"Collected runoff" refers to water that is captured for irrigation reuse. This process involves collecting excess water from rainfall or irrigation systems that would otherwise flow away from the landscape, allowing it to be stored and utilized later for watering plants and maintaining the landscape. This not only conserves water but also promotes sustainable landscaping practices by making use of natural resources that might otherwise contribute to flooding or erosion.

Capturing runoff for reuse can help in managing water efficiently and reducing overall irrigation costs, which is increasingly important in regions facing water scarcity. This method contributes to sustainable practices by recycling water and reducing dependence on municipal water supplies.

The other choices relate to different concepts. Decorative fountains utilize water for aesthetic purposes but do not pertain to the idea of runoff being collected for reuse. Water that drains away from the soil does not imply any capture or reuse, as it indicates water loss rather than conservation. Polluted water would not be desirable for reuse due to health and ecological concerns, thus not aligning with the definition of "collected runoff" aimed at promoting positive water management strategies.
