Rain water flows down the hills in the form of small streams which join together to form rivers and lakes. And this is the important and the natural source of water for the living beings. Some of the rain water percolates down the earth until it reaches the hard surface. There it collects to form a large underground water reservoir.
August 11, By Victor Introduction: Rainfall is a good source of water for both domestic and commercial use. Falling rain is always a welcome sight especially after weather characterized by extremely high temperatures.
What is the Meaning of Rainwater Harvesting? Rainwater harvesting is the process of collecting rainwater and putting it to good use. There are different ways in which this task can be accomplished. Rainwater harvesting refers to the trapping and storing of rainwater so that it can be used at a later time when the need arises.
As the rain falls, water is directed to a suitable collection point. Harvesting mainly entails gathering something from its natural source. Rainwater harvesting, from the common definition of harvesting, is a process that involves collecting rainwater and increasing its value by eliminating impurities or directing it to places where its use is highly required.
The only difference is that now better methods have been developed to make the process a great success. New technologies have come into play and are now making the process easier and more efficient.
Methods of Rainwater Harvesting There are many ways in which rainwater can be harvested. Some of these methods are very effective and can aid in the collection of a lot of water even for commercial activities while others are only suitable for harvesting water meant for domestic use.
Every system has its merits and demerits. These are the common methods of rainwater harvesting: Surface Water Collection Systems: When rainwater falls on the surface of the earth, it usually flows down slopes as it moves towards a point of depression where the moving water can collect.
Surface water collection systems enable the collection of ground surface rainwater before it flows to other locations. Examples of such systems include rivers, ponds, and wells. Drainage pipes can be used to direct water into these systems.
Water can then be fetched from these sources and then used for other purposes. These can also be used to harvest rainwater. They can be used to direct rainwater that falls on the roof of a building into containers or tanks.
These tanks are usually elevated so that when the tap is opened, water flows at a high pressure. This method of rainwater harvesting is good because the accumulated water is mostly clean and usually requires no further treatment to make it fit for human use.
These are barriers that are designed to trap water.
Rainwater harvesting is the process of collecting rainwater and putting it to good use. There are different ways in which this task can be accomplished. Rainwater harvesting refers to the trapping and storing of rainwater so that it can be used at a later time when the need arises. Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run grupobittia.comter can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit (well, shaft, or borehole), a reservoir with percolation, or collected from dew or fog with nets or other tools. Its uses include water for gardens, livestock. Rainwater Harvesting Introduction The objective of water harvesting in India differs between urban and rural areas. In urban areas, emphasis is put on increasing groundwater recharge and managing storm water. On the other hand, in rural areas securing water is .
Rainwater can accumulate directly in them or drainage systems can be created to direct water into them. Water collected in dams is mostly used for irrigation purposes or treated and then distributed for domestic use.
They can also be used to harvest a lot of water because of the way in which they are modeled. Unlike ponds, measures are put in place to reduce the amount of water draining into the ground.
These are also ideal for collecting rainwater.
They are constructed by digging into the ground and creating a space which is then cemented to reduce water infiltration. The top is also sealed and water is obtained through pipes directed into the tank. To get water out, pumps are used. Underground tanks are wonderful for harvesting rainwater because the rate of evaporation is reduced since they are located underground where sunlight does not really penetrate.
Sometimes one can decide to collect rainwater directly as it falls from the sky by using a rain-saucer.An Essay On The Need For Rainwater Harvesting In India. Why rainwater harvesting?In many regions of the world, clean drinking water is not always available and this is only possible with tremendous investment costs and expenditure.
Rainwater is a free source and relatively clean and with proper treatment it can be even used as a potable water source. ADVERTISEMENTS: Rain Water Harvesting in India: Need, Methods and other Details!
Water is an important natural resource and is the very basis of our life. We use water for drinking, irrigation, industry, transport and for the production of hydro-electricity.
Rainwater Harvesting Rainwater harvesting means collection of rainwater and to store it in different containers applying proper means to keep the water fit for any use.
The rainwater may fall anywhere on the earth, but that must not be allowed to roll or run downwards to get evaporated or to seep into dirt or filth and thus become unfit for use.
