49 Ways of Saving Water

49 Ways of Saving Water




  1. Never put water down the drain when there may be another use for it such as watering a plant or garden, or cleaning.
  2. Verify that your home is leak-free, because many homes have hidden water leaks. Read your water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, there is a leak.
  3. Repair dripping taps by replacing washers. If your tap is dripping at the rate of one drop per second, you can expect to waste 2,700 gallons per year which will add to the cost of water and sewer utilities, or strain your septic system.
  4. Check for toilet tank leaks by adding food colouring to the tank. If the toilet is leaking, colour will appear within 30 minutes. Check the toilet for worn out, corroded or bent parts. Most replacement parts are inexpensive, readily available and easily installed. (Flush as soon as test is done, since food colouring may stain tank.)
  5. Avoid flushing the toilet unnecessarily. Dispose of tissues, insects and other such waste in the rubbish bin rather than the toilet.
  6. Take shorter showers. Replace you showerhead with an ultra-low-flow version. Some units are available that allow you to cut off the flow without adjusting the water temperature knobs.
  7. Use the minimum amount of water needed for a bath by closing the drain first and filling the bath only 1/3 full. Stopper bath before turning water. The initial burst of cold water can be warmed by adding hot water later.
  8. Don't let water run while shaving or washing your face. Brush your teeth first while waiting for water to get hot, then wash or shave after filling the basin.
  9. Retrofit all wasteful household taps by installing aerators with flow restrictors.
  10. Operate automatic dishwashers and clothes washers only when they are fully loaded or properly set the water level for the size of load you are using.
  11. When washing dishes by hand, fill one sink or basin with soapy water. Quickly rinse under a slow-moving stream from the tap.
  12. Store drinking water in the refrigerator rather than letting the tap run every time you want a cool glass of water.
  13. Do not use running water to thaw meat or other frozen foods. Defrost food overnight in the refrigerator or by using the defrost setting on your microwave.
  14. Kitchen sink disposals require lots of water to operate properly. Start a compost pile as an alternate method of disposing food waste instead of using a garbage disposal. Garbage disposals also can add 50% to the volume of solids in a septic tank that can lead to malfunctions and maintenance problems.
  15. Consider installing an instant water heater on your kitchen sink so you don't have to let the water run while it heats up. This will reduce heating costs for your household.
  16. Insulate your water pipes. You'll get hot water faster plus avoid wasting water while it heats up.
  17. Never install a water-to-air heat pump or air-conditioning system. Air-to-air models are just as efficient and do not waste water.
  18. Install water softening systems only when necessary. Save water and salt by running the minimum amount of regenerations necessary to maintain water softness. Turn softeners off while on vacation.
  19. Check your pump. If you have a well at your home, listen to see if the pump kicks on and off while the water is not in use. If it does, you have a leak.
  20. When adjusting water temperatures, instead of turning water flow up, try turning it down. If the water is too hot or cold, turn the offender down rather than increasing water flow to balance the temperatures.
  21. If the toilet flush handle frequently sticks in the flush position, letting water run constantly, replace or adjust it

