Essay on Rain Water Harvesting for Students and Children

500 words essay on rain water harvesting.

Rainwater Harvesting is one of the most commonly used methods to save water. It refers to storing of rainwater for various uses. The notion behind rainwater harvesting is to not waste the rainwater and prevent it from running off. In other words, it is done to collect rainwater using simple mechanisms. This method is very useful considering the water scarcity that is happening in India. Moreover, rainwater harvesting is so easy that almost anyone can do it. We must encourage this practice to help people get access to clean water easily without any cost.

Importance of Rainwater Harvesting

As we know by now, rainwater harvesting is very easy and economical. Following the water scarcity in so many parts of the world, rainwater harvesting has become the need of the hour. It must be practiced by people of all regions. This will also give them a sense of comfort in knowing that they won’t have to face water scarcity.

Furthermore, rainwater harvesting holds more importance than you actually think it does. As we know that surface water is not enough to meet the demands of the people, we can get additional help from rainwater. Also, most people now depend on groundwater for their uses. Many houses and even flats have submersible pumps in their place. The groundwater is decreasing day by day because of excessive usage, deforestation, urbanization and more.

Thus, when we practice rainwater harvesting, it can maintain the level of the groundwater. That way, we all can make use of groundwater as it will keep on replenishing through rainwater harvesting. Moreover, rainwater harvesting prevents water from logging on roads. It also reduces the chances of soil erosion. Most importantly, rainwater harvesting improves the quality of water which we consume, as it is the purest form of water.

Rainwater Harvesting Methods

Rainwater harvesting is a very simple method that can be practiced by anyone. There are primarily two types of rainwater harvesting methods. The first one is surface runoff harvesting. In this method, the water that runs off the surface is focused on. We see how the surface runoff causes a lot of loss of water. However, if we make proper arrangements, we can even save that water to use for various purposes.

In this method, we can collect the surface runoff water by making a path that directs to a storage space like a tank or pond. This can help store water in a large amount which can be used later for a lot of work. Everyone can design an efficient system which will collect large amounts of water from roads, gardens, parks and more. It will definitely be enough to sustain a community and even a city is designed on a larger level.

However, the runoff water will have a lot of impurities. Therefore, it is important to first filter the water properly so it can be reused for all purposes, whether it is drinking or cooking.

Next up, we have rooftop rainwater harvesting. Here, the roof of a house or building works as a rainwater collection unit. It includes equipping the roof with pipes that direct to a pit or tank. These pipes will divert the water falling on the roof in the tank to save water from falling off. This is a very economical and efficient way to harvest rainwater.

Rainwater Harvesting Essay for Students in English [500 Words]

January 6, 2021 by Sandeep

Essay on Rainwater Harvesting: To beat water scarcity and sustain lives across continents, rainwater harvesting is a practice followed by nations worldwide. It is one of the most innovative solutions to save water. It helps to balance water cycle, avoid rainwater flooding in low lying regions, and better utilise rainwater for purposes like gardening, washing and cleaning purposes.

Essay on Rainwater Harvesting 500 Words in English

Below we have provided Rainwater Harvesting Essay in English, suitable for class 6, 7, 8, 9 & 10.

Rainwater Harvesting is a form of harvest in which rainfall is gathered and deposited for potential use instead of being allowed from getting washed out. Rainwater can be collected from rivers or dome to a bottomless pit (well, pipe, or borer), aquifer, percolated pond or collected from dew or fog with filets or other devices. The uses include greenhouse water, cattle irrigation, household use, indoor heating for houses, etc. The extracted water can also be used as drinking water, for long-term storage and other uses, including irrigation of groundwater.

India has received significant water supplies from nature. We have seasonal rivers like the Ganga, Brahmaputra, Yamuna, Beas and others with their affluent and distributors, in the north and eastern India. In central and peninsular India, we have spring and rain-fed rivers like the Godavari, Krishna, Narmada, Tapti and Kaveri. Notwithstanding these immense available water supplies, we face a countrywide water crisis. The growing population, growing industrialization and developing agriculture have raised the need for water over the years.

Rainwater Harvesting in India

In India, it is more than 4000 years since the rainwater was harvested. It is a simple method to capture and store rainwater. Since ancient times, rainwater irrigation systems have been used as a source of potable water, irrigated water as well as agricultural water. The systems are simple to create from cheap, locally-produced materials and have proven popular in most areas. The most significant benefit of rainwater is that water quality is usually good, and no preparation before consuming is needed.

There are several methods to harness rainwater, ranging from relatively necessary to highly complex industrial systems. Usually, on the roof or the ground, rainwater is collected. The rate at which rainwater can be obtained from any system depends entirely on the strength of the precipitation and the area and general performance of the systems in operation.

Methods of Rainwater Harvesting

Some of the most common ways to harness and treat urban rainwater are:

• Surface Runoff Harvesting: The most effective approach in urban areas is Surface Runoff harvesting. Soil water sources are redirected here and deposited on the soil or underground to be used for future uses in specially built reservoirs. This ensures the constant water supply for general domestic applications as well as clean, drinking water.
• Rooftop Rainwater Harvesting: Rooftop rainwater harvesting is the most common alternative for urban harvesting. The system is accessible in a single home setting, hospitals, colleges and other academic buildings with more roof space. The rooftop rainwater storage idea is fundamental and easy to do. A container has to be installed or put under the surface of the roof, which collects and converts the rainwater from timber, bamboo or PVC pipes. While this is the basic principle, it is much more complex to harness industry-grade rooftop rainwater in large complexes.
• Recharge Pits: The creation of refill pits to carry rainwater is also a growing rainwater harvesting method. Recharge boxes can be of any size and shape, depending on the strength of plumage in a given area. These recharge pits must be filled with gross sand, boulders and gravel which act as natural filters that protect the soil and the soil is usually carried by the first rainwater flood.

Rain Water Harvesting Essay

One of the most effective practices and approaches used to encourage water conservation is the use of rainwater collection systems. Today, the lack of high-quality water is a significant source of worry. Rainwater can be used for different animal needs as well as agriculture, cleaning, washing, bathing, and cooking because it is pure. Here are some sample essays on rain water harvesting.

100 Words Essay on Rain Water Harvesting

200 words essay on rain water harvesting, 500 words essay on rain water harvesting, importance of rainwater harvesting, methods of rainwater harvesting.

To collect and store rainwater for use in the future, a technique known as "rainwater harvesting" is used. Rainwater can be collected in either natural or artificial tanks. Surface water can also be gathered by allowing it to sink into underground aquifers if it hasn't already been lost by surface overflow.

Rainwater can also be collected by harvesting it from rooftops. For those who live in regions with little rainfall, it is quite essential. They can continue harvesting seasonal crops using the rainwater they have collected, even in the lack of a regular water source. Rainwater is gathered into artificial ponds or tanks every time it rains.

A fundamental process called rainwater harvesting involves rainfall seeping into the ground's water table through open land. Rainwater collection is relatively easy to do at home and has a significant positive impact on the environment and our ecosystem. Our cities and villages will have to rely on the earth's finite supply of fresh water if rainwater harvesting is not done correctly. We must keep in mind that freshwater makes up only 3% of the total amount of water on Earth. We will run out of water before our future generations can survive if we do not adopt innovative water-saving techniques.

Additionally, rainwater collection is more important than we might assume. We can use rainfall as an extra resource because we are aware that surface water is insufficient to supply all the needs of the population. Additionally, groundwater is currently the primary source of water for most people.

The entire population of the country cannot adopt rainwater collection quickly. Governments and members of civil society must work together to advance the process, which is gradual. There should be awareness-raising and educational efforts in rural areas of the nation as well as educational institutions to raise the necessary understanding about the advantages of rainwater harvesting because it is one of the sustainable sources of water collection that we can rely on.

The most popular way to conserve water is through rainwater harvesting. It corresponds to the act of collecting rainwater for later use. Using rainwater for agricultural purposes and preventing it from evaporating are the two goals of rainwater gathering. This means that different techniques are used to collect rainwater. Considering India's current water shortage, this strategy is beneficial. In addition, it is quite simple to practice rainwater harvesting which allows people to do it without investing too much into it. We must support this approach to enable people to get clean water freely.

