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 system.   Silently and continuously nature is breaking down waste all around us.  Unlike mechanical treatment systems the WormSmart System at the point of entry into the tank immediately separates the solids from the liquids.  Worms then rapidly convert the waste into humus.
The humus works as natural filtration. This, along with all of the filtration inbuilt into the tank at manufacture, 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 quietly and efficiently treated.  The rest is left to nature and the sub surface absorbtion trenches.
Plants require an adequate supply of water to achieve satisfactory production nutrients and trace minerals are also needed for growth.  Most plants also require well drained, aerated, soils.
Sub soil 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 and worm eggs provide organic matter whereby if the soil characteristics are favourable - ie. Sufficient clay – 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 sub soil absorbtion trenches and along with the worm eggs hatching provide beneficial aeration of the soil to minimise water logging of the trenches.  This, along with suitable plants, means that the standard 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 combination of worms and maximum bio filtration means the right combination of organic matters enters the soil preventing unwanted smells associated with most primary septic systems.
After the worm eggs, worm castings (worm poop) and the treated liquid combine in the trenches, nature takes over.  The worms breed, the plants you plant thrive and the sun, via the plants, evaporates the liquid.  ‘NATURE AT ITS BEST’.
In contrast, plain old septic tanks and mechanical aerated waste treatment plants largely work on an anaerobic process which are liquid based – ie. Solids decomposing by micro organisms which need ideal conditions to survive.  They must use high energy aerators to pump oxygen into the system.  Even so only a few parts per million of oxygen is available.  In the WormSmart System around 200,000 parts oxygen per million is available.  This is helped also by the air shaft and wind driven ventilator which is an integral part of the system
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.
