Among all the advantages offered by the Advanced Enviro))Septic pipes within System O)) wastewater treatment systems, it is its completely passive operation that is most note-worthy. A system that is designed, installed and used in compliance with our guides requires no maintenance or component replacement.


Knowing that System O)) solutions require little to no maintenance to operate at peak efficiency, why would we want to spend money on additives for septic systems?

The DBO Prof is clear - no additives in your System O)) treatment system

To reduce sludge build-up?

Certainly, these additives have an impact on the sludge in your pre-tank. However, as many regulations require regular emptying of these tanks, there is no need to reduce this build-up.

To increase the biodegradation process of the pollutants?

In sufficient quantity, these additives allow for faster and more effective biodegradation of organic matter in the pre-tank. But this tank’s role is first and foremost as a decanter, not a bioreactor.

Organic Overload

Adding additives to pre-tanks can lead to a degradation of pollutants that should normally remain in the tank and be eliminated when it is emptied. This degradation leads to an increased solubilisation of organic matter in the clarified water of the pre-tank, which is then routed to the treatment unit downstream. This organically overloaded water has then a higher risk of clogging the system sand.

to conclude

A System O)) wastewater treatment system that is designed, built and used correctly should never need an additive to ensure its proper functioning, and in fact, these additives can impede the system’s proper operation.


DBO Expert recommends avoiding the use of additives, be it through the plumbing or directly in the septic tank.


As a System O)) installation owner, the best prevention method will always be to respect the user guide, maintain the effluent filter twice a year and ensure the system is inspected regularly!
