Which term refers to wastewater from domestic sources that is commonly reused for irrigation after treatment?

• A. Reclaimed Water
• B. Stormwater
• C. Wells
• D. Gray Water

Answer: (D)

The concept here is how wastewater is classified for reuse. When household wastewater is treated to a standard suitable for non-potable uses like irrigation, the water is called reclaimed water. It’s treated at a facility to meet regulatory quality levels and is often distributed through a dedicated non-potable system to irrigation sites, ensuring safety and consistency for public health and the environment.

Gray water, on the other hand, comes from everyday domestic activities such as showers, sinks, and laundry and is typically reused on-site with lighter treatment or simple filtering. It is not the same as reclaimed water in terms of the level of treatment and the scale of reuse.

Stormwater is rainfall runoff, and wells refer to groundwater sources, not a wastewater reuse category.

So, the term that fits the description of wastewater from domestic sources that is commonly reused for irrigation after treatment is reclaimed water.
