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.

FAQs on Rain Water Harvesting

Q.1 Why is Rainwater Harvesting important?

A.1 Rainwater harvesting is important because we are facing water scarcity. Rainwater is an economical way to save water and prevent rainwater wastage.

Q.2 How can one harvest rainwater?

Rain Water Harvesting Essay

Rainwater harvesting involves the collection and storage of rainwater into the natural reservoirs or artificial reservoirs in order to prevent the surface water runoff.

Rainwater harvesting is a process of collecting and storing rain water for using it as a backup supply of fresh water to meet everyday domestic and agricultural requirements, especially when water becomes scarcely available. There are several methods by which we can collect rainwater flowing from our roof tops, ditches, gardens, fields, forests and other locations. These methods are discussed in detail in the following essays. Rainwater harvesting not only provides fresh water in difficult times but also prevent naturally occurring fresh water resources from drying up, by reducing the demand of water. Rainwater harvesting is the least we can do to maintain the supply of water and also to support life on earth.

Long and Short Essay on Rain Water Harvesting in English

It is very important topic on which students may be assigned to write essay or paragraph on the rain water harvesting. You can select any rain water harvesting essay given below according to the need and requirement.

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:

It helps in reducing water supply loads and electricity bills of municipality, improve free water supply, crop production in rural areas, and thus lead to food security.
Rain water harvesting system helps in reducing the insecurity of households or individuals in the rural areas.
It provides easy and low cost water supply in the lack of water areas thus helps in food security and income generation.

Tamil Nadu is one of the states of India and now has been first Indian state where rainwater harvesting has been mandatory. Tamil Nadu state government has declared on 30 th of May 2014 to establish around 50,000 rainwater harvesting structures at various places in the Chennai. Till now, approximately 4,000 of the temples in the Tamilnadu have rain water tanks serving at various rituals in temples and help in recharging the groundwater.

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.

Rainwater Harvesting Essay

Components of rainwater harvesting

Rainwater harvesting includes multiple components that pass through various stages such as filtration, storing the water in the tanks for further reuse and transporting the water through the pipes and drains. The first component is catchments which is the surface that directly receives the rainwater and then it is provided directly to the system. The second component is the coarse mesh stage which is attached to the basement to impede the passage of the debris. The third component is the conduit which drains the rainwater from the rooftop directly to the harvesting system. The fourth component is the filter which is of two types the sand water filter and the charcoal water filter. With the help of this filter, the suspended pollutants from the rainwater are removed that is collected over the roof. Before the water reaches the storage tank, the dirt and debris are completely removed.

Advantages of rainwater harvesting

Rainwater harvesting can save the future paucity of water mainly in arid regions. In other words, it can help as an effective tool in educating people about the water conservation and management process. The various advantages of rainwater harvesting are listed below as follows:

Rainwater harvesting helps in meeting the demands of water in times of crisis mainly during the summer season. In India, Tamil Nadu is the first state to have used rainwater harvesting. Moreover, rainwater harvesting is also used for non-potable purposes such as irrigation in the most arid areas.
The water supplied by the municipalities is now being replaced by rainwater. Thus the former needs no longer to bear the burden of supplying water to the houses.
Installing and designing rainwater reservoirs and collecting systems can help proving employment to people.
Another benefit of using rainwater as potable water is that it does not have many chemicals as it is the most disinfected form of water, unlike the water tread with chloramines by municipal corporations.

Conclusion:

In conclusion, it can be said that rainwater harvesting is one of the most significant and effective ways of conserving and sustainable forms of managing water. In 1992, the US government enacted the US Energy Policy Act whereby it encouraged the method of rainwater harvesting. Thus, rainwater harvesting extends opportunities to acquire more water conservation gains in future.

Rainwater Harvesting - Concepts - Chapter 3 Class 10 Geography - Water Resources - Geography

Last updated at April 8, 2024 by Teachoo

Many thought that given the disadvantages and rising resistance against the multi-purpose projects , the water harvesting system was a viable alternative , both socio-economically and environmentally .
In ancient India , along with the sophisticated hydraulic structures , there existed an extraordinary tradition of water-harvesting systems .
People had in-depth knowledge of rainfall regimes and soil types and developed wide ranging techniques to harvest rainwater , groundwater , river water and flood water in keeping with the local ecological conditions and their water needs .
In hill and mountainous regions , people built diversion channels like the ‘guls’ or ‘kuls’ of the Western Himalayas for agriculture.

