There are various simple ways which we can use on daily basis and save gallons of water daily. Following are save water techniques which we must use to save water at home and other places: We should use shower heads with low-flow (also called as energy-efficient shower heads), low-flush toilets and composting toilets (instead of conventional western toilets as they use large volumes of water) or dual flush toilets (it uses very less water than others). Keep the tap close while doing hand wash, tooth brush, face wash, washing dishes, etc. Collect rain water during rainy season to use in toilet flush, watering plants, sprinkle in garden, etc. Using raw water like sea water or non-purified water in toilet is also good. We should be habitual of reusing or recycling waste water. We should promote rainwater harvesting, using high-efficiency clothes washers, weather- based irrigation controllers, garden hose nozzles, low flow taps in wash basins, swimming pool covers, automatic faucet, etc for water conservation. Water saving techniques should also be given priority in the commercial areas as it is a big area where gallons of water can be saved on daily basis.Water saving techniques in the business areas are like waterless urinals, waterless car washes, infrared or foot-operated taps, pressurized water brooms, cooling tower conductivity controllers, water-saving steam sterilizers (in hospitals and health care units), rain water harvesting, water to water heat exchangers, etc. Result Agriculture field is also a vast area where we can save more water on daily basis if we follow water saving techniques. We can use overhead irrigation for crop irrigation (using center-pivot or lateral-moving sprinklers), minimize evaporation, runoff or subsurface drainage, etc. Use of green manures, recycling of crop residues, mulching, animal manure, etc in the field improves the soil organic matter which again increases the water holding capacity and ability to absorb water (during torrential rains) of the soil. Water saving techniques is also promoted at the social and community level by the municipal water utilities or regional governments through the use of common strategies like public outreach campaigns pay higher price for increasing water use, restrictions on use of clean water for outdoor activities like lawn watering, floor cleaning, car washing, etc. There should be universal metering for water supply to each home just like electricity. This facility is only available some UK households areas and urban Canadian homes. It is estimated by the US Environmental Protection Agency that water metering is an effective technique which alone can reduce water consumption by 20 to 40% on daily basis. The growth of more water-efficient crops adopting less irrigation should be promoted as only crop irrigation takes around 70% of the world’s fresh water. Conclusion I think water saving techniques should be promoted among people living in the societies, communities, villages including business sections as they are the main water users in rough manner. Farmers, children, and women should be taught properly about how to use and save water in efficient manner. They must understand the value of water in their life. Clean water scarcity is 81 not a problem of one country or continent; it is a global issue which needs to be solved globally by increasing awareness about it among people worldwide. жүктеу/скачать 11,88 Mb.
