What strategies will not reduce the use of potable water for irrigation?
A: Replacing permeable pavement with turf grass
B: Using stormwater for irrigation
C: Using graywater for irrigation
D: Installing native plants

参考答案: A

本题解释:
The installation of turf grass will increase the watering needs of the landscape.

Stormwater can be collected and used for irrigation if local codes allow it.

Graywater can be used in some jurisdictions for non-potable uses such as irrigation.

Graywater is defined by the Uniform Plumbing Code (UPS) as untreated house-hold wastewater which has not come into contact with toilet waste or kitchen sinks.

Graywater includes used water from bathtubs, showers, bathroom wash basins, and water from clothes-washer and laundry tubs. It does not include water from kitchen sinks or dishwashers.

Native plants require less irrigation, less fertilizer, and less maintenance than non-native plants. Native plants thus reduce the need for potable water use for landscaping, and reducing water use for landscaping in general. Native plants can be used to restore previously developed sites to increase open space.
