Rain Water Harvesting Essay – For Students and Children In English

Last Updated on

Rainwater harvesting involves the collection and storage of rainwater into the natural reservoirs or artificial reservoirs in order to prevent the surface water runoff. Rainwater harvesting is a process of collecting and storing rainwater for using it as a backup supply of freshwater to meet everyday domestic and agricultural requirements, especially when water becomes scarcely available. There are several methods by which we can collect rainwater flowing from our rooftops, ditches, gardens, fields, forests and other locations.

Long and Short Essay on Rain Water Harvesting

Essay 1 (250 words)

Every drop of rainwater is like the blessings of God to the people on the earth. Fresh rain water falls on the ground like pearls, so everyone should understand the importance of rainwater especially in developing regions and rural areas lack natural water resources.

We should try to collect rainwater without wasting through rooftops and along with streets runoff. We should bring our old traditional harvesting practices using new and effective technologies to make easy water supply in all the regions. As only hand pumps, wells, and other resources of groundwater levels cannot fulfill the potable water need of hundreds of thousands of people.

Rainwater harvesting is the most sustainable and effective way for many years to make water available in the areas lacking water. Rainwater harvesting is a very low-cost method along with lots of benefits. It helps in various purposes like household works, field irrigation, livestock, agriculture and animal husbandry.

It helps in rejuvenating the groundwater levels both directly and indirectly manner. Groundwater level can be replenished by rainwater harvesting methods of trenches, anicut dams, dug wells, contour, etc whereas other rainwater harvesting methods like underground water tanks, ponds, etc help in reducing the use of groundwater for at least four to six months. It is very effective in the hilly regions and desert regions of India and other countries. More and cleaner rainwater can be collected in the rainy season by making large and clean water bodies.

Nowadays, people have been dependent on the government system of water supply for getting water for their every need. The present scenario of water management and distribution in the cities has been centralized by the government which has brought a big gap of community responsibility in water management. It has slowly but regularly finished the old traditional water harvesting system.

Rainwater harvesting is again a new but old and effective technique of collecting rainwater during the rainy season for future usage purposes. It is being frequently used in various places of India to overcome the problems of lack of water. Rainwater harvesting is a good source of groundwater recharge in a natural way.

However, the groundwater level is getting less day by day because of the rapid urbanization and city development at a huge level as well as a reduction in percolation of the rainwater to the ground. Rainwater harvesting is the way to reduce the use of groundwater as well as maintain its level forever in the future. It is of more importance to the drought regions of India and other countries to supply the demands of water for various purposes. Following are mentioned points proving the fact why to harvest rainwater:

  • It plays a great role in protecting the groundwater decline and improving the groundwater table.
  • It helps in improving the water quality in aquifers.
  • It is to conserve more water and prevent surface water runoff during the monsoon.
  • It helps in reducing soil erosion.
  • It is to bring the old tradition of water conservation among people.

Rainwater can be harvested in a better way using the following methods like surface runoff harvesting and rooftop rainwater harvesting. Both are very effective methods that help in enhancing the level of groundwater and fulfill the need for water supply in an easy and cost-effective way.

Rainwater harvesting is the collection and storage of rainwater in the natural resources or artificially designed resources to prevent water runoff and fulfill the lack of water in the future. The quantity of water harvesting is affected by the number of factors like frequency of rainfall, the quantity of rainfall, way of collecting rainwater, and the size of resources to collect water. The groundwater level is getting depleted day by day due to various reasons like deforestation and ecological imbalance.

The increasing level of urbanization and industrialization constantly increases the demand for water supply, especially in urban areas. It results in the overuse of groundwater and thus going low level. The risk of water scarcity in the future has been increased to a great extent and can be life-threatening if some effective solutions are not followed.

Water harvesting is very helpful and fulfill various need like recharging the groundwater level, reduces electricity bill spend in supplying water and provide easy water supply anytime when required. It is estimated that a 1-meter rise in the water level saves around 0.4 kWh of electricity.

Why Rain Water Harvesting is Necessary:

Rainwater harvesting is very necessary to be practiced by the people in all regions. It is good to reduce the fear of water scarcity in the future. Following are the points proving the fact that why rainwater harvesting is necessary:

  • Surface water cannot fulfill the demand of water for various purposes.
  • Everyone depends on the groundwater for their every need.
  • Deforestation, rapid urbanization, rainwater infiltration to the sub-soil, etc reasons are continuously decreasing the level of groundwater.
  • Rainwater conservation maintains the level of water in natural water resources.
  • It reduces the chance of flooding of water on the roads, reduces the risk of soil erosion and improves the quality of water.

Following are the main techniques of rainwater harvesting:

  • Collecting rainwater to the surface for future use.
  • Recharging the groundwater.

Collecting rainwater to the surface is a very effective and traditional technique. It can be done using small ponds, underground tanks, dams, weirs, etc. However, the groundwater recharging technique is a new concept of harvesting. It can be done using dug wells, pits, trenches, hand pumps, recharge wells, recharge shafts, recharge lateral shafts with bore wells, spreading technique (means spread of water to the stream, Nala, etc).
