Our Composting Toilet Systems
Aquatron Composting Toilet System
Uses a conventional household toilet pan - ideal for people who want a flush toilet that's also a composting toilet.
Swedish-Engineered Since 1986
One clever part, no moving parts. Momentum, centrifugal force and gravity split the solids from your flush water - so you keep a normal flushing toilet and let nature do the composting.
Farmstyle / Back Country
A waterless composting toilet with urine separation, built for permanent self-contained living - even where there's no water or power.
Off-Grid · Proven Since 1938
No water, no power, no fuss. Developed from the original Clivus Multrum and toughened up NZ-made. Urine diverts away at the throne while solids drop into one of four rotating compost bins - worms turn it into humus. Rotate every 3–4 months; empty once a year or two.
NZ-MADE · INDEPENDENTLY TESTED
Proven Results
Independently tested by the Rotorua Lakes Council Environmental Laboratory - our system cut effluent from 260,000 down to 10,000 PPM, comfortably inside NZ and Australian standards. Better results than a traditional septic tank, for less.
