●Turn the tap off while you are brushing your teeth,washing your hands,doing dishes,taking a shower and so on.
●Catch the cold water that comes out of the tap or shower while you are waiting for the hot water.Use it to water plants or wash your toilet.
●Don't wash clothes too often.When you use the washing machine,make sure there is not only a pair of pants in it.
Outdoors:
●Water the garden and grass at night.This gives water more time to get into the earth without evaporation from the day's heat.
●Plant small trees under big trees.This will help stop evaporation and gives some shade(树阴) for your plants.You can also plant a shade garden under trees.
