Which practice helps prevent irrigation water waste on impervious surfaces?

• A. Rely solely on rainfall to meet plant needs
• B. Water during hottest part of the day
• C. Align spray patterns to avoid sidewalks/buildings, use efficient nozzles, and water during cooler times; consider mulch and soil moisture monitoring
• D. Increase spray patterns to sidewalks to clean pavement

Answer: (D)

The main idea here is irrigation efficiency: keep water where it’s needed and avoid wasting it on surfaces that don’t benefit from it. To prevent irrigation water waste on impervious surfaces, you should direct spray patterns away from sidewalks, buildings, and driveways, and use efficient nozzles that apply water precisely to the landscape. Watering during cooler times helps reduce evaporation and runoff, so more water actually soaks into the soil where plants need it. Adding mulch helps conserve soil moisture and slows evaporation, while soil moisture monitoring ensures you don’t overwater. Watering during the hottest part of the day wastes water through rapid evaporation and can cause unnecessary runoff onto impervious surfaces. Spraying toward sidewalks to “clean” pavement uses water that isn’t helping the plants and can contribute to environmental runoff. The combination of targeting the landscape, using efficient equipment, watering at cooler times, and monitoring moisture is the best approach to minimize waste.