The rainwater collection is simple and inexpensive. Rainwater collection has become essential due to the water shortage that has affected many areas of the world. Individuals from all regions must practice it. Submersible pumps are used in a lot of homes, including apartments. Due to excessive use, deforestation, urbanisation, and other factors, the groundwater is getting lower and lower every day. As a result, when we collect rainwater, the groundwater level may be maintained. In this manner, everyone can utilise groundwater because rainwater collection would keep its levels up. In addition, collecting rainwater stops water from collecting on highways. Soil erosion is also less likely to happen as a result. Since rainwater is the cleanest form of water, it is crucial that rainwater harvesting be practiced by people ardently.

Everyone can make use of the easy-going technique of rainwater gathering. Rainwater-gathering plans mostly fall into two categories. Surface runoff harvesting comes first on the list. This approach concentrates on surface-running water. We observe a significant loss of water due to surface runoff. If we take suitable precautions, we may even be able to preserve the water for later use.

By creating a channel that leads to a storage area like a pond or tank, we can use this technique to collect surface runoff water. Large amounts of water can be stored in this way and used later. Everybody can create a system that effectively contains enormous amounts of water from parks, gardens, and roadways. If consider on a bigger scale, it will be sufficient to support a city and even a community.

But the water from runoff will be heavily contaminated. It is crucial to adequately filter the water first so that it may be used for drinking and cooking as well as other functions. Here, a structure or home's roof is a device for collecting rainwater. A pit or tank may be reached by installing pipes on the roof. The water that would otherwise fall off the roof will be saved by these pipes, which will redirect it into the tank. This method of gathering rainwater is incredibly cost-effective and helpful.

Real-Life Inspiration | One of the Indian states, Tamil Nadu, became the first to make rainwater collection mandatory. On May 30, 2014, the Tamil Nadu state government announced plans to build over 50,000 rainwater harvesting systems throughout Chennai. In Tamil Nadu, rainwater tanks have been installed in about 4,000 temples. These tanks are used for numerous temple activities and to refill the groundwater. Thus, rainwater harvesting is needed when water resources are limited and polluted due to the large population.

Rain Water Harvesting Essay 1 (100 words)

Rain water harvesting is a technique used for collecting and storing rainwater by using various means in different resources for the future use purpose (like cultivation, etc). Rain water can be collected into the natural reservoirs or artificial tanks. Another method of collection is infiltration of surface water into the subsurface aquifers before getting lost by surface overflow.

Rooftop harvesting is also a method to collect rainwater. It is of big importance to the people living in the less rainfall areas. They can continue seasonal crop harvesting using collected rain water even in the lack of regular water supply. Whenever it rains, rain water gets collected into the man made ponds or tanks.

Rain Water Harvesting Essay 2 (150 words)

Rain water harvesting is the collection of rainwater into the man made resources or any natural resource like pond, lake, etc at the same place where it falls from rooftops or ground. Two main techniques of rainwater harvesting are storage for future use and recharge into the ground. It can be used for crop harvesting, gardening, toilets, etc. Following are the benefits of rainwater harvesting at individual or city-wide level:

• It helps in reducing the water supply bills especially to the institutions.
• Rainwater recharged to the ground positively affects groundwater quality by diluting fluorides, nitrates and its salinity.
• It contains almost neutral pH and zero hardness which makes it more able to be used in homes, industries, institutions and other commercial establishments.
• It may reduce the stress of public water supply sources.
• Recharge of rainwater to the ground prevents sea-water immersion into the fresh water bodies in the coastal areas.
• It helps in controlling urban flooding if people do rainwater harvesting from rooftops.
• It reduces water demands of people from the municipality thus lessens energy consumption too in distributing water all through the city.

Rain Water Harvesting Essay 3 (200 words)

Rainwater harvesting means collecting the rain water into the natural reservoirs or man-made tanks. It is the technique to collect and store rainwater for various purposes in the future. The most common and easy method of rain water harvesting is the rooftop harvesting. Using this technique we can collect lots of clean rain water in the rainy season. It can be stored for long time for the household purposes like gardening, livestock, and irrigation, etc. Following are benefits of rain water harvesting:

Rain Water Harvesting Essay 4 (250 words)

Every drop of rain water is like blessings of God to the people on the earth. Fresh rain water falls on the ground like pearls, so everyone should understand the importance of rain water especially in developing regions and rural areas lack of natural water resources.

We should try to collect rain water without wasting through rooftops and along streets run off. We should bring our old traditional harvesting practices using new and effective technologies to make easy water supply in all the regions. As only hand pumps, wells, and other resources of groundwater levels cannot fulfill the potable water need of hundreds of thousands of people.

Rainwater harvesting is the most sustainable and effective way for many years to make water available in the areas lacking water. Rainwater harvesting is very low cost method along with lots of benefits. It helps in various purposes like household works, field irrigation, livestock, agriculture and animal husbandry.

It helps in rejuvenating the groundwater levels in both directly and indirectly manner. Groundwater level can be replenished by rain water harvesting methods of trenches, anicut, dug wells, contour, etc whereas other rain water harvesting methods like underground water tanks, ponds, etc help in reducing the use of groundwater for at least four to six months. It is very effective in the hilly regions and desert regions of the India and other countries. More and clean rain water can be collected in the rainy season by making large and clean water body.

Rain Water Harvesting Essay 5 (300 words)

Now-a-days, people have been depended on the government system of water supply for getting water for their every need. The present scenario of water management and distribution in the cities has been centralized by the government which has brought a big gap of community responsibility in water management. It has slowly but regularly finished the old traditional water harvesting system.

Rainwater harvesting is again a new but old and effective technique of collecting rain water during rainy season for future usage purpose. It is being frequently used in various places of India to overcome the problems of lack of water. Rain water harvesting is the good source of ground water recharge in natural way.

However, the ground water level is getting less day by day because of the rapid urbanization and cities development at huge level as well as reduction in percolation of the rainwater to the ground. Rainwater harvesting is the way to reduce the use of ground water as well as maintain its level forever in the future. It is of more importance to the drought regions of India and other countries to supply the demands of water for various purposes. Following are mentioned points proving the fact why to harvest rainwater:

• It plays great role in protecting the ground water decline and improving the ground water table.
• It helps in improving the water quality in aquifers.
• It is to conserve more water and prevent surface water runoff during the monsoon.
• It helps in reducing the soil erosion.
• It is to bring the old tradition of water conservation among people.

Rain water can be harvested in better way using following methods like surface runoff harvesting and roof top rainwater harvesting. Both are very effective methods help in enhancing the level of ground water and fulfill the need of water supply in easy and cost effective way.

Rain Water Harvesting Essay 6 (400 words)

Rainwater harvesting is the collection and storage of rain water in the natural resources or artificially designed resources to prevent water runoff and fulfill the lack of water in future. The quantity of water harvesting is affected by the number of factors like frequency of rainfall, quantity of rainfall, way of collecting rain water, and size of resources to collect water. The ground water level is getting depleted day by day due to various reasons like deforestation and ecological imbalance.

Increasing level of urbanization and industrialization constantly increases the demand of water supply especially in the urban areas. It results in the overuse of ground water and thus going low level. The risk of water scarcity in the future has been increased to a great extent and can be life threatening if some effective solutions are not followed.

Water harvesting is very helpful and fulfill various need like recharging the ground water level, reduces electricity bill spend in supplying water and provide easy water supply anytime when required. It is estimated that 1 meter rise in the water level saves around 0.4 KWH of electricity.

