Recently, the weather is dry and the company is short of water resources. Need to give a notice of about 120 words to ask employees to save water …

Take a shower with a shower nozzle: (1) Learn to adjust the ratio of hot and cold water. (2) Don't keep the water in the sprinkler open all the time, let alone open it. (3) Try to get wet from head to toe, then wipe the whole body with soap and rinse it for the last time. Don't wash your hair, upper body, lower body and feet alone. (4) Take a bath with concentration, hurry up, don't be idle, or wash while chatting. Don't have a big water fight with your good friends in the bathroom. Remember: time is water! (5) Don't take the opportunity of taking a bath to "wash clothes and shoes by the way". Take a bath in the bathtub. Be careful not to fill it with water. 1/3-? A basin is enough.

How to save toilet water

(1) If you think the water tank of the toilet is too big, you can put a brick or a coca-cola bottle filled with water vertically in the tank to reduce the amount of water flushed each time. However, it should be noted that bricks or coke bottles should not interfere with the movement of water tank components. (2) The water tank always leaks the most, and the water stop rubber is not tight, not only water. After the water is full, it flows away from the overflow hole; If the water stop rubber at the outlet is not tight, the water will keep flowing away and the water will keep entering the inlet pipe. (3) Using the collected domestic wastewater to flush the toilet, one water can be used for multiple purposes, saving clean water. (4) Regardless of the size and thickness of the garbage, it should be removed from the garbage passage and cannot be washed away with toilet water.

How to save water in washing machine

Washing clothes with a washing machine is labor-saving and convenient, but it also has some disadvantages, that is, it uses three-fifths more water than washing clothes by hand. How to save water as much as possible? You might as well insist on washing more than three clothes with the washing machine, and washing one or two small clothes by hand. In particular, we should insist on cleaning the foam first and then rinsing, so that the clothes will be clean after rinsing twice. Therefore, more than one third of water can be saved.

Do you have a good way to use more water?

(1) You can wash your feet and then flush the toilet. (2) A vat for collecting waste water should be prepared at home, which can completely guarantee the water needed for flushing the toilet. (3) Rice washing water and noodle cooking water are used to wash dishes and chopsticks, which not only removes oil but also saves water. (4) Raising fish and watering flowers can promote the growth of flowers and trees. At the beginning of the new millennium, the themes of "World Water Day" and "China Water Week" are "Sanitary Water Use" and "Strengthening Conservation and Protection to Realize Sustainable Utilization of Water Resources" respectively. Looking at this theme, we can't help but think of the famous aphorism: If we don't cherish the precious water resources, then the last drop of water on the earth is probably our tears!

Water resources, a "crisis" facing human society.

Water is one of the important resources for human survival and development, and it is an indispensable and irreplaceable special resource. Without water, there would be no life, no civilization progress, no economic development and no social stability. The water resources in the world are limited, so the economic and social development must adapt to the water supply, and the water cannot be used indefinitely or exceed the carrying capacity of water resources. In today's world, with the continuous growth of population and economic development, the demand for fresh water resources is increasing day by day; At the same time, due to unreasonable utilization, the shortage of fresh water resources is increasingly tense.

China has been short of water for a long time. Historically, China is a country with frequent droughts, known as "nine droughts in ten years". In the historical documents of more than 2200 years, there have been 1300 droughts. China's per capita water resources are only about 2,300 cubic meters, which is about a quarter of the world's per capita water. Water resources in China are not only less per capita, but also unevenly distributed. The basin area north of the Yangtze River accounts for 63.5% of the land area, while water resources account for 19% of the whole country. With the development of society and economy, the gap of water resources is getting bigger and bigger. At present, China's agricultural irrigation lacks more than 30 billion cubic meters of water every year on average, and there are still more than 30 million people in rural areas who have difficulty drinking water. There are more than 400 cities in China that are short of water, and there are more than 1 10 cities that are seriously short of water. The daily water shortage in Chinese cities is160,000 cubic meters, which affects the industrial output value by more than 200 billion yuan every year, and the urban population is about 40 million.

In addition to China, there are many countries and regions in the world with serious water shortage problems.

