What types of water should be used for irrigation?(choose 2)


A: Stormwater
B: Potable water
C: Blackwater
D: Graywater

参考答案: AD

本题解释:
A Stormwater can be collected in cisterns and used for irrigation purposes if local code allows it.
B Potable water usually comes from wells or municipal supplies and should not be used for irrigation. Onsite waste water treatment systems can turn stormwater, graywater, and blackwater into potable water as well.
C Blackwater is water from toilets or kitchen sinks that has not been treated.
D Graywater is water from laundry machines or showers that is not suitable for drinking, but can be used for other purposes such as irrigation and flushing toilets. Graywater is defined by the International Plumbing Code and Uniform Plumbing Code. Some states and local codes have differing definitions.
