Frequently asked questions about the total oxidation wastewater treatment plant

How does a total oxidation wastewater treatment plant work in a second home?

The system introduces oxygen in a controlled manner to promote the growth of aerobic bacteria that break down the organic matter present in wastewater. Because it is an advanced biological process, the equipment remains active even when the home is unoccupied, regaining its optimal performance almost immediately upon reopening.

Is it difficult to install this septic tank with an adjustable lid?

Installation is simple thanks to its compact design and the versatility of its adjustable lid, which allows it to be perfectly leveled with the surrounding ground surface. It is recommended to use qualified professionals to ensure the correct excavation dimensions and water inlet and outlet connections.

What maintenance does the GA90050 model require?

Maintenance is minimal due to its high level of automation. It only requires periodic checks of the aeration system and emptying of accumulated sludge, depending on the actual usage level of the house—a quick and clean task thanks to the easy access provided by its dome.

Can the treated waste be discharged directly into the environment?

Yes, the water resulting from the total oxidation process reaches a high degree of purification that meets the legal parameters for authorized discharge into surface water bodies, sanitation networks or for use in underground irrigation.