Why Rain Water Harvesting is Necessary:

Rain water harvesting is very necessary to be practiced by the people in all regions. It is good to reduce the fear of water scarcity in the future. Following are the points proving the fact that why rain water harvesting is necessary:

• Surface water cannot fulfill the demand of water for various purposes.
• Everyone depend on the ground water for their every need.
• Deforestation, rapid urbanization, rain water infiltration to the sub-soil, etc reasons are continuously decreasing the level of ground water.
• Rain water conservation maintains the level of water in natural water resources.
• It reduces the chance of flooding of water on the roads, reduces the risk of soil erosion and improves the quality of water.

Following are main techniques of rain water harvesting:

• Collecting rainwater to the surface for future use.
• Recharging the ground water.

Collecting rain water to the surface is very effective and traditional technique. It can be done using small ponds, underground tanks, dams, weirs etc. However, ground water recharging technique is a new concept of harvesting. It can be done using dug wells, pits, trenches, hand pumps, recharge wells, recharge shafts, recharge lateral shafts with bore wells, spreading technique (means spread of water to the stream, nala, etc).

Rain Water Harvesting Essay 7 (800 words)

Introduction

Rainwater Harvesting is a method of storing rainwater, to be used in several domestic and agricultural activities. The basic idea is to not let the rainwater runoff and get wasted, rather to collect it by simple mechanism so that it can be used during scarcity of water. In the following essay we will explore the importance of rainwater harvesting, its methods and systems and how it is traditionally done in rural India. Below is a complete Essay on Rainwater Harvesting with Subheadings/Subtitles and Conclusion.

Rainwater Harvesting Methods/Rainwater Harvesting System

Primarily there are two types of rainwater harvesting methods as classified below-

1) Surface Runoff Harvesting

Surface runoff is a term used for precipitation that falls on the surface of earth and is subsequently lost to the environment. If elaborate arrangements are made to collect surface runoff water by providing it a path into a pond or tank; gallons of water could be stored to be used for several activities.

If designed efficiently, a system to collect surface runoff water can collect huge quantities of runoff from roads, parks, and gardens etc enough to sustain a small community or even a city. However, runoff water contains impurities; therefore, it must be passed through filtration process before it could be reused.

2) Roof Top Rainwater Harvesting

In roof top rainwater harvesting, the roof of a house or building functions as a catchment area for collecting rainwater. The water falling on the roof is diverted through a network or pipes to the desired pit or tank. It is by far the most economical and easy method of rainwater harvesting.

Houses or buildings with sloping roof can install gutters on the edges to collect the falling rain and to carry it to the destination using pipes or artificially created ditch. Though, care must be taken to flush out the water collected from first rain as it contains soluble impurities.

Rainwater Harvesting in India

In some places in India, still very traditional and ancient methods of rainwater harvesting are followed. These methods have proved successful in past and are still used in rural as well as urban India. Some of the significant traditional methods of rainwater harvesting in India are listed below-

This traditional method of rainwater harvesting is followed in tropical belt of southern states of Karnataka and Kerala. These regions are rich in laterite soil with naturally occurring depressions with three high sides. The three sides automatically function as the catchment area for collection of water in the depression. A small dam is constructed on the low lying fourth end of the depression to contain the runoff.

2) Surangaas

Surangas are traditional water harvesting system only used in Kasargod district of south Indian state of Kerala. The soil found in this region is hard laterite which is favorable for the construction of suranga (cave). Suranga is like a horizontal cave excavated in hilly terrain of the area, through which water oozes out and is thus collected in a pond. Though, this method is locally being used since centuries, it is sadly now gradually being replaced by bore wells.

Taankas are part of a traditional rainwater harvesting method practiced in the western state of Gujarat. Taankas are basically underground reservoirs with a capacity of storing thousands of liters of rainwater. Presently there are around ten thousand household in Gujarat’s capital city of Ahmadabad those are using taankas to meet their everyday water requirements. Water stored in a taanka is sealed against sunlight and therefore remains fresh for years.

Importance of Rainwater Harvesting

Rainwater harvesting provides an independent source of water supply during the scarcity of water. It becomes more valuable in context to the places where rain is scarce and uncertain. Also, in areas where fresh water is a costly commodity, preserving rain water is more economical option. Rain water thus preserved can be used to meet several household requirements like – washing and cleaning, gardening etc.

In case of unforeseen natural calamities like famine and droughts, rainwater harvesting might prove to be a blessing for the sufferers. Another significance of rain water harvesting is that it reduces the demand of water from other natural resources like wells, ponds and lakes, thus, preventing their depletion.

Water is most essential and precious resource, necessary for life on the planet. It can’t be wasted and every drop of it must be preserved to be reused in need. Rains on the other hand are vital source of fresh water, only if we have elaborate arrangements to collect it. Here, begins the concept of “Rainwater Harvesting”. Every year we lose thousands of liters of rainwater due to the lack of awareness about rainwater harvesting. It’s high time that we realize its usefulness to the nature and to the society as well and start implementing it in our house, buildings, parks, for a safe and water abundant future.

Introduction

Rainwater Harvesting is a method of storing rainwater, to be used in several domestic and agricultural activities. The basic idea is to not let the rainwater runoff and get wasted, rather to collect it by simple mechanism so that it can be used during scarcity of water. In the following essay we will explore the importance of rainwater harvesting, its methods and systems and how it is traditionally done in rural India. Below is a complete Essay on Rainwater Harvesting with Subheadings/Subtitles and Conclusion.

Rainwater Harvesting Methods/Rainwater Harvesting System

Primarily there are two types of rainwater harvesting methods as classified below-

1) Surface Runoff Harvesting

Surface runoff is a term used for precipitation that falls on the surface of earth and is subsequently lost to the environment. If elaborate arrangements are made to collect surface runoff water by providing it a path into a pond or tank; gallons of water could be stored to be used for several activities.

If designed efficiently, a system to collect surface runoff water can collect huge quantities of runoff from roads, parks, and gardens etc enough to sustain a small community or even a city. However, runoff water contains impurities; therefore, it must be passed through filtration process before it could be reused.

2) Roof Top Rainwater Harvesting

In roof top rainwater harvesting, the roof of a house or building functions as a catchment area for collecting rainwater. The water falling on the roof is diverted through a network or pipes to the desired pit or tank. It is by far the most economical and easy method of rainwater harvesting.

Houses or buildings with sloping roof can install gutters on the edges to collect the falling rain and to carry it to the destination using pipes or artificially created ditch. Though, care must be taken to flush out the water collected from first rain as it contains soluble impurities.

Rainwater Harvesting in India

In some places in India, still very traditional and ancient methods of rainwater harvesting are followed. These methods have proved successful in past and are still used in rural as well as urban India. Some of the significant traditional methods of rainwater harvesting in India are listed below-

This traditional method of rainwater harvesting is followed in tropical belt of southern states of Karnataka and Kerala. These regions are rich in laterite soil with naturally occurring depressions with three high sides. The three sides automatically function as the catchment area for collection of water in the depression. A small dam is constructed on the low lying fourth end of the depression to contain the runoff.

2) Surangaas

Surangas are traditional water harvesting system only used in Kasargod district of south Indian state of Kerala. The soil found in this region is hard laterite which is favorable for the construction of suranga (cave). Suranga is like a horizontal cave excavated in hilly terrain of the area, through which water oozes out and is thus collected in a pond. Though, this method is locally being used since centuries, it is sadly now gradually being replaced by bore wells.

Taankas are part of a traditional rainwater harvesting method practiced in the western state of Gujarat. Taankas are basically underground reservoirs with a capacity of storing thousands of liters of rainwater. Presently there are around ten thousand household in Gujarat’s capital city of Ahmadabad those are using taankas to meet their everyday water requirements. Water stored in a taanka is sealed against sunlight and therefore remains fresh for years.

Importance of Rainwater Harvesting

Rainwater harvesting provides an independent source of water supply during the scarcity of water. It becomes more valuable in context to the places where rain is scarce and uncertain. Also, in areas where fresh water is a costly commodity, preserving rain water is more economical option. Rain water thus preserved can be used to meet several household requirements like – washing and cleaning, gardening etc.

In case of unforeseen natural calamities like famine and droughts, rainwater harvesting might prove to be a blessing for the sufferers. Another significance of rain water harvesting is that it reduces the demand of water from other natural resources like wells, ponds and lakes, thus, preventing their depletion.

