Information on saving water

Water conservation refers to strengthening water management through administrative, technical, economic and other management means, adjusting water use structure, improving water use technology, implementing planned water use, eliminating water waste, and using advanced science and technology to establish scientific water use system, effectively use water resources, protect water resources, and adapt to the needs of sustainable development of urban economy and urban construction. Here, the meaning of water conservation has exceeded the meaning of water conservation. It includes the protection, control and development of water resources (surface water and underground water), and ensuring the rational and economic utilization of the maximum amount of water available, as well as careful management and civilization. The use of natural resources. It also includes a series of administrative measures such as relevant legislation, water prices, and management systems.

We have been taught to save water since childhood, but do you know how to do this in daily life? Here are some methods:

1. When washing dishes by hand, do not leave the faucet on during rinsing. You should put dishwashing water in one basin and old water in another basin.

2. Only run your dishwasher when it is full, which can save you 1,000 gallons of water per month.

3. Check your water meter and record your water usage.

4. Use a partially filled basin or sink to wash things instead of using running water directly from the faucet.

5. Use the water you use to wash things to water the plants you grow at home.

6. Install a water-saving toilet.

7. Designate a cup to drink from every day, which will reduce the need for scrubbing.

8. Teach your children to tighten the faucet after using water.

9. When washing clothes, set the water level just right for the amount of clothes you have.

10. When you're drying your pots and pans, leave the faucet running and soak them.

11. Use recycled water from commercial car washes to wash your car.

12. When you brush your teeth, turn off the faucet.

13. Encourage your school and local government to help develop and promote water conservation concepts among the population.

14. Use a broom instead of a hose to clean your driveway, sidewalk, or other areas of your home.

15. Find a place where your pet needs water to bathe outdoors, such as a lawn or under a big tree.

Water price policy is a means to protect water resources and save water. It can restrict users' water consumption to a certain extent, especially for industrial water. Facts have proven that low water prices are one of the reasons for wasting water. Experts point out that a 10% increase in water prices will reduce household water consumption by 3%-7%.

Water is the source of life

Beijing Water Conservation Measures were implemented in May 2005

The municipal water conservation management department shall, in conjunction with the municipal quality supervision and inspection administrative department, confirm the "List of Water-Saving Water Appliances" and the "List of Water-Saving Appliances that Are Directly Obsolete" and announce them to the public

Water Saving in Bathing

Use a nozzle to take a shower: (1) Learn to adjust the ratio of hot and cold water. (2) Do not leave the water on the nozzle all the time, let alone leave it open. (3) Get wet from head to toe as much as possible, then apply soap and scrub the whole body, and rinse thoroughly for the last time. Do not wash your hair, upper body, lower body and feet separately. (4) When taking a bath, you must concentrate on taking a shower and take your time. Do not take it leisurely or chat while washing. Don't even have a big fight with your best friends in the bathroom. Remember: time is water! (5) Do not use the opportunity of taking a bath to wash clothes and shoes "by the way". When taking a bath in the bathtub, be careful not to fill it with water. A 1/3-? basin is enough.

Water Saving in Toilet

(1) If you think the toilet water tank is too big, you can put a brick or a large Coke bottle filled with water upright in the water tank to reduce water consumption. Amount of water for each flush. However, be careful not to place bricks or Coke bottles that impede the movement of water tank components. (2) The water tank always leaks the most. If the water inlet sealing rubber is not tight, the water will not stop filling. When the water is full, it will flow away from the overflow hole; if the water outlet water sealing rubber is not tight, the water will continue to flow away and the water inlet pipe will not stop. Water enters the ground. (3) Use collected household wastewater to flush toilets, which can be used for multiple purposes and save clean water. (4) Regardless of size or thickness, garbage should be removed from the garbage channel and should not be flushed with water from the toilet.

Tips to solve leaking toilets

In the past, the bucket in my toilet often leaked.

I came up with a simple and easy way, and after using it for almost a year, I have basically solved the leakage problem. The main reason why the water tank leaks is that the copper wire used to connect the handle to the leather bowl is often stuck, preventing the leather bowl from falling. If the leather bowl cannot be lowered, it cannot completely block the leakage, leading to water leakage. You can twist a plastic belt into a plastic string, pass the plastic string through the iron ring on the leather bowl, pick up both ends and connect it to the handle rocker. The plastic rope is strong and not afraid of blisters, so it needs to be replaced every six months. Users with leaky water tanks may wish to give it a try.

