Underground Rainwater Tanks from Action Tanks

The Action Underground Tank is a modern-day solution for water tanks and rain harvesting.

It's a 'space saving' underground tank that is not only lightweight and easy to install (with lifting lugs at top of tank for ease of maneuverability), but also designed to reduce hydrostatic lift (popping) with a bell-shaped structure and feet at the base.

Manufactured from finest quality food-grade Australian polyethylene the tank will not crack with ground movement or leach materials into the water.

The 150mm inlet, compared to a 600-800mm of other tanks, provides a child-safe and aesthetically pleasing solution.