Water is most essential and precious resource, necessary for life on the planet. It can’t be wasted and every drop of it must be preserved to be reused in need. Rains on the other hand are vital source of fresh water, only if we have elaborate arrangements to collect it. Here, begins the concept of “Rainwater Harvesting”. Every year we lose thousands of liters of rainwater due to the lack of awareness about rainwater harvesting. It’s high time that we realize its usefulness to the nature and to the society as well and start implementing it in our house, buildings, parks, for a safe and water abundant future.

Rainwater harvesting is the method of storing and utilizing rainwater for further purposes. It is a good method of water management. This method is very essential in arid and desert areas where people usually face a shortage of water. Rainwater harvesting is a method with low capital and high benefits. It is also helpful in preserving the groundwater level.

Rainwater harvesting helps in fulfilling the water requirement of the society. Using this method, no water from the rain gets wasted. People can perform rainwater harvesting either by collecting water on the rooftop and then transferring it into underground tanks or by collecting surface runoff water in the ponds. Both methods are highly effective to collect rainwater. It also saves us from soil erosion, drought, and floods. Rainwater harvesting is an eco-friendly method of saving water that also controls the water cycle in the environment.

However, rainwater harvesting does have some limiting points. This method is only applicable to areas that receive a good amount of rain. Rainwater harvesting remains of no use in areas with low rain. Another thing is maintenance. Due to continuous water storage, there can be a chance of the production of algae and dangerous insects. Therefore, proper maintenance is necessary. Sometimes, rainwater harvesting can suffer a storage problem. Limiting storage can fail to store high rainfall.

Long Essay on Rainwater Harvesting (500 – 600 Words)

Introduction

There are number of countries that are facing water scarcity. Water scarcity is a global problem that the world is fighting. In some places, people don’t have any water resources they are mainly dependent on rain as the source of water. But rains are not permanent, and hence they made a technique to store them. Using this technique they can store water and later can use it for different purposes.

Rainwater Harvesting – a solution to water shortage

Rainwater harvesting is a technique through which water from rain is collected and stored. Through rainwater harvesting, water can be collected in man-made tanks or natural resources like ponds and reservoirs. The collected water can later be used for activities like irrigation, toilet purpose, gardening, etc. This method prevents rainwater from runoff. This method is very useful in places with a lack of water supply.

Rainwater is fresh and can be stored to perform small household activities. This process also helps in maintaining the ground level of water. This easy to perform method is not a new concept. People are practicing rainwater harvesting since ancient times.

Importance of Rainwater Harvesting

Rainwater harvesting helps to collect water for a different purposes without any cost. There are many advantages of rainwater harvesting. Some of them are:

• Cost-free: We can get water without paying any cost just by practicing rainwater harvesting.
• Effortless method: This method does not involve any hectic procedure to save water. Just by building tanks, we can collect water.
• Good solution: This method helps us to save water and fight the problem of arising water shortage.
• Maintains the balance: Rainwater harvesting removes the dependency of people on the groundwater. It also helps in maintaining the ecological balance.
• Reduces floods: Performing rainwater harvesting in every house can reduce the chances of natural disasters like floods. 
• Reduces soil erosion: The threat of soil erosion can be removed by performing rainwater harvesting. This method improves the water quality and balances the water cycle.

Rainwater Harvesting Methods

Rainwater harvesting is a successful method of collecting water that is performed in many places. There are two basic methods of carrying out this process. They are:

• Rooftop harvesting: This is the easiest and most convenient method of performing rainwater harvesting. In this method, the roofs of the houses are made in such a way that the rainwater gets collected. This water is then transferred to the underground tanks through pipes. Roofs of some houses are made slope and the edge is then connected to the tank where water gets collected. This stored water can now be used for many household purposes. Many people prefer this method of rainwater harvesting.
• Surface runoff: Another method of rainwater harvesting is to collect surface runoff water which gets lost in the environment if not collected. In this method, certain arrangements are made that provide a path to collect rainwater from parks, roads, small cities, etc to the tanks or ponds. Gallons of rainwater can be collected through this method. However, water collected through this method contains impurities and needed to filter before use.

Every single drop of water is precious still every year fresh rainwater goes wasted due to a lack of proper knowledge. There are many places where people are not aware of methods like water harvesting. Government should raise awareness and educate people regarding rainwater harvesting in the locality with water problems. This would really help them to fight the problem of water shortage and live life happily.

I hope the above given essay on rainwater harvesting will be helpful for you to understand the importance and procedure of this method.

Rainwater Harvesting and its Importance | Essay | PDF

December 26, 2017 by Study Mentor Leave a Comment

Rainwater harvesting is a strategy of collection and storage space of rainwater into natural reservoirs or tanks, or the seepage of surface water into subsoil water channels.

It is one of the purest form of water found on earth, because it is collected after it has vaporized and is almost as good as distilled water. Usually people in the rainfall-prone areas like Tamil Nadu, and parts of northeastern and even north-western India where there is a scarcity of potable water.   

Technicalities of Rainwater Harvesting  

Rainwater harvesting is perhaps one of the easiest methods of obtaining water. It does not require extensive knowledge, technical skills or cumbersome machinery. Expense-wise too, it’s extremely affordable.

All it requires is a waterproofed structure within the ground or over the ground that can hold the water during rains and prevent its loss as seepage. Some people employ plastic tanks which are connected by means of pipes to collection pans.

Rainwater harvesting is also done in many homes where they channel the rainwater collected from the roof drain pipes into a waterproof tank. This water can be used for plants as well as for basic washing. With minor filtration, it can be an excellent source of drinking water.  

Table of Contents

Why is Rainwater Harvesting Practiced?

Rainwater harvesting is a very ancient technique. It is mainly helpful in:  

• Areas where ground water table is quite low and it’s not feasible to draw clean ground water.  
• Areas where salinity of waterbodies have gone beyond the salinity threshold for plants to survive.  
• Regions with scarce and erratic rainfall.  
• Where indiscriminate use of chemicals have rendered the groundwater inadequate for use in crops as well as drinking.  
• It helps to reduce soil erosion too.  
• One of the major advantages of rainwater harvesting is that it doesn’t require a huge amount of land to be functional  

In this situation extremely important to cultivate the practice of rain water harvesting. During the last fifty years, the number of industries in India has grown rapidly. But water pollution is concentrated within a few subsectors mainly in the form of toxic wastes and pollutants.

The effects of this water pollution are not only devastating to humans but also to animals, fishes, birds. Polluted water is unsuitable for drinking, recreation, agriculture, and industry.  

The high nitrate content in groundwater is mainly from irrigation runoff from agricultural fields. Waste water from manufacturing or chemical processes in industries contribute to water pollution. All these adversities can be effectively mitigated by the use of rainwater harvesting units.

Since rainwater is already evaporated, it negates the collected water to undergo any further treatment as the concentration of contaminants in it reduces significantly. So we can use the water as is.  

  In these scenarios, rainwater becomes an extremely crucial practice in cities like Delhi, Mumbai, Chennai, etc. where rainfall is extremely erratic and the population pressure and growing industrialization has contaminated the sources of available freshwater.  

Various techniques of Rainwater harvesting include

• Recharge Pit  
• Recharge Trench  
• Tube well  
• Recharge well  

In rural areas, the following techniques are mostly employed

• Gully Plug  
• Contour Bund  
• Percolation Tank  
• Gabion Structure  

Active Initiatives  

• In 2001, Tamil Nadu was the first State that mandated rainwater harvesting for every building.  
• The ground water level significantly improved after implementation of rainwater harvesting systems in Chennai as much as 50%.  
• Also in various districts of Rajasthan, rainwater harvesting practice has brought relief to many crops as well as the people.  
• The government is working on a master plan envisaging construction of about 23 lakh artificial recharge and rainwater harvesting structure in rural areas and 88 lakh in urban areas.  
• Countries like Sri Lanka have even drafted laws for rainwater harvesting, the Urban Development Authority (Amendment) Act, No. 36 of 2007.  
• In UK, rainwater harvesting systems have the potential to reduce the net consumption of water by almost half.  