How to save water in a washing machine

Washing clothes in a washing machine is labor-saving and convenient, but it also has a shortcoming, that is, it uses three-fifths more water than washing by hand. How to save water as much as possible? You may wish to insist on washing more than three pieces of clothing in the washing machine, and insist on washing one or two small items by hand. In particular, you must insist on shaking off the foam first and then rinsing, so that the clothes will be clean after rinsing them twice. As a result, more than one-third of water can be saved.

One water for multiple uses

(1) After using the face wash water, you can wash your feet and then flush the toilet. (2) A large bucket for collecting waste water should be prepared at home, which can fully guarantee the amount of water required for flushing the toilet. (3) Rice washing water and water used to cook noodles can be used to wash dishes and chopsticks to remove oil and save water. (4) The water used for fish farming can promote the growth of flowers and trees.

Washing tableware to save water. When washing tableware at home, it is best to wipe off the oil stains on the tableware with paper, then wash it with hot water, and finally rinse it with more warm or cold water.

Toys are children’s close partners. However, some toys (such as water spray guns) consume a lot of water and are not worth recommending, especially in areas where water resources are scarce. There were also some naughty teenagers who had a water fight with each other under the faucet of the tap water. The water splashed everywhere and they were very happy. Unknowingly, the clean ground got wet, and the passers-by were scared to avoid the large amount of water. Also wasted. How bad!

In winter in the north, water pipes are easy to freeze and crack, causing serious water leaks. Special attention should be paid to prevention and inspection. For example, (1) the covering sand washed away by floods in the rainy season must be filled before winter to prevent the shallow soil from freezing and damaging the water pipes. (2) Antifreeze equipment (antifreeze plugs, antifreeze wooden boxes, etc.) must be installed on faucets and water pipes outside the house. (3) If there are icy areas in the house, they should also be wrapped in torn sacks and wrapped with straw ropes. (4) For houses with water pipes, seal the cracks in doors and windows, and pay attention to thermal insulation inside the house. (5) Once the water pipes are frozen, do not use fire or boiling water (this will cause water pipes and faucets to be damaged due to sudden expansion). You should wrap the faucets with hot towels to help thaw them.

Household water records

As the saying goes, writing diligently saves thinking. If you record the readings of your home water meter at a regular time every day (at a fixed time in the morning or evening), there will be many benefits. (1) The water consumption per day, month, and year can be easily calculated, and paying water bills is no longer blind. (2) Since the water consumption situation has been recorded, you can see whether there is any waste, and you will know where to start saving water. (3) It is not very difficult to write down one note every day, but it is not very difficult to do it every day for several months or several years, which is a moderate test of perseverance, perseverance, patience and carefulness. (4) Write down this running account to see changes in water consumption. What is the relationship between this change and factors such as temperature, cloudiness, dryness and humidity? Is it related to changes in family living standards (purchasing electric fans, refrigerators, air conditioners, changes in eating habits, etc.)? Who says this is not scientific research?

Flow rate is the amount of water flowing out (flowing through) per unit time (such as 1 second). Measuring the flow of tap water at home is the same as measuring the flow of the Yangtze River, but the methods are different. First prepare a regular bucket and calculate its volume (for example, 18.6 liters); then prepare a stopwatch, an ordinary watch will do. When measuring, first open the faucet to the maximum extent and wait for the water flow to balance. When the bucket is full, stop the timing and read the duration (for example, 23.4 seconds); the measured flow value is the volume divided by the duration, that is 18.6/23.4=0.795 liters/second. For the sake of reliability, measure three times and take the average of the three results. If a water meter is installed in your home, you can know the amount of water passing through the meter by reading it, making it easier to measure the flow.

Water-saving experiment

When you think of a water-saving method, it will be interesting to do an experiment yourself. For example, if you put bricks in the toilet water tank, you can know the changes in primary water consumption by measuring the flow.

From household water use records, we can also see the changes in water consumption in a day and a month, and we can roughly estimate the amount of change.

Water Saving Propaganda

Everyone has a responsibility to save water. Only when everyone pays attention to water conservation can water scarcity be far away from us, life will be stable and harmonious, and the environment will be beautiful and comfortable. After we young people understand these principles, we must not only practice it ourselves, but also do a good job in publicity work, tell our relatives and friends, and let everyone save water. This is what we can do to contribute to society.

