Rainwater Harvesting is a useful solution for the water crisis. It is invented for providing pure water to people as per their regular and other uses. For a better understanding of readers, we have created some of the important paragraphs elaborating on the meaning of Rain Water Harvesting, its need, etc. Kindly read it as per your need.
Short and Long Paragraphs on Rain Water Harvesting
Paragraph 1 – 100 Words
Rain Water Harvesting is the best method for conserving rainwater. The purity of water available for humans is degraded and that is why people are facing a water crisis. For all of these reasons, a method of collecting rainwater and processing it into human use is developed, and it is termed as Rain Water Harvesting.
In Ancient days, Rainwater harvesting was a common method. This ancient practice is evolved and for utilizing the natural droplets of rainwater, a well-developed model is established. Rain water harvesting is common in the areas that are facing scarcity of water. India, Australia, Canada, Israel, etc countries are using well-equipped methods for rainwater harvesting.
Paragraph 2 – 120 Words
Rain Water Harvesting is the method for collecting rainwater for human use. The procedure of refining the rainwater is useful for various purposes. Rainwater is considered as one of the best and cheap methods to be installed in households, offices, industrial setups, and other commercial complexes. There are two types of Rain Water Harvesting Systems:
- Surface Runoff Rainwater Harvesting: Surface Runoff Rainwater Harvesting is the well-equipped rainwater collection tanks/ponds from the flowing rainwater on man-made constructions. The wastage of rainwater on the surface of roads, parks, gardens, etc is collected and processed for further use.
- Roof-Top Rain Water Harvesting: Roof-Top Rain Water Harvesting is the setup on the terrace area of buildings for the collection of rainwater. The main motive of this establishment to process the raindrops for further use.
Paragraph 3 – 150 Words
Rain Water Harvesting is one of the best methods for coping with the scarcity of water. The basic components of Rainwater Harvesting System involve:
- Catchment: The surface which directly receives the rainwater is called a catchment. It can be a rooftop of buildings, households or pavements of roads, gardens, and man-made areas.
- Coarse Mesh: The mesh setup for filtering the small pieces of scrap on the end of the catchment is called as coarse mesh.
- Gutters: Gutters are the channels setup around the catchment areas for connecting the rainwater to the final storage tank.
- Filters: Filters are setup on the top of the storage tank for filtering the fine particles of dust and dirt particles, to provide pure water in the storage tank.
- First-Flushing: First flushing tanks are the small tank setup on the edge of the catchment; it flushes out the first rainwater, as first rainwater is contaminated with acid and other harmful chemicals.
- Conduits: The pipeline that connects the catchment area to the storage tank is called a conduit.
Paragraph 4 – 200 Words
Rain Water Harvesting is a specialized system for saving and filtering rainwater. There are various benefits of rainwater harvesting. It involves farming, household purposes, commercial use, etc. The quality of water is degraded due to harmful chemicals, even water available for drinking purpose is hardly sufficient for society.
The groundwater level is also decreasing day by day. For resolving these problems, rainwater is treated as an important source of natural water. Water is naturally available in various springs, streams, rivers, etc. Rainwater is a blessing for natural water reservoirs. Its conservation is important.
It helps in preventing the water-logging from roads. Soil Erosion is also one of the serious issue caused due to heavy rainfall, rainwater harvesting can solve this issue. The benefits are more than we think. The filtered water can be used in the household for drinking, cooking and sanitation purposes.
In the southern part of India, the rainwater harvesting system is common. The collection of rainwater and reusing it can reduce the water bills. The expenditure on the maintenance of the rainwater harvesting system is very low. Rainwater is precious to the world and it’s important to collect and reuse it.
Paragraph 4 – 250 Words
Rain Water Harvesting is the method for collecting and recycling the rainwater. The procedure of recycling rainwater is beneficial for general use. A storage tank is built on the premises of houses/offices for collecting the rainwater from the catchment area. Storage tanks are equipped with filters. There are various types of filters are installed in the storage tanks.
Sand Filters, Charcoal Filters, PVC Filters, Stainless Steel Filters are some of the filters used in storage tanks. In Dewas (M.P., India), most of the households have installed rainwater harvesting systems. Regions facing droughts on yearly basis use a rainwater harvesting system for future use. Sometimes rainwater harvesting setups are considered as costly due to the following reasons:
Catchment Structure: The nature of catchment affects the installation of the system. The complexity of the structure of the rooftop, roads, and other paved surfaces can be a reason for high expenditure upon the installation.
Advanced Filters Range: There is a various advanced range of filters available in the market; this can be a reason affecting the amount of installation of a rainwater harvesting system.
Storage Tank Capacity: The storage tank is also can be the reason behind spending a heavy amount on the system.
The Tendency of Water Runoff: Surface runoff is one of the factors that can demand a heavy amount to be spent on the rainwater harvesting system.
Besides all these factors rainwater harvesting is considered one of the beneficial techniques for availing pure water to households, agriculture farms and other commercial purposes.