The United Nations Water Conference pointed out: "We are entering a new era of water shortage". The increasingly serious global water crisis has aroused great concern of the international community. 1972 United Nations Conference on Human Environment and 1977 United Nations Water Conference warned the world: "Water will soon become a serious social crisis, and the next crisis after the oil crisis is water." Countries all over the world have begun to pay unprecedented attention to water problems, and gradually formed a * * * understanding of water crisis. 1In August, 1995, the World Bank survey report announced that 26 countries, accounting for 40% of the world's population, were facing water crisis, and their agriculture, industry and people's health were seriously threatened; About 654.38 billion people in developing countries do not have access to clean water, 654.38 billion people do not have good sanitation facilities, 80% of diseases are caused by drinking unclean water, and 25 million people die every year. 1999 World Water Day, the United Nations warned that with the development of human production and the improvement of living standards, the world water consumption is increasing at an annual rate of 5%, and the total water consumption will double every 15 years. Unless governments take effective measures, before 2025, more than half of the population on earth will face the crisis of fresh water resources, and more than one third of the population will not be clean. The shortage of water resources has become the main restricting factor of global social and economic development. Rational utilization of water resources is an urgent task for sustainable development of human beings, and water saving is the key to rational utilization of water resources, and it is also one of the fastest, most feasible and most extensive ways to maintain sustainable utilization of water resources.

Saving water is an inevitable choice for sustainable development.

1992 170 heads of state and government put forward the strategy of sustainable development in the "2 1 Agenda Declaration" adopted at the Rio Conference on Environment and Development, pointing out that "water is not only necessary to maintain all life on earth, but also of vital significance to all social and economic sectors." China took the lead in formulating "China 2 1 Century Agenda", and explicitly included sustainable development as a national development strategy in the Ninth Five-Year Plan and the 20 10 development plan of national economy and society. Among them, water-saving work, as an important strategic decision of the CPC Central Committee and the State Council, has been included in the agenda of governments at all levels, and the concept of water-saving has been deeply rooted in people's hearts step by step.

? Saving water is an action to improve water utilization efficiency, reduce waste and coordinate the relationship between water resources and society, economy and environment. Therefore, in the process of water saving, we should proceed from China's water saving status, national conditions and water conditions. First, it is necessary to deeply analyze the current water-saving level and the water-saving effect produced by the current water-saving measures, analyze the existing problems, causes and difficulties in the work, and analyze the potential and breakthrough points of water-saving. On this basis, according to the needs and specific conditions of national economic and social development, regions, departments, industries and types are divided. Focusing on improving water use efficiency, this paper analyzes and puts forward the water-saving level that should be achieved in different stages and the engineering and non-engineering water-saving measures that should be taken, so as to realize the optimal matching and efficient utilization of water resources with water saving as the core, paying special attention to the comprehensive balance between water saving and open source, water saving and society, economy and environment, and ensuring the sustainable development of water resources and society, economy and environment.

The sustainable utilization of water resources is directly related to the implementation of China's sustainable development strategy. At present, there are some problems that can't be ignored in the process of shortage and unreasonable utilization of water resources in China: the interruption of northern rivers, represented by the lower reaches of the Yellow River, has intensified, resulting in the decline of river flood discharge capacity, the loss of industrial and agricultural production, the difficulty of drinking water for urban and rural residents, the serious destruction of ecological balance and the deterioration of ecological environment in estuary areas. Overexploitation of groundwater in some areas has affected urban and rural water supply, urban construction and people's survival. Due to the over-exploitation of groundwater in China, the funnel area has reached 87,000 square kilometers, and the water level in some funnel centers has reached 60-80 meters. The rapid growth of sewage and wastewater discharge has seriously damaged the comprehensive function of limited water bodies. Nearly 46.5% of major rivers and more than 90% of urban waters in China are polluted, of which 10% is seriously polluted, which has basically lost its use value and aggravated the shortage of water resources. In addition, there are 58 million poor people in China, mainly distributed in arid and water-deficient areas, who have long endured the threat of water shortage to their survival. 199 1 ~ 1996, there were 66,000 water disputes nationwide, and in the two years of 1997 and 1998, * * mediated water disputes 17400.

