Corrugated water tanks in Nowra, NSW offer a distinct set of advantages that make them an ideal choice for homes, farms, and businesses throughout the Shoalhaven region, including:


  • Superior Strength & Durability: The corrugated design isn't just for looks; it adds immense structural rigidity to the tank walls.

Made from high-grade, corrosion-protected Australian steel, these tanks are built for decades of reliable service.
  • Longevity and Low Maintenance: Thanks to their robust construction and high-quality materials like Zincalume® or Colorbond® steel, our corrugated water tanks require minimal upkeep. They are resistant to rust, cracks, and UV damage, ensuring you spend more time using your water and less time worrying about maintenance.
  • Ideal for Larger Capacities: If you have substantial water storage needs for agricultural use, large households, or firefighting purposes, corrugated steel tanks are the perfect fit. We provide a wide range of sizes, often excelling in larger volumes where their strong construction is most beneficial. This makes them a top choice for rural properties across the Nowra region.

AQUAPLATE Steel, Colorbond Colours, and What to Know Before You Buy

Knudsen Tanks & Roofing fabricates corrugated water tanks in Nowra, NSW, using BlueScope AQUAPLATE steel, purpose-built for rainwater storage and drinking water contact.


What Steel Does Knudsen Tanks Use, and Why Does It Matter?


AQUAPLATE steel comprises a Zincalume-coated steel shell with a food-grade polymer film bonded to the inside. The strength of steel sits on the outside while your water never touches bare metal. AQUAPLATE meets AS/NZS 4020 for products in contact with drinking water, so what comes off the roof stays clean from inlet to outlet. The internal lining also prevents rust pitting that can shorten the life of bare steel tanks.


Colorbond Colour Options for Your Corrugated Tank

Your corrugated water tank can complement your home's existing roofline, shed, or fencing. AQUAPLATE steel is available in unpainted and pre-painted Colorbond forms, where the outer side carries a Colorbond colour while the inner side holds the food-grade poly coating. A corrugated profile with low-glare finish is available across 22 or more Colorbond colours. Call Knudsen Tanks & Roofing on 02 4443 4066 or visit the products page to ask about available colours for your order.


Capacity Options to Suit Nowra Properties

Knudsen Tanks can supply corrugated water tanks across a wide range of sizes, from compact units suited to residential rainwater top-up through to larger rural storage, catering to both residential and commercial sites.

Frequently Asked Questions About Corrugated Water Tanks in Nowra

  • How Long Do Corrugated Steel Water Tanks Typically Last?

    AQUAPLATE tanks can offer a long service life when installed and maintained correctly. Lifespan varies depending on local conditions, water quality, and maintenance, so ask Knudsen Tanks about the specific material warranty applicable to your tank.

  • Are Steel Corrugated Tanks Safe for Drinking Water?

    Yes. Tanks fabricated from AQUAPLATE steel meet AS/NZS 4020:2018, the standard for products in contact with drinking water. Ensure your first-flush diverter and gutters are in good condition to keep collected water clean.

  • How Do Steel Tanks Compare to Poly Tanks?

    Steel corrugated tanks offer a traditional aesthetic that suits the rural and semi-rural properties common around the Shoalhaven. Poly tanks may suit tighter suburban spaces. Both can store rainwater effectively when manufactured to relevant Australian standards.

  • Can I Get a Custom Size to Fit My Property?

    Knudsen Tanks offers made-to-measure tanks for the perfect fit. This is particularly useful on Nowra rural lots where non-standard footprints or height restrictions apply.
