Greywater is the wastewater generated from household activities like showering, washing clothes, and dishwashing. It is different from blackwater (toilet wastewater) in that it doesn't contain hazardous human waste. Greywater is often considered a valuable resource that can be reused for non-potable purposes such as landscape irrigation, toilet flushing, and floor cleaning.
Greywater can be used in sustainable architecture by installing a greywater treatment system that recycles the wastewater and diverts it for reuse. These systems typically include filtration, disinfection, and storage components that can be integrated into the building design. By using greywater, sustainable buildings reduce their demand for potable water, which in turn lowers the energy and chemicals needed for water treatment and distribution. Reusing greywater also reduces the amount of wastewater that needs to be treated and discharged into the environment, leading to a smaller environmental footprint.
