Which of the following is NOT one of the three wastewater types produced at a building?

• A. Gray Water
• B. Blackwater
• C. Storm Water
• D. Reclaimed Water

Answer: (D)

The on-site wastewater streams you deal with in a building are typically gray water, blackwater, and stormwater. Gray water comes from sinks, showers, and laundry (not toilets); blackwater is wastewater from toilets; and stormwater is precipitation that runs off roofs and surfaces. Reclaimed water, however, is treated wastewater that’s intended for reuse (like irrigation or toilet flushing) and isn’t a wastewater produced directly by the building. So reclaimed water isn’t one of the three wastewater types generated on-site, making it the correct choice for NOT being produced as wastewater by a building.
