Essay on Save water in 50 words (Save Water Essay 1)
Water is prerequisite for the existence of all kind of life on earth. Human beings, animals, birds and plants cannot survive without water. First form of life was originated in water. Human body itself is mostly water. We can live without food for 30 days, but without water not even for few days. When water content in the body drops just by 1%, we feel thirsty. If it drops by 10%, there is a danger of death. In case of energy and one source can be replace by other, but water as a resource is mostly irreplaceable. Water is the most critical limiting factor for many aspects of life such as food security, health care, biodiversity conservation, environmental stability and economic growth.

We need water for drinking, cooking, washing, cleaning, toilet use and gardening. We also need water for agricultural wheat, rice, vegetables, fruits, sugarcane, coffee, tea and etc. Various non-food items like cotton also use water. Power plants need water for generating electricity and for cooling purpose. Various types of industries use water as a solvent, coolant or for cleaning and washing purposes. Other kinds of life also need water to drink and to clean themselves. Natural system like wetlands, lakes and delta also need water.As per an estimate a human being needs 50 litres water per day, though 100-200 litres is often recommend. Adding the needs of agriculture, industry and energy sectors, the recommend minimum annual per capita requirement is about 1700 m3.
About 75% of the earth is cover by water, still we have no water for drinking in most parts of the world. The reason behind that is 97% of the world’s water is in the ocean, which is too salty, and cannot be used for drink and other purposes. Of the remaining 3 % , two-third is locked up in glaciers. That leaves a mere 1% or 14 million km. Most of our water supply comes from rainwater. Annual fresh water supply in the form of rains is 40,000 km and this amounts to about 5700 m2 per person per year (for a population of 7 billion). This appears to be plentiful, as minimum annual requirement per person is only 1700 m. Thus, there should be no water scarcity, but the actual picture is totally different.

Rivers have great mythic signiﬁcance for us. However we have not treat our water resources with the care they deserve. The need for water for agriculture, industry and personal consumption is understood by all, especially when big cities and rural areas reel under water shortages in the summer. The pollution of our rivers and water bodies is also reﬂect in the health problems that occur in many parts of the country. Urgent attention is need to overcome these problems in the coming years. Recycling of water and water conservation will be a critical component of our daily lives in the coming millennium.
We would like to share with the readers another aspect of water: water as a transport medium. Waterways are one of the most energy eﬃcient forms of transport. Road transport services and railways occupy a prominent place in our transport system accounting for 53.3 per cent and 31.7 per cent respectively of the total GDP of the entire transport sector in 1992–93. On the other hand, water transport has a share of only 6.5 per cent. The GDP in the road transport sector has been growing at an annual rate of 8.8 per cent between 1980–81 and 1992–93 as compared to the growth rate of just 3 per cent in water transport.
There are several factors which explain the diminishing importance of waterways. The main disadvantage of waterways is that they can transport goods only on ﬁxed and limited routes unlike the road and railway systems which have the capacity to provide services between a large number of points to suit the requirements of the users. Secondly, there has been a rapid expansion of the railway and road networks during the ast four decades, while waterways have remained almost neglecte. Public sector investment in inland waterways transport (IWT) has been very small in comparison to the investment on other modes of transport.
It was only in the Seventh Plan that some attention was paid to the development of waterways and water transport. The use of IWT is conﬁned only to certain areas like the Mandovi river in Goa, Ganga in the eastern regions, the canals and backwaters of Kerala, Karnataka, Maharashtra and Andhra Pradesh.

In our daily life waters play main role. India is the land of rivers. The Aryans settled here seeing the availability of water for various purposes like cultivating and domestic purposes. At that time the population was very low, so the water in the rivers was more than enough. But today, there is a tremendous rise in the population of India. People in the rural parts of India have to cover long distances with their utensils to fetch drinking water. There is an acute shortage of water on an average in India. At the same time in the rainy season there are floods in many parts India. These floods also cause a lot of destruction of public properly and loss of lives. Besides the huge amount of water in the rivers is also wasted. To counter these recurring floods in the rainy season & the droughts in the summer proper water management is necessary.