Saving water is our common responsibility

At the beginning of the millennium, the themes of "World Water Day" and "China Water Week" are "Sanitary Water" and "Strengthening Conservation" respectively. and protection to achieve sustainable utilization of water resources.” Looking at such a theme, we can't help but think of the cautionary saying: If we don't cherish precious water resources, then the last drop of water on the earth is likely to be our tears!

Water resources, the common "crisis" faced by human society

Water is one of the important resources on which human beings depend for survival and development. It is an indispensable and irreplaceable special resource. resource. Without water, there would be no life, no progress of civilization, no economic development and no social stability. The world's water resources are limited, and economic and social development must be adapted to the water supply. Water cannot be collected and used without limit, and the carrying capacity of water resources cannot be exceeded. In today's world, with the continuous growth of population and economic development, the demand for freshwater resources is increasing; at the same time, due to unreasonable utilization, the originally scarce freshwater resources are becoming increasingly tense.

my country has been short of water resources for a long time. Historically, my country is a country with frequent droughts, known as "nine droughts in ten years". In more than 2,200 years of historical records, major droughts have occurred as many as 1,300 times. my country's per capita water resources are only about 2,300 cubic meters, which is about a quarter of the world's per capita water. Not only does my country have a small amount of water resources per capita, but the distribution of water resources is extremely uneven. The drainage area of ??the water system north of the Yangtze River accounts for 63.5% of the land area, but the water resources account for 19% of the country. With the development of my country's society and economy, the water gap is getting bigger and bigger. At present, my country's agricultural irrigation lacks an average of more than 30 billion cubic meters of water every year, and more than 30 million people in rural areas across the country have difficulty drinking water. More than 400 cities across the country are short of water, and more than 110 cities have serious water shortages. The daily water shortage in cities across the country is 16 million cubic meters. Every year, water shortage affects the industrial output value of more than 200 billion yuan and affects the urban population of about 40 million. people. In addition to my country, there are many countries and regions in the world that have serious water shortage problems. The United Nations Water Resources Conference pointed out: "We are entering a new era of water scarcity." The growing global water crisis has attracted great attention from the international community. The 1972 United Nations Conference on the Human Environment and the 1977 United Nations Water Conference warned the world: "Water will soon become a serious social crisis, and the oil crisis will The next crisis after that is water. "Countries around the world have begun to pay unprecedented attention to water issues and are gradually developing a comprehensive understanding of water resources crises. In August 1995, the World Bank survey and statistics report was released: 26 countries, accounting for 40% of the world's population, are facing water crises. The agriculture, industry and people's health in these countries are seriously threatened; about 1 billion people in developing countries cannot drink water. To clean water, 1.7 billion people do not have good sanitation facilities, 80% of diseases are caused by drinking unclean water, and 25 million people die every year. On World Water Day in 1999, the United Nations issued a warning that with the development of human production and the improvement of living standards, the world's water consumption is increasing at a rate of 5% per year, and the total water consumption will double every 15 years, unless governments of various countries Take effective measures, otherwise, before 2025, more than half of the world's population will face a freshwater resource crisis, and more than one-third of the population will not have access to clean drinking water. The shortage of water resources has become a major constraint on today's global social and economic development. The rational use of water resources is a top priority for sustainable development of mankind, and water conservation is the key to the rational use of water resources. It is one of the fastest, most feasible, most extensive and effective ways to maintain the sustainable use of water resources.

