Home gray water reclamation
Cut your water use in half.
Greenwater's gray water system diverts shower and sink water back to your garden — no full replumbing, no maintenance, no guilt. Just 25,000 gallons saved every year.
How it works
Smart diversion,
not full replumbing.
Intelligent Diversion
Our valve pack reads source quality in real-time and diverts only reclaimable gray water (greywater) from showers and sinks. Black water lines stay untouched — reducing permitting friction to near zero.
3-Stage Filtration
Sensor-driven AI models continuously optimize a three-stage filtration process, ensuring every drop meets quality thresholds before reaching your garden.

FAQ
Common questions
A gray water system (also spelled greywater system) diverts household wastewater from showers, sinks, and laundry — water that has been used but is not contaminated with sewage — and recycles it for garden irrigation. Greenwater automates this with AI-driven filtration, so every diverted drop meets quality standards before reaching your plants.
Greenwater is engineered with safety as the first concern. Water passes through multiple filtration systems and is purified from microbial contaminants. Every system is built with redundancies and tested far beyond normal operating conditions.
Every component is engineered for tens of thousands of duty cycles. The system doesn't need any maintenance — ever.
Yes. Gray water (greywater) has been proven safe for gardens, with no adverse effects compared to tap water. Our filtration exceeds regulatory requirements.
A typical install takes less than a day. We connect to existing drain lines without modifying your plumbing stack — no permits required in most jurisdictions.
Greenwater is currently available through a limited pilot program. Reach out to our team to learn about pilot pricing and availability in your area.
Gray water (greywater) is wastewater from showers, bathroom sinks, and laundry — it does not contain sewage. Black water comes from toilets and contains human waste. Greenwater only diverts gray water lines; black water lines are never touched.
