Frequently Asked Questions

Is this water treatment plant suitable for a second home that is not used for months at a time?

Yes, this system is especially recommended for second homes. Its total oxidation technology adapts perfectly to extended periods of inactivity, reactivating quickly and efficiently as soon as the home is occupied again, without losing purification capacity or causing operational problems.

What maintenance does a septic tank with total oxidation require?

Maintenance is minimal thanks to its automated management. It is recommended to perform a periodic inspection of the electromechanical components and to empty the accumulated sludge annually or biannually, depending on actual usage and the number of people who regularly use the facility.

Are bad smells generated during the purification process?

No. Unlike traditional septic tanks, this advanced system uses constant aeration to maintain the aerobic process, completely preventing water putrefaction and the resulting unpleasant odors outside.

How does the adjustable lid system work?

The adjustable dome or cover allows you to adjust the height relative to the ground surface during installation. This greatly simplifies leveling the access opening of the treatment plant with the garden surface, ensuring convenient, aesthetically pleasing, and safe access for maintenance.
