Which water source is water from precipitation events that can be captured and reused for irrigation?

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

Answer: (D)

Rainwater is the water that falls as precipitation and can be captured at the source (like a roof catchment) and stored for later irrigation use. It’s a direct result of precipitation events and is commonly collected in tanks or cisterns, making it a renewable on-site water source for irrigation. Stormwater also comes from rain, but it refers to runoff that travels across surfaces and often requires treatment before reuse, whereas rainwater capture focuses on the water that initially precipitates and can be stored for irrigation with relatively simple systems. Gray water comes from domestic wastewater, and wells tap groundwater, not precipitation; thus rainwater best fits the description.
