Essay on rain water conservation (100 words)

Rainwater harvesting is a technique that is used to store rainwater using different means in different resources for future use purpose (eg farming, etc.). Rainwater can be collected in natural reservoirs or artificial tanks.

Another method of collection is infiltration of surface water into subsurface aquifers before they are lost to surface overflow. Roof harvesting is also a method of collecting rainwater. It has great significance for people living in areas with low rainfall. They can continue harvesting seasonal crops using rainwater collected even in the lack of regular water supply. Whenever it rains , rainwater gets collected in man-made ponds or tanks.

In rainwater harvesting man-made resources or any natural resource like pond, lake etc., rainwater is stored at the same place where it falls from the roofs or the ground. The two main techniques of rainwater harvesting are storage for future use and recharge in the ground. It can be used for crop harvesting, gardening, toilets etc. The following are the benefits of rainwater harvesting at the individual or city-level:

  • This particularly helps institutions to reduce water supply bills.
  • Water recharged on the ground positively affects groundwater quality by weakening fluoride, nitrate and its salinity.
  • It contains almost neutral pH and zero hardness which makes it more efficient to use in homes, industries, institutions and other commercial establishments.
  • This can reduce the stress of public water supply sources.
  • Recharge of rainwater on land prevents the immersion of sea water in coastal areas.
  • It helps control urban flooding if people harvest rainwater from the roofs.
  • This reduces the water demand of the people of the municipality and in this way also reduces the energy consumption in the distribution of water in the city.

Rainwater harvesting means collecting rainwater in natural reservoirs or man-made tanks. It is a technique for collecting and storing rainwater for various purposes in future. Roof harvesting is the most common and easiest method of rainwater harvesting.

Using this technique we can collect a lot of clean rainwater during the rainy season. It can be stored for a long time for domestic purposes such as horticulture, livestock and irrigation etc. The following are the benefits of rainwater harvesting:

  • It helps in reducing water supply load and municipal electricity bills, free in rural areas
  • Water supply improves crop production and thus promotes food security.
  • Rainwater harvesting systems help reduce the insecurity of households or individuals in rural areas.
  • It provides easy and low cost water supply in the scarcity of water areas which helps in food security and income generation.
  • Tamil Nadu is one of the states in India and is now the first Indian state where rainwater harvesting has been made mandatory.
  • The Tamil Nadu state government has announced on 30 May 2014 to install around 50,000 rainwater harvesting structures at various locations in Chennai. So far, around 4,000 temples in Tamil Nadu have rain water tanks that serve in various rituals in temples and help recharge groundwater.

Every drop of rain water is like God’s blessing for the people on earth. Fresh rainwater falls on the ground like a pearl, so everyone should understand the importance of rainwater due to lack of natural water resources especially in developing areas and rural areas.

We should try to collect rain water without wasting the water running through the roofs and on the roads. We should bring our old traditional harvesting practices using new and effective techniques to supply easy water to all areas. The need for potable water of hundreds of thousands of people cannot be met only due to hand pumps, wells and other ground water level resources.

For many years, rainwater harvesting has been the most sustainable and effective way to provide water in water scarcity areas. Rainwater harvesting is capable of offering many benefits along with a very low cost method. It helps in various purposes like domestic works, field irrigation, livestock, agriculture and animal husbandry.

This directly and indirectly helps to rejuvenate the ground water level. Rainwater harvesting methods can be changed by rainwater harvesting methods of trenches, anicuts, dug wells, contour, etc., while other rainwater harvesting methods such as ground water tanks, ponds etc., ground water for at least four to six months. Help reduce the use of.

It is very effective in mountainous regions and desert areas of India and other countries. More and clean rainwater can be collected during the rainy season by creating large and clean water bodies.

Now-a-days, people have been dependent on the government system of water supply to supply water for their every need. The current scenario of water management and distribution in cities has been centralized by the government which has brought a huge gap of community responsibility in water management. It has slowly but regularly eliminated the old traditional water harvesting system.

Rainwater harvesting is again a new but old and effective technology for rainwater harvesting during the rainy season for the purpose of future use. It is being used frequently in various places in India to overcome the problems of water scarcity.

Rainwater harvesting is a good source of groundwater recharge in a natural way. However, due to rapid urbanization and development of cities on a large scale as well as the reduction in the amount of rainwater, the groundwater level is decreasing day by day.

Rainwater harvesting is the way to reduce groundwater use as well as always maintain its level in the future. In the dry regions of India and other countries, it is more important to meet the demand of water for different purposes. The following points that prove the fact of harvesting rainwater are mentioned:

  • It plays a great role in preventing groundwater degradation and improving the groundwater table.
  • This helps in improving the water quality in aquifers.
  • This is to conserve more water and prevent surface water runoff during the monsoon.
  • It helps in reducing soil erosion.
  • This is to bring the old tradition of water conservation among the people.
  • Rainwater can be harvested better by using the following methods such as surface runoff harvesting and rainwater harvesting above the roof. two
  • Both very effective methods help to increase the level of ground water and meet the requirement of water supply in an easy and cost effective manner.

Rainwater harvesting is the collection and storage of rainwater in natural resources or artificially designed resources to prevent water runoff and meet future water scarcity. The amount of water harvesting is influenced by factors such as the frequency of rainfall, the amount of rainfall, how rainwater is collected, and the size of the resources to collect water.

The ground water level is falling day by day due to various reasons like deforestation and ecological imbalance. Demand for water supply increases, especially in urban areas, due to continuous increase in the level of urbanization and industrialization. This is leading to overuse of ground water and thus lower levels.

In the future the risk of water scarcity is increased to a great extent and not following some effective solutions can be life-threatening. Water harvesting is very helpful and caters to various needs such as recharging the ground water level, reducing the electricity bill in the water supply and providing the water supply anytime needed.

It is estimated that a 1 meter rise in the water level saves about 0.4 kWh of electricity.

Why rainwater harvesting is necessary:

Rainwater harvesting by people is very important in all areas. It is good to reduce the fear of water scarcity in the future. The following points prove the fact why rainwater harvesting is necessary:

  • Surface water cannot meet the demand for water for various purposes.
  • Everyone is dependent on ground water for their every need.
  • Groundwater levels are steadily decreasing due to deforestation, rapid urbanization, rainwater infiltration to sub-soil, etc.
  • Rainwater conservation maintains water levels in natural water resources.
  • This reduces the chances of watering the roads, reduces the risk of soil erosion and improves water quality.

The following are the main techniques of rainwater harvesting:

  • Collecting rainwater on the surface for future use.
  • Recharge of ground water.
  • Collecting rainwater on the surface is a very effective and traditional technique. This can be done using small ponds, underground tanks, dams, weeds etc.
    • However, groundwater recharging techniques are a new concept of harvesting. This can be done using dug wells, pits, trenches, hand pumps, recharge wells, recharge shafts, recharging lateral shafts with borewells, dispersion techniques (means of diffusion of water to stream, sewer, etc.) .
