Frequently Asked Questions
Do these systems really re-use every flush?
Yes, every flush is reused.
How is this system different from a typical greywater or blackwater system?
Unlike typical greywater and blackwater systems, which either occupy significant space or require off-site treatment, Foss systems treat both greywater and blackwater on-site using a unique combination of biological digestion and distillation.
Our compact design fits within the building itself and employs a divide and conquer approach. The blackwater treatment component handles the most concentrated contaminants before directing the effluent into the greywater system, which filters all of the water in the system. By handling the toughest contaminants upfront and treating filter backflushes, the greywater filters last longer and run with exceptional energy efficiency.
Can Foss systems be installed in areas without sewer access?
The Foss water system is a self-contained system that treats and recycles domestic wastewater, converting waste blackwater and greywater to clean, reusable water that can water lawns, run appliances, and flush toilets amongst other non-potable uses. This means the Foss water care system only needs to be connected to electricity, without needing a sewer connection or a septic leach field.
How easy is it to retrofit my existing plumbing to include a Foss care water system?
Retrofitting your existing plumbing to include a Foss water care system is quick and straightforward. Our systems are designed for drop-in-place installation with minimal disruption, usually completed in less than a day.
Whether you’re upgrading an older home, a multi-family property, or a commercial building, our compact system integrates seamlessly into your current setup without requiring extensive plumbing changes.
What makes Foss water systems a better alternative to traditional septic systems?
Foss water care systems are a modern alternative to traditional septic systems, offering several key advantages. Unlike septic systems that require large leach fields and can struggle with capacity issues, especially in areas with poor soil or limited space, Foss systems are compact and fit within the building.
They treat both greywater and blackwater on-site, producing clean, stormwater-quality effluent. There’s no septic tank to be emptied, just a biosolid brick that only needs to be disposed of once or twice a year.
How is this system different from compost toilets?
Compost toilets require ongoing maintenance, such as adding sawdust, frequent turning, and regular emptying of the compost, which can pose significant health risks if not managed correctly. Short-term and long-term eco rentals often face this challenge with educating guests.
In contrast, Foss water care systems use advanced biological digestion to break down waste automatically and produce clean water without the need for manual intervention. Foss systems are also better suited for higher occupancy buildings, where compost toilets would struggle to manage the volume.
How much space does a Foss water care system require?
Foss water care systems are compact and designed to fit within the footprint of the building they serve.
Whether for a single-family home or a multi-story commercial property, the system can be easily integrated without taking up valuable land space, making it a space-efficient alternative to traditional septic systems or large greywater setups.
What stage of development are Foss water systems currently in?
Foss water care systems are currently in the pilot testing phase with real-world installations. We’re working closely with industry partners and regulatory bodies to achieve permitting and certifications, including NSF-350 for residential water reuse systems.
As we continue refining the technology, we’re actively seeking new opportunities for early adoption, especially in regions facing water infrastructure challenges including the states of Washington, California, or Hawaii. Contact us here.
