The true underground tank from Action Tanks

Action Tanks, Split Master (Underground Rainwater Harvesting System) is a very cost effective underground alternate water source system for Residential & Commercial use.

This Underground System is 100% Australian made and owned and meets all statutory requirements - It is "A True Underground Tank" (available in 3000Lt, 4550Lt, 5000Lt or multiples of) and made from 100% Australian lightweight polyethylene.

The Split Master is so easy to install and derives the name from the separately located control box placed next to the house / garage. This design is extremely useful in small lot homes, or where space is an issue, as the Split Master is truly concealed.

The harvested water from the underground system has been designed to supplement the laundry, toilet, or hot water system via the Control Box.

Installed underneath the lawn, patio or driveway, it leaves plenty of yard space to be used as desired. Highly beneficial with block sizes becoming increasingly smaller in new homes.
