Foss Toilets offer sustainable sanitation anywhere
The Foss toilet transforms wastewater into clean, reusable flushwater—all without a sewer or septic connection.
Perfect for off-grid and eco-friendly living, it’s a compact, energy-efficient solution designed to deliver reliable sanitation anywhere you need it.
Retrofit-ready, drop-in-place toilet and treatment system for any setting
Foss Toilets are designed for quick installation that seamlessly integrates into both existing and new builds in less than a day.
Our systems provide a reliable solution for any property type facing water challenges due to outdated or overburdened sanitation systems or evolving ecological standards.

Transforms waste to water
Our toilet treatment system handles and digests the toughest contaminants, while using evaporation and condensation to distill clean flushwater that’s reused over and over again.
1. Decomposition
In the blackwater unit, specialized microbes decompose hazardous biosolids as they would in healthy soil.
2. Evaporation & Condensation
Then, this treated blackwater is superheated into vapor, like clouds. The result is pure water from condensation, just like rain.

Safer, smarter water solutions for all of us
Good Health & Well-Being
Foss provides safe and affordable sanitation for remote and underserved communities without relying on any new public sewer infrastructure, closely aligning with UN Sustainable Development Goals 3,6, and 11.
Clean Water & Sanitation
1.4 million people die each year because of inadequate sanitation conditions. Access to only contaminated water makes keeping healthy personal hygiene impossible, even in hospitals. This causes widespread human suffering, the transmission of preventable diseases, and undue loss of life. Foss's decentralized, modular solution can bring safe water and sanitation sooner to places that need them.
Sustainable Cities & Communities
By scaling building by building, we can lay the foundation for a resilient and adaptable water care system that delivers clean water to those most in need. With decentralized, modular water treatment and reuse systems, we aim to create a “clean water ripple effect” where each installation leads to improving water access and health across entire communities.
