Greywater Reuse
A precise tool.
What is the Greywater Reuse & How does it work?
Greywater is the relatively clean wastewater generated from domestic activities such as bathing, laundry, and dishwashing. Reusing this water can significantly reduce the demand for fresh potable water, especially in arid regions.
The amount of greywater that can be safely reclaimed depends on capture efficiency, treatment performance, and the proportion of treated water that is actually reused for irrigation or toilet flushing.
By applying a simple mass‑balance calculation, homeowners and designers can estimate daily reusable volumes and annual water‑saving potential, supporting sustainable water management decisions.
Q_{reuse} = Q_{total} times frac{C_{capture}}{100} times frac{eta_{treatment}}{100} times frac{f_{reuse}}{100}
Q_{reuse} = daily reusable greywater volume (L)

Frequently Asked Questions
What is greywater?
Greywater is wastewater from household activities like bathing, laundry, and dishwashing.
How can I safely reuse greywater?
To safely reuse greywater, treat it to remove contaminants and use it for irrigation or toilet flushing.
What factors affect greywater reuse efficiency?
Capture efficiency, treatment performance, and the proportion of treated water reused all impact greywater reuse efficiency.
Can I reuse greywater for drinking?
No, greywater should not be used for drinking. It’s intended for non-potable uses like irrigation or toilet flushing.
What are the benefits of greywater reuse?
Greywater reuse reduces demand for fresh potable water and conserves resources, especially in arid regions.
How do I calculate the amount of greywater generated?
Calculate greywater by estimating the volume used in activities like bathing, laundry, and dishwashing.
What kind of treatment is needed for greywater reuse?
Basic filtration and disinfection are typically required to make greywater safe for non-potable uses.