Traditional method of rainwater - Teachoo.png

‘Rooftop rainwater harvesting’ was commonly practiced to store drinking water , particularly in Rajasthan .

Rooftop Rainwater Harvesting - Teachoo.png

In the flood plains of Bengal , people developed inundation channels to irrigate their fields .
In arid and semi-arid regions , agriculture fields were converted into rain fed storage structures that allowed the water to stand and moisten the soil like the ‘khadins’ in Jaisalmer and ‘Johads’ in other parts of Rajasthan .
In the semi-arid and arid regions of Rajasthan , particularly in Bikaner , Phalodi and Barmer , almost all the houses traditionally had underground tanks or tankas for storing drinking water .
The tanks could be as large as a big room ; one household in Phalodi had a tank that was 6.1 metres deep , 4.27 metres long and 2.44 metres wide .
The Tankas were part of the well-developed rooftop rainwater harvesting system and were built inside the main house or the courtyard.

Underground Tanka in Rajasthan - Teachoo.png

They were connected to the sloping roofs of the houses through a pipe .
Rain falling on the rooftops would travel down the pipe and was stored in these underground ‘tankas’ .
The first spell of rain was usually not collected as this would clean the roofs and the pipes .
The rainwater from the subsequent showers was then collected .
The rainwater can be stored in the tankas till the next rainfall making it an extremely reliable source of drinking water when all other sources are dried up , particularly in the summers .
Rainwater , or Palar Pani , as commonly referred to in these parts, is considered the purest form of natural water .
Many houses constructed underground rooms adjoining the ‘tanka’ to beat the summer heat as it would keep the room cool .
Fortunately in many parts of rural and urban India , rooftop rainwater harvesting is being successfully adapted to store and conserve water .
In Gendathur , a remote backward village in Mysuru, Karnataka , villagers have installed, in their households, a rooftop rainwater harvesting system to meet their water needs .
Nearly 200 households have installed this system and the village has earned the rare distinction of being rich in rainwater .
Gendathur receives an annual precipitation of 1,000 mm , and with 80 percent of collection efficiently and of about 10 fillings , every house can collect and use about 50,000 litres of water annually .
From the 200 houses , the net amount of rainwater harvested annually amounts to 1,00,000 litres .

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.

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.

It is an easy and efficient approach to lessen your dependency on municipal water supply and conserve water. Rainwater is useful for many things, such as drinking water, car washing, gardening, and irrigation. In this article, we will learn about an important project on this topic and know how to make this project for school. We will also learn the objectives and advantages of rainwater harvesting project.

Rain Water Harvesting Project

Rain water harvesting Project (RWH) is the practise of collecting and storing rainwater as opposed to letting it flow off. Rainwater is gathered from a surface that resembles a roof and directed to a container with percolation, such as a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or reservoir where it seeps down and replenishes the groundwater table. With the aid of nets or other instruments, dew and fog can also be gathered. Stormwater harvesting is different from rainwater harvesting since the runoff from roofs and other surfaces is often collected for storage and later utilization. Rain Water Harvesting Project recycled water can be used for irrigation, home use with correct handling, watering gardens and cattle, and domestic heating. A groundwater recharge or longer-term storage project may be undertaken with the gathered water.

Rainwater Harvesting Necessity

The lifeblood of our world is water. It satisfies human thirst, feeds crops, and maintains ecosystems. But fresh water is a scarce resource, and the expanding needs of the world’s population are placing enormous strain on this valuable supply. Rainwater collection has shown to be a clever and sustainable response to this problem. This article explores the idea of rainwater harvesting, including its significance, how it works, and the advantages it has for communities and the environment.

Rainwater Harvesting Project Definition

Rainwater harvesting Project Definition- One of the earliest and most straightforward ways to provide water for households on your own is through rainwater gathering, which has been practised for thousands of years in South Asia and other regions.