? The demand for water in the economic development of northern China shows an upward curve in the future development chart, and the implementation of the strategy of developing the western region is even more indispensable. It has become an inevitable choice for China's economic development to develop water resources rationally and save water.

Saving water is our common responsibility.

It can be said that through years of efforts, China has made great progress in water conservation, but compared with some developed countries, we still have a long way to go.

Agriculture is a big water user and a great waste of water resources. At present, the agricultural irrigation mode of "soil canal water conveyance plus flood irrigation" is still widely used in China. Half of the irrigation water is lost in the water conveyance, and the irrigation water utilization coefficient is mostly only 0.4, which is less than half of that of some developed countries. After irrigation with water per square meter, the grain yield in China increased by 0.5 kg, and that in developed countries could reach 2 kg. Industry, due to the backward technology of existing water facilities, the current water consumption per 10,000 yuan of industrial output value in China is 103 cubic meters, 8 cubic meters in the United States and only 6 cubic meters in Japan, which is 10 ~ 20 times that of developed countries; The reuse rate of industrial water in China is only about 40%, while the average level in developed countries is 75% ~ 85%. The phenomenon that urban residents don't talk about saving and waste domestic water is very serious, and water-saving education has a long way to go. Beijing alone leaks 360,000 tons of water every year. In Israel, which is also short of water, there are not only two sets of pipes for residents to flush toilets and wash their hands, but also two buttons for defecation. It was the Israelis with a strong sense of water crisis who invented the agricultural drip irrigation technology.

From now until the middle of the next century, China will fully realize the grand goal of socialist modernization. With population growth and socio-economic development, water consumption will increase substantially, and the contradiction between supply and demand of water resources will become more acute. It is predicted that the total water demand in 20 10 will be 698.8 billion cubic meters, in 2030 it will be 800 billion cubic meters, and in 2050 it will be at least 850 billion cubic meters, which will increase by 1995 respectively, so as to achieve a general balance between supply and demand of water resources in moderately dry years. It can be seen that the gap in water use is still quite large. Only by adhering to the principle of combining open source with throttling, putting throttling in the first place, further strengthening water conservation, realizing optimal allocation and efficient utilization of water resources centered on water conservation, and striving to achieve a basic balance between supply and demand, can the long-term economic development goal be successfully achieved.

Saving water and ensuring the sustainable utilization of water resources are our common cause and our common responsibility!

Saving water starts with me.

Establish the consciousness of cherishing water

For a long time, people generally believe that water is "inexhaustible". If you don't know how to cherish it, you will waste it. When we know that China's per capita water resources are abundant, the regional distribution is uneven, the year is unpredictable and the inter-annual difference is large. Coupled with pollution, water resources are more scarce, and tap water is actually difficult to come. Only by cherishing water and firmly establishing the belief that "saving water is glorious and wasting water is shameful" can we pay attention to saving water at all times.

form good habits

According to analysis, families can save about 70% water as long as they pay attention to getting rid of bad habits. There are many habits related to wasting water, such as: flushing cigarette butts and breaking garbage with the toilet; In order to receive a glass of cold water, a lot of water was put in vain; Wash potatoes and carrots before peeling, or wash them before choosing vegetables; Intermittent use of water (when opening the door to pick up guests, answering the phone, changing TV channels), with the faucet on; Forgot to turn off the faucet during the water stop; When washing hands, washing face and brushing teeth, let the water flow all the time; Do not check the faucet before going to bed or going out; The equipment leaked and was not repaired in time.

Use water-saving device

In addition to developing good water habits, it is very important and effective to use water-saving appliances in household water saving. Some people would rather let themselves go with the flow than change water-saving appliances. In fact, it is not cost-effective to pay so much water for a long time. There are many kinds of water-saving appliances, including water-saving water tanks, water-saving faucets and water-saving toilets. In principle, there are two types: mechanical (wrench and button) and automatic (electric, magnetic induction and infrared remote control).

Leak detection plug flow

It is no joke to "drip into a river" at home. Always check the tap water pipes in your home. In order to prevent a slight delay, don't ignore the leakage of faucet and water pipe connector. If you find water leakage, please ask someone or yourself to repair it in time to block the running water. For the water leakage that cannot be repaired for a while, it is best to temporarily control the water flow with the main gate at any time. Take good care of the faucet and unscrew the water gate of the faucet by half, then the leakage flow will naturally be small, and the water loss will be reduced by half at the same time.

