Which term refers to collecting and utilizing rainfall or runoff for use?

• A. Water Harvesting
• B. Potable Water
• C. Effluent Water
• D. Surface Water

Answer: (A)

Collecting rainfall and runoff for later use is the practice of water harvesting. This term specifically describes capturing precipitation from roofs, landscapes, or catchment areas, channeling it into storage, and then using that stored water for irrigation or other needs. It helps reduce dependence on potable supplies and increases resilience during dry periods. The other terms don’t fit because potable water describes water safe to drink, effluent water refers to treated wastewater, and surface water denotes water bodies like rivers and lakes themselves rather than the act of collecting and storing rainfall.
