Rain Water Harvesting Paragraph 250 words
Rain water harvesting is the process in which the rain water is accumulated and stored for later use. Rain water harvesting has to be rightly used to keep the scarcity of water at bay. It is always wise to harvest rain water as its natural, clean and salt free source of water. However the quality of water has to be maintained depending on the end use.
Rain Water Filtration
The rain water can be purified, filtered and maintained in several ways. The catch area of rain water has to be cleaned and the pipes are to be flushed. Initially the flow of water can be diverted to run off water to waste. The floating draw-off mechanism can be used to obtain the improved quality of water. The presence of contaminants or any kind of waste can affect the quality of water. The contaminants may include air pollution, leaves, sand, dust, bird excrements, etc.
The filtration that removes the contaminants and purifies the water has to be done. The harvested rain water has to be treated and tested to ensure the quality. In industries the common practice used is pre-filtration to ensure the water directed to the tank is purified. The water supply system should meet the quality of water by applying preliminary filtration measures. Some methods of purifying the water are; solar sterilization, sediment filtration, use of chlorine or iodine, etc. The drinking water can also be purified through RO water purifier systems.
Thus, there are several ways in which water can be purified and has to be treated before use. Especially, when the water is to be used as drinking water it can’t be used without purification and filtration.

Rain Water Harvesting Paragraph 300 words
Water is one of the most important and basic needs for us and due to overpopulation and irregular rainfall, harvesting rain water is vital. Rain water harvesting is the technique used for collecting, storing and saving water for future use. When it rains the water pours off the roof top and runs down through the gutters or is directed towards the streets. With rain water harvesting water from the rooftops can be directed through pipelines or tubes in to the cistern or storage tank to save it for later use. Rain water is sustainable and high quality water source.
Rain Water Harvesting System
Rain water harvesting systems can be simple and complex. In residential areas the rain water harvesting is done with simple plumbing work as terrace is connected with a pipe directed to underground tank. The storage capacity of the underground tank is ideally sized to meet the need of daily water consumption throughout the dry season. The building rooftop is usually large enough to catch the rain water and maintain the flow. The size of underground tank should be enough to capture good quantity of water.
There are various other low-tech systems like surface water harvesting, pumping the water soaked in ground and storing it in cisterns. Before building the rain water harvesting system regions for high rainwater harvesting potential are to be detected with the help of rain water harvesting GIS maps. The main components of rain water harvesting system are; plenty of rainfall, catchment areas, pipes and gutters, storage system and tanks, filters and distribution system.
In urban populated areas good quality water is becoming scarce and costly. Rain water harvesting in urban areas meets the water supply and prevents the waste of water. Solar PV panels are being used to harvest the rain water in most parts of the country. Rain water harvesting is a boon during the scarce times. It not only meets the water supply but maintains our environment too.
Rain Water Harvesting Paragraph 350 words
Rain water harvesting is the accumulation, storage, preservation and filtration of rain water for future use of water as drinking water or for several other uses. The stored rain water has to be maintained regularly. The main purpose of rain water harvesting is to channel the rain water from the catchment surface such as roof top or other solid surface and then direct it through distribution system in to the storage tanks.
Benefits of Rain Water Harvesting
- Mostly during water restrains rain water harvesting provides independent supply of water where the clean water is costly for people in rural areas, the harvested water will be a cheap source of potable water and can be stored for long term. This practice is common by people in independent residence and buildings.
- In developed countries, harvested rain water is the source of supply and also reduces the cost of household water consumption. In fluctuating climates rain water harvesting systems are helpful in capturing the rain water when the rain falls. Most of the countries with unpredictable environment use rain water harvesting as it’s the economical and reliable source of clean water free of salinity and salts. It meets the water supply and prevents the wastage of water.
- Rainwater is specially used for irrigation facility. Soil ridges are built to trap rain water and prevent it to run off the slopes, this captures enough water for crops to grow. Dams and ponds can be constructed to store large quantity of water for irrigation of crops in future.
- Rain water harvesting lessens the impact of flooding. Due to rain water harvesting less water is directed towards sewer systems and it reduces the storm water to run off in fresh water bodies. This prevents the polluting of water bodies too.
- The underground water sources are gradually being strained in many regions. Construction of deeper wells is expensive and can damage the natural environment. Thus, this source of rainwater is dependable and effective. Harvested rain water can be used when the ground water supplies have been drained.
There are various benefits and uses of rain water harvesting. However harvesting systems have to be designed functioned and maintained to ensure the quality of water. The water also needs to be purified and filtered for use.
Rain Water Harvesting Paragraph 400 Words
Rain water harvesting is the process of collecting, storing and preserving water for using it later. The methods are traditional as well as modern and simple as well as complex. Some techniques are implemented by government with planning throughout the country and some are practiced independently by people at their home.
Methods for Rain Water Harvesting
Here are some methods for harvesting rain water:
Surface Water Storage System: The water directly collected on ground is the surface water. The water usually runs off the slopes and gathers towards the point of dispersion where it gets collected. This method enables the collection of water from the ground surface and with the help of drainage pipes the water is directed to the rivers, ponds, wells and other water bodies. Thus, the water can later be used for several purposes.
Rooftop System: This is a traditional method and is also practiced by individuals at home more so in the rural areas. In this method, the water that is collected on the rooftop of the building is directed towards the water containers or tanks through pipes. The water from the rooftops can also be directed towards the barrels or to refill the underground borehole.
Dams: The rain water is directly collected in dams and the accumulated surface water is directed towards the dam. The dam water is used for several purposes after purification. The water is also supplied for domestic use for the people.
Underground Tanks: Underground tanks are constructed for water storage. Water is directed to the underground tanks through pipelines.
Rain Saucer: Rain saucer is a great way to collect rain water directly. The rain saucer has a huge funnel like structure like an upside down umbrella on the top of the water container which directs the water in to the container.
Trenches: In this method rain water is directed towards the farms through trenches and the water is used for irrigation purpose.
Solar power panels: Solar power panels are used in most parts of the world for harvesting rain water. It provides good quality water and can be used as drinking water with simple filtration process.
Flooded forest: The harvesting of rain water can also be done by growing flooded forest. These are the forests that capture large amount of rain water.
Thus, there are various different methods that can be practiced for harvesting the rain water to prevent the insufficiency and waste of water. Water can be stored and used throughout the year with the help of this method.
Long Paragraph on Rain Water Harvesting
Rainwater harvesting is a crucial and practical approach to conserve one of our most precious natural resources: water. This method involves capturing, collecting, and storing rainwater that falls on rooftops, terraces, or even on the ground. The collected water can be stored in large tanks, reservoirs, or underground cisterns, making it available for various household or agricultural uses. Implementing rainwater harvesting can significantly reduce our reliance on traditional water sources, such as rivers or borewells, especially during periods of scarcity. By optimizing the use of rainwater, we can alleviate the pressure on our depleting groundwater tables and contribute to environmental sustainability. Additionally, the harvested rainwater, if treated properly, can be an excellent source of drinking water. This process not only ensures the efficient use of a free and abundant resource but also reduces the risk of flooding and soil erosion. In regions where water scarcity is a growing concern, rainwater harvesting offers a sustainable, eco-friendly, and cost-effective solution to ensure that every drop of water is put to good use.
