Thin Tanks can be free standing or joined together to form a partition or a fence.

Use any number of Thin Tanks to achieve the desired capacity.

Thintanks™are an Australian made product, manufactured in South Australia, New Zealand and South Africa from food grade, 100% UV stabilised polyethylene.

All Thintanks™ are designed by a professional consulting engineer in accordance with all AS/NZ Standards and designs confirmed with FEA testing.

The solid one – piece constructed Thintank™ is fitted with two (2) brass 20mm outlets [1000L and 2000L] or 25mm outlets [3000L] at the bottom of the tank allowing for easy linking of tanks.

The 2000L and 3000L tanks come standard with an inlet strainer basket with UV protection. The 1000L tanks have an inlet basket at both ends of the tank for inspection purposes.

A 90mm overflow flange is provided that can be fitted to either end of the tank [needs to be cut out with a 95mm hole saw].

“Rainwater Harvesting is rainwater captured from a roof into a container and is the 3rd largest source of water in Australia.”

“Rainwater harvesting is the first and most efficient element of an integrated water management system.”


Start today! A small tank can be plumbed into your toilet and washing machine saving over 20,000L of water a year. Rainwater harvesting can also help reduce stormwater management costs.
