Stage 1
Primary treatment
All of the household waste flows into the primary chamber. This first stage acts like a regular primary septic tank. Harnessing the good bacteria that already exists and taking it onto the next stage.

ONE SERVICE PER YEAR
15 cents per day!
A family of four people will use about 15c per day on average with the Envirotech system. Compared to regular aerated systems you will save in excess of $200 a year on running costs alone, not to mention servicing and replacing costly consumables like filter media, air discs, diaphragms, filters and air blower units. Your Envirotech treatment system pump runs for approx. 30 mins per day, compared to regular aerated treatment systems that are always running an using costly power.

How the system works?
The Envirotech system replaces your septic, greywater tank and grease trap. It recycles all sewage (including solids from the toilet), greywater, and all other liquid from the household, into crystal clean odourless water for watering your plants & gardens.
Stage 2
Secondary Treatment
The secondary chamber acts as an additional settling chamber where gravity does the work. This chamber is designed to promote the creation of oxygen. This launches the aerobic biological process
Stage 3
Filter Pump-well
Perhaps the most important chamber in the all-in-one tank structure - in this chamber, any remaining fine particles will drop to the bottom before passing through to the sand filter. The liquid is held in this chamber and then pumped out to the A.S.F.
Stage 4
Aerobic Filtration
What started as ordinary household waste has now passed through a 3-step treatment process and is ready to be pumped into the Aerobic Sand Filter (A.S.F). Inside the filter it passes through a series of natural locally sourced, clean river stones, creating a far more natural and effective treatment than mechanical air blowers.
Stage 5
Filter Return Chamber
The filtered water then passes back into the filter pump chamber - also known as the "Filter Return Chamber". Here it is held for a period of time and then recirculated back into the Aerobic Sand Filter (A.S.F).
Stage 6
Clarifying Chamber
The clean, treated water now passes into the clarifying chamber, where it travels up through a fine cartridge filter that acts as a safeguard ensuring that if the system load has increased from a party then any remaining fines are removed here.
Stage 7
Final Pump Out
The crystal clear water travels from the clarifying chamber over into the pump-out chamber via a chlorinator before it is pumped out through a sprinkler line and onto green grass
