Wet systems use an underground network of pipes to channel rainwater collected from your roof directly into your tank.
These systems are called “wet systems” because the pipes remain filled with water until additional rainfall flows from the gutters, pushing the stored water into the tank.

Dry systems offer a straightforward approach to rainwater collection, with water flowing directly from the roof into the tank.
Known as “dry systems,” these setups ensure the pipes remain empty between rainfalls, as water is not retained in the system once the rain stops.

Collect rainwater directly from your tank roof with Pioneer’s exclusive Smart Water Savers. This innovative system eliminates the need for gutters, reducing debris and contamination while allowing you to harvest up to 25% of your tank’s capacity efficiently.

Your rainwater tank should complement your home and reflect your personal style. That’s why Pioneer Water Tanks offers a variety of colors and optional features, allowing you to customize your tank to suit your needs and surroundings.
The average Australian uses around 120,000 litres of water per year. Fortunately, this doesn’t mean each person in a household requires that much water storage. These figures are based largely on suburban usage, where significant water is used for irrigation and toilet flushing. In contrast, rural and semi-rural homes typically consume much less water.
Pioneer Water Tanks estimates that a rural household generally needs about 30,000 litres of water storage per person. Tanks exceeding this size are usually adequate for most households relying solely on rainwater. However, actual water storage needs will vary depending on annual rainfall and the catchment area of the home.
Most poly rainwater tank manufacturers offer capacities up to 50,000 litres, which may not be adequate for households fully reliant on rainwater—particularly those with more than one or two occupants.
Pioneer Water Tanks offers a wide range of high-quality steel water tanks, with capacities starting at 12,200 litres and extending up to 500,000 litres. For larger or more specialised storage requirements, custom solutions are also available for commercial and industrial applications.
As water storage needs increase, steel tanks from Pioneer Water Tanks present a cost-effective and dependable long-term solution.
The space required for a rainwater tank will depend on its size. As a general guideline, it’s recommended to have an area at least 2.5 metres wider than the tank’s diameter.
This allows for a 1-metre clearance around the tank for the sand pad, ensuring a stable foundation and minimising any potential installation issues.
For tailored advice and a smooth installation process, customers are encouraged to contact their local Pioneer Water Tanks dealer, such as NSW Water Tanks.
