Who is a 50 000L water tank suitable for
50 000L water tanks are the tank size most suitable for a single person's water storage, or for households looking to expand their water storage by harvesting water off of a shed, garage or similar structure. The Pioneer GT50 is the closest tank size to a 50 000L water tank, coming it at 48,693L.
The GT50 is the first size where a steel water tank starts to become more practical and on occasion more affordable than a poly tank, particularly with the added fire protection a steel tank provides over a poly water tank. Pioneer have many sizes of water tanks larger than this also.
Many people purchasing a rainwater tank may have no access to mains water, or be looking to reduce their reliance on it, so it is important to ensure you have more than enough rainwater harvesting ability, and a large enough water tank for your needs. If you are looking to be completely self sustainable, a tank larger than 50 000L might be better for your needs.
If you're looking to determine if a 50 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 GT50 and GT60 model water tanks.
Tank Model | Gross Capacity (Litres) | Gross Capacity (Gallons) | Diameter | Height |
---|---|---|---|---|
GT50 | 48,963 | 10,770 | 5.35 m | 2.18 |
GT60 | 61,968 | 13,631 | 6.02 m | 2.18 |
Gross Capacity is the total tank volume not including the water loss above the overflow or below the outlet.

The Pioneer Water Tanks Difference
Pioneer Water Tanks have been manufacturing 50,000L rainwater tanks that Australian families can rely on for over 30 years, and continue to strive to remain at the forefront of innovation and quality in the industry.
All Pioneer Water Tanks, regardless of if they're 50,000L or 500,000L are manufactured in Australia, from Australian Zincalume® or Colorbond® Steel, and Pioneer remains a 100% Australian family owned business. Our dealers - who can be found all across the country - are also locally owned and operated family businesses, and work exclusively with Pioneer Water Tanks.
The Pioneer V-Lock® tank wall profile is specially designed with water storage in mind, not only providing superior strength and longevity, but also protecting your liner from the stretching and stress that can come with the filling and emptying of a regular corrugated wall panel.
All of the 50,000L water tanks Pioneer manufactures come with our 20/20 Warranty, which is a 20 year conditional structural warranty as well as a 20 year conditional warranty against water leakage.
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.
