What is graywater primarily used for in LEED’s water management practices?

• A. Irrigation and non-potable applications
• B. Potable water needs
• C. Drinking water supplies
• D. Cooling systems

Answer: (A)

Graywater is primarily utilized in LEED’s water management practices for irrigation and non-potable applications. This focus stems from the intention to conserve potable water by reusing wastewater generated from activities such as bathing, laundry, and dishwashing. By redirecting graywater for purposes such as landscape irrigation, toilets, and other non-drinking applications, buildings can significantly reduce their overall water consumption and contribute to sustainable water management. In contrast, potable water needs and drinking water supplies pertain to clean, drinkable water, which graywater is not suitable for, as it may contain contaminants that require treatment before it can be consumed. Similarly, while graywater can theoretically be used in cooling systems, specific regulations and practical limitations often restrict its application in such contexts. Therefore, the primary focus on graywater within LEED's framework is its role in reducing the demand for potable water through its use in irrigation and non-potable applications, supporting broader sustainability and water efficiency goals.
