What if every drop of water in your home regained its value? Groupe O imagines a world where water circulates, regenerates, and is shared—without ever being wasted. In a context of water stress and climate disruption, we’re reinventing the relationship between housing and nature: an approach inspired by the living world, where technology and ecosystems move forward hand in hand.
A shared vision: making every drop a resource
Behind the term bio-regeneration lies a simple idea: when water is managed intelligently, it can be reused again and again—without polluting or wasting. Groupe O relies on biomimicry to create autonomous, clean, and sustainable water systems.
The goal: to enable every home, every garden, every pool to close its own loop, in harmony with its environment.
The three pillars of Groupe O
InphytO® – Natural wastewater treatment through constructed wetlands
InphytO® is the French specialist in constructed wetland treatment: a 100% natural process that treats domestic wastewater using plants and microorganisms. Its flagship innovation, the PHYTOSTATION®, is an effective replacement for septic tanks and compact treatment units.
No electricity, no pumping-out, and recognized by the SPANC, it purifies water the way natural wetlands do.
The result: a garden that becomes a living ecosystem—odor-free, beautiful, and beneficial for biodiversity.
To go further: eco-friendly on-site wastewater treatment • reuse of treated wastewater.
O bioPool® – The Bio Pool that’s self-sufficient in water & energy
With O bioPool®, the pleasure of swimming takes on a whole new meaning. Here, there’s no chlorine and no salt: pure, soft, crystal-clear water filtered biologically—like in a river.
Living biofiltration and intelligent control (automation, sensors, cycle optimization) ensure simplified maintenance and minimal energy consumption. The pool blends into the landscape (wood, mineral) for a truly natural well-being experience—self-sufficient in water & energy.
Infinit’O™ – Circular water for the autonomous home
Infinit’O™ is the final stage of the cycle: a complete water management system designed to make each home nearly independent from the network. It captures rainwater, regenerates it naturally through biofiltration, reuses it multiple times (toilets, cleaning, garden, pool), then returns it—pure and living—to the groundwater.
Driven by sensors and embedded algorithms, Infinit’O™ tracks flows, analyzes quality, and anticipates needs. It’s the promise of a resilient, water-efficient home, ready for the world of tomorrow.
Biomimicry: nature as a model
Wetlands, rivers, and forests recycle water without ever polluting it.
Groupe O draws inspiration from them to recreate these processes at the domestic scale: purifying plants, beneficial bacteria, mineral substrates, living filtration.
It’s a humble yet powerful technology, where engineering serves nature instead of constraining it.
Concrete benefits for the planet… and for you
- Major reduction in withdrawals: up to 90% water savings for certain uses.
- Very low energy consumption, intelligent control.
- No chemicals, no unnecessary polluting discharges.
- A direct contribution to local biodiversity.
- Increased property value through aesthetic, durable installations.
A nationwide network of committed experts
Across France, our partners install, maintain, and support solutions for constructed wetlands, biofiltration, and water self-sufficiency.
These trained professionals ensure the quality of installation and compliance of every project.

Toward regenerative living
At Groupe O, we believe it’s no longer enough to be “eco-friendly”: we need to be regenerative.
That means creating homes that give back to nature more than they take.
Thanks to our nature-inspired technologies, every household can become a driver of change—a virtuous link in the water cycle.
Your questions, our answers
Are Groupe O solutions suitable for all homes?
Yes, detached houses, vacation rentals, hotels, eco-hamlets: the systems can be customized to suit both the terrain and the intended use.
Can treated water be reused?
Yes. Depending on current regulations and the quality achieved, it can be used for watering, cleaning, and filling ponds and biological pools, significantly reducing the amount of drinking water used.
Is a major service required?
Very little: visual inspection, “gardener-style” maintenance, and automated monitoring via control systems (sensors, alerts, logs).
How do I know what size system I need?
It depends on the number of people in your household (in “population equivalents” or PE). For example, if there are two of you but the house can accommodate four people, it’s better to size it for four. That anticipates future changes. InphytO supports you in choosing and installing the solution that suits you.
