Short Speech on Rainwater Harvesting
Good morning everyone,
My name is Mohit Rajak, and today I am here to talk about something very important—Rainwater Harvesting. This is a method of collecting and saving rainwater so that we can use it later. It is one of the best ways to save water and protect our environment.
Every year, a lot of rainwater goes waste. It flows away on roads or into drains. But if we collect this water and store it in tanks or underground, we can use it for many purposes. Rainwater can be used for gardening, cleaning, washing clothes, and even for drinking if it is filtered properly. This helps in saving our groundwater, which is slowly going down in many places.
Do you know? According to a 2023 report by NITI Aayog, nearly 21 Indian cities like Bengaluru, Chennai, and Delhi might run out of groundwater very soon. That’s scary, right? But the good news is that rainwater harvesting can help solve this problem.
There are different ways to harvest rainwater. The most common one is collecting rain from rooftops using pipes and storing it in tanks. Some people even make small pits or recharge wells to send the water underground. This helps in refilling the water table.
Rainwater harvesting is not a new idea. In olden times, kings and villagers built stepwells, tanks, and ponds to store rainwater. Places like Rajasthan and Gujarat still have old water structures that show how smart people were even without modern technology.
The Indian government is also helping people adopt this method. Under the Jal Shakti Abhiyan, many schools, homes, and villages are now building rainwater harvesting systems. There is also the Amrit Sarovar Mission, launched in 2022, to make 75 water bodies in every district to store water and improve water levels.
Even in schools, we can start this by collecting rain from rooftops and using it to water gardens. It saves money and helps nature. If each home in a city collects rainwater, we can stop water shortages in many areas.
Let’s also not forget that using rainwater saves electricity, too. Water pumps use electricity to bring water from underground. But if we already have stored rainwater, we don’t need to pump water all the time.
Rainwater is free, clean, and natural. All we need is the will to save it. If we learn to save every drop, we are actually saving our future. So, let us all promise today that we will learn about rainwater harvesting and try to use it at home, school, or in our neighborhood.
Thank you so much for listening to me. Remember, every drop counts!

Long Speech on Rainwater Harvesting
Good morning respected Principal, teachers, and my dear friends,
Today I feel happy to speak on a very important topic that touches the life of every human being—Rainwater Harvesting. We all know that water is life. Every living thing—whether it is a human, animal, bird, or plant—needs water to survive. But even though we understand this, many of us still waste water without thinking. We leave taps open, we let water overflow, and we don’t care where our water is coming from.
In many parts of India and the world, people don’t get enough water to drink, cook, clean, or grow food. Some walk miles just to fill a few pots of water. In such a situation, harvesting rainwater can be a very smart and simple way to save water and use it when needed. It’s like storing water during rainy days so that we can use it later during dry days.
Let us understand what rainwater harvesting really means. It is a method or technique to collect, store, and use rainwater that falls on rooftops, roads, parks, fields, and other open areas. This water can be stored in tanks or allowed to go underground to refill the groundwater. This way, we don’t waste rainwater and can use it when there is no rain.
Now, you might ask—why do we need to do this? The answer is simple. We are using more groundwater than nature can refill. According to the Central Ground Water Board, about 70% of India’s groundwater is used for agriculture. That means farmers are using most of the water for growing food, which is important, but it also means that underground water levels are falling.
A government report in 2022 said that 256 out of 700 districts in India are facing water stress. That means nearly 1 in every 3 districts is running low on water. This is a serious problem. If we do not take steps now, many cities may run out of clean water in the coming years.
Rainwater harvesting helps in many ways. First, it reduces our use of underground water. Second, it lowers water bills because rainwater is free. Third, it prevents water from flowing into drains and causing floods. Fourth, it helps farmers during dry months. Fifth, it improves the level of groundwater, which is very important for handpumps and wells in villages.
You might be surprised to know that just 1,000 square feet of roof can collect up to 22,000 liters of water during one rainy season. That is enough to fill hundreds of buckets. If every home, school, hospital, and shop collected rainwater, we could save millions of liters.
There are many ways to do rainwater harvesting. The most common method is the rooftop system. Rainwater from roofs is collected through pipes and stored in tanks. It can also be passed through filters and stored underground to recharge wells. Other methods include percolation pits, recharge trenches, and check dams. These methods are used in cities and villages, depending on space and need.
Even in olden times, our ancestors were very wise. In places like Rajasthan, Gujarat, and Tamil Nadu, kings and villagers built stepwells, ponds, and tanks to collect and store rainwater. These structures are hundreds of years old and some still work today. Places like Jodhpur, Jaipur, and Bundi have beautiful water harvesting systems that show how much people cared about water even in the past.
