How UBI AQUA Waste Water Treatment Works

Wastewater Treatment Systems are individual systems that use the soil to dispose of small wastewater flows. They are ideal for individual homes, and are typically well-suited for rural or large lot settings where centralised sewage treatment is impractical.
The Ubi Aqua Waste Water treatment system treats your household wastewater by temporarily holding it in the water treatment tank, where heavy solids and lighter scum are allowed to separate from the wastewater.

The first compartment is a settling chamber, where solids and liquids separate, and some anaerobic digestion occurs. From here, the effluent passes through the aeration chamber. A pump supplying a constant flow of air oxygenates the water, creating optimum conditions for the decomposition of organic compounds.

The third compartment allows further removal of particulate matter and disinfection before the effluent leaves the unit. After spending time in the chlorination/disinfection chamber, the treated effluent is pumped through irrigation lines to the disposal area as per required design. This effluent then slowly seeps into the subsurface soil where it is further treated. This process, in a properly functioning water treatment system, does not pollute the groundwater.

Landscaping And Irrigation Considerations

How the area around a Ubi Aqua water treatment system is managed is just as important as how the system itself is maintained. Planning and planting the right kind of vegetation can help keep the system in tip top condition. When choosing what to plant, consider which plants will do best in the local soil type, also considering which ones can cope best with regular daily doses of nutrient-rich wastewater.


Ubi Aqua system is back with a 15-year warranty on the tank, 2 years on the Davey Pump and 1 year on the diffuser.
