GTARS System Operation Overview


Gray water first enters the system by flowing into a diverter box. This diverter box will direct the gray-water into a waste bladder, which acts as a holding tank for the water that is to be processed by GTARS. If this bladder is full and/or if the GTARS unit is not in operation, the diverter box will direct the incoming gray-water to flow into a secondary wastewater containment tank. The wastewater line from GTARS also flows through this box to be directed to wastewater.

Prefilter & Black Flush Automation


A source pump draws gray-water from the wastewater bladder and pumps it through the system prefilter. Under normal operation, the grooved discs in the filter are pressed together with a solenoid, and water is forced to flow through these grooves. When the filter begins to clog up, the solenoid releases, allowing the discs to separate. Then water and air are back flushed through the filter, clearing out any particulate which the discs had captured. Then the solenoid recompresses the discs, and the cycle can repeat.


After flowing through the prefilter, the water will be collected in a prefiltered water tank. A feed pump pulls water from this tank and pumps it into the microfilter loop. The system has 2 ceramic membranes; the cleaning and back-flushing of these membranes are fully automatic, requiring no user input. The permeate (clean) water from the membranes will flow through a carbon filter and will be topped up with chlorinated clean water.

Service Chemical Water Treatments


Once the system is set up and operational, it is designed to run without user interaction except for the replacement of dosing chemicals water treatment based on the system size. All the normal operational and cleaning processes will be fully automatic.

Our world is changing and it is time we start recycling water from our homes and buildings. Recycling gray water will reduce the burden of huge water treatment plants and bring a more economic solution to sustainable living.


Recycling water represents more than 50% of water daily consumption on average. Why let this used water destroy our earth, let it be recycled and used saving money for fresh water and become more independent and less water dependent.


Residential water use (also called domestic use, household use, or tap water use) includes all indoor and outdoor uses of drinking quality water at single-family and multifamily dwellings.These uses include a number of defined purposes (or water end uses) such as flushing toilets, washing clothes and dishes, showering and bathing, drinking, food preparation, watering lawns and gardens, and maintaining swimming pools. Some of these end uses are detectable (and measurable) while others are more difficult to gauge.

Phoenix H2O has been designing gray water recycling systems to integrate into new construction of buildings and homes. By separating a buildings piping system, buildings can recycle shower, sink and washing machine water in a closed circuit system saving thousands of dollars in public water supplies.  Sink water will be always supplied from a public sources while all the rest of the water from showers and washing machines will be recycled and used on a continued bases.