  In this day and age of industrialization and modernization and, subsequently, pollution, the water around us is becoming more and more polluted every day, thus making rainwater harvesting an unavoidable reality.  

Rain water is not Fool-Proof

Although with its advantages in tremendously vast applications, there are a few disadvantages to rain water harvesting. Due to excessive vehicular as well as industrial pollution, the concentration of oxides of carbon, Sulphur, nitrogen increases exponentially.

These oxides combine with precipitation (mostly in the form of rainwater) and convert to their respective corrosive acids, like carbonic acid, sulphuric acid, suplurous acid, nitric acid, nitrous acid, etc.

These combine with the rainwater and when this collected rainwater is used to agriculture or drinking, grave consequences like paralysis in humans and rotting in crops appear.

In that situation, rainwater is further treated to get potable water out of it which not only increases costs but also makes the process cumbersome and reduces efficiency of the system as a whole.  

But still, with all these problems, too, rainwater harvesting remains an extremely sustainable source of resource management and conversation. Sustainability is the need of the hour in this ever growing world of industrialization and subsequent pollution. It’s where we live, so we better take care of it! Would you rather live in a polluted dump?

Rainwater harvesting is an extremely easy yet effective way of cementing a bright sustainable future for us and our generations to follow thus promoting biodiversity.

Essay on Rainwater Harvesting

Water is a precious resource that is indispensable for life on Earth. With the growing population and increasing demands for water, it becomes crucial to adopt sustainable methods to manage and conserve this vital resource. One such method that has gained prominence in recent years is rainwater harvesting.

What is Rainwater harvesting?

Rainwater harvesting is the process of collecting, storing, and using rainwater for various purposes. It involves the capture of rainfall from surfaces like rooftops, catchments, and other surfaces, and then directing it to storage tanks or reservoirs. This stored rainwater can be utilized for domestic, agricultural, and industrial purposes, providing a decentralized and eco-friendly water supply.

Rainwater Harvesting System Components

• Catchment Area: This is the surface from which rainwater is collected. It is typically the roof of a house or any impermeable surface.
• Gutters and Downspouts: These components help channel the rainwater from the catchment area to the storage facility.
• Filter: Filters are used to remove debris, leaves, and other contaminants from the collected rainwater.
• Storage Tank: The harvested rainwater is stored in tanks or reservoirs, preventing runoff and enabling its controlled use during dry periods.
• First Flush Diverters: These devices divert the initial portion of rainwater, which may contain pollutants, away from the storage tank.

Advantages of Rainwater Harvesting

• Water Conservation: Rainwater harvesting helps in conserving water resources by capturing and storing rainwater that would otherwise runoff and be wasted.
• Groundwater Recharge: The process aids in replenishing groundwater levels, preventing the over-extraction of water from aquifers and promoting sustainable groundwater management.
• Reduced Dependency on Municipal Supply: By utilizing harvested rainwater for domestic needs, there is reduced dependence on municipal water supplies, especially during water scarcity periods.
• Mitigation of Flooding: Rainwater harvesting reduces surface runoff, mitigating the risk of flooding during heavy rainfall.
• Cost-Efficiency: Once the initial investment is made in a rainwater harvesting system, the operational costs are relatively low, making it a cost-effective water management solution.
• Challenges and Solutions: While rainwater harvesting offers numerous benefits, there are challenges to its widespread adoption. These include the initial cost of installing a harvesting system, the need for public awareness, and potential water quality concerns. Addressing these challenges requires incentivizing rainwater harvesting, providing financial support, and implementing proper filtration systems to ensure the stored water’s quality.

Rainwater Harvesting Facts

• In 2001, Tamil Nadu became the first Indian state to make rainwater harvesting compulsory in every building.
• In 2019, Government of India initiated Jal Shakti Abhiyan (JSA), extending into 2021 also to improve water availability including groundwater conditions in the country including Rajasthan, Delhi and Haryana.
• “Jal Shakti Abhiyan: Catch the Rain” (JSA:CTR) was launched by the Hon’ble Prime Minister on March 22, 20221. In addition, under JSA:CTR, 10.65 Lakh water conservation/rain water harvesting works, 1.79 Lakh renovation works of traditional water bodies completed (as on 07.02.2022) in the country.
• The various rainwater harvesting schemes in India are ‘Mukhyamantri Jal Swavlamban Abhiyan’ in Rajasthan, ‘Sujalam Sufalam Abhiyan’ in Gujarat, ‘Jalyukt Shibar’ in Maharashtra, ‘Mission Kakatiya’ in Telangana, Jal Jeevan Hariyali in Bihar, ‘Jal Hi Jeevan’ in Haryana, ‘Neeru Chettu’ in Andhra Pradesh, and Kudimaramath scheme in Tamil Nadu.

Rainwater Harvesting Challenges

While rainwater harvesting systems offer numerous advantages, it’s essential to consider potential disadvantages and challenges associated with their implementation:

• Initial Cost: Installing a rainwater harvesting system can involve significant upfront costs, including the purchase of storage tanks, filtration systems, and associated infrastructure. This initial investment may be a barrier for some individuals or communities.
• Space Requirements: Adequate space is needed for the installation of storage tanks and other components of the rainwater harvesting system. In urban areas or on small properties, finding sufficient space for these structures can be challenging.

Rain Water Harvesting Essay In English - 1400 in words

Rainwater harvesting is a technique used to store and store rainwater by using different means of different resources for future use (eg agriculture etc.). Rain water can be collected in natural reservoirs or artificial tanks. The infiltration of surface water is another method of collecting surface water from subsurface aquifers before dissipating by flooding the surface.

Short and Long Essay on Rain Water Harvesting in English

Essay 1 (300 words).

Every drop of rain on earth is like a blessing from God for the people. Fresh rain water falls like pearls on the ground, so everyone should understand the importance of rain water especially in developing areas and rural areas lacking natural water resources. Efforts should be made to collect the rain water flowing on the roofs and along the roads without wasting it.

To make water supply easy in all areas, we should bring our old tradition of collecting water using new and effective techniques. Because only hand pumps, wells and other sources of ground water cannot meet the accessible water needs of millions of people.

Rain water harvesting has been the most sustainable and effective way for many years to provide water to water scarce areas. It is a very cheap way to collect rain water with many benefits. It is helpful for many purposes like domestic works, field irrigation, livestock, agriculture and animal husbandry etc.

Rooftop water harvesting is a way to collect rainwater. These methods are very important for people living in areas with less rainfall. In the absence of regular water supply, they can continue with the cultivation of seasonal crops with rainwater. Whenever it rains, rain water can be stored in a man-made pond or tank.

It helps in recreating the ground water level both directly and indirectly. Ground water table can be recharged by digging ditches, wells, collecting rain water in different sizes etc. Whereas, other methods of rainwater harvesting like water tanks, ponds etc. help in reducing the use of ground water level for at least 4 to 6 months. It is very effective in the mountainous and desert areas of India and other countries. More clean rain water can be collected during rainy season by making larger and clearer water sizes.

Essay 2 (400 words)

In today's days, people depend on the government system of water supply for all their water needs. The current scenario of water management and distribution by the government has become centralized in the cities, bringing with it a great deal of community responsibility in water management. It is slowly but regularly eliminating the old method of collecting water.

Rainwater harvesting is an old but effective technique of collecting rain water during the rainy season for various purposes in future. It is used repeatedly in different places of India to overcome the problem of water scarcity. Rain water harvesting is a good way to recharge the ground water level in a natural way.

However, the ground water level is depleting day by day due to rapid urbanization and development of cities on a large scale along with reduction in the infiltration of rain water from the ground. Harvesting rain water is a way to reduce the use of ground water as well as to maintain its level forever in the future. It is very important for drought prone areas of India and other countries to meet the demand of water for various purposes. It will be clear from the following points why to store rain water:

• This is to bring the old tradition of water conservation among the people.