Saving Water Outdoors

  1. Don't over-water your lawn. As a general rule, lawns only need watering every 5 to 7 days in the summer and every 10 to 14 days in the winter. A hearty rain eliminates the need for watering for as long as two weeks.
  2. Water lawns during the early morning hours when temperatures and wind speed are the lowest. This reduces losses from evaporation.
  3. Don't water your street, driveway or sidewalk. Position your sprinklers so that your water lands on the lawn and shrubs ... not the paved areas.
  4. Install sprinklers that are the most water-efficient for each use. Micro and drip irrigation and soaker hoses are examples of water-efficient methods of irrigation.
  5. Regularly check sprinkler systems and timing devices to be sure they are operating properly. It is now the law that "anyone who purchases and installs an automatic lawn sprinkler system MUST install a rain sensor device or switch which will override the irrigation cycle of the sprinkler system when adequate rainfall has occurred." To retrofit your existing system, contact an irrigation professional for more information.
  6. Raise the lawn mower blade to at least three inches. A lawn cut higher encourages grass roots to grow deeper, shades the root system and holds soil moisture better than a closely-clipped lawn.
  7. Avoid over-fertilising your lawn. The application of fertilisers increases the need for water. Apply fertilisers that contain slow-release, water-insoluble forms of nitrogen.
  8. Mulch to retain moisture in the soil. Mulching also helps to control weeds that compete with pants for water.
  9. Plant native and/or drought-tolerant grasses, ground covers, shrubs and trees. Once established, they do not need to be watered as frequently and they usually will survive a dry period without any watering. Group plans together based on similar water needs.
  10. Do not hose down your driveway or sidewalk. Use a broom to clean leaves and other debris from these areas. Using a hose to clean a driveway can waste hundreds of gallons of water.
  11. Outfit your hose with a shut-off nozzle that can be adjusted down to fine spray so that water flows only as needed. When finished, "Turn it Off" at the tap instead of at the nozzle to avoid leaks.
  12. Use hose washers between spigots and water hoses to eliminate leaks.
  13. Do not leave sprinklers or hoses unattended. Your garden hoses can pour out 600 gallons or more in only a few hours, so don't leave the sprinkler running all day. Use a kitchen timer to remind yourself to turn it off.
  14. Check all hoses, connectors and spigots regularly.
  15. Consider using a commercial car wash that recycles water. If you wash your own car, park on the grass to do so.
  16. Avoid the installation of ornamental water features (such as fountains) unless the water is recycled. Locate where there are mineral losses due to evaporation and wind drift.
  17. If you have a swimming pool, consider a new water-saving pool filter. A single backflushing with a traditional filter uses from 180 to 250 gallons or more of water. General Water Saving Tips
  18. Create an awareness of the need for water conservation among your children. Avoid the purchase of recreational water toys that require a constant stream of water.
  19. Be aware of and follow all water conservation and water shortage rules and restrictions that may be in effect in your area.
  20. Encourage your employer to promote water conservation at the workplace. Suggest that water conservation be put in the employee orientation manual and training program.
  21. Patronise businesses that practice and promote water conservation.
  22. Report all significant water losses (broken pipes, open hydrants, errant sprinklers, abandoned free-flowing wells, etc.) to the property owner, local authorities or your Water Management District.
  23. Encourage your school system and local government to help develop and promote a water conservation ethic among children and adults.
  24. Support projects that will lead to an increased use of reclaimed waste water for irrigation and other uses.
  25. Support efforts and programs to create a concern for water conservation among tourists and visitors to our state. Make sure your visitors understand the need for, and benefits of, water conservation.
  26. Encourage your friends and neighbours to be part of a water conscious community. Promote water conservation in community newsletters, on bulletin boards and by example.
  27. Conserve water because it is the right thing to do. Don't waste water just because someone else is footing the bill such as when you are staying at a hotel.
  28. Try to do one thing each day that will result in a savings of water. Don't worry if the savings is minimal. Every drop counts. And every person can make a difference. So tell your friends, neighbours and co-workers to "Turn it Off" and "Keep it Off".

Save water in our life

 

