What is a Greywater Recycling System?
A greywater recycling system is a smart home solution that captures and reuses water from showers, sinks, and laundry (excluding toilets) for non-potable uses like flushing, gardening, and cleaning. As India faces water scarcity, this eco-tech is becoming a household essential.
Greywater systems offer a double win: reduce freshwater demand and cut your utility bill—all while living sustainably.
Why Greywater Matters in 2025
In 2025, India’s water crisis is no longer just a rural issue. Urban centers like Bengaluru, Chennai, and Delhi face seasonal shortages. A greywater recycling system can ease the pressure on municipal supply by turning waste into a resource.
The growing demand for eco-friendly plumbing and sustainable water use makes greywater recycling more relevant than ever.
How a Greywater Recycling System Works
- Collection: Water from bathroom sinks, showers, and washing machines
- Filtration: Removes soap, hair, and debris
- Storage: In above- or below-ground tanks
- Reuse: For flushing toilets, irrigating gardens, or floor cleaning