The water, which through the rivers flows down to the seas is wasted. To utilize this water, dams need to be built on all the rivers across India A dam once built can be used for various purpose. It can store huge amount of water, which can be supplied through canals to drought prone regions. Farmers can use this facility to increase their yield, as they can take crops the whole year round. Electricity can also be generated on these dams, which is an additional benefit.
Reservoir should be built in every free places so that water can store in huge amount. This water can be use in many by needy people around the reservoir area. For keep it hygienic, proper precaution must be taken by people as well as municipal co operation so that it won’t be harmful. Like reservoir, well type container can also be built in congested places so that rain water can store.

Smart waterways should have suﬃcient navigable depth and width so that larger vessels with higher draft may be able to navigate them. The condition of the waterways should permit navigation throughout the year. They should have smooth bends and minimum siltation, with suﬃcient vertical clearance so that the vessel’s movement is not hindered. Vessels should be able to navigate at least eighteen hours per day on the waterways. Eﬃcient loading and unloading facilities should be available at several points. The waterways should be adequately lighted and equipped with modern navigational and communication aids. If we have smart waterways, movement of cargo, be it food materials or cement, even from Punjab to neighbouring Bangladesh, can be done very effectively.
Among other things, the technology imperatives for waterways are:
Designing terminals to take care of both bulk handling and general handling and storage; introduction of mobile grab cranes and conveyor belt loaders; introduction of lighterage system for transferring cargo as well as containers; construction of ﬂoating jetties to provide ﬂexibility in movement and designing appropriate jetties with necessary equipment depending on the nature, weight and volume of the cargo. Thus modern electronic technologies can impart new vigour to an ancient transport system and also save considerable energy in the process.
Wastage of water is another issue. At those places where water is abundant or is supplied regularly, wastage of water is considerably large. Public taps are kept open, which lead to the wastage of precious water. People don’t realize the importance of water when it is abundant.
The distribution of rainwater is not uniform over space and time. Some areas of the world get too much water while others get too little. Further, most of the rainfall occurs over a short period in the year leading to floods in monsoon and drought in summer. Global warming also have changed the rainfall patterns. Much of the rainfall occurs in remote places that are inaccessible. The run-off aided by deforestation, reaches the ocean quickly before it can be used.
Causes of Fresh Water Scarcity and What are its uses?
One of the most prominent reason of water scarcity is rapidly growing population, as a result of which, the demand is going up sharply, while the available amount has been going down. The rapidly increasing industrialization is increasing the pollution of rivers, lakes, and groundwater, thus affecting the supply adversely. Pollution has made many water resources unfit for use. The rates of groundwater extraction for irrigation and other purposes are high that ancient aquifers are getting depleted. As a result water tables are falling,causing major rivers of the world to be drained dry before they reach the sea.
How to Save Water and What is water conservation essay?
As water is one of the most valuable source on earth, we need to conserve it, otherwise there will no pure water even for drinking in coming years. Some measures which can be adopt for water conservation are
(i) Decreasing Run-off Losses – Most of the water falling on earth is lost in the form of run-off. To reduce run-off losses, water should be allow to infiltrate into the soil.
Some methods to increase infiltration are
(a) Contour Cultivation-Contour cultivation on small furrows and ridges across the slopes can trap rainwater and allow more time for infiltration. Terracing construct on deep soils have large water storage capacity. Large On gentle slopes, run-off can be spread area for better infiltration.
(b) Terrace Forming – In this method, a series of benches ate
(c) Water Spreading – Water can be spread of by channeling or lagoon level. In channeling, water flow is controlled by a series of diversions with vertical intervals. In lagoon levelling, small depressions are construct, which can catch the run-off water. dug in the area for temporary storage of water.
(d) Improved Water Storage System- – Water storage structures like farm pond, dug outs, etc. built by individual farmers can also reduce run-off Chemical wetting agents.
(e) Chemical Treatment (surfactants) when added to the normal irrigated soils can increase the water intake rates. Chemical conditioners like gypsum (CaSO2H,O) when applied to sodic soils improve their permeability and reduce run-off.
