Rhizopod® System Technology

The Rhizopod® system, formerly promoted as the Recirculating Evapotranspiration Trenches (RET) system, is designed to resemble a raised garden bed. Pre-treatment is provided through septic tanks and/or aerated tanks. The recirculating nature of the technology and the holding tank have resulted in a relatively small footprint for the Rhizopod® system. The Rhizopod® technology has been installed and operating since 1998. Arris Water can design, construct, maintain and operate Rhizopod® systems. The Rhizopod® system has been very popular at caravan parks and for small clusters of houses.

Water planners have used Rhizopod® systems to delay expensive capital works programs.

Many soil types are unsuitable for the long term application of effluent. Some sites are so close to environmentally sensitive areas that the required set back distances make the development of the land unviable. The Rhizopod® system imports soil suitable for the long term application of effluent, and treats and reuses it within a contained environment, minimising the applicable set back distances.

Rhizopods® are being used for single domestic systems through to decentralised systems for small communities of 1600EP.

Plants grown in the channel allow all the effluent to be reused; with a holding tank providing wet weather storage. This allows the Rhizopod® system to be successfully installed on sites with very poor soils and relatively close to environmentally sensitive areas. Rhizopod® system installations have been granted ‘no-release works’ licences under ERA 63 by the Queensland Department of Environment and Heritage Protection – which reduces the annual licence fee and the monitoring requirements. In 2015, Arris received product approval by the South Australian Department of Health. If required, the technology can be adjusted so that it produces ‘fit for purpose’ recycled water.

Arris Water can provide a contained treatment technology based upon the Rhizopod® system. This technology was developed by Ben Kele during his Master’s degree by research study at the Centre for Plant and Water Science at the CQUniversity. It has been known previously as the Kele System. The dual drivers for the development of the technology were to create a system that is independent of the local soil type and one that treated wastewater in a contained manner.
