In this 10 ways to save water with pictures post we have briefly explained about 10 ways in which we can save water.
10 Ways in Which We Can Save Water
Because water covers 71% of the earth’s surface, some people wonder why we should conserve it. Ninety-seven percent of all water on the planet is salt water, which is unfit for human consumption. Only 3% of the water on Earth is fresh water, and only 0.5 percent is drinkable.
The remaining 2.5 percent of fresh water is either trapped in ice caps, glaciers, the sky, soil, or underneath the earth’s surface, or it is too contaminated to drink. With rising population rates and only a limited fraction of the world’s water suited for human consumption, it’s only natural that we should protect and maintain this valuable resource.
Water conservation is the practise of utilising water efficiently in order to reduce waste. It takes into account both the quantity and quality of water used. Water is necessary for the survival of all living things. From local consumption to the agricultural business, there is a fundamental necessity for all activities.
10 Ways to Save Water with Pictures
Protection of Water from Pollution
Water pollution has become a global problem now a day’s on-going evaluation of water resource policy is needed to counter this problem. Deaths and diseases are caused worldwide due to water pollution and approximately 14000 people die every day due to water pollution.
Both developed as well as developing countries are facing water pollution problems. Water quality is influenced by many factors like precipitation, climate, soil type, vegetation, geology, flow conditions, ground water and human activities.
The greatest threat to water quality is posed by point sources of industries and municipalities. Activities like mining, Urban development and Agriculture also effect water quality. Non-point source pollution also includes nutrients, sediments and toxic contaminant.
Pollutants may be of different types and having different properties like Stock pollutants which include non-biodegradable plastics, synthetic chemical and heavy metals have no or very little absorptive capacity.
These pollutants accumulate in environment with the passage of time. Their damage increases as their quantity increases. For future generations stock pollutants are burdens. Similarly Fund pollutants have some absorptive property in environment.
They only cause problem when their quantity increases beyond environment absorbance capacity. E.g., Carbon dioxide only causes problem when its amount increases. These pollutants can only be diluted to reduce their toxicity or recycled into non harmful substances.
Rational Use of Groundwater
Groundwater is defined as water that is found beneath the surface of the Earth in conditions of 100 percent saturation. Ninety-eight percent of Earth’s available fresh water is groundwater. It is about 60 times as plentiful as the fresh water found in lakes and streams. Water in the ground travels through pores in soil and rock, and in fractures and weathered areas of bedrock.
India is the world’s largest user of groundwater because of the seasonal nature of the monsoons and the need to draw on a few weeks supply of rainwater over an entire year. What is, therefore, worrying is that India is also the world’s most wasteful user of groundwater.
A recent World Bank report says that of India’s 5,723 groundwater blocks, as many as 1,615, or 29 per cent, are now classified as over-exploited, critical or semi-critical, depending on the extent of depletion of aquifers. If the trend endures unabated, 60 per cent of all groundwater aquifers would be in a critical state in 20 years.
The impacts of population on the quantitative water needs of a locality are related to population density (that is, how the population is distributed geographically), and to the rate of increase or decrease in population growth.
Because population changes affect such variables as the economy, the environment, natural resources, the labor force, energy requirements, infrastructure needs, and food supply, they also affect the availability and quality of the water sources that can be drawn upon for use.
Population is highly correlated with public water supply, about 56 percent of which is allocated for domestic (household) purposes. According to the U.S. Geological Survey, the average per capita public water use in the United States in 1995 was about 179 gallons per capita per day (GPCD) and that for domestic water use was about 101 GPCD. An average per capita figure for all water uses in the United States in 1995 (municipal, industrial, agricultural, etc.) was estimated to be about 1,280 GPCD.
Renovation of Traditional Water Sources
In urban India, the number of water bodies is declining rapidly. For example, in the 1960s Bangalore had 262 lakes. Now, only 10 hold water.
Similarly, in 2001, 137 lakes were listed in Ahmedabad. However, by 2012, 65 were already destroyed and built upon. Hyderabad is another example. In the last 12 years, it has lost 3,245 hectares of its wetlands.
These traditional water conservation methods had been developed in India looking to the nature of rainfall in different regions, but the increasing population necessitated extension of agriculture, leading to deterioration of these traditional sources. Conservation of any traditional water source, instead of being limited to the water reservoir portion, extends to the whole drainage area system where rain water is stored after flowing.