Rain water harvesting can be done in a better way by using the following methods, such as keeping surface and roof water from flowing or wastage. Both the methods help in raising the ground water level and are a cheap and easy technique of water supply to meet various needs.

The following are the benefits of collecting rain water:

• It helps in reducing municipal water supply load and electricity bill, improving free water supply, crop production in rural areas, which leads to food security.
• Rainwater harvesting system helps in reducing domestic or personal insecurity in rural areas.
• It provides easy and low cost water supply in water scarce areas which helps in food security and income generation.

Tamil Nadu is the only state in India and will now be the first Indian state to collect rain water. The Tamil Nadu state government announced on 30 May 2014 that around 50,000 structures would be set up to collect rainwater at various locations in Chennai. As of now, around 4000 temples in Tamil Nadu have rainwater harvesting tanks which are also helping to recharge ground water.

Essay 3 (500 words)

Rainwater harvesting is the collection and storage of rain water through natural resources and artificially designed resources to meet the water scarcity in future and save water from flowing. The amount of water harvesting is affected by many factors such as the probability of rain, the amount of rain, the way rainwater is collected and the size of the resources to store the water. The ground water level is decreasing due to various reasons such as deforestation and ecological imbalance.

The demand for water supply is increasing especially in urban areas due to the ever-increasing urbanization and industrialization. The reason for this is excessive use of underground water, due to which it is going downhill. If some effective steps are not taken immediately, then in future the risk of water scarcity will increase on a large scale and it can also prove to be life threatening.

Water harvesting is very helpful it fulfills various needs such as recharge of ground water table, will reduce the electricity bill spent in water supply and will provide easy water supply at any time as and when it is needed. It is estimated that 1 meter rise in water level will save about 0.4KWH of electricity.

Why is rain water harvesting necessary?

Rain water harvesting is very important for the people of all the areas. It is very good to eliminate the fear of water scarcity in future. The following points will help in understanding why there is a need for rainwater harvesting:

• Surface water cannot meet the demand of water for various purposes.
• Everyone is dependent on ground water for all their needs.
• Due to deforestation, rapid urbanization, seepage of rain water from the soil below, the ground water level is continuously decreasing.
• Storage of rain water maintains the water level in natural water resources.
• It reduces the risk of flooding and soil erosion on the roads as well as improves water quality.
• Air Pollution Essay
• Animals Essay
• Abdul Kalam Essay
• Bal Swachhta Abhiyan Essay

The main techniques of rain water harvesting are as follows:

• To collect surface water for future use.
• Ground water recharge.

Rainwater harvesting from the surface is a very effective and traditional technique. This can be done using small ponds, underground tanks, dams, dams etc. However, groundwater recharge technology is a new method of storage. This can be done by digging well, pit, ditch, hand pump, recharge well.

The benefits of rainwater harvesting at individual or city level are as follows:

• This brings down the water supply bill especially the bills of the institutions.
• Rainwater gets re-charged into the ground by positively affecting ground water quality by reducing its salinity, fluoride, nitrates and fluoride.
• It has a near neutral pH and zero hardness which makes it suitable for extensive use in homes, industries, institutions and other commercial installations.
• This can reduce the concern of public water supply sources.
• The recharge of rainwater from the ground prevents seawater submersion in fresh water sources in coastal areas.
• It helps in urban flood control if people collect rainwater from rooftops.
• This will reduce the water demand of the people from the municipality, which will also result in less energy being spent on water distribution throughout the city.

There are different topics a speech can be written and delivered. Before the students learn to write a speech on rainwater harvesting and understand the content to be written there are a few crucial pieces of information the students need to learn to write an impactful speech. 

What is a Speech?  

Speech is a form of communication made by a speaker in front of an audience on a specific topic. A speech helps the speaker express their thoughts in spoken language. A speech can be formal or informal based on the nature of the topic of the speech. 

Types of Speech

Speech can be classified into four categories based on its purpose: 

Informative Speech- This type of speech is given by the speaker with the primary focus being passing on information. These speeches are knowledgeable and relevant to your audience as they share the same interest in the topic. For example, a teacher talks about the Hydrologic cycle of water.

Demonstrative Speech- This type of speech is a lot more like an informative speech. A demonstrative speech also has the primary focus of delivering information. The difference between informative and demonstrative speech is mainly that the demonstrative speech is used to give a demonstration about the “How”. 

For example, How to bake cookies? Even though it involves information on baking cooking it also gives you the step-by-step process of performing the task based on the information.

Persuasive Speech- This type of speech does not have information or demonstration. The primary focus of a persuasive speech is to influence one’s mind and make changes in their life. For example, Donate your eyes - this topic of speech persuades or convinces an individual of the act learned.

Entertaining Speech- This type of speech does not have any information, demonstration, or influence upon the audience. This type of speech is merely for keeping the audience hooked. For example, a compere at a wedding.

Tips on Preparing for a Speech

Some of the tips are:

Observe, analyze and understand your audience

Understand the type of speech and decide on the narrative accordingly 

Always be prepared with additional content 

The topic has to be based on your audience, the type of speech, and also based on the occasion. 

The speech has to be well constructed, that is the content has to be placed in an order. This makes it easy for the audience to connect and understand. 

An Overview of Rainwater Harvesting Speech  

Rainwater harvesting is the collection and storage of rainwater, instead of allowing it to flow away, for future use. The collected water is contained in percolating wells, shafts, etc. It is often used for drinking purposes and the extracted water can be used in irrigation, plantations, domestic use, etc. One of the oldest and easiest methods for storing freshwater is rainwater harvesting. Here we have provided a long speech and a short speech on rainwater harvesting for Classes 5 to 12 along with 10 lines for writing a speech on rainwater harvesting for Classes 1 to 4.

Long and Short Speech on Rainwater Harvesting

Long speech on rainwater harvesting.

Today, I am here to deliver a speech on rainwater harvesting. The climate is constantly changing, mostly due to changes in the atmosphere, resulting in an unprecedented rate of temperature change. The length of different seasons has also been altered.

The period of the rainy season and the winter season was shortened (less than 4 months), while the summer season was increased by more than 4 months. The amount of precipitation and its groundwater recharge has also been drastically decreased. In response, the groundwater systems such as tube wells, etc. have now begun to collapse at many locations.

People do not get water for their domestic needs; it becomes difficult to plant crops; reservoirs dry up, etc. In short, the lack of water is huge. The government is spending large sums of money to combat these issues.

The harvesting of natural water (rainwater) plays a very important role in this situation, diluting the problem of water shortages.

Different methods of water harvesting have been developed, which are in use worldwide for a very long time back. "As mentioned, few of the very earliest Middle East agriculture was focused on the diversion of "wadi" flow to agricultural fields, a kind of water harvesting and irrigation recycling of harvested water.

The water harvesting systems were reported to be used in the Negev desert (Israel) around 4000 years ago or more, where water harvesting was carried out by clearing the hillsides of vegetation to increase the runoff and directing the runoff to the fields on the plains.

Similarly, from at least 1000 years ago, floodwater farming has been documented in practice in the desert regions of Arizona and northwest New Mexico. The micro-catchment technique for tree growing was identified in southern Tunisia, which was discovered by travelers Pacey and Cullis (1986) in the nineteenth century.

The "Khadin" scheme in India, in which floodwater is impounded behind earthen bunds, and crops are planted in the field based on the residual moisture content due to impounded water infiltration.

Farmers have also documented the use of conventional and small-scale water harvesting systems in sub-Saharan Africa. The method of water harvesting is documented in some West African countries by constructing a simple structure using stones. The practice of water harvesting has been documented in Sudan and the Central Rangelands of Somalia through the construction of the Bund system.

There are different advantages and uses for rainwater harvesting; however, harvesting systems have to work and maintain to ensure water quality. Water has to be distilled and filtered for use as well. Rainwater should be collected by every person, so it can be used for other occupations. The water on the surface and roof should be protected from pollution as it helps to increase the level of groundwater.

