Long and Short Speech on Rainwater Harvesting
Speech on Rainwater Harvesting 1
Good Morning Esteemed Panelists and Respected Audiences – I welcome you all to the seminar on Rainwater Harvesting!
I, Rajesh Sharma – the chairman in Water Conservation Department of Jaipur, am your host for today. Rainwater harvesting is a very pertinent activity. It involves the collection as well as storage of rainwater into natural bodies or man-made reservoirs with a view to keep a check on the overflow of surface water. There is other method of rainwater harvesting known as rooftop harvesting. In rooftop harvesting, such surfaces as metal sheets, tiles and plastics, excluding pal leaf or grass can be used to impede the rainwater flow and provide our homes with premium quality water to drink and make possible perennial storage facility.
There are other uses that involve water for irrigation, garden, livestock, etc. Following are the reasons behind using the method of rainwater harvesting:
- It helps in improving the supply of water, production of food thereby eventually giving you food security.
- Rural areas or households that suffer from water scarcity do get benefitted from the systems of rainwater harvesting.
- As rainwater harvesting ensures constant supply of water, which in turn provides food security and in turn significantly contributes towards income generation.
Do you know which Indian state had first decided to make rainwater harvesting obligatory? It’s on May 30th, in the year 2014 that the Tamil Nadu state government declared to establish 50,000 channels of rainwater harvesting at different parts of the Chennai city.
Nearly 4,000 temples in the state of Tamil Nadu traditionally maintained water tanks which were used for different rituals. The tanks were more or less like natural aquifers and helped restore groundwater. Though over a period of years, many of those tanks were discarded and it was the overflowing mass of garbage and silt that replaced the water present in them.
Now, it is through relentless campaigns being run by voluntary organizations as well as department authority of water supply and use, the officials in Chennai have taken a decision to restore about 40 tanks in the major temples of the city. The endeavor is to convert such water tanks into drainage basins for rainwater harvesting.
Other than Tamil State, in fact other states of India should adopt this tool to ensure the availability of water in our households and for restoring underground water. There is an international network called RAIN being formed with a view to boost the availability of water for vulnerable regions in developing nations to children and women in particular by accumulating and storing rainwater.
Thus, this method proves to be immensely helpful to cope with the situation of water shortage or inadequate supply of water and provides sustenance to various activities that are not possible without water, such as irrigation, gardening, rearing the livestock, etc.
Now, I would request the panelists the take over the stage and share their valuable thoughts on the same and suggest some methods of bettering the system of rainwater harvesting and how this method can be best utilized.
Speech on Rainwater Harvesting 2
Respected Parents of all the Children and My Dear Friends – Warm Good Evening to one and all!
Before I begin with my speech on Rainwater Harvesting, let me first extend warm thanks to all the parents for coming together under one roof and making our event a success. As we have been taught in our school the benefits of rainwater harvesting, all the children decided to spread the knowledge amongst their families and friends and enlighten everyone about its benefits.
Rainwater harvesting is an interesting method to collect and store rainwater for such uses as landscape irrigation, animal rearing, gardening, etc. When the rain comes, we never make any efforts towards preserving that water. The water can be collected from different hard surfaces, like terrace and/or other artificial aboveground tough surfaces. If the climate is dry, such as that of in South Australia, the technique of rainwater harvesting can prove to be extremely beneficial for the environment.
There are many rural households that have to conserve all the water for their property and rainwater more often than not offers comparatively a better quality supply to the household than river, dams or bore water. Rainwater harvesting however is not only meant for rural regions as many urban households too are joined to a reticulated, treated (mains) source of water supply. This method of rainwater harvesting can considerably bring down the use of main water sources.
Now, the question that arises is what are the advantages of rainwater harvesting? It’s one of the major benefits is that it will help you bring down your water bills, secondly you will have an alternative source of water supply during the situation of water crisis and thirdly it will help you maintain your green, blossoming garden. Excessive dependency on climate as well as tank size is not right and so rainwater harvesting can help reduce the burden drastically on the main sources of water.
Rainwater harvesting also helps overcome the fear of storm water runoff; thus reducing the risk of local flooding or scouring of brooks. You can collect rainwater from various rooftops, based on what quality of rainwater is required. For instance, if rainwater for lawn or garden irrigation is required, then
- Collect it from any roof surface other than unsealed asbestos
- Make sure that all gutters are linked to the outlets
- Preferably attach a good screen of leaf to the gutters
- Use the outlets of gutter that can be adjusted at the bottom of the gutter
For other miscellaneous uses:
- Do not let vegetation to hang from the roof
- Clean the gutters as well as your roof before fixing the system
- Install a leaf screen made of good quality underneath the gutters or instead fix a leaf-shedding gutter.
For the purpose of drinking, please do not collect rainwater:
- From roof sections which may contain asbestos sheeting or lead flashing and from terraces which are painted. If you cannot avoid this then properly seal the surface and paint it with a good quality roof sealant and avoid collecting rainwater from the initial periods of rainfall after sealing.
- In regions where airborne pollutants exist from nearby activities, like chemical processing and crop-dusting.
Therefore, the above mentioned measures should be taken in order to make a safe use of rainwater. Now, I would request my other friends to come on stage and say a few words in this regard.
