Rain water harvesting
Water is an essential resource. No one can live and survive without water. Hence, we should not let the source of the life waste, instead we must store it. We can do so by the methods of Rainwater Harvesting. Rainwater Harvesting refers to the process of collecting and storing of rainwater. Rainwater harvesting helps in providing drinking water, water for irrigation, agricultural purposes or for groundwater recharge. It is one of the best solutions to water problem in the areas having inadequate water resources. Rainwater systems are simple to construct. Usually, rainwater is either harvested from the ground or from a roof. During the rainy seasons, the rain water can be collected and stored in the tanks. There are many methods to harvest the rainwater. Usually, the methods used are: Catchments Areas i.e. the areas which receive rainfall directly. In this, paved areas like roof of a building or unpaved area such as open ground or lawns can be used for the catchment areas. Ground catchment techniques has more chances of collecting water from the larger surface areas. Storage system: It is designed according to the amount of water that is needed to be stored. Storage system must be sealed and does not leak. Chlorine must be put from time to time to keep the water clean. Conveyance systems which transfer the rainwater collected on the rooftops to the storage tanks and that is done by making connections to one or more down-pipes connected to the rooftop gutters or pipes. The gutters must be made as such that if it rain starts,the dirt will be washed into the down-pipe and clean water comes out.
Answer:
Rainwater Harvesting is one of the most commonly used methods to save water. It refers to storing of rainwater for various uses. The notion behind rainwater harvesting is to not waste the rainwater and prevent it from running off. In other words, it is done to collect rainwater using simple mechanisms. This method is very useful considering the water scarcity that is happening in India. Moreover, rainwater harvesting is so easy that almost anyone can do it. We must encourage this practice to help people get access to clean water easily without any cost.
Importance of Rainwater Harvesting
As we know by now, rainwater harvesting is very easy and economical. Following the water scarcity in so many parts of the world, rainwater harvesting has become the need of the hour. It must be practiced by people of all regions. This will also give them a sense of comfort in knowing that they won’t have to face water scarcity.
Furthermore, rainwater harvesting holds more importance than you actually think it does. As we know that surface water is not enough to meet the demands of the people, we can get additional help from rainwater. Also, most people now depend on groundwater for their uses. Many houses and even flats have submersible pumps in their place. The groundwater is decreasing day by day because of excessive usage, deforestation, urbanization and more.
Thus, when we practice rainwater harvesting, it can maintain the level of the groundwater. That way, we all can make use of groundwater as it will keep on replenishing through rainwater harvesting. Moreover, rainwater harvesting prevents water from logging on roads. It also reduces the chances of soil erosion. Most importantly, rainwater harvesting improves the quality of water which we consume, as it is the purest form of water.