First, water conservation tips: 1, toys for children intimate partner. But some toys (such as water spray guns) need to consume water, not worthy of recommendation, particularly in the areas of water scarcity, but also should not be used. There are some naughty young people, leading in the water below a big fight with each other water, water scattered, very happy, insidious, clean the wet ground, in the past, the pedestrian was scared, a large number of Water is also wasted. More bad! 2, washing utensils in the home water-saving washing utensils, the best dishes on the first paper to remove the oil, and then hot water again, and finally with more warm water or cold running water. Second, take a bath of water-saving: With shower nozzle: (1) Institute of regulating temperature. (2) not to head to open water from start to finish, and should not open. (3) as far as possible before you get wet from head to toe, on the whole body soapTu, the last running water. Do not separate shampoo, washing upper body, lower body and foot washing. (4) to concentrate on taking a bath, seize the time, do not refrain from being washed or side chat edge. Let alone in the bathroom and a good friend of a big fight. To remember: Time is the water! (5) not to use the opportunity to take a bath "in passing" the clothes, shoes. Bathing in the bathtub, we should pay attention: Do not over water, pots 1/3-1/4 sufficient. Third, water-saving toilets: (1) If you think that the toilet tank is too large, can be a piece of bricktank filled with water or a large drink bottles, in order to reduce the volume of flushing water every time. It should be noted, bricks or drink bottles of water tanks on the prejudice component of the local campaign. (2) water tank leakage is always the most influent rubber sealing lax than irrigation, water filled with later flow away from the overflow hole; outlet sealing rubber lax devascularization not take water into the pipes do not stopped to water. (3) domestic wastewater collection flush toilets, you can use a strip of water, saving water. (4) garbage regardless of size, thickness, should be clear from the garbage channel, rather than water from the toilet to Chong.

Why should we save water?

water is very important
  It is all to know that water is very important for human in the life.There is a saying that human is made of water.so we can not lose it.In other words,we would die without it.For example,fish would lose its life if it leaves water.
  so we should keep water from being poluted.In a word,water is the source of the life.We cannot lose it.


How to save water?

As we know ,water is very important to all of us so we shoul try our best to save it.
I think saving water is not only good for ourselves but for our society and at last for our next generation.
In face we can do many things in our daily life to save water.Firstly,make sure we can turn off the tap in time.Secondly make sure we can reuse the water after we finish washing. Lastly ,we can also use the rain water to do the washing.



How to protect water?
First we must protect the factory form pouring waste water into the river

  Second we should stop people from throwing litter into the river.many kinds of litter may pollute the envirenment.

  Finally we can tell the visitors how important the water is.

The global water situation (http://www.savewater.com.au/research-and-resources/why-save-water/global-situation)

The global water situation

Fresh water is essential to our existence - it allows us to produce food, manufacture goods and sustain our health. It is also an essential part of the natural environment which supports all human, plant and animal life.

Global water consumption has risen almost tenfold since 1900, and many parts of the world, including many parts of Australia, are now reaching the limits of their supply. World population is expected to increase by 45% in the next thirty years, whilst freshwater runoff is expected to increase by 10%. UNESCO has predicted that by 2020 water shortage will be a serious worldwide problem.

One third of the world's population is already facing problems due to both water shortage and poor drinking water quality. Effects include massive outbreaks of disease, malnourishment and crop failure. In addition, excessive use of water has seen the degradation of the environment costing the world billions of dollars.

Some sobering examples of water consumption around the world include:

  • So much water is drawn from the Colorado River (which formed the Grand Canyon) that often it doesn’t flow to the sea.
  • The Aral Sea, the fourth largest inland sea, will cease to exist within the next decade, as its waters are rapidly being used up for farming.
  • Our own cultural icon, the Snowy River, was reduced to about 1% of its original flow before action was taken to restore environmental flows.


The Australian situation

Australia is the driest populated continent on earth, (Antarctica is drier, but does not support the population of Australia), but we are the greatest consumers of water per person.

The average annual rainfall in Australia is 469 mm/yr, well below the global average of 746mm/yr. 70% of our continent is classified as desert or semi-desert, with little or no precipitation.

On average, each Australian consumes around 100,000 litres of fresh water per year. When you factor in the water used to produce the food we eat and the products that we use in everyday life, we are each responsible for using about 1 million litres of water per year, or a total of about 24,000 GigaLitres.

That's enough to fill Sydney Harbour 48 times over! About 70% is attributed to agricultural irrigation, 9% to other rural uses, 9% to industrial uses and 12% to domestic use.
