OCTO: Off-Grid Sanitation Reinvented

Introducing OCTO, the next-generation, fully autonomous off-grid sanitation solution. Engineered to operate independently of water, sewer and power connections, OCTO integrates a patented membrane bioreactor with solar power to deliver clean, comfortable sanitation in locations where conventional infrastructure simply cannot reach.

Our mission is to provide clean, hygienic and dignified sanitation for communities around the world, by transforming human waste into a resource through a circular treatment loop that is safe, scalable and self-contained.

Key Features of OCTO

Designed for performance, sustainability, and autonomy, OCTO combines cutting-edge engineering with real-world usability.

OCTO / Anatomy OCTO single-cabin product render
01

True Off-Grid Operation

Requires no water, sewer or grid power connections. A solar canopy keeps the unit running autonomously for up to six months between services.

02

Built-in Wastewater Treatment

A patented membrane bioreactor (MBR) treats organic wastewater on-board, removing contaminants and producing safe, reusable greywater.

03

Water Recycling Inside the Unit

Recovered greywater is reused for toilet flushing and handwashing, cutting fresh water demand and closing the sanitation loop on-site.

04

Comfortable, Dignified Interior

Daylit, ventilated cabin with hygienic surfaces, modern fittings and a layout designed for long-stay comfort, not just survival use.

05

Compact, Yet High Capacity

A single cabin handles 100 to 150 daily uses with a small footprint, ideal for high-traffic sites with limited space.

06

Smart Remote Monitoring

Built-in connectivity provides remote diagnostics, usage data and service alerts, so operators can intervene before performance is affected.
