What is a greywater system?

• A. A system that recycles relatively clean wastewater from sinks and showers for non-potable uses.
• B. A device that filters wastewater to drinking water.
• C. A network of pipes that diverts rainwater for landscaping only.
• D. A meter that tracks water usage.

Answer: (A)

Greywater systems collect wastewater from sources like sinks and showers that is relatively clean and reuse it for non-potable tasks such as watering landscapes or flushing toilets. This helps conserve potable water by putting lower-risk wastewater to beneficial uses, rather than sending it down the drain. It’s not treated to drinking standards and isn’t used for drinking; it remains separate from the potable supply. It’s also different from rainwater harvesting, which collects rain rather than household greywater. This description matches what a greywater system is.
