What is meant by 'graywater reuse'?

Graywater reuse refers specifically to the practice of recycling water that comes from non-toilet sources, such as sinks, showers, bathtubs, and washing machines, for purposes like irrigation and other non-potable uses. This process helps to conserve fresh water by repurposing water that would otherwise go to waste. Given the pressing global water scarcity issues, graywater reuse is becoming an increasingly important practice for sustainable water management.

This approach not only reduces the demand on freshwater resources but also minimizes the volume of wastewater that needs to be treated and disposed of, contributing to a more sustainable water cycle within communities.
