Wastewater created at a building is subdivided into three types, what are those types?

• A. Gray Water, Black Water, Storm Water
• B. Gray Water, Black Water, Reclaimed Water
• C. Gray Water, Storm Water, Reclaimed Water
• D. Black Water, Storm Water, Reclaimed Water

Answer: (A)

The main concept here is how wastewater from a building is categorized by source and contamination into three types: gray water, black water, and storm water. Gray water comes from sinks, showers, bathtubs, and laundry—wastewater that does not contain toilet waste. Black water is sewage from toilets and contains human waste. Storm water is runoff from precipitation, such as rain or melted snow, that flows off roofs, pavement, and other surfaces. These distinctions matter for how the water is handled, treated, and possibly reused. Reclaimed water, which appears in some options, is treated wastewater intended for reuse and is not considered one of the basic building-generated wastewater types.
