Poly Round Tanks

Conserve water with a poly water tank from Roofing Options. We provide a full range of poly rainwater tanks, ideal for collecting Victoria’s often sparse rainfall for household or garden use. Our plastic rainwater tanks in Melbourne come in many sizes to suit the capacity of your property and roofline.

Poly tanks have many advantages – they’re lightweight, making them easy and cost-effective to deliver and position, as well as durable, meaning your investment will last a long time and keep their good looks, rain or shine. Plastic tanks come in a variety of colours, so we’re sure we can provide one that fits into the colour scheme of your home and garden. We also offer rectangular plastic water tanks to make the most of smaller spaces.

Looking for durable, affordable Plastic Tanks?

All our plastic tanks are very strong and durable; they come with a 10-year warranty so they’re built to last. At Roofing Options Centre we only sell plastic tanks that are quality certified and approved to Australian Standard AS/NZS 4766. Which means the water tanks must pass very stringent tests to ensure they’re safe and reliable for their intended use.
