The same comfort. Up to 98% less water, every flush.
the problem
Drinking water deserves better than a flush.
A toilet draws from the same supply as the kitchen tap. Each flush uses 6 to 8 litres of water that has been filtered, disinfected and tested to drinking standard, for a task that has never required it.
What a flush needs
Enough water to carry waste away.
What it receives
6–8 litres of drinking water, every time.
Where a household’s water goes
40% toilet flushing60% showers, cooking, cleaning and drinking
alpha one
Invisible behind the wall. Visible on the bill.
alpha one fits behind the wall you already have, between the bowl and the drain. It reads every flush, separates solids from liquids within a fully enclosed unit, filters what can be recovered, and returns most of the water for the next flush — before any of it reaches the pipe. The way you use the toilet doesn’t change. What changes is that the water gets reused.
Retrofits behind a standard wall-hung bowl and carrier frame — no new plumbing routes.
The entire separation, treatment and reuse system, inside the space behind your wall.

the separation system at its core is patent‑protected, and built to become the reference for water‑efficient sanitation.
how it works
Three steps. Zero effort.
01
Separation
The moment you flush, solids and liquids are fully separated inside the module — automatically, and entirely out of sight.
02
Treatment
The system cleans itself automatically after a set number of cycles, and is built to keep working even if a part fails. Worst case, the toilet simply behaves like a standard one again.
03
Reuse
High‑performance filtration returns clean water to the system, ready for the next flush, instead of sending it straight down the drain.
Compact housing for easy access. Built to fit the bowl you already own. The outlet turns to reach whichever way your drain runs.
the numbers
One Swiss building. One year. 98% less water.
10 toilets. 20 residents. Five flushes a day, each. Same building, two scenarios.
Standard fixture219 m³ · CHF 1’314 /yr
With alpha one4.38 m³ · CHF 26.28 /yr
CHF 0.00
saved, every year, in that one building alone.
Based on Swiss national averages of CHF 2 per m³ for potable water and CHF 4 per m³ for wastewater treatment. One toilet per apartment, two occupants per apartment.
care & upkeep
A system that looks after itself.
See it
A running record of exactly how much water and money each unit has saved.
Catch it early
The system watches itself for leaks or blockages and flags anomalies automatically.
Fix it fast
Every unit is backed by a certified installer network, with a repair window of 48 to 72 hours.
Fail safe
If something does go wrong, the toilet still flushes. alpha one is built to fail open, never closed.
