What is one of the common sources of greywater?

• A. Kitchen sink water
• B. Shower water
• C. Lawn runoff
• D. Stormwater

Answer: (B)

Shower water is indeed one of the common sources of greywater. Greywater refers to slightly used water from sources such as sinks, showers, bathtubs, and washing machines. It typically does not contain serious contaminants and can be reused for irrigation or toilet flushing, making it a sustainable resource in water-efficient landscaping.

Kitchen sink water, while another source of greywater, often contains food particles and oils that can complicate its use in irrigation. Lawn runoff and stormwater are not classified as greywater; rather, they are considered runoff sources that can carry pollutants from the landscape to drainage systems. This distinction is important as it underscores the significance of understanding greywater management in promoting water efficiency. By utilizing shower water as a source of greywater, we can optimize water use and minimize waste.
