Creative Ways Aussies Use Compact Tanks
When most people think about water tanks, they picture big, bulky giants taking up space on farms or in backyards. But for many Aussies, small water tanks—ranging from 200 litres to 5,000 litres—are the perfect size for practical, everyday water-saving solutions.
Whether you’re short on space, living in a metro apartment, or simply looking for a budget-friendly way to store rainwater, small tanks offer surprising flexibility. In this guide, we explore some of the most clever, unusual, and smart ways Australians are putting small water tanks to use—and why The Water Tank Factory is the best place to start your journey.
1. Garden Irrigation—Made Simple
One of the most common (and effective) uses for small water tanks is garden watering. A 500L or 1,000L poly water tank can collect enough rainwater from your roof to keep a veggie patch or flower bed thriving all year round.
Many savvy gardeners pair their tank with a small pump to create a fully functional irrigation system, saving hundreds on water bills and keeping their plants chemical-free. If you’re on a tight city block, a 200L or 500L slimline tank can be tucked under a window, eave, or narrow side passage.

2. Tanks for Tiny Homes & Granny Flats
Tiny homes and granny flats are booming across Australia, and compact water tanks are a perfect match. When plumbed into greywater or used for toilet flushing, a 1,000L to 2,000L water tank can provide a highly efficient off-grid or semi-off-grid solution.
These tanks are ideal for locations with limited plumbing access, and many customers find they can mount the tank alongside the home or even underneath in the case of underdeck tanks.
3. Pet & Livestock Hydration Stations
For rural properties and hobby farms, smaller tanks serve as reliable hydration hubs for animals. Whether you’re watering horses, chickens, alpacas or even a couple of sheep, a 500L or 1,000L tank can be hooked up to a trough to ensure clean drinking water.
Pair the tank with a float valve and you’ve got a self-regulating system. They’re also great for dog agility parks or kennels needing low-maintenance watering systems.
4. Water Tanks for Fire Protection
While large 10,000L+ tanks are often required for rural fire-fighting, small water tanks can also play a role in fire preparedness. A 2,000L poly tank connected to a pump and hose reel provides an emergency water source for perimeter wetting or spot fires.
It’s a popular option in bushland-adjacent suburbs or as a secondary tank closer to the house for quick response.
5. Rainwater Collection on Apartment Balconies
Here’s one most people haven’t considered: vertical slimline tanks on apartment balconies. While subject to building approvals, a 200L to 300L water tank can collect runoff from awnings or balcony roofs and be used for watering balcony gardens, cleaning, or even flushing if plumbed appropriately.
Urban gardeners use these to create self-sufficient micro-gardens, proving that you don’t need a backyard to benefit from rainwater harvesting.
6. Portable Water for Camping & Off-Grid Cabins
For adventure seekers or remote property owners, 500L–1000L water tanks make excellent portable storage options. Mounted on trailers or placed next to solar cabins, these tanks can supply shower water, cooking water, or even be pressurised for cleaning equipment.
Lightweight poly tanks from The Water Tank Factory are durable and UV-stabilised—ready for Australia’s toughest conditions.
7. Wicking Beds & Aquaponics Systems
A surprising number of customers use small tanks as part of aquaponics or hydroponics setups, or to feed wicking garden beds. The tank acts as a water reservoir, keeping the system thriving even during hot spells.
With minimal evaporation and high efficiency, a 200L to 500L water tank can easily support an entire raised bed garden.
8. Driveway, Deck & Side-Passage Installs
Don’t have a backyard? You can still harvest rainwater. Tanks like the 2,000L Slimline Water Tank and 5,000L Upright Urban Tank are specifically engineered for narrow spaces, including side paths and courtyards.
With smart layout and colour choices, they can even complement your outdoor design. At just 625mm wide, our 2000L Slimline fits where others won’t.
Why Small Water Tanks Punch Above Their Weight
When it comes to water storage, bigger isn’t always better. Small tanks are more affordable, easier to install, and serve a wide range of purposes from urban gardening to rural utility. They’re the unsung heroes of water sustainability.
And with Australia’s rainfall becoming increasingly unpredictable, storing even small amounts of rainwater makes good environmental and economic sense.