(f) Using Crop and Animal Residuces- Surface residues like tillage, mulch, etc. and animal residues can help in reducing run off by allowing more time for water to infiltrate into the soil.
(ii) Reducing Evaporation Losses- This method is specially relevant in humid regions. In this method, horizontal barriers of asphalt are placed below the soil surface. This increase the water availability and crop yield by 30-40%.This method is more effective on sandy soils. An artificial co-polymer of starch and acrylonitrile can absorb water upto 1400 times of its weight
(iii) Reducing Irrigation Losses-Irrigation losses can be reduced by
(a) Irrigation in early morning or late evening, when sun is not there.
(b) Using lined or covered canals to reduce seepage.
(c) Using modern irrigation methods like sprinkling irrigation and drip irrigation.
(d) Growing hybrid crop varieties, requiring less water and can tolerate saline water.
(iv) Storing Water in Soil-Soil in humid region, when wett to full capacity can store water in the soil root zone. Leaving such soil fallow for one season water can be made available for the crop grown in next season.
(v) Preventing Water Wastage – Water wastage can be reduced in households, commercial buildings and public places by
(a) Closing taps when not in use.
(b) Repairing any leakage, if there.
(c) Using small capacity flush in toilets.
(vi) Re-using Water- Used water from households and industries, after treatment can be used for washing cars, gardening and irrigation.
(vii) Increasing Public Awareness -Educating people about the importance of water can help reduce water wastage and conservation.

Need to Save Water
Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock, water for irrigation, etc. In many places the water collect is just redirect to a deep pit with percolation. The harvested water can be used for drinking water as well, if the storage is a tank that can be accessed and cleaned when needed. Ground water resource gets naturally recharge through percolation. But due to indiscriminate development and rapid urbanization and exposed surface for soil has been reduced drastically with resultant reduction in percolation of rainwater, thereby depleting ground water resource. Rainwater harvesting is the process of augment the natural filtration of rainwater into the underground formation by rainwater to cater demands of water, for drinking, domestic purpose and irrigation is term as rainwater harvest”.
Rainwater harvesting is essential because some artificial methods. “Conscious collection and storage of Surface water is inadequate to meet our demand and we have ground water.
(ii) soil has decrease drastically and recharging of ground water has diminish.
(iii) To arrest ground water decline and augment ground water table.
(iv) To beneficiate water quality in aquifers.
(v) To conserve surface water runoff during monsoon.
(vi) To reduce soil erosion.
(vii) To inculcate a culture of water conservation.
Advantages – Advantage of rainwater harvesting are as follows
(1) Makes use of a natural resource and reduces flooding, storm water runoff, erosion, and contamination of water with pesticide, sediments, metals, and fertilizers.
(ii) Reduces the need of importing water.
(iii) Excellent source of water for landscape irrigation, with no chemicals such as fluoride and chlorine, and no dissolved salts and minerals from the soil.
(IV) Home systems which are relatively simple to install and operate can reduce the water bill.
(v) Promotes both water and energy conservation.
(vi) No filtration system required for landscape irrigation.
Disadvantage -Following are the disadvantages of rainwater harvesting
(i) Rainwater storage and delivery systems are costly to install.
(II) The payback period varies depending on the size of storage Limited and uncertain local rainfall.and complexity of the system.
(III) Can take considerable amount of time to “pay for itself”.
(Iv) Requires some technical skills to install and provide regular maintenance.
(vi) If not installed correctly and may attract mosquitoes.
(vii) Certain roof types may seep chemicals, pesticides, and other pollutants into the water that can harm the plants.
(viii) Rainwater collected during the first rain season is generally not needed by plants until the dry season. Once catchment is full, advantage of future rains cannot be obtained.
The spatial limitation of waterways cannot, however, be considered a major constraint in the development of water transport as 61 per cent of the extent of navigable waterways remains un utilize . Attention, therefore, needs to be focus on how best the current navigable water system of 14544 km can be utilized to develop an eﬃcient transport system. It is imperative to identify and remove the physical and infrastructural constraints.
