A treatment that is as natural as, well, Nature

A passive treatment system like the System O)) involves processes that often occur naturally in the environment. So it requires little or no maintenance – including draining pipes or replacing filter media – and no power.

Water, water and more water!

If you are not connected to your municipality’s sewer systems, you need to have a septic tank to collect the wastewater from your home. But it cannot manage the amount of water a family produces on a daily basis: showers, toilet, dishwasher, laundry, and more! That’s a lot of liters of water per day that need to be put back safely into the environment.

The septic tank retains the solids, but the liquids must be distributed, treated and infiltrated into the ground – and this is where System O)) solutions come into play. They are the only solutions that distribute, treat and infiltrate wastewater in a single activity.

Long live bacteria!

Wastewater is treated by aerobic and anaerobic bacteria that settle on the edges of the perforated pipes are at the heart of the System O)) septic systems. These two types of bacteria feed on pollutants in the water and control each other to keep the biomass from growing too large and therefore having to be removed.

How does it work? 1

A comfortable sand bed

The filtering sand that covers the pipes is an integral part of the treatment. Its role is to allow the water to drain at a specific speed: slowly enough to allow the bacteria to do their job, yet fast enough to avoid flooding. Its granular composition is therefore very distinctive, and very important.

Take a deep breath

Bacteria need oxygen, whether dissolved for anaerobic bacteria, or in the air for their aerobic cousins. That is why System O)) solutions are ventilated, which means there is a continuous supply of air inside the pipes. The air enters through the installation’s vent and exits through the house’s roof plumbing vent. Septic tank odors therefore go up and out into the sky, and not through the patio door.