Rainwater Harvesting System for Irrigation

Rainwater Harvesting System in households

Rainwater Harvesting Project Explanation

Water is an abiotic element of the environment that is valuable and necessary. As a result of water body contamination and a lack of water conservation, we are currently facing a water shortage. This is where the rain water harvesting comes into play. Rainwater harvesting is the process of gathering and storing precipitation using artificially constructed systems that drain from naturally occurring or artificially created catchment areas, such as rooftops, compounds, rock surfaces, hill slopes, and artificially restored impervious or semi-pervious land surfaces. This harvesting technique is cost-effective and environment friendly. It even increases the water supply and reduces its demand.

Methods of Rainwater Harvesting Class 10

In general, there are two methods for collecting rainwater: rooftop and surface runoff collection. Rainwater harvesting is the practise of gathering and storing rainwater for on-site re-use rather than letting it flow off. The water that is kept in storage is used for a variety of tasks, including irrigation and gardening.

1. Surface Runoff Harvesting

2. rooftop rainwater harvesting.

It is a technique for gathering rainwater at its source. Rooftop harvesting involves collecting rainwater from a building or home’s roof by turning it into a catchment.

It can either be directed to a synthetic recharge system or stored in a tank. If used properly, this strategy, which is less expensive and very beneficial, contributes to raising the local groundwater level.

Project on Rainwater Harvesting Components

The project on rainwater harvesting mainly constitutes of the following sub-components:

1. Catchment

The catchment of a rainwater harvesting system is the surface that directly receives rainfall. It could be an open area that is paved or unpaved, a terrace, or a courtyard.

2. Transportation

Rainwater from the roof should flow through the ground and into water pipes or drains that go to the system for storing and harvesting it. Water pipes must be UV resistant and the appropriate capacity (ISI HDPE/PVC pipes).

3. First Flush

The first flush is a mechanism used to remove the water from the initial shower. To prevent the potential contaminants from the atmosphere and the catchment roof from contaminating the storable/rechargeable water, the first rain shower must be rinsed off.

Since concerns have been expressed that rainfall can contaminate groundwater, there is some uncertainty regarding roof top rainwater harvesting. If the right filtration mechanism is not used, there is a slight chance that this worry will come to pass.

a. Sand Gravel Filter

These are often used filters that are built from brick masonry and have pebble, gravel, and sand fillets. Wire mesh should be used to divide each layer.

b. Charcoal Filter

In-situ or in a drum can be used to create charcoal filters. The drum or chamber should be filled with pebbles, gravel, sand, and charcoal as depicted in the illustration. Wire mesh should be used to divide each layer. If there is any odour, it is absorbed by the thin layer of charcoal.

c. PVC –Pipe filter

PVC pipe in the lengths of 1 to 1.20 metres can be used to create this filter; pipe diameter depends on the size of the roof. For roofs larger than 1500 square feet, 8 inches dia. pipe should be utilised instead of six inches dia. pipe. Wire mesh separates the pipe into three parts.

d. Sponge Filter

It is a straightforward filter fashioned from a PVC drum with a layer of sponge in the centre. It is the simplest and least expensive type of filter, suited for homes.

Rain water Harvesting Project Aim

To determine whether rainwater harvesting systems in Panch Lok, Raj Nagar, Kavi Nagar, Kamla Nehru Nagar, and Shastri Nagar are feasible and designed appropriately.

Rainwater Harvesting Project Objectives

Finding the rainwater potential and its relationship with groundwater, calculating the runoff from different areas of the colony according to land use, calculating the number of recharging structures required for the colony, locating the various types of recharging structures, and proposing a design prototype for each zone and each land use are all goals of this study.

Water harvesting techniques include: Collecting rainwater from roofs and roadways; collecting runoff from nearby catchments; collecting seasonal floodwater from nearby streams; and conserving water by managing watersheds. Utilizing rainwater for home or agricultural purposes is a part of it.

Rainwater Harvesting Project Necessity

The majority of rain that falls on the surface has a tendency to evaporate quickly, leaving very little for groundwater replenishment. As a result, even for home usage, water is scarce in the majority of India’s regions. As a result, steps to ensure that rain falling over a region is absorbed as fully as possible through rainwater harvesting are required. These techniques include either storing the water for later use or recharging it into groundwater aquifers.

