How does rainwater harvesting solve water shortage?

Harvesting rainwater allows the collection of large amounts of water and mitigates the effects of drought. Most rooftops provide the necessary platform for collecting water. Rainwater is mostly free from harmful chemicals, which makes it suitable for irrigation purposes.

What are the benefits of rain water harvesting?

The advantages of rainwater harvesting are:

• It is cost-effective.
• Conserves water.
• A source of water for landscape irrigation.
• It is a simple method and easy to practice.
• It reduces soil erosion and pollution of water bodies due to fertilizers and pesticides.

How does water harvesting help in times of drought?

It provides water when a drought occurs, can help mitigate flooding of low-lying areas, and reduces demand on wells which may enable groundwater levels to be sustained. It also helps in the availability of potable water, as rainwater is substantially free of salinity and other salts.

Do you know that the harvesting rain water is the best way to solve the problem of water scarcity What are the two different ways of harvesting rain water?

Answer: yes, rain water harvesting is the best way to control water scarcity. Broadly there are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting. Rainwater harvesting is the collection and storage of rain for reuse on-site, rather than allowing it to run off.

Why is rain water harvesting important in India give two reasons?

(i) India has seasonal erratic and uneven rainfall. Also, in the dry season, some parts of India have scarcity of water, e.g. in Rajasthan. (ii) With the help of rainwater harvesting techniques, water can be conserved and used during the dry season.

How is water harvested in a drought?

Collect rainwater using large barrels or cisterns for use in any number of water processes. Simply put them under a gutter and let it pour. Once collected, use the water for potable or non-potable use, depending on the process you put it through.

What is the conclusion of water?

Freshwater is a finite and limited resource on Earth and, increasingly, much of it is polluted, by both pathogenic microbes and chemical contaminants. Human demand for freshwater is increasing; in particular, water is required to irrigate crops to feed the rapidly expanding human population.

What is the conclusion of water conservation?

Conserving water reduces wear and tear on major resources such as water and wastewater treatment plants and the distribution systems that deliver water to the public. Using less water can also enable us to become more flexible during times when there is a water shortage.

What is your opinion about necessity of rainwater harvesting in India?

Need and Importance of Rainwater Harvesting in India Even in villages, some rainwater is required for irrigation, but the water that goes into drains is totally wasted. This surface run-off water also causes unnecessary soil erosion and floods. Certainly, we can collect rainwater and store it for these purposes.
