Our Quality Farm Water Storage Tanks

In the world of farming, your liquids, whether water, fuel, or liquid fertiliser, are your most valuable assets. But in the harsh Australian climate, simply “having a tank” isn’t enough. You need a storage solution that can handle 40°C days, inquisitive livestock, and the heavy hydrostatic pressure of thousands of litres of liquid.

At Polymaster, we’ve been part of the Australian rural landscape since 1994. We don’t just make tanks; we build infrastructure that helps your farm run more efficiently.

Here is a breakdown of the essential “Farm Tanks” every modern property needs.

1. High-Capacity Rainwater Storage

When the rain finally comes, you need to catch every drop. Our round rainwater tanks are the backbone of rural properties across Australia. From the standard 22,500L unit to the massive “Big Bertha” 50,000L tank, we ensure your household and stock have a reliable reserve.

Pro Tip: Look for the AS/NZS 4766 certification. This ensures your tank won’t bulge or crack under the weight of 50 tonnes of water.

2. Stock Watering: Tanks & Troughs

Livestock health starts with clean, accessible water. Our range of troughs and stock watering tanks is designed to be “stock-proof.”

• Stock Watering Tanks: These combine a large water reserve with an integrated trough. It’s a “set-and-forget” solution that ensures your cattle always have water, even if a pipe breaks elsewhere on the property.

• Sweep Troughs: A favourite for hygiene-conscious farmers. You can clean these in 5 minutes thanks to the sweep-out base—no more spending half an hour scrubbing slime.

3. Molasses & Liquid Fertiliser Storage

Storing heavy liquids requires a different kind of engineering. Because molasses and liquid fertilisers are much denser than water, they exert significantly more pressure on the tank walls.

Our Molasses and Fertiliser Tanks feature:

• Extra Wall Thickness: Specifically engineered for liquids up to 1.5sg (Specific Gravity).

• Specialised Outlets: Heavy-duty brass outlets that won’t corrode or seize.

• One-Piece Construction: No vertical seams, which are common failure points in lesser tanks.

4. Farm Diesel Tank Storage: Bulk & Portable

Time is money during harvest or seeding. Having fuel where you need it, when you need it, is a game-changer.

• Bulk Farm Diesel Storage: Available in single or self-bunded (double-walled) options for maximum safety.

• Farm Diesel Ute Packs: Ranging from 100L to 800L, these fit perfectly in the back of your ute to refuel equipment in the paddock.
