    Fantastic service from Lyn & Bec in the office and from Steve the delivery driver. We had two tanks delivered to Sydney despite the lockdown. Would happily recommend Tankworld.

  • Meg MacDonald

    We had our 45,400L rainwater tank delivered today. Ken was so lovely and very prompt with phone calls to keep us updated on when he would arrive. Michelle was so patient with my 101 questions about tanks and pads etc. Would highly recommend.

  • Phil Waine

    Great communication from Jamie, the truck driver. He let me know that he was slightly behind schedule to deliver the water tank. He was polite, efficient, friendly and completed a pleasurable purchasing experience! His driving was exceptional – wish I could reverse like that!! Happy to give Tankworld my money.

Why use a rainwater tank?

As the world population continues to grow and fresh water becomes scarcer, it is important that we learn how to reduce our usage and store our water. Water tanks can help by storing excess rainfall or snowfall so you don’t have flood your house every time there’s heavy rainstorm.

The earth is covered with 70% of water; however, two-thirds (63%) refer to glaciers and ice caps. As such, there’s plenty that needs protecting! Using a Water Tank can save money while doing your part to preserve this precious resource – all at the same time!