Rainwater Harvesting Project Benefits

Increases groundwater table.
reduces runoff that clogs drains and prevents roads from flooding.
enables self-sufficiency in water supply and helps replenish home water needs during the summer and times of drought.
It lowers the rate at which power is consumed when pumping groundwater. One metre of water level rise results in a 0.4 KWH reduction in energy use.
Rainwater collection has helped communities in desert regions where rainfall is scarce.

Rainwater Harvesting Project Disadvantage

If supplies aren’t cleaned/flushed before use, bird/animal droppings on catchment surfaces and guttering structures could pollute them.
Algal development and invasion by insects, lizards, and rats are two problems that can occur in improperly built water jars and containers. If they are neglected, they may serve as a breeding ground for disease vectors.

Rainwater Harvesting Project Conclusion

The natural resources are under a significant deal of stress due to the expanding population and the increased demand for water. There will soon be a shortage of water worldwide due to the rapid depletion of underground reserves. This issue can be resolved if artificial methods are used. The necessity for and solution for rainwater harvesting in the Indirapuram neighbourhood of Ghaziabad are described in length in this study. In addition to helping with flood control, rainwater collection also helps with pollution control and continuous water supply.

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.

Speech on Rainwater Harvesting

Introduction

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.

Essay Rainwater Harvesting

Introduction

We often tell our children that water is precious and that we must not waste it. But have you wondered how many gallons of water are wasted during the rains? We get torrential downpours in the rainy season, and this water is washed away without finding any actual purpose. Through the essay rainwater harvesting, we can teach children the importance and benefits of preserving rainwater.

Though it is true that rains nourish plants and trees and help in their growth, it is disturbing to note how much rainwater is run through the drains. Rainwater harvesting is a method of collecting and storing rainwater to use for later purposes. This method of conserving water is highly beneficial considering the situation of water scarcity that we are facing today. The following essay on rainwater harvesting PDF will briefly discuss it, and children will be able to easily write a short essay on rainwater harvesting.

Importance of Rainwater Harvesting

Water scarcity is the greatest concern now, and it is even assumed that the next war will be fought for water. Hence, it is vital to preserve the water we get through the rain as it is essential for our sustenance. With the help of this essay on rainwater harvesting PDF, we will be able to understand the significance of rainwater harvesting.

Rainwater harvesting is a simple and the most economical way of water conservation . We find it difficult to meet our daily water needs if we rely only on surface water. Besides, most of the water we get is polluted, which adds to the problem of water scarcity. By harvesting rainwater, we can ensure that water will be at our hand’s reach to meet our demands.

The short essay on rainwater harvesting points out that the excessive use of groundwater by people leads to its shortage. Deforestation and urbanisation are also contributing factors to this problem. Hence, there must be an alternative solution to maintain the level of groundwater. Rainwater is the purest form of water, and it can be utilised for several purposes. Rainwater harvesting also prevents the logging of water on roads and soil erosion. Thus, the essay rainwater harvesting emphasises that rainwater harvesting is the best alternative to conserve water.

Methods of Rainwater Harvesting

Rainwater harvesting is a feasible and simple method that anyone can practise. In this part of the essay rainwater harvesting, we will see different methods of harvesting rainwater. We will also discuss surface runoff harvesting and rooftop rainwater harvesting methods in this short essay on rainwater harvesting.

In surface runoff harvesting, we collect the water that is runoff from the surface by making a pathway to a big storage tank. The water collected from roads, parks and gardens can be stored for a long period in large amounts, which can be later used for cooking or drinking after filtering properly. For rooftop harvesting, the roof of a house or building acts as a rainwater collecting and storage unit. The roof is fitted with pipes that collect rainwater and direct it to a tank. Instead of letting the rainwater fall on the ground, this method is convenient for conserving water.

Children will be able to realise the importance of rainwater harvesting through this short essay on rainwater harvesting. You can easily download the essay on rainwater harvesting PDF from our website. Apart from the essay rainwater harvesting, we have a lot more interesting content for kids learning .

Give two points of difference between 'surface water' and 'ground water'.

Question 1(c)

Give a geographical reason for each of the following:

(i) Need to adopt different means of irrigation.

(ii) Need for conserving water.

