In most areas of our country,the weather is very hot in summer , resulting in the need for regular watering the green belt.Usually,Watering one square meters of green belt takes about 5 seconds.According to the relevant standards,the water yield of household tap is 0.2L Per second,which means watering one square meters of green belt needs 1L water.The width of green belt in the city is usually one-meter-wide.Then,1km green belt needs 1000L water every day,nearly 1ton.Generally speaking,in every summer of China,there are at least three months which need for frequent watering every day(except the rain time).Therefore,only 1km green belt in the center of road needs 90 ton in 90 days.Add in other watering of green belt and cleaning of streets,the water consumption is very astonishing,which we should pay much attention to.
