Frequently Asked Questions

For exactly how many people is this water purifier recommended?

This model with a capacity of 6500 liters is designed to fully cover the daily sanitation needs of homes inhabited by between 8 and 10 equivalent inhabitants, perfectly adapting to large families or properties with high seasonal occupancy.

Does it require continuous power consumption?

Yes, the total oxidation system requires a small aeration pump (compressor) that intermittently injects oxygen to keep the microorganisms responsible for purifying the water alive. This motor is optimized for very low energy consumption.

Are there any unpleasant smells produced during its operation?

No. Unlike conventional septic tanks that operate without oxygen and generate foul-smelling gases, this system constantly introduces air, performing a clean aerobic process that completely prevents the appearance of bad odors in the garden or outdoors.

How is sludge maintenance and emptying performed?

Maintenance is simple and mainly consists of periodic checks of the aeration system and emptying the sludge accumulated at the bottom, the frequency of which will depend on the actual use, usually ranging between one and two years by means of an authorized Cuba truck.

Is it difficult to install on the ground?

Thanks to its compact design and adjustable dome cover, underground installation is straightforward and versatile. However, it is recommended that installation be carried out by qualified civil engineers and plumbers to ensure proper leveling, soil compaction, and connection to the sewer system.