Today, the Indian government is also doing a lot to promote rainwater harvesting. One of the big steps was the Jal Shakti Abhiyan – Catch the Rain campaign, launched in 2021. The slogan was “Catch the rain, where it falls, when it falls.” This campaign encouraged people to build rainwater systems before the monsoon. It helped in building lakhs of water structures in both rural and urban areas.
Another important scheme is the Atal Bhujal Yojana, started in 2019, to improve groundwater in water-scarce states like Rajasthan, Gujarat, Madhya Pradesh, Uttar Pradesh, Maharashtra, Haryana, and Karnataka. It supports farmers and local groups to manage water better and increase groundwater recharge.
In Chennai, rainwater harvesting is compulsory in all buildings. After the rule was implemented, the water table rose by 10 to 15 feet in just a few years. This shows that rainwater harvesting can really make a big difference if everyone follows it properly.
Schools and colleges also have a big role to play. A small tank connected to rooftop pipes can collect thousands of liters during the rainy season. This water can be used to water plants, clean classrooms, or flush toilets. This saves both water and money. It also teaches students the importance of conservation.
Let me give you an example. Suppose a school spends ₹5,000 per month on water. After installing a rainwater harvesting system, the water bill goes down to ₹2,500 per month. That means the school saves ₹30,000 per year. And the system cost can be recovered in just 1–2 years. That’s how helpful and affordable this method is.
Even small homes can use plastic tanks, pipes, and simple filters to collect water. Villages and towns can make ponds and rain gardens to store water. NGOs like Tarun Bharat Sangh and the Centre for Science and Environment (CSE) are helping people set up such systems in poor and dry areas.
But all this will only work if we all take part. Every child, parent, and teacher must understand that water is not unlimited. If we waste water today, we will suffer tomorrow. We must talk about rainwater harvesting in schools, in families, and in our local areas.
We can do simple things like:
- Asking parents to install rooftop systems.
- Making posters or holding rallies about water conservation.
- Planting trees, because they help the soil soak more rain.
- Fixing leaking taps and pipes at home or in school.
- Telling others why rainwater harvesting is important.
Let us remember that rainwater is clean, fresh, and free. Nature gives it to us every year. But if we don’t store it, it goes into drains or evaporates. If we collect it, we can use it for drinking, cooking, farming, cleaning, and more.
Let us not wait for others. Let us be the change. Let us become water warriors who protect every drop. A single drop may look small, but together, many drops make a river. Let us be responsible and take this message forward.
So, dear friends, I request each one of you to understand the value of rainwater and take action. It is not just about saving water—it is about saving life. Let us promise today that we will do our best to harvest rainwater and teach others to do the same.
Thank you so much! Jai Hind!

Rainwater harvesting means collecting rainwater and storing it for later use. When it rains, water usually flows away, but with this method, we save that water. It can be collected from rooftops, roads, or fields and stored in tanks or allowed to go underground to refill wells. This is a simple and smart way to use natural water without wasting it.
Rainwater harvesting is very important because it helps save water. In many places, people do not have enough water to drink or grow food. By collecting rainwater, we can reduce our need for groundwater. It also helps during dry seasons and protects us from water shortages in the future. Saving rainwater today means saving life tomorrow.
Rainwater harvesting works by collecting rain that falls on rooftops or open spaces. Pipes carry the water into a tank or a pit. Sometimes, the water is filtered before storing. It can also be allowed to soak into the ground to refill the underground water. This water can then be used for washing, gardening, cleaning, or even drinking if properly filtered.
Rainwater harvesting is used in many parts of India. In Chennai, it is compulsory for all buildings. In Rajasthan, old stepwells and ponds still help people collect rain. Villages in Gujarat, Maharashtra, and Madhya Pradesh also use small dams and tanks to save water. Schools, colleges, and farms are also using this method more and more.
There are many benefits. It reduces our water bills. It prevents floods in cities. It helps in farming during dry times. It raises the underground water level. It also makes us more self-reliant and saves water for the future. Even a small rainwater system at home or school can save thousands of liters every year.
The Indian government has started programs like the Jal Shakti Abhiyan – Catch the Rain, which began in 2021, and encourages people to collect rain “where it falls, when it falls.” Another important scheme is the Atal Bhujal Yojana, launched in 2019, to improve groundwater in 7 states. These schemes help people, especially farmers, set up rainwater systems.