(iii) Man is responsible for water crisis in India.

(i) There is a need to adopt different means of irrigation because of uncertainty of rainfall, uneven distribution of rainfall, crop requirements, nature of the soil, effective utilisation of river water and to maximise production.

(ii) There is a need for conserving water for the following reasons-

The over exploitation of ground water often results in the lowering of water table.
The loss of vegetation causes drought and reduction of rainfall and lowering of the water table.
Irrigation utilises more than 90% of the total freshwater.
The increase in population results in water scarcity.
Our water resources are polluted and their water can hardly be used without adequate treatment.

(iii) Man is responsible for water crisis in India because due to increase in population, irrigation and industrialisation, the demand for water has risen. This has led to a decline in groundwater levels in various parts of the country.

Question 2(a)

What is meant by the term irrigation?

Irrigation refers to the process of watering of agricultural plants through artificial means from wells, tanks, tube wells, canals, etc.

Question 2(b)

What is meant by the term 'water scarcity'? What has caused this scarcity in India?

Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region.

Growing population, over-exploitation and unequal distribution of water among social groups are the main causes of water scarcity in India.

Question 2(c)

(i) Inundation canals are being converted to perennial canals.

(ii) Tank irrigation is preferred over other means of irrigation in Peninsular India.

(iii) Groundwater reserves are depleting at a fast rate.

(i) Inundation canals are being converted to perennial canals because inundation canals get supply of water only when the rivers are in flood while perennial canals can draw water throughout the year and irrigate large areas.

(ii) Tank irrigation is preferred over other means of irrigation in Peninsular India because-

The rivers of Deccan are mainly dependent on the rainwater.
Many streams become torrential during the rainy season but dry up when the rain ceases.
The hard rocks in the area do not absorb waters, wells cannot be made there.
The terrain is uneven with many natural depressions where tanks can be easily built.

(iii) Groundwater reserves are depleting at a fast rate due to increase in population, irrigation and industrialisation, the demand for water has risen. This has led to a decline in groundwater level in various parts of the country.

Question 2(d)

(i) What is meant by traditional or conventional methods of irrigation?

(ii) Name any two conventional methods of irrigation.

(i) Traditional methods of irrigation means to supply water to the plant zone by pumped water from surface or subsurface sources like ponds, rivers, channels or groundwater through earthen channels or pipes with gravitational force.

(ii) Two conventional methods of irrigation are wells and tanks.

Question 3(a)

State any two drawbacks of conventional methods of irrigation.

Two drawbacks of conventional methods of irrigation are-

A large quantity of water is not properly utilised.
The fields situated in low areas always get excess water causing prolonged water logging.

Question 3(b)

Give two advantages and two disadvantages of well irrigation.

Two advantages of well irrigation are-

Wells can be dug at a very low cost which is well within the means of poor farmers.
By the use of pumps and tubewells, water can be lifted even from great depths.

Two disadvantages of well irrigation are-

Wells depend on underground water resources whose distribution varies from region to region.
The traditional wells dry up due to over withdrawal of the ground water and lowering of the water table.

Question 3(c)

(i) Well irrigation is confined mainly to the alluvial plains.

(ii) In Tamil Nadu, nearly one-third of the net irrigated area is under canal irrigation.

(iii) Drip irrigation reduces loss of water through evaporation.

(i) Well irrigation is confined mainly to the alluvial plains as owing to the soft nature of the soil, wells can be easily dug and the yield of crops from the land after irrigation is considerably high.

(ii) In Tamil Nadu, nearly one-third of the net irrigated area is under canal irrigation because Tamil Nadu receives rainfall during the winter season while summer season remains dry. Thus, irrigation is needed in summer to make up the lack of rainfall.

(iii) Drip irrigation reduces loss of water through evaporation as this system consists of perforated pipes that are placed between rows of crops or buried along their root lines and give water directly on to the crops.

Question 3(d)

(i) Name any two states where well irrigation is practised.

(ii) Give one advantage and one disadvantage of tubewell irrigation.

(i) Two states where well irrigation is practised are Punjab and Uttar Pradesh.

(ii) One advantage of tubewell irrigation is that it brings up clean water. One disadvantage of tubewell irrigation is that it is useless if the water is brackish.