Due to increasing area of agriculture, drainage area of water has been destroyed resulting in reduction of water flow therein. This has caused crisis for the existence of traditional water sources. Water crisis can be prevented by renovating traditional water conservation sources.
Unless complete conservation of rain water is done in any region, the dream of water conservation cannot be fulfilled. Hence, supervision has to be done regarding renovation of dying traditional water conservation places.
Use of Modern Irrigation Methods
Modern Methods of Irrigation utilize cloud-automated and timed sprinkler systems, drip systems and subsurface water lines. Using precise, high resolution ET Everywhere weather data, Smart Irrigation Controllers are able to create specific schedules to maintain landscape health, irrigating only when necessary, based on daily, site-specific runtime adjustments.
A large portion of water can be conserved by adoption of modern methods of irrigation. Irrigation consumes double the quantity of water in comparison to all other uses. Sprinkler and drip irrigation methods save 50 per cent water.
In drop or drip irrigation method, pipes with holes are spread over the surface of land so that the crop directly receives water. There is no loss due to evaporation in this system and almost 95 per cent water is utilized. Thus, maximum water is utilized by this method. Improved modern irrigation methods are thus useful for conservation of water.
Increasing Forest Cover
Waterways and lakes in and near urban areas can be polluted by soil erosion and water runoff that may contain fertilizers and pesticides from landscapes, oil, and sewage.
Trees and vegetation can help reduce water quality problems in communities by decreasing storm water runoff and soil erosion. Trees also absorb some of the nutrients in the soil that would otherwise be washed away.
Communities can have cleaner water by managing existing natural vegetation, planting additional trees, and reducing the use of pesticides and fertilizers.
Change in Crop Pattern
Excess water is not required if crops are grown according to agro-climatic conditions but in the present race of development, changing crop pattern with higher profits has replaced them. These commercial crops require more water than the traditional crops. In north-eastern part of Rajasthan, crops were not grown as per availability of water and intensive cultivation was adopted during the last three decades.
Groundwater was over exploited because of non-availability of surface water and plantation of commercial crops requiring more water. It created serious water crisis. Hence, keeping in mind the experience of Rajasthan, crop rotation should be adopted according to agro-climatic conditions. Agro forestry and horticulture should be given priority in areas having scarcity of water.
One of the primary responsibilities of your county government is managing storm water and protecting homes and businesses from flooding.
A large portion of fresh water in the world becomes devastating due to floods in India, out of a total land area of 32.8 crore hectares, in India, 4 crore hectare land is flood affected, out of which 3.2 crore hectare land can be protected from floods. By construction of embankments and canals a large part of land can be conserved besides minimizing flood losses.
Intensive afforestation can also provide security from floods. If will be helpful in absorption of water in the soil. Drainage areas of Ganges, Yamuna, Mahanadi, Damodar, Kosi and other rivers have been taken up in flood management and security to some limit has been provided to the 1.44 crore hectare land.
Reuse of Urban Waste
Demand for water has increased in cities due to increasing urbanization. There is no provision for waste water treatment in many big towns and cities of various countries of the world. Instead of being reused, it pollutes other water sources.
Such condition is visible in cities of Delhi, Agra and Mathura on the banks of river Yamuna, whereas in many countries, urban water is used after treatment in nearby fields for growing vegetables and fruits. After use of water in urban areas, disposed waste water can be treated and conserved for use in agriculture in the peripheral areas of cities. Such policies should be incorporated while planning urban development.
Uses of Geothermal Water
Geothermally heated waters allow alligators to thrive on a farm in Colorado, where temperatures can drop below freezing.
Geothermal direct use dates back thousands of years, when people began using hot springs for bathing, cooking food, and loosening feathers and skin from game. Today, hot springs are still used as spas. But there are now more sophisticated ways of using this geothermal resource.
Geothermal hot water can be used for many applications that require heat. Its current uses include heating buildings (either individually or whole towns), raising plants in greenhouses, drying crops, heating water at fish farms, and several industrial processes, such as pasteurizing milk. With some applications, researchers are exploring ways to effectively use the geothermal fluid for generating electricity as well. In the United States, most geothermal reservoirs are located in the western states, Alaska, and Hawaii.
