Your space, usage, catchment surface and the rainfall in your area – these are the main considerations in choosing the best rainwater tank for your home or your business. We will guide you through these factors to help you get the most suitable tank for your needs.
Where can I install my tank?
It is important to consider where you will put a tank before you acquire one. This will then lead you to the question of how much space you have available.
If space is not an issue, you can go for round water tanks. If your space is a bit narrow, you can go for slimline water tanks. The exact size of the tank will depend on the space available and your usage needs.
What am I going to use the gathered water for?
Is this going to be your main source of water or just an additional source? If you are not on mains water, you will need a tank that is big enough to store and supply water for almost, if not all, your daily needs.
If you intend to use the stored water for drinking and cooking, make sure that you get a rainwater harvesting system made of food-grade material. Manufacturers like Rainfill Tanks and Curved Roofing Supplies provide rainwater tanks in Western Australia that are suitable for drinking water storage.
How much rainwater can I harvest?
You also have to consider how much rain you can gather when determining the size of your tank. The amount of rainwater you can harvest depends on the rainfall in your area and the size of your catchment area, your roof.
You can check with your local weather station to determine your area’s rainfall. For your roof, get an accurate reading of its size. From there, you can calculate your rain harvesting capacity by multiplying the size of your catchment area by the rate of rainfall in your locality.
Choosing the right tank may involve some measuring and math, but the work will pay off when you have a rainwater catchment system that is perfect for your needs.
