A Greywater filtration system
The Estuary.
This compact water recycler reduces utility costs and, when paired with a waterless toilet, replaces septic and closes the loop with nature-powered water reuse.
Innovation backed by nature.
The Estuary combines advanced engineering with natural water cycles, creating a durable, sustainable water system for long-term use. Every element is designed to last—offering dependable performance backed by remote monitoring and a dedicated service team to ensure your experience is always maintenance free.
- Recycles up to 135 gallons per day
- Low energy use
- Ultra-quiet
How it works
First, lightly used greywater from laundry, sinks, baths, and showers is collected for treatment. Then, in the Smart Bench and Treatment Planter, plants and microbes absorb and break down contaminants, cleaning the water for reuse. Finally, cleaned water is ready for non-potable reuse in toilet flushing, irrigation, and other select applications.
