Tank Code:  TT3000

The 3000 litre ThinTank has been released to fill the requirements of those who want to maximise their storage capacity, but minimise the space they sacrifice for a tank.

At a depth of only 580mm, this slim tank still keeps true to its name, allowing it to be installed along side passages giving ample room to walk past or move those garbage bins and lawn mowers past the tank.

Freestanding installation is made possible by using a set of custom made End Brackets. For more information on installation options please click on the PDF installation guide below:


The aesthetics of this tank are also in keeping with the original ThinTanks design, giving that contemporary and sleek finish.


  • Solid one piece construction for maximum strength

  • Vertical and horizontal ribs with cross connectors – adds additional support to contain expansion when filled with rainwater

  • Has two brass 25mm outlets to allow easy interlinking of water tanks – maximise required water collection capabilities

  1. I am looking for price of a 3000 ltr thin tank and pump delivered to Tumut NSW if possible please if delivery not possible just price if I pick it up myself Thank You Keith

    • Hi Keith,

      Kind Regards,

  2. Hi, I’m replacing an existing rectangular 5000L steel tank that failed (supplier out of business). I’m hoping to increase storage to 6000L by connecting 2x 3000L slimline thintanks (TT3000) together adjacent to each other.

    The existing concrete base is 1.4m wide x 2.7m long with an additional 1m concrete “apron” around the slab and building.

    I couple of questions:
    1. Could I position 2x TT3000 tanks with their long edges back to back?
    2. Can I use the existing Grundfos submersible pump in the TT3000 tank?
    3. Can I connect / chain up the two tanks in parallel with the bottom connectors (instead of in series using the overflows)?

    Many thanks,

    • Hi John,

  3. Hello
    If I was to put the TT3000 on a reinforced slab, are you able to give me the necessary thickness for such a slab?
    Thank you

    • Hi Peter,

      Thank you for your enquiry.

      The slab for the 3000 litre Thintank needs to be reinforced with F82 steel mesh and at least 150mm thick.