Question 4(a)

Name the two types of canals. Name two states where perennial canals are widely used.

Two types of canals are-

Two states where perennial canals are widely used are Uttar Pradesh and Madhya Pradesh.

Question 4(b)

How are the fields irrigated using the Persian wheel method?

Persian wheel method is a partly submerged vertical wheel with buckets attached to the rim. As the wheel is turned by draught animals rotating a geared horizontal wheel, the buckets are filled and emptied into a trough above, which carries the water to crop-sown fields.

Question 4(c)

(i) Canals make the soil infertile.

(ii) Tubewell irrigation is quite expensive.

(iii) Excessive accumulation of salts make the soils unsuitable for cultivation.

(i) Canals make the soil infertile because in canal irrigation, where water table is a few feet below the ground, the alkaline salts come to the surface, mix with the soil and make it unproductive.

(ii) Tubewell irrigation is quite expensive as it requires continuous supply of electricity.

(iii) Excessive accumulation of salts make the soils unsuitable for cultivation because when salt concentrations in the soil are high, the movement of water from the soil to the root is slowed down. When the salt concentrations in the soil are higher than inside the root cells, the soil will draw water from the root, and the plant will wilt and die. Hence, the soil becomes unsuitable for cultivation.

Question 4(d)

(i) Name two states in which tubewells are extensively used.

(ii) State why tubewell irrigation is important in Punjab.

(i) Two states in which tubewells are extensively used are Punjab and Haryana.

(ii) Tubewell irrigation is important in Punjab because it irrigates large areas of land in comparatively less time and it can irrigate the fields throughout the year.

Question 5(a)

What is meant by rainwater harvesting?

Rainwater harvesting is the process of increasing the recharge of groundwater by capturing and storing rainwater locally in sub-surface water reservoirs.

Question 5(b)

State any two methods of rainwater harvesting.

Two methods of rainwater harvesting are-

Question 5(c)

(i) Many farmers in India still use wells.

(ii) There is very little recharge of groundwater.

(iii) The traditional wells dry up.

(i) Many farmers in India still use wells because wells can be dug at a very low cost and the oxen which are kept for ploughing the land can be utilised for drawing water from the well.

(ii) There is very little recharge of groundwater as only a small amount of rain water runs down the earth surface and gets stored in the form of groundwater. So, only a small percentage of water gets down to the water table and forms ground water.

(iii) The traditional wells dry up due to the over-withdrawal of the groundwater and lowering of the water table.

Question 5(d)

(i) What is watershed management?

(ii) How is it beneficial for farmers in the long run?

(i) Watershed management refers to the efficient management and conservation of both the surface and groundwater resources. It includes the prevention of run-off as well as storage and recharge of groundwater by various methods like percolation pits, recharge wells, borewells, dugwells etc.

(ii) Watershed management is beneficial for farmers as it is aimed at conserving both soil and water. Since both soil and water are indispensible for the cultivation of crops, watershed management helps farmers to maximize their crop production and income.

Question 6(a)

What is 'drip irrigation'? How is it useful?

Drip irrigation is the most advanced and efficient method of irrigation. This system consists of perforated pipes that are placed between rows of crops or buried along their root lines and give water directly on to the crops.

It is useful as it reduces evaporation drastically and irrigation water is conserved. It also allows the grower to customise an irrigation programme most beneficial to each crop.

Question 6(b)

Explain briefly the need to conserve water.

We need to conserve water for the following reasons-

Question 6(c)

(i) Modern means of irrigation are gaining popularity.

(ii) Sprinkler irrigation helps in conserving water.

(iii) Spray irrigation is quite expensive.

(i) Modern means of irrigation are gaining popularity because of the following reasons-

No loss of water due to seepage or evaporation
Conserve water
Prevent soil erosion
Suitable for areas where the rainfall is low
High efficiency

(ii) Sprinkler irrigation helps in conserving water as water is sprayed directly to the required plants so there is no loss of water through seepage or evaporation.

(iii) Spray irrigation is quite expensive because it requires complex machinery.

Question 6(d)

What is meant by furrow irrigation? What is its advantage?

