Stainless steel rain water tanks are a big investment, so it’s important to ensure you select the best tank for your needs. With sizes ranging from 400 litres to 34,000 litres, Stainless Steel Tanks has the right tank for everyone, from homeowners to farmers, builders and commercial business owners. Common factors to look at when considering tank size include:

  • Where will you install the rainwater tank and how much room is available?
  • Why are you installing a water tank, what will you use the water for and how much will you use?
  • How much rainfall can you expect?
  • How large is your catchment area?

Determining the appropriate size for your rainwater tank involves considering several factors such as the size of your roof catchment area, the amount of rainfall in your region, and your water usage needs.

Get in touch with our team today to assist you with calculating the appropriate tank size for you.

To provide you with a more personalised calculation, we will need some information such as:

  • The size of your roof catchment area – You can get this value by multiplying the length and width of your roof to obtain the roof area in square meters
  • The average annual rainfall in your area, which you can easily obtain from your local weather bureau or various online sources.
  • Your estimated water usage – You can determine this by assessing the number of people in your household and your daily water usage, including drinking, cooking, cleaning, and watering plants.
  • Depending on your specific situation, there may be other factors to consider, such as the cost of the tank, available space, and any local regulations regarding rainwater harvesting.

Based on the amount of rainwater you can collect and your water usage requirements, we can estimate the minimum tank size necessary. To ensure you always have a supply of water, it is recommended that your tank be able to store at least two weeks of water supply.

It is essential to note that these calculations are just estimates, and your specific circumstances may require a larger or smaller tank.