Short Speech on Rainwater Harvesting

Today, I am here to deliver a speech on rainwater harvesting. Water harvesting is, in a broad sense, defined as the collection of runoff for its productive use.' It is possible to harvest rainwater (overland flow/runoff) from the roofs and ground surfaces or intermittent or ephemeral streams (watercourses).

A variety of methods of water harvesting are available for various applications. The efficient use of harvested water includes the growth of provisions for domestic and livestock feed, the supply of crops, the processing of food and trees, and the construction of water bodies for the cultivation of fish and ducks.

Water harvesting incorporates different methods or activities focused on the use of runoff from un-cropped areas to replace the cropped areas with the harvested water.

In addition, it is also important to store water for irrigation, domestic, or livestock use, but the use of harvested water for crop production is often given priority. In general, in arid and semi-arid areas where droughts occur very frequently and irrigation is not feasible, water harvesting is found to be very suitable.

While Water Harvesting in the Area Of Water Scare is Very Conducive to Crop Cultivation, the Rate of Adoption is Still Much Lower, for the Following Reasons:

Reluctance to preserve runoff areas that are clean and weedless.

High-cost participation.

Strong labor requirements for building and maintaining the facilities for water harvesting.

Small land availability for water-harvesting structure building.

In Addition to the Above Factors, There are also a Few Important Points that are Likely to Adversely Affect Water Harvesting:

High risk of damage to crops due to long-term stagnation of the area's water.

Increased risk of soil erosion and soil depletion in the catchment area.

Intensive soil erosion is possible in the region.

Rainwater harvesting can also be carried out on an industrial and household basis. You can provide your freshwater supply, reduce your water bill and make sure you never run out of water. All you need is sufficient equipment and knowledge of the rainwater harvesting process.

Lines for Speech on Rainwater Harvesting

Some of the lines are:

Rainwater Harvesting refers to the storage of rainwater in a pit or well that has been specially built for rainwater harvesting.

It is a mechanism in which the rainwater is not permitted to wash out, but is collected instead.

Rainwater irrigation, as it becomes scarce, is a way to sustain freshwater for summers.

The water obtained during the rainwater collection process is also passed through the percolation process.

Percolation is the process through which, before being processed, rainwater is passed through a natural filter system.

For many domestic and irrigation purposes, rainwater thus collected can be used.

The harvesting of rainwater also helps to recharge groundwater supplies.

Runoff water from the field is directed into specially built pits, wells, or tanks during rainwater harvesting.

The rainwater harvesting method has been used to conserve rainwater for decades.

Several ancient cities around the world were entirely dependent on rainwater harvesting.

FAQs on Speech on Rainwater Harvesting

1. What makes speech writing effective?

A speech is deemed to be effective if it conveys the core message of the speech. Students need to choose the core message of the speech wisely to be able to successfully deliver the speech. Research and understanding of the topic is an important element, once the student has researched and has a thorough understanding of the speech topic the same has to be planned in a structured layout to make an everlasting effect of the speech written and delivered.

2. What are the skills speech writing can develop?

Speechwriting can enhance a lot of skills in students. It allows students to think creatively and consider all different aspects of creating interest in the audience. Writing speech enhances critical thinking skills. It builds confidence in an individual and develops a personality. As a lot of research is involved in understanding the topic, students are able to improve their communication skills and at the same time develop the ability to research.

3. Where should you not use the Rainwater harvesting system?

Rainwater harvesting cannot be implemented in certain conditions where it is made out of asbestos sheeting. There is a possibility of unwanted and unsafe water being harvested if the rainwater harvesting system is installed. The water collected will be contaminated and not safe for human consumption as it could be caused to many health issues. The use of a Siphonic drainage system for collecting water from the roof can cause the flow of water through the pipe faster and result in faulty filtration. These are a few examples where it is best to avoid installing a rainwater harvesting system.

4. What are the components of a Rainwater harvesting system?

The rainwater harvesting system involves different components at various stages from transporting the rainwater through the pipes, filtering the water before storing it in tanks for reuse. There are 8 components involved - catchments, coarse mesh, gutter, conduits, first-flushing, filter, storage facility, and lastly recharge structure. All these different components have to function in order for the rainwater harvesting system to complete the entire process of using rainwater for reuse.

5. Why is rainwater harvesting an apt solution for densely populated regions?

Water scarcity has become a major problem in densely populated regions. These regions have a poor supply of water even for daily consumption. The industries also face shortcomings as the supply of water is of utmost importance in factories and companies to carry out basic functions. The scarcity of water is mainly faced during the dry season and hence adapting the rainwater harvesting system these regions can benefit by storing water for the dry season.

Thus, the concept of rainwater harvesting is also growing rapidly and people are playing their role in conserving the environment and utilizing this natural resource .

In this Rainwater Harvesting Essay , we described rainwater harvesting and its importance, its advantages of rainwater harvesting & much more.

Rainwater Harvesting Essay 100 words:

Rainwater harvesting refers to the accumulation and storage of rainwater for natural reservoirs or tanks or the infiltration of surface water to bring surface water to the surface for later reuse.

The rainwater harvesting is very important because it is a practice to prevent wastage of water and it is used in many ways.

There are several methods such as surface water collection system, harvesting roofing method, underground tank, dam, slope, barrage, water storage reservoir, trenches etc.

Harvesting water ensures and prevents the smooth supply of water in future.

Homeprettify provides information related to the home design, tips, tricks and materials required for home Improvement.

Essay on Rainwater Harvesting 150 words:

Rainwater harvesting refers to the collection and storage of water for reuse.

It can be used later for various purposes like irrigation, gardens, household purposes and livestock, instead of allowing it to exit the gutter; also can be used as drinking water and groundwater storage.

Rainwater harvesting improves water supply throughout the year; with fluctuating climate change and the elimination of groundwater storage, rainwater harvesting helps mitigate those effects.

This can help recharge groundwater storage and ensure water availability in scarce areas. Rainwater conservation is also practised in individual homes and apartments.

Although new methods and techniques exist for harvesting rainwater in modern times, it is a traditional practice followed in rural areas.

Rainwater is always useful at a time when there is less rain; can be used in many ways whether by traditional methods or with the help of new methods and technology.

Rainwater Harvesting Essay 300 words:

Nowadays people have become dependent on the federal government system of water to provide water for their every need.

The present situation of water management and distribution in cities has been centralized by the federal government which has introduced an enormous gap in group responsibility in water management.

This has gradually but regularly eliminated the outdated conventional water harvesting system.

Rainwater harvesting is an old and efficient approach for rainwater harvesting throughout future use.

It is commonly used in various locations in India to overcome water shortage issues.

Rainwater harvesting is an efficient source of groundwater to recharge naturally.

However, the groundwater level is reducing day-to-day resulting from rapid urbanization and development of cities on a large scale in addition to a discount on the quantity of rainwater.

Rainwater harvesting is the way in which to reduce groundwater use in addition to at all times preserve its degree sooner or later.

In the dry areas of India and different nations, it is extra necessary to fulfil the demand for water for various functions.

The following factors show the actual fact of rainwater harvesting:

• It performs a great role in stopping groundwater degradation and improving the groundwater table.
• This helps in improving the water high quality in aquifers.
• This is to preserve extra water and stop surface water runoff through the monsoon.
• This helps in decreasing soil erosion.
• This is to bring the outdated tradition of water conservation among many folks.
• Rainwater can be harvested higher using the next methods equivalent to floor runoff harvesting and rainwater harvesting above the roof.
• Both very efficient strategies help to extend the groundwater and meet the water supply requirement easily and cost-effectively.

Essay on Rainwater Harvesting 350 words:

Rainwater harvesting is the accumulation, storage, conservation, and filtration of rainwater in the future for drinking water or for many other uses; the stored rainwater has to be maintained regularly.

The main objective of rainwater harvesting is to collect rainwater from a large surface above and then transport it to the storage tanks through the distribution system.

