies have been shifting towards installing one above or under the ground with the intent to cut on water supply bills, to preserve water and to be efficient towards the environment. In addition to this, there are many other ways you can restrict the use of regular tap water by utilising the harvested rainwater as an alternative instead such as flushing toilets, during landscaping and gardening, running laundry and washing equipment, to name a few.

There are many things that one should consider before installing the rainwater harvesting tank in the premises such as the size of the property where it would be installed, would it be placed above the ground or underground, the frequency of rain in your area and the size of the roof from where rainwater would be harvested. Moreover, there’s another thing which carries utmost value in affecting your decision of placing the rainwater tank in the house which is the type of material being used.

There are different types of materials available to build the rainwater tank, each varies with respect to the consumer usage and requirements. The most common ones are as follows:

Concrete 

This type of water storage tank is very heavy and usually, is installed underground which requires excavation to the great extent in the initial stage, affecting the cost factor ultimately. This type of underground rainwater tank is expensive as compared to others and should be well planned as compared to its lightweight above the ground counterparts. Apart from that, concrete can discharge lime which would leach into the water especially if the tank is new while making the stored water alkaline. Alkaline water is not good for many plants, hence usage would be restricted. But by going with the lining coating around concrete wall could help you get rid of this problem at hand.

Metal 

Metal is an inexpensive alternative to the concrete material type of rainwater tanks in Australia and is generally placed above the ground, making it easier to install as compared to its counterparts. The metal material is prepared through galvanised steel which is soldered together in order to enable it to mould it to the different shapes and sizes, as per the clients’ requirement. The issue with the galvanised steel is that it is prone to rust. Though this type of water is not harmful to plants but the integrity of tank is undermined due to the rusting process, as a result, you might have to change it sooner than expected due to leakages and other damages.

Fiberglass 

The most commonly used and reasonable material for underground water tanks is made of fibreglass which is a densely woven string of plastics, reinforced by the glass fibers. This makes them stronger than metal counterparts and a good choice to store a huge amount of rainwater without the rust or the deteriorating material strength issues. ChemStore Group in Australia has been providing well-manufactured rainwater tanks in Australia made of finest quality fibreglass due to its many proven advantages. Their tensile strength makes them able to withstand the pressure of water without having to face any problem.

Polyethylene

It’s a cheap alternative to fibreglass, tends to be lightweight which makes it easier to transport and install in the house. However, it is subject to erosion if overexposed to the sunlight; additionally, these come in standard sizes and shapes so you cannot mould them as per your requirement or fit them in a place which is irregular.

Bladder 

It is made of a flexible membrane which can be used as an above or underground rainwater tank. It expands when rainwater enters it while contracts when the water is siphoned off. These are the perfect solutions for small and irregular spaces where water needs are limited. However, their drawback is the limited capacity of storing rainwater which does not make them a lucrative option for many to go with it.

ChemStore Group after considering the needs, location and rain frequency of area provides instant consultation to its prospects not only about the material of the object but also about the placement and integration with the regular water lines going into the house which is a huge plus and a source to answer all your popped up queries about the having or not having the rainwater tank Australia in the house.