Tips for saving water in laundry

(1) When the washing machine washes a small amount of clothes, the water level is set too high, and the clothes float around in high water without friction. Instead, it is not clean and wastes water. (2) Don't wash too little clothes. It is also a water-saving method to concentrate on washing after waiting too much. (3) If the rinsed water is left to the next batch of washing water, 30-40 liters of clean water can be saved at a time.

Water saving speech-

Student: You must have seen such a public service advertisement: there is a faucet on the TV screen, which is dripping with difficulty. The dripping speed became slower and slower, and finally the water was used up. Then a pair of eyes appeared on the picture, and a tear flowed out from it. Followed by this sentence: "If human beings don't cherish water, then the last drop of water we can see will be our own tears." Water is the source of life. If there were no water on the earth, Mother Earth would not give birth to our descendants. Because the earliest primitive life was first bred in the ocean and gradually extended to the land. Therefore, water is the cradle of life. The survival and development of human beings are also inseparable from water. Because we have to drink water every day, food growth can not be separated from water, and industrial production can not be separated from water. Water is also the "air conditioner" of nature. How happy it would be to have a rain in the hot summer when people feel unbearable heat! Walking by the sea, the sea breeze blows gently, sweeping away the hot and irritable mood; When the cold winter comes, the seawater continuously transfers the stored heat to the surrounding land ... all these are the functions of water.

Is water really not worth it? Is it really unimportant to save water? 93% of the water in the world is salty and can't be drunk. Fresh water accounts for only 7%, and drinking water accounts for only 0.8%. The world's 5 billion people depend on drinking this 0.8% fresh water. Look, how precious water is! Although China is rich in water resources, there are few available fresh water resources, and with the development of industry, water pollution has become a serious problem, and many industrial wastewater stinks. What a terrible thing! For example, the water consumption for a picnic. March 22nd is World Water Day. Every year on this day, all countries in the world will publicize that everyone should cherish water resources and protect the water of life. In fact, it is not only this day, but every day in our life should cherish every drop of water and cherish the water of life with practical actions! Water exists in the sky, underground, rivers and lakes. For saving water, students always feel less important than saving other things. Some students turn on the tap, wash their feet and wash their children. Some students don't drink boiled water, but drink tap water with their mouths to the faucet. The sound of water doesn't hurt at all.

Although three liters of water per person per day can sustain life, in fact, every urban resident has to cook, wash clothes and wash vegetables every day ... everything can't be separated from boiling water, and it takes hundreds of liters of water. In addition, agriculture and industrial production are inseparable from water. For example, steelmaking and steel rolling only need water cooling; In order to maintain a certain temperature and humidity, the textile workshop needs to adjust the moisture; Building construction is inseparable from water; Paper-making, power generation ... Food, clothing, housing and transportation, which can be separated from boiling water? People can live without food for several days, but they can't live without water for several days. Humans can't live without water, which shows how important it is to save water.

Students, we are small masters of the country, and we should develop good ideas and habits of saving water from an early age. Whether at school or outside school, we should pay attention to saving water. We should be a good boy who saves water by taking practical actions.

People can live without food for several days, but they can't live without water for several days. Humans can't live without water, which shows how important it is to save water.

Then how do we get the tap water we use every day? It is the worker's uncle in the waterworks who introduces river water or groundwater into the factory, puts the water into the sedimentation tank, adds medicine for disinfection and sterilization, and removes harmful substances and impurities. In this way, many pipelines were buried underground. These pipes are tied up one by one, which is the result of the hard work of many waterworks workers and uncles day and night. When we turn on the tap, we should think that the bread in the water contains the hard work of many workers' uncles!

Students, do you know the meaning of saving water? Please look at an account: one ton of water can supply about 150 kg of steel, generate electricity 1000 kg per hour, produce 500 kg of chemical fertilizer, weave 220 meters of cloth and grind 34 bags of flour. "Dripping water becomes a river", if everyone saves water, every little makes a mickle, they can play a greater role!
