Rhizopod System

A ‘no-release’ evapotranspiration channel used to disperse on-site and decentralised treated wastewater into the atmosphere.

For difficult sites where soil types, set-back distances, or a limited available footprint has meant that other systems are not practical

The Rhizopod® system has been specifically developed for use on difficult sites where soil types, set-back distances, or available footprint has meant that other forms on water dispersal are not practical. Pre-treatment is provided through septic tanks and/or package treatment units. The Rhizopod® channels are designed to resemble a raised garden bed. Treated water is pumped through a series of pods planted with a variety of plants. Any water not used for evapotranspiration is stored in a balance tank and recirculated through the pods until used.

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. 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.

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.

Rhizopods® are being used for single domestic systems through to decentralised systems for small communities of 1600EP. 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. The water’s passage through the Rhizopod® system polishes its quality and reduces the volume available for external recycling.