Rainwater harvesting provides an independent supply of water during most water combinations, where clean water is expensive for people in rural areas, accumulated water will be a cheaper source of potable water and can be stored for a longer period.

This practice is common by people in independent residences and buildings.

In developed countries, accumulated rainwater is a source of supply and also reduces the cost of domestic water consumption.

In a fluctuating climate, a rainwater harvesting system helps to capture rainwater when it rains.

Most countries with unpredictable environments use rainwater harvesting as it is an economical and reliable source of salinity and salts-free clean water.

It complements the water supply and prevents water wastage.

Rainwater is used exclusively for irrigation facilities; soil ridges are made to trap rainwater and prevent slopes, providing enough water for crops to grow.

In future, dams and ponds can be constructed for storing large amounts of water for irrigation, retainiwallsall are provided to avoid landslides.

Rainwater harvesting reduces the effects of flooding.

Due to rainwater harvesting, less water is directed towards the sewer system and it reduces stormwater in freshwater bodies and also prevents pollution of water bodies.

In many areas, underground water sources are slowly sieving. Construction of deep wells is costly and can harm the natural environment.

Thus, this source of rainwater is reliable and effective, can be used when the groundwater supply is depleted.

Conclusion:

Rainwater harvesting has various benefits and uses; however, harvesting systems have to operate and maintain to ensure water quality. Water also needs to be purified and filtered for use.

Rainwater Harvesting Essay 400 words:

Rainwater harvesting is the collection and storage of rainwater in natural water or artificially designed sources to prevent water runoff and meet future water shortages.

The amount of water harvesting is influenced by factors such as the frequency of rainfall, the amount of rainfall, how rainwater is collected, and the size of the resources to collect water.

The groundwater level is falling day by day due to various reasons like deforestation and ecological imbalance.

Demand for water supply increases, especially in urban areas, due to the constantly increasing level of urbanization and industrialization. This is leading to overuse of groundwater and thus lower levels.

The risk of water scarcity has increased substantially in the future and non-adherence to some effective solutions can be life-threatening.

Water harvesting is very useful and caters to varied needs such as recharging the groundwater level, reducing electricity bills within the water supply and offering water supply anytime.

It is estimated that 1m increase in water level saves about 0.4 kWh of electrical energy.

Advantages of Rainwater Harvesting:

Rainwater harvesting by individuals is essential in all areas; It is sweet to reduce the concern of water shortage sooner or later.

The following factors show the actual fact why rainwater harvesting is important:

• Surface water can’t meet water demand for various functions.
• Everyone depends on groundwater for his or her each need.
• The groundwater level is continuously decreasing due to deforestation, rapid urbanization, rainwater infiltration into sub-soil, etc.
• Rainwater harvesting maintains the water level in pure water resources.
• It reduces the opportunity of water on roads, reduces the risk of soil erosion and improves water quality.

The following are the primary strategies of rainwater harvesting:

• Collecting rainwater on the floor for future use.
• Collecting rainwater on the floor is a very effective and conventional technique, this may be completed using small ponds, underground tanks, dams, weeds and many others; however, groundwater recharging techniques are a brand new concept of harvesting.
• This may be completed using dug wells, pits, trenches, hand pumps, recharge wells, recharge shafts, recharging lateral shafts with bore wells, and dispersion techniques.

Rain water harvesting essay 2 Models

Last updated Friday , 15-03-2024 on 11:06 am

Rain water harvesting essay, in this vital topic, we will learn about new information that we did not know before about water harvesting. This project is a process undertaken by the state or by individuals. The purpose of collecting rainwater is to be used for drinking.

There are several ways and means to harvest or store fresh water that falls through rain. And if you hear about this for the first time, you must follow what we will present below.

Rain water harvesting essay

Due to the lack of fresh water, humans tried to devise new ways to find and provide fresh water for drinking and irrigating plants. And in the rain water harvesting essay, we will talk in detail about this interesting work. Which a large number of people do. Where they can secure enough water to drink and water the pets that live with them in the house. This water is used to easily irrigate the land and cultivate all agricultural crops.

What is meant by water harvesting?

It is a process in which quantities of fresh water collect in a clean place, where it does not mix with dirt or any dust.

It can congregate at the top of the house or in a hole lined with rocks, which maintains its purity.

This process is called harvesting because it is similar to harvesting plants, where water is collected during the rainy season. This simulates the harvesting of different fruits in their ripening seasons. But harvesting water is by means of pipes and equipment that differs from harvesting plants and fruits.

What is this water used for?

Fortunately, the water that is collected after the rains is clean and fresh, which makes it easy to use it for all life requirements. It can be drunk and used in cooking and household chores.

It is possible to water the animals that people raise in the barn, such as cows and chickens. It is possible for the farmer to water all kinds of plants that he grows on his farm. This water is pure and suitable for any purpose.

When does water harvesting begin?

Ancient man knew this good way to collect water that accidentally fell from the sky. When people moved over plateaus and highlands, they suffered from a lack of water. Therefore, when it was raining, they would collect water and drink from it.

Then other civilizations knew and used this method, the most important of which were Greece and India, where they collected water in a designated tank. In other civilizations, water was collected in caves and between rocks.

Advantages of harvesting water?

Since the water collected by harvesting is clean, it is used for anything related to humans and animals. In our rain water harvesting essay, we will know that the collected water is used to increase groundwater.

And there are places that people want to turn into green areas. But it does not have enough water for agriculture.

Therefore, they collect rainwater in huge tanks, where they deliver water to the ground and reclaim it easily.

Preserving water from pollution

People must keep the water clean, as they store it in clean and unpolluted places. It must be kept clean during the storage period, as they cover it and prevent insects from infiltrating it. And preserve it from volatile dust until it is suitable for drinking.

But if the water is not preserved, it will be contaminated with many pollutants. These pollutants will spoil the water and make it unfit for human use. Because of water pollution, those who drink it will be infected with many diseases, some of which may be serious.

How is groundwater fed?

Sometimes the farmer wants to increase the amount of groundwater he uses for agriculture and drinking. Where the farmer connects connections prepared to deliver water to the groundwater. After the rainwater reaches and mixes with the groundwater continuously, the groundwater stock begins to increase significantly.

However, certain filters must be made in order to purify the water from impurities before it goes underground. Certain substances must be added in order to rid the water of harmful substances that have been mixed with it by mistake.

Purification of water from impurities

When rainwater is collected it is sometimes contaminated with impurities such as mud and wood. But it must be purified in order for humans to be able to use it for drinking and cooking. That is why filters are made to purify the water and add certain materials that purify and kill germs in the water.

Rain water harvesting defects

When the rainwater is harvested by non-specialized people, the water is contaminated with many pollutants that they do not know anything about. Among these pollutants are pesticides that are suspended in water and are difficult to get rid of. There are other pollutants such as bird droppings that fall into the water,

In  our rain water harvesting essay, we will know that water must be purified from its bad effect on human health.

Whoever collects this water must know how to purify it from toxic gasses and elements such as mercury and ionic compounds.

Methods for treating collected water

Chlorine and ozone gas are added, as these additives purify the water and kill germs. If the impurities are simple, the water is left for a while without any treatment until the impurities settle to the bottom and the water is filtered.

As for groundwater, it must be ventilated to get rid of the gasses trapped with it. A method such as interaction with oxygen may be used to purify the water from any plankton that would make it unfit for human use.

Keeping humans from dehydration

The rainwater harvesting and storage is of great benefit as the planet is subject to drought over multiple periods of time. But if people can store fresh rainwater properly, drought will not affect them later.

Drought is the lack of rain or lack of it for many years, which leads to the lack of any fresh water to irrigate the land.

Droughts have occurred several times over the past years. And if humans stored water, drought would not kill huge numbers of them.

We have finished presenting a rain water harvesting essay. In this article, we provided a lot of information about collecting rainwater and how to purify it from impurities. We learned about the uses of stored water and its importance to living organisms. Therefore, states must encourage all citizens to store drinking water and purify it if they are able to do so. Where we reduce the risk of dehydration and lack of drinking water.