Speech on Rainwater Harvesting 3
Hello Friends – Warm Greetings to everyone and I, Samaksh Dutt, welcome you all to this awareness program on Rainwater Harvesting! Being a part of such awareness programs from past 2 years, I have been given this wonderful opportunity to talk on such pertinent issue and enlighten our people. Therefore, I sincerely expect cooperation from you all and hope that everyone will listen to me patiently.
Now, coming to the topic called Rainwater harvesting – even though it is such a key technique to save on water, still the majority of our population isn’t aware why and how it is being done and in what ways we can be benefitted out of it. If I were to explain the process of rainwater harvesting in simpler terms, I would say that it’s a process which involves gathering and storing of rainwater for domestic, agricultural as well as commercial usages. With the fast changing environment, growth of population and rise in global temperature, major shortage of water is being faced by the countries all over the world. The gradual reduction in water level is a serious cause of concern not only because it gives rise to a situation of water crisis, but also mainly because in coastal regions, it results in creating an imbalance in the salinity of the region.
Speedy industrialization and dumping of chemical produce into different water bodies, such as lake, rivers, etc cause tremendous level of pollution. This is indeed a global phenomenon and requires an urgent solution. The fresh water supply on our planet cannot be augmented. Therefore, an alternative solution has to be looked for and one such solution is rainwater harvesting.
Rainwater harvesting is an economical and easy way to handle such situation of crisis. As people are becoming environment conscious, the method of rainwater harvesting is gaining a huge momentum thereby making eco-conservation and fair utilization of natural resource possible. Falling water tables is rampant and many people in urban regions seek dependency on bottled water which is neither budget friendly nor dependable.
The significance of developing the rainwater harvesting technique is briefly mentioned below:
- The collected rainwater is often used for agricultural activities. The environment can be helped in getting rid of the situation of drought.
- The water requirement for feeding the animals can be met.
- The relentless demand of water can be met.
- The volume of the subterranean water can be raised.
- Wastage of flowing water through gutter, drain or any other water-cause can be prevented and harm to the water bodies in any form could be stopped.
- The volume of water can be increased and soil erosion could be avoided.
- Water-logging on thoroughfares and normal roads can be prevented and residences can be made secure from the danger of inundation.
In the end, all I would like to say is that it’s our hostile approach towards nature that has led to the pollution in water bodies and made them unfit for drinking or other uses. God has bestowed on us with abundance of natural wealth, but man has not been able to make a fair use of it and unfortunately neither they can be manufactured in the workshops. Currently, many countries in the world are facing water scarcity and are therefore resorting to this rainwater harvesting technique for their survival. So I request all of you to realize the seriousness of this issue and overcome it by adopting active measures.
Speech on Rainwater Harvesting 4
Good Afternoon Ladies and Gentleman – I welcome you all to our Save Water Campaign and urge everyone to develop seriousness towards the situation of water crisis. This threat is constantly looming on our heads and we cannot help, but face this issue bravely if we want our coming generation to thrive on this planet.
Since the name of our campaign is Save Water Campaign, my team members are here to spread awareness on water saving techniques. Water as we all very well know is a very important natural resource without which man cannot imagine his existence. But when this very natural resource which is a life-giving source is depleting fast, human survival has come under serious threat. The speedy drop in groundwater level is a major cause of concern.
Now, the question that arises is how to bring the situation under control? This can only be brought through such major techniques as Rainwater harvesting. This comparatively simple technique can bring a world of difference in our day to day lives and help us overcome the situation of water crisis. This technique can be used for both domestic as well as commercial purposes, the various methods of which are described below:
- Domestic Rainwater Harvesting
There are two major systems of domestic rainwater harvesting process, namely;
Pump Feed System – In this case, the tank is installed at a ground level or sometimes underground where a pump is then used to dispense water around the house. In fact, one can also choose to go for a combined pump as well as gravity system that transports the water to the top of one’s house and then to another tank where it can be kept before being used through pipes.
Gravity Feed Systems – Such systems are more often than not placed at the top of a house and make use of the gravity power to push water to various parts of the house. These do not require any other source of power like electricity. Water is accumulated on the terrace when the rain starts and is fed straightaway into the tank’s filter system.
- Water Butts
Water butts are often considered the simplest form of this harvesting technique. They are nothing, but big plastic containers for storing water from one drainage pipe or via natural rainfall and are mostly maintained in the house for use in garden to water the plants.
If in your house, there is a garden of decent size, then a butt can be really helpful in keeping a check on your water consumption from the mains. You can also pair these butts with a Rain saucer, which is like an upside down umbrella used to collect rainwater much more effectively and without any hassles in comparison with a gutter.
- Commercial Rainwater Harvesting
The difference that comes in for commercial purposes is in terms of size. The technology remains more or less the same and may be somewhat more hi-tech. If buildings are really tall then gravity feed systems will be the most feasible option because of the great pressure of water that can be produced.
- Miscellaneous Rainwater Harvesting Systems
The excess water from the gutters or rooftops can be collected and utilized. But this is not the latest development as the latest development is about making use of the porous paving for collecting water, including such systems which are really built underneath gardens and that offer a sustainable way of bringing down the amount of water bills.
I think I have said enough on this topic, now I will request my other team members to join me on stage and add to what I have said.
