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 perfectly prepared to withstand prolonged periods of inactivity, typical of second homes, without losing its biological capacity or deteriorating, automatically resuming its optimal functioning as soon as it receives flow again.

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 aeration system and to empty the accumulated sludge annually or biannually, depending on the actual use of the property throughout the year.

Does the adjustable cover make it easy to install on any type of floor?

Indeed. The adjustable dome or cover allows for overcoming small differences in ground level and adapting the exact height to ground level during the undergrounding process, which considerably reduces the time and complexity of the civil works.

Does it comply with current regulations for wastewater discharges?

Yes, the total oxidation process guarantees optimal purification levels that allow compliance with the legal parameters established for the authorized discharge of treated water, thus protecting the natural environment and groundwater.