Furrow irrigation is a type of flood irrigation in which the water poured on the field is directed to flow through narrow channels dug between the rows of crops, instead of evenly distributing the water throughout the whole field. The furrows must have equal dimensions, in order to guarantee that the water is distributed evenly.

The advantage of furrow irrigation is lower initial investment of equipment and lower pumping costs per acre-inch of water pumped.

Thinking Skills

Nature has endowed India with plentiful water resources. Despite this, acute shortage of water is noticed in some states. What could be the reasons for this shortage?

India is known to be a land of rivers with 12 major rivers and 46 medium rivers. Many of these rivers are perennial and some of them are seasonal. The annual rainfall in India is 1,170 mm which is higher as compared to the world average of 800 mm. Despite this, acute shortage of water in some states is due to the following reasons:

Uneven distribution — Water resources are not distributed evenly across the country. The monsoons rains are also spread unevenly. The result is that some states are devastated with floods while others face severe drought at the same time.
Population growth — India has one of the world's largest populations, and the demand for water is increasing due to rapid urbanization, industrialization, and agricultural growth. India constitutes around 17% of the world's population but has only 4% of the world's freshwater resources.
Poor water management — Inefficient management of water resources, lack of proper infrastructure, and poor governance are also contributing to the water shortage in some states.
Pollution — Pollution of water bodies, such as rivers, lakes, and groundwater, is reducing the availability of clean water for domestic, agricultural, and industrial use.

In your city, critical shortage of water has been reported due to the sharp fall in the groundwater level. What steps you will take to check this scarcity of water?

To check this scarcity of water, we need to take quick steps to make proper policies and laws and adopt effective measures for water conservation. This can be done by using rainwater harvesting. It is the process of increasing the recharge of groundwater by capturing and storing rainwater locally in sub-surface water reservoirs.

Various kinds of recharge structures are possible which can ensure that rainwater percolates in the ground instead of draining away from the surface Some of these are:

Borewells and Dugwells — They are used to raise the underground water table.
Recharge Pit — They are excavated into the ground lined with a brick or stone wall with openings at regular intervals.
Percolation Pits — It is a bored hole of up to 30 cm diameter drilled in the ground to a depth of 3 to 10 m.
Recharge Trenches — They are excavated on the ground and refilled with porous media like pebbles, boulder or brick bats to harvest the surface runoff.
Permeable Surfaces — For example, a patch of grass is used to retain a large proportion of the rainwater falling on it, yielding only 10-15 per cent as runoff.
Porous tiles — They can be used on pavements and footpaths.

A number of water saving technologies have been developed in recent decades. Which one would you prefer to use in your area and why?

I would like to use rainwater harvesting technique to conserve water because the area where I reside receives adequate rainfall during the monsoon season. My locality is developed in such a way that every block has a big park with patches of grass and trees. The trees and grass minimize runoff.

The people of my area can collectively harvest rainwater on their rooftops and even use the parks for building various recharge structures such as borewells, recharge pits, percolation pits, recharge trenches, porous tiles on the pavement etc.

If you are given a choice between using traditional or modern methods of irrigation, which method you would prefer to use in your area and why?

I would prefer to use drip irrigation which is a modern method of irrigation because of the following reasons:

It is the most advanced and efficient method of irrigation.
This system consists of perforated pipes that are placed between rows of crops or buried along their root lines and give water directly on to the crops. As a result, evaporation is drastically reduced.
It helps to conserve irrigation water.
It allows the grower to customise an irrigation programme most beneficial to each crop.

(c) In Gujarat, the Sabarmati basin farmers were not agitated when higher priority was given to water supply in urban areas, particularly during droughts. (d) Today in Rajasthan, the practice of rooftop rainwater water harvesting has gained popularity despite high water availability due to the Rajasthan Canal.

Answer: (i) Not suffering from water scarcity Explanation: Regions with high annual rainfall cannot face scarcity of water because the water table is replenished, water bodies do not dry up so no water scarcity.

(ii) c) Multi-purpose projects lead to large scale displacements and loss of livelihood. Explanation: Multipurpose projects and large dams have also been the cause of many environmental movements like the Narmada Bachao Andolan and Tehri Bachao Andolan etc. Resistance to these projects has primarily been due to the large scale displacement of local communities. Local people often had to give up their land, livelihood and their meagre access and control over resources for the greater good of the nation.

