Every March 22nd is the World Water Day. The United Nations has decided that the theme of the World Water Day is “to protect the green mountains through the power of nature”. Talking about saving water, mention the toilets we go to every day. Domestic flushing toilets generally have problems such as large water consumption, difficult water control, serious aging and damage of facilities. Every day, large amount of water is drained away.