Some of the major constraints are given below:
1)Navigational hazards due to bank erosion, siltation and deterioration of channels
2)Shallow water and narrow width of rivers
3)Lack of adequate navigational aids https://webguideanyplace.com/biography-of-a-clock/
4)Inadequacy of horizontal and vertical clearance, inadequacy of hydraulic structure (locks), and old vessels; and Loss in the cost of advantage of IWT when the place of origin and destination is not located on the river bank.
An analysis of the current status of the two major waterways in the country, viz. the Ganga-Bhagirathi-Hooghly (GBH) river system and the Brahmaputra river reveals that presently mostly bulky and non-perishable commodities are being tra on these two river systems. There is, however, a g ime of traﬃc on them. But this potential for increasing the volume of traﬃc on them. But this he exploited only through development of an integrated and IWT. This would also require the network of rail, road and IWT. This would a of eﬃcient mechanical cargo-handling facilities at various points of the multimodal transport network. Althouch some waterways in the country have been classiﬁed as national waterways, there is a need to modernize these by making appropriate use of available technology, such as position location and communication systems, so that they become ‘smart waterways’.

“Water is the driver of life”, said, Leonardo da Vinci. The water, in global terms is a rare liquid, Ninety seven per cent of all the water on earth is salty. Although it carries many rock particles in suspension, it is chemically very pure. Water without considerable quantities of salt in it is a rare commodity but essential for all living organisms, Another 2 per cent is ice locked up in the polar regions and of the remaining 1 per cent, a good deal is trapped in underground reservoirs. What remains is man’s main source of water supply for all his needs—the surface water of lakes, streams and rivers, which are getting heavily polluted. For every 1000 gallons of water on earth, only three gallons are drinkable.
The global supply of water is ﬁxed and ﬁnite. There is essentially no more water today than there was when civilization began. The water that lashes the earth today as rains is the same water that evaporated yesterday from the seas.
If man is to increase the supply of potable and usable water, he has to harness icebergs of Antarctica, or underground resources or to purify the polluted surface water. Indian sub-continent with 6000 km, coastal water, extending into the sea upto 2000 nautical miles, numerous long and small rivers and a good number of man made lakes are the precious water resources needed to meet the rapidly increasing demands of unimaginable growing population. The principal rivers of India and their main tributaries, canals and irrigation systems stretch 140,000 kms. Reservoirs and lakes cover 2.9 million hectares.
The U.N. water conference at Mar del Plate in Argentina held in March, 1977 was perhaps the ﬁrst multi-disciplinary effort to develop an international consensus on water management.And The conference designated 1981–90 as the international water supply and sanitation decade and made 22 recommendations urging the need for management of water resources. World should cherish water as a resource too dear to waste. Clean water can bring profound release of creative energy to every person.
Today world per capita use of water is 710 cubic meter per year. Total human use of water is 2,600 cubic kilometer per year. And It was estimated that by the year 2000 world use of water would more than double to 6,000 cubic kilometer per year a signiﬁcant fraction of the naturally available fresh water.
The average total runoff from the earth’s rivers is approximately 48,000 cubic kilometers and but its distribution is not uniform. And Some occurs in relatively uninhabited regions such as Antarctica which produces 2,300 cubic kilometers or about 5 per cent of the earth’s total runoff. South America, which includes the relatively uninhabit, Amazon basin, provides 16,000 cubic kilometers or about the third of the world’s total runoff, and in North America total runoff is about 8,100 cubic kilometers per year. https://webguideanyplace.com/biography-of-a-clock/
Water is a heterogeneous resource that can be found in either a liquid ,solid and gaseous form at a number of locations at or near the earth’s surface. Depending upon the speciﬁc location of water, the resilience time may vary from a few days to many thousand years. Furthermore, more than 99 per cent of the earth’s water is unavailable or unsuitable for beneﬁcial human use because of salinity (sea-water) or location (ice caps and glaciers). And thus the amount of water for which all people on the earth compete is much less than 1 per cent of the total.
