What is greywater recycling?

Greywater recycling specifically refers to the practice of reusing lightly used water, which typically comes from sources such as sinks, showers, and washing machines, for non-potable applications. This involves treating and repurposing this water in a way that it can be safely used for activities like irrigation or toilet flushing, thereby conserving fresh water resources.

Lightly used water contains fewer contaminants compared to blackwater, which comes from toilets and has higher levels of pathogens and waste. By focusing on greywater, the process promotes sustainability, helps reduce the demand for potable water, and decreases the volume of wastewater that requires treatment. Thus, the correct choice clearly captures the essence of greywater recycling as it emphasizes the specific reuse of non-potable water for various practical purposes.
