The worms breed, the plants you plant thrive and the sun, via the plants, evaporates the liquid.

WORMSMART IS VERY DIFFERENT TO THE OLD SEPTIC TANK AND AERATED SEWAGE TREATMENT SYSTEMS
WormSmart Waste Treatment System This Bio-logical Waste Treatment System has been designed specifically to process household sewage and waste water in a single tank without the need for a complex assortment of pumps, blowers, aerators, chlorine dosing units etc that most other treatment plants use.
The WormSmartSystem is just that – SMART!  It works with nature.   The worms intercept the solids, including food scraps from your sink, and digest them – treating the faecal matter along the way.
By working with nature and observing nature at work it was not hard to decide which path to follow in developing our proprietary Bio-Filtration system.  Silently and continuously nature is breaking down waste all around us.  Unlike mechanical treatment systems the WormSmart System lets the worms and bio-filtration do the work. 
The design of the system ensures maximum surface area for good bacteria to cling to and this in turn cleanses the wastewater as it passes over the good bacteria.  That, along with the worms consuming the solids, allows what leaves the tank to be efficiently treated, in the land application.
The treated effluent can be put through either old-fashioned low maintenance trenches or low-pressure sub surface irrigation.  Low-pressure sub surface irrigation can be utilised for growing of plants and shrubs in a specific area – or multiple areas.
Sub surface irrigation with treated sewage can be beneficial to plant growth while evapotranspiration returns water to the environment with minimal impact.  The added benefit of a WormSmart Bio-Logical Waste Treatment System is that the worms break down the solids, faeces, toilet paper and other organic matter from your kitchen sink (unlike most expensive treatment plants) by way of vermiculture.  The wet decomposition chamber incorporated in the units design acts like a mini ecosystem – much the same way as nature works on the floor of a rain forest.  Vermiculture, like nature, is an effective way to treat faecal matter.
The worm castings (worm excreta) provide organic matter whereby if the soil characteristics are favourable then most of the trace pollutants are removed by final bio-chemical processes in the soil.  The worm waste adds sufficient organic matter to the soil and along with the worm eggs hatching provide beneficial aeration of the soil to minimise water logging.  The WormSmart system is a better way to process sewage than the more expensive and complex mechanical waste treatment systems.  Less mechanical parts means less servicing and major cost savings long term.
The wind driven vented pipe stack on the WormSmart system provides natural ventilation to the internal chamber of the system.  The stack works like a big lung.  The ventilator and pipe work as a passive air exchange system.  As warm air rises into the pipe and/or the ventilator turns by local wind pressure or stack driven pressure, air is extracted and drawn in through screened inlets in the side of the above ground access riser.  This natural ventilation system harnesses the principle of the venturi effect.  This system is quiet, efficient and provides no cost running ensuring essential oxygen for micro organisms to flourish whilst providing oxygen and cooling for the worms to efficiently process the waste into liquid castings – soil fertiliser.
