What is 'greywater'?

Greywater refers to wastewater generated from domestic activities, such as bathing, laundry, cooking, and cleaning, that does not include toilet waste. This differentiates it from blackwater, which is water that has been contaminated by human waste, typically from toilets. Greywater can be reused for non-potable applications, such as irrigation or flushing toilets, which makes it valuable for water conservation efforts.

Understanding greywater is essential for managing community water systems effectively, as it represents a significant portion of residential wastewater that can be treated and reused, reducing overall water consumption and minimizing environmental impact. The ability to recycle greywater contributes to sustainable practices within water management systems.