Water conservation is an inevitable choice for sustainable development. In 1992, 170 heads of state and government adopted the "Agenda 21" declaration at the Rio Conference on Environment and Development, proposing a sustainable development strategy and stating that "water Not only is it necessary to maintain all life on earth, but it is also of vital importance to all social and economic sectors. "my country took the lead in formulating the "China Agenda 21" and clearly included sustainable development as a national development strategy in the "National Development and Reform Commission". Economic and Social Ninth Five-Year Development Plan and 2010 Development Plan. Among them, as a major strategic decision of the Party Central Committee and the State Council, water conservation has been included in the work agenda of governments at all levels, and the concept of water conservation is gradually gaining popularity. 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 must start from the current water saving status, national conditions and water conditions in our country. First, we must conduct an in-depth analysis and grasp the current level of water saving and the water saving effect of current water saving measures, and analyze the current water saving Existing problems, their causes and work difficulties, and analyze water-saving potential and breakthrough points. On this basis, we should divide regions, departments, industries, and types according to the needs of national economic and social development and specific conditions. Focusing on improving water utilization efficiency, we analyze and propose the water-saving levels to be achieved at different stages and the engineering and non-engineering water-saving measures to be taken to achieve optimal supporting and efficient utilization of water resources centered on water conservation, and special attention should be paid to water conservation. Water and open source, water conservation and the overall balance of society, economy and environment ensure the sustainable development of water resources, society, economy and environment. Whether water resources can be used sustainably is directly related to the implementation of my country's sustainable development strategy. The current shortage of water resources and some problems arising from irrational utilization in our country cannot be ignored: the intensification of river drying in the north, typically represented by the lower reaches of the Yellow River, has led to a decrease in river drainage capacity, resulting in losses to industrial and agricultural production. Urban and rural residents have difficulty drinking water, which has seriously damaged the ecological balance and worsened the ecology and environment of the estuary area. The massive overexploitation of groundwater in some areas has affected urban and rural water supply, urban construction and people's survival in these areas. Due to over-exploitation of groundwater across the country, the area of ??funnels has reached 87,000 square kilometers, and the water level in the center of some funnels has reached a depth of 60 to 80 meters. The rapid growth of sewage discharge has seriously damaged the comprehensive functions of limited water bodies. Nearly 46.5% of the country's major river sections and more than 90% of urban waters are polluted. Among them, 10% of the river sections are seriously polluted and have basically lost their capacity. Use value has aggravated the shortage of water resources. In addition, there are still 58 million poor people in our country, mainly located in arid and water-scarce areas, who have long endured the threat of water shortage to their survival. From 1991 to 1996, 66,000 water disputes occurred in governments across the country, and in 1997 and 1998, 17,400 water disputes were mediated and handled by the government. The demand for water used in the development of northern my country's economy will show an upward curve in the future development map. The implementation of the western development strategy is indispensable for water. Rational development of water resources and water conservation have become inevitable choices for my country's economic development.

Saving water is our common responsibility. It can be said that through years of hard work, my country's water conservation industry has made great progress and development. However, compared with some developed countries, we still have some shortcomings. distance. Agriculture is a large user of water resources and a large waste of water resources. In our country, the agricultural irrigation method of "earth canal water delivery and flood irrigation" is still widely used. Half of the irrigation water is lost through leakage during water delivery. The utilization coefficient of irrigation water is mostly only 0.4, which is lower than that of some developed countries. half level. In my country, the grain yield increased by 0.5 kilograms per square meter of water irrigation, while in developed countries it can reach 2 kilograms. In industry, due to the backward technology of existing water facilities, my country's current industrial water consumption per 10,000 yuan of output value is 103 cubic meters, compared with 8 cubic meters in the United States and only 6 cubic meters in Japan, which is 10 to 20 times that of developed countries; reuse of industrial water in my country The rate is only about 40%, while the average in developed countries is 75% to 85%. The problem of urban residents not saving water and being extravagant and wasteful is very serious. Water-saving education has a long way to go. In Beijing alone, 360,000 tons of water escape and leak every year. Israel, which is also short of water, not only has two sets of pipes for flushing toilets and washing hands, but also has two buttons for toilet flushing and urination.

It was the Israelis who had a strong awareness of water concerns who invented the agricultural drip irrigation technology. From now to the middle of the next century, it is the period when our country will fully realize the grand goal of socialist modernization. With population growth and socioeconomic development, water consumption will increase significantly, and the contradiction between water supply and demand will become more acute. It is predicted that in years of moderate drought, the country must achieve a rough balance between water supply and demand. Taking into account strict water-saving measures, the total water demand will be 698.8 billion cubic meters in 2010, 800 billion cubic meters in 2030, and at least 800 billion cubic meters in 2050. 850 billion cubic meters, which requires an increase of 150 billion cubic meters, 250 billion cubic meters and 300 billion cubic meters respectively from the 1995 water supply capacity of 550 billion cubic meters. It can be seen that the water gap is quite large. Only by adhering to the policy of increasing revenue and reducing expenditure and putting expenditure reduction first, further strengthening water conservation work, realizing the optimal allocation and efficient utilization of water resources centered on water conservation, and striving to achieve the basic balance of supply and demand, can we successfully achieve long-term economic development. development goals. Saving water and ensuring the sustainable use of water resources is our common cause and our common responsibility!
