Which of the following strategies will not reduce the use of potable water for irrigation?

The strategy of replacing permeable pavement with turf grass will not reduce the use of potable water for irrigation because turf grass typically requires a significant amount of water to maintain healthy growth, especially in regions that experience dry spells or lack sufficient rainfall. In contrast, permeable pavements facilitate water infiltration and can help reduce the need for irrigation by allowing rainwater to percolate through the ground, replenishing groundwater and promoting the health of surrounding vegetation without the need for additional water sources.

On the other hand, installing native plants, using rainwater, and utilizing gray water for irrigation are all effective strategies for reducing the consumption of potable water. Native plants are adapted to local climates, often requiring less water than non-native plants, which can further conserve water resources. Using rainwater for irrigation captures precipitation, making it a sustainable alternative to municipal water supply. Similarly, gray water systems recycle water from sinks, showers, and washing machines, significantly decreasing the dependency on potable water for irrigation purposes.
