Frequently Asked Questions

How often is it necessary to empty the sludge from the wastewater treatment plant?

Generally, due to the high efficiency of the total oxidation system, sludge buildup is very low compared to traditional septic tanks. An annual inspection is recommended, and emptying is usually only necessary every 1 or 2 years, depending on the actual usage by the 11 to 14 residents.

Does the motor consume a lot of electricity continuously?

No, the system is designed with energy-efficient technology. It operates using optimized intermittent cycles to inject the necessary oxygen without significantly increasing the electricity bill, ensuring economical operation 24 hours a day.

Does the adjustable cover remain visible in the garden?

The mini dome with adjustable lid is designed to sit flush with the ground or slightly raised, depending on installation requirements. Its discreet design includes safety locking mechanisms to prevent accidental access, allowing it to blend harmoniously into garden areas.

Can you pour regular cleaning products down the drains?

Yes, you can use common, environmentally friendly household cleaning products. However, you should avoid using large amounts of harsh chemicals, excessive bleach, or solvents, as these could disrupt the bacterial flora responsible for the biological purification process.
