Which term denotes water resulting from precipitation that is collected for reuse?

• A. Rainwater
• B. Quality of Water Supply
• C. Blowdown
• D. Stormwater

Answer: (D)

The main idea here is recognizing the term used for water from precipitation that is captured and stored for reuse. When rain falls and that water is gathered through collection systems (like rooftops, storm drains, or surface runoff) and then reused for irrigation, it is referred to as stormwater. This term emphasizes the water’s origin in precipitation and its management as a resource through capture and reuse.

This concept matters in irrigation design because capturing stormwater reduces reliance on other water supplies and helps manage runoff that would otherwise leave the site. It’s distinct from blowdown, which is the deliberate discharge from a system to control mineral buildup and water quality, and from general statements about the water supply quality, which aren’t specific terms for the collected precipitation itself. While rainwater describes the water that precipitates, stormwater specifically highlights the water captured for reuse after precipitation.
