Who is a 200 000L water tank suitable for
Water tanks in the 200 000L range are a size commonly recommended for domestic household supply in rural areas outside of Australia's capital cities, and typically enough water to suit four or five people's domestic usage. The GT200 is Pioneer Water Tank's 200 000L water tank equivalent, with a gross capacity of 195,851L of rainwater storage.
For this reason, the GT200 is one of Pioneer Water Tanks most popular models, and is the first choice for many of Australians all across the country in each year, looking to ensure they have a reliable and long lasting water storage solution..
Many people purchasing a rainwater tank are rural families with no access to mains water or town water - or are simply looking to no longer rely on it - which means it is important to have enough rainwater harvesting ability and a large enough water tank size to meet your needs.
If you're looking to determine if a 200 000L steel water tank is suitable for you, you can consult our water storage calculator (below) to determine how much rainfall you can capture from your roof, and make sure to track of how much water your household is using.
The below table shows the dimensions and gross capacities of the GT200 and GT220 model water tanks.
Tank Model | Gross Capacity (Litres) | Gross Capacity (Gallons) | Diameter | Height |
---|---|---|---|---|
GT200 | 195,851 | 43,081 | 10.70 m | 2.18 |
GT 220 | 221,097 | 48,635 | 11.36 m | 2.18 |
Gross Capacity is the total tank volume not including the water loss above the overflow or below the outlet.

You Can Never Have Too Much Water
Water Catching and Usage Factors To Consider
Fire Reserve
This is a volume of water that is always readily available in the event of fighting fire. Commonly this can be up to 20,000 litres.
Irrigation
When looking to irrigate, factors such as water source, harvesting capacity, and usage volume will all need to be considered.
Water Source
Harvesting water from a roof, filling up from a bore or dam will impact the size of tank that will be most optimal for you.
Harvesting Factors
The size of your roof catchment area, in addition to your annual rainfall will determine how much water you can harvest.
Domestic Usage Volume
Having an idea of what domestic functions you intend to connect to your tank and how often each will be used will be advantageous.
Total Volume
It's better to have water and not need it, than to need water and not have it. It may pay to install a bigger tank to mitigate running out of water.