(iii) (a) Multiplying urban centers with large and dense populations with urban lifestyles have added to the water and energy requirment and thus, caused the over exploitation of water resources. (b) Regulating and damming of rivers affect their natural flow and causes the sediment to settle at the bottom of the dam. (c) In Gujarat, the Sabarmati basin farmers agitated over the higher priority given of water supply in urban areas, particularly during droughts (d) Today in Rajasthan, the practice of rooftop rainwater harvesting is on the decline as plenty of water is available due to perennial Rajasthan canal.

Question 2. Answer the following questions in about 30 words. (i) Explain how water becomes a renewable resource. (ii) What is water scarcity and what are its main causes? (iii) Compare the advantages and disadvantages of multi-purpose river projects.

Answer : (i) Water is a renewable resource as it is renewed by water cycle itself, where three processes take place as evaporation, condensation and precipitation. This process of water cycle is never ending and hence, water is a renewable resource. The water then runs into rivers and dams where it is used and the waste is partially cleaned before it makes its route to the sea, where the cycle begins again. Freshwater is mainly obtained from surface runoff and groundwater that is continually being renewed and recharged through the hydrological cycle.

(ii) Water scarcity or water stress occurs when water availability is not enough to match the demand for water. It is caused by an increase in population, growing demand for water, urbanisation, industrialisation, wastage injudicious use and unequal access to it. A large population requires more water not only for domestic use but also to produce more food. The ever increasing number of industries has made matters worse by exerting pressure on existing fresh water resources. Fragile water resources are being over-exploited and have been depleted in cities. Water scarcity may also be due to the bad quality of water. Lately there has been a growing concern that even if there is ample water to meet the needs of the people, much of it may be polluted by domestic and industrial wastes, chemicals, pesticides and fertilizers used in agriculture, thus, making it hazardous for human use.

(iii) Multipurpose river projects help in irrigation, electricity production, flood control, the supply of water for domestic and industrial use, recreation, inland navigation and fish breeding. It integrates development of agriculture and the village economy with rapid industrialization and growth of the urban economy. However, the reservoirs destroy local flora and fauna. Dams fragment the river thus making it difficult for aquatic fauna to migrate and for spawning. Many native villages are submerged, and people lose their livelihood, with little or no hope of rehabilitation. The dams that were constructed to control floods have triggered floods due to sedimentation in the reservoir. It was also observed that the multi-purpose projects induced earthquakes, caused waterborne diseases and pests and pollution resulting from excessive use of water.

Question 3. Answer the following questions in about 120 words. (i) Discuss how rainwater harvesting in semi-arid regions of Rajasthan is carried out. (ii) Describe how modern adaptations of traditional rainwater harvesting methods are being carried out to conserve and store water.

Answer : (i) Houses in the semi arid regions of Rajasthan have traditionally constructed tanks for storing drinking water. The tanks could be as large as a big room. They are big and are a part of the well-developed rooftop rainwater harvesting system. The tanks are constructed inside the main house or the courtyard and are connected to the sloping roofs of the houses through a pipe. The rain falling on the rooftop travels down and is stored in the underground tanks. The first spell of rain is not collected as this water cleans the roof and the pipes. The rainwater from the subsequent spells is collected. This water is used untill the next rainy season and is a reliable source of water even after other sources have dried up. The tanks also help in cooling the houses as rooms built around them have generally low temperatures due to conduction.

(ii) Traditional methods of rainwater harvesting like ‘the rooftop method’ are becoming popular in India. In Gendathur village, Mysore, about 200 households have adopted the rooftop rainwater harvesting method, thereby making the village rich in rainwater. The state of Tamil Nadu has made it compulsory for all the houses to have rooftop rainwater harvesting structures There are legal provisions to punish the defaulters. Rooftop rainwater harvesting is the most common practice in Shillong, Meghalaya. Rooftop harvesting is common across the towns and villages of the Thar. In Meghalaya, a 200 year old system of tapping stream and spring water by using bamboo pipes is prevalent. About 18 to 20 litres of water enters the bamboo pipe system and gets transported over hundreds of metres.
